Large pigeon lost to science for 140 years rediscovered in Papua New Guinea

PRESS RELEASE:

A team of scientists and conservationists has rediscovered the elusive Black-naped Pheasant-pigeon, a large, ground-dwelling pigeon that only lives on Fergusson Island, a rugged island in the D’Entrecasteaux Archipelago off eastern Papua New Guinea. Like other pheasant-pigeons, the Black-naped Pheasant-pigeon has a broad and laterally compressed tail, which along with its size, makes it closely resemble a pheasant. The photographs and video are the first time the long-lost bird has been documented by scientists since 1882, when it was first described. Ornithologists know very little about the species but believe that the population on Fergusson is very small and decreasing.

The research team photographed the pheasant-pigeon with a remote camera trap at the end of a month-long search of Fergusson.

“When we collected the camera traps, I figured there was less than a one percent chance of getting a photo of the Black-naped Pheasant-pigeon,” said Jordan Boersma, postdoctoral researcher at Cornell Lab of Ornithology and co-leader of the expedition team. “Then as I was scrolling through the photos, I was stunned by this photo of this bird walking right past our camera.”

“As well as giving hope for searches for other lost species, the detailed information collected by the team has provided a basis for conservation of this extremely rare bird, which must indeed be highly threatened, together with the other unique species of Fergusson Island.”

The expedition team – which included local Papua New Guineans working with Papua New Guinea National Museum, Cornell Lab of Ornithology and the American Bird Conservancy (BirdLife USA) – arrived on Fergusson in early September 2022. They spent a month traveling around the island, interviewing local community members to identify locations to set up camera traps in hopes of finding the pheasant-pigeon. The steep, mountainous terrain on Fergusson Island made searching for the bird extremely challenging.

“It wasn’t until we reached villages on the western slope of Mt. Kilkerran that we started meeting hunters who had seen and heard the pheasant-pigeon,” said Jason Gregg, conservation biologist and a co-leader of the expedition team. “We became more confident about the local name of the bird, which is ‘Auwo,’ and felt like we were getting closer to the core habitat of where the black-naped pheasant-pigeon lives.”

The expedition was the first-ever camera trapping study conducted on Fergusson Island. The team placed 12 camera traps on the slopes of Mt. Kilkerran, Fergusson’s highest mountain, and deployed an additional eight cameras in locations where local hunters had reported seeing the pheasant-pigeon in the past.

“When we finally found the black-naped pheasant-pigeon, it was during the final hours of the expedition,” said Doka Nason, the member of the team who set up the camera trap that eventually photographed the lost bird. “When I saw the photos, I was incredibly excited.”

A local hunter named Augustin Gregory in the village of Duda Ununa west of Mt. Kilkerran provided a breakthrough lead on where to find the bird. Gregory reported seeing the pheasant-pigeon on multiple occasions in an area with steep ridges and valleys and described hearing the bird’s distinctive calls, which is similar to other species of pheasant-pigeons.

Following Gregory’s advice, the team set up cameras in an area of dense forest. A camera placed on a ridge at 3,200 feet (1000 meters) near the Kwama River above Duda Ununa eventually captured the Black-naped Pheasant-pigeon walking on the forest floor two days before the team was scheduled to leave the island.

“This rediscovery is an incredible beacon of hope for other birds that have been lost for a half century or more. The terrain the team searched was incredibly difficult, but their determination never wavered, even though so few people could remember seeing the pheasant-pigeon in recent decades.”

Christina Biggs, manager for the Search for Lost Species at Re:wild

Several members of the team have attempted to find the black-naped pheasant pigeon before. A two-week survey in 2019 by Boersma, Gregg and Nason didn’t find any traces of the bird, though it did gather reports from local hunters of a bird that could have been the pheasant-pigeon. The results from that survey helped to determine locations for the team to search in 2022.

“The communities were very excited when they saw the survey results, because many people hadn’t seen or heard of the bird until we began our project and got the camera trap photos,” said Serena Ketaloya, a conservationist from Milne Bay, Papua New Guinea. “They are now looking forward to working with us to try to protect the pheasant-pigeon.”

The team’s findings suggest that the pheasant-pigeon is likely to be extremely rare. The rugged and inaccessible forest where they rediscovered the species could be the last stronghold for the black-naped pheasant-pigeon on Fegusson.

The expedition was supported by American Bird Conservancy and the Search for Lost Birds, a collaboration between BirdLife International, American Bird Conservancy and Re:wild. The Search for Lost Birds identified the pheasant-pigeon for an expedition after a global review revealed it was one of a few bird species that have been lost to science for more than a century.

Rare Pigeon Species Rediscovered in Papua New Guinea After 140 Years

An expedition team made up of scientists and conservationists began their search to rediscover the bird in September

By Kimberlee Speakman 

Published on November 17, 2022 06:46 PM

A rare pigeon species was documented for the first time in 140 years after a group of scientists and conservationists got photos of a black-naped pheasant-pigeon on Fergusson Island, a small island off the coast of eastern Papua New Guinea.

“After a month of searching, seeing those first photos of the pheasant-pigeon felt like finding a unicorn,” said John C. Mittermeier, the director of the lost birds program at the American Bird Conservancy and the co-leader of the expedition. “It is the kind of moment you dream about your entire life as a conservationist and birdwatcher.”

The last known time this elusive bird — which can be identified by its large size and pheasant-like tail — was found and documented was in 1882.

The expedition team sought to rediscover the animal and set out in early September to find it. They traveled across the island and spoke with different villagers and community members to understand what locations would be best for camera traps to capture the bird.

The interviews led them to the slope of Mt. Kilkerran; there, the group set up 12 camera traps along the mountain slopes and eight additional cameras where hunters recalled previously seeing the birds.

One specific tip from a hunter from the Duda Ununa village near Mt. Kilkerran led to the find. The hunter, Augustin Gregory, told the team he had seen the bird and heard its calls in an area with steep ridges and valleys near the village.

The team set up a camera, per Gregory’s reports, on a ridge near the Kwama River, and that device captured photos of the bird two days before the team was scheduled to leave the island.

“When we collected the camera traps, I figured there was less than a one percent chance of getting a photo of the black-naped pheasant-pigeon,” said Jordan Boersma, conservation biologist and co-leader of the expedition team. “The,n as I was scrolling through the photos, I was stunned by this photo of this bird walking right past our camera.”

A previous expedition to find the black-naped pheasant-pigeon in 2019 was unsuccessful. However, scientists used the information from that trip to help them identify locations to set up cameras for their 2022 expedition.

Prime Minister James Marape has reiterated his stance that large carbon emitters hold a “moral obligation and the bigger responsibility” when it comes to addressing the ongoing climate crisis. This was stated during a panel discussion at the World Economic Forum (WEF) Annual Meeting in Davos, where he responded to questions regarding the implications of former President Donald Trump’s withdrawal of the United States from the Paris Agreement.

In a dialogue facilitated by New York Times journalist David Gelles, PM Marape was asked how this withdrawal is perceived in Papua New Guinea, a country recognized for its rich biodiversity, tropical forests, and significant ocean resources that serve as vital carbon sinks. This question comes at a time when the management of climate change is a growing global concern.

Prime Minister Marape emphasized that it is incumbent upon the largest carbon producers to take greater responsibility, especially as they contribute significantly to global emissions while nations like Papua New Guinea bear the brunt of climate impacts despite having a smaller carbon footprint. He remarked, “While it is not my place to advise the government of America, it is prudent that the biggest holder of carbon footprint takes the greater responsibility because much of the burden is being borne by those of us with the least carbon footprint.”

The Prime Minister called for a shift in perspective among global leaders, urging them to prioritize global interests over national agendas. He stated, “There is a moral responsibility by each global leader to think from the global perspective instead of from their own national-interest perspective,” underscoring the urgency of the climate situation. Marape warned that “we are at a tipping point, almost reaching the end of Earth’s sustainability level. If this planet sinks, we all sink with it. There is no second Earth.”

As the conversation shifted towards sustainable resource management, PM Marape highlighted Papua New Guinea’s significant potential in clean energy, forestry, and marine resources, asserting that “PNG has a lot of clean energy alternatives.” He expressed optimism about the country’s role in the upcoming Asian century, stating their readiness to contribute to forest resource management and the sustainable management of oceans.

“The ocean is 70 percent of the planet,” he noted, emphasizing the crucial role it plays in global environmental health. Through collaboration and innovation in sustainable practices, PM Marape aims to establish Papua New Guinea as a key player in global efforts to combat climate change and promote ecological stewardship. https://www.facebook.com/share/p/19rsUFVyJ

This bird hadn’t been documented by scientists since 1882. Then they captured video of it in Papua New Guinea

CNN — A bird thought to be extinct for 140 years has been rediscovered in the forests of Papua New Guinea.

The black-naped pheasant-pigeon was documented by scientists for the first and last time in 1882, according to a news release from nonprofit Re:wild, which helped fund the search effort.

Rediscovering the bird required an expedition team to spend a grueling month on Fergusson, a rugged island in the D’Entrecasteaux Archipelago off eastern Papua New Guinea where the bird was originally documented. The team consisted of local staff at the Papua New Guinea National Museum as well as international scientists from the Cornell Lab of Ornithology and the American Bird Conservancy.

Fergusson Island is covered in rugged, mountainous terrain – making the expedition especially challenging for the scientists. Many members of the community told the team that they hadn’t seen the black-naped pheasant-pigeon in decades, says the news release.

But just two days before the researchers were scheduled to leave the island, a camera trap captured footage of the exceptionally rare bird.

“After a month of searching, seeing those first photos of the pheasant-pigeon felt like finding a unicorn,” John C. Mittermeier, director of the lost birds program at American Bird Conservancy and co-leader of the expedition, said in the release. “It is the kind of moment you dream about your entire life as a conservationist and birdwatcher.”

The black-naped pheasant-pigeon is a large, ground-dwelling pigeon with a broad tail, according to the release. Scientists still know little about the species and believe the population is small and decreasing.

Insight from local residents was crucial for the scientists to track down the elusive bird.

“It wasn’t until we reached villages on the western slope of Mt. Kilkerran that we started meeting hunters who had seen and heard the pheasant-pigeon,” Jason Gregg, a conservation biologist and co-leader of the expedition team, said in the release. “We became more confident about the local name of the bird, which is ‘Auwo,’ and felt like we were getting closer to the core habitat of where the black-naped pheasant-pigeon lives.”

They placed a total of 12 camera traps on the slopes of Mt. Kilkerran, which is the island’s highest mountain. And they placed another eight cameras in locations where local hunters reported seeing the bird in the past.

A hunter named Augustin Gregory, based in the mountain village Duda Ununa, provided the final breakthrough that helped scientists locate the pheasant-pigeon.

Gregory told the team that he had seen the black-naped pheasant-pigeon in an area with “steep ridges and valleys,” says the news release. And he had heard the bird’s distinctive calls.

So the expedition team placed a camera on a 3,200-foot high ridge near the Kwama River above Duda Ununa, according to the release. And finally, just as their trip was ending, they captured footage of the bird walking on the forest floor.

The discovery was a shock for the scientists and the local community alike.

“The communities were very excited when they saw the survey results, because many people hadn’t seen or heard of the bird until we began our project and got the camera trap photos,” said Serena Ketaloya, a conservationist from Milne Bay, Papua New Guinea, in the news release. “They are now looking forward to working with us to try to protect the pheasant-pigeon.”

It’s still not clear just how many of the black-naped pheasant-pigeon are left, and the rugged terrain will make identifying the population difficult. A two-week survey in 2019 failed to find any proof of the bird, although it did discover some reports from hunters that helped determine the locations for the 2022 expedition.

And the discovery might provide hope that other bird species thought extinct are still out there somewhere.

“This rediscovery is an incredible beacon of hope for other birds that have been lost for a half century or more,” said Christina Biggs, the manager for the Search for Lost Species at Re:wild, in the release. “The terrain the team searched was incredibly difficult, but their determination never wavered, even though so few people could remember seeing the pheasant-pigeon in recent decades.”

“Nature is a priori” -Schelling

Thanks to milliern for his commentary on and reflections about an exchange Professor Corey Anton, myself, and others have been having on YouTube. I’m reposting my comment to him below:

I wanted to offer a few clarifications of my own position. I don’t normally think of myself as a “Heideggerian,” though I suppose most people who take the time to really read Heidegger are irrevocably transformed in some way. I’m one of those who has spent considerable time with his texts and ideas. While he has changed the way I think, I’ve nonetheless come to differ with him (as I understand him) in important ways. I’m not at all convinced that ‘human’ being, or Dasein, is the only significant mode of being. Nature, too, is significant. In fact, like Schelling, I would say the significance of human being could only be derived from that of Nature’s original being. Nature is a priori, not mind. Nature generated mind; mind is but a higher potency of Nature’s subjectivity. So I’m more Schellingian than Hedeggerian. If Heidegger spoke of a “groundless ground,” it’s because he was a close reader of Schelling, who more than a century earlier had recorded his encounter with das unvordenkliche (“the unprethinkable”). I don’t think this “groundless ground” should be identified with the Kantian transcendental ego or ding an sich. The groundless ground, the abyss or abgrund (a term Schelling borrowed from the esotericist Böhme), is the mother of both phenomena and noumena. Das Unvordenkliche is not born of the phenomenal-instrumental nature known to physicists and biologist. Nor is it born of the Ego, as in the Fichtean interpretation of Kant. Rather, like Spinoza before him, and Whitehead after him, Schelling distinguished between Natura naturans and Natura naturata. The former is Nature ‘naturing,’ the latter Nature ‘natured.’ The former is process, the latter is product. The former is alive, the latter is dead. Schelling’s Nature is not the external/extended material world of law-abiding physical particles that is supposed to exist by mathematical physicists. His Nature is not a ground, but a creative abyss. To know such a world, you must not march off to explain and control it as though it were entirely made up of plainly visible bodies,–as modern techno-scientific materialism has–, you must humbly seek to understand and communicate with its mostly invisible sensitivities (i.e., with its soul).

Unlike Kant’s mechanized Newtonian universe, Schelling perceived the earth and her creatures, the sun, planets, and other stars–yes as mathematically ordered–, but also as animate gods, as living beings creative of beautiful worlds. Where scientific materialism sees only dead nature (that is, nature natured), organic realism (what I refer to Schelling and Whitehead’s  philosophies of nature as) perceives nature naturing. What is unprethinkable about ourselves and about the world is this ongoing creative process–call it “cosmogenesis,” call it “Creativity,” call it “the One and All,” or God, if you want. Whatever “It” is, it’s before subject and object. It is before mind and matter. Schelling is usually lumped in with the idealists, but it was Heidegger himself (in his lectures on Schelling’s 1809 book on human freedom) who first suggested that Schelling’s Naturphilosophie in fact subverted the entire German Idealist project from the inside out. I’d argue he has more in common with the radical empiricist James than with any idealist, and especially with James’ philosophical inheritor at Harvard, the mathematical adept turned cosmologist Alfred North Whitehead.

Speaking of which, I noticed you are interested in Einstein, ether, space-time, etc…. I wonder if you’ve run across Whitehead’s alternative ether theory (the “ether of events” or “extensive continuum”)? I’ve written about it HERE. I’d be curious to know your take on his organic cosmological scheme.

Decolonize climate adaptation research

Climate-forced population displacement is among the greatest human rights issues of our time, presenting unprecedented challenges to communities and the governments responsible for protecting them. Sea level rise, heat, drought, and wildfires will cause people to move, losing homes and places they love, often with no ability to return. Indigenous Peoples have done the least to cause this crisis and face the loss of lands and connections to ancestral, cultural, and spiritual heritage. To ensure that their right to self-determination is protected and the horrific legacy of government-forced relocations is not repeated, communities must lead and define research on climate-forced displacement and managed retreat that involves them and the lands upon which they dwell and subsist. A focus on human rights, and decolonization of research to change institutional structures of knowledge production, can help communities define their future in a climate-altered world.

The government responsibility to protect people may require relocation against peoples’ will. Determining which communities are most likely to encounter displacement requires sophisticated assessment of the vulnerability of a community’s ecosystem, but also its social, economic, and political structures. Human rights principles, which include rights to food, to safe and sanitary housing, and to water, must be embedded in any relocation governance framework. The right to self-determination ensures that communities make the decision of whether, when, and how relocation will occur and that cultural and spiritual heritage is protected if relocation is the best strategy.

Human rights principles also ensure that racial and economic inequities, legacies of colonization and slavery, are addressed when responding to climate-forced displacement. Scholars continue colonization when Indigenous Tribes are not represented in, or consulted for permission to do, research on their communities and lands. Decolonization is the restoration of cultural practices, spirituality, and values that were taken away or abandoned through colonization and that are important for survival, well-being, and subsistence lifestyles. Decolonization advances and empowers Indigenous Peoples and stops perpetuating their subjugation and exploitation.

Indigenous-led research can help determine whether inclusion of human rights protections averts or minimizes severe consequences associated with government-mandated relocation. For example, in a letter to the US National Science Foundation expressing concerns with its Navigating the New Arctic program, four Alaska Native organizations explained the danger and damage to their communities when outside academics define food security, resilience, and adaptation, highlighting the importance of Indigenous scholarship and voices in research.*

Self-determination and decolonization mean that communities control the narrative about how the climate crisis affects them. Colonization continues when non-Indigenous scholars write narratives about “vanishing cultures.” The Alaska Native Science Commission and Inuit Circumpolar Council provide a promising model, having protocols that ensure Indigenous communities lead research efforts, defining the questions and methodologies. Non-Indigenous scholars need to build relationships and trust with Tribes before submitting funding applications to understand how skills offered by academic researchers can benefit and complement skills and expertise of Indigenous knowledge holders.

Community-based environmental monitoring, and coproduction of knowledge, are important decolonizing tools that can facilitate empowerment and capacity building. Community-based monitoring is important to understand local ecosystem change, which is critical to implementing community-based adaptation strategies; global, regional, and national climate change assessments generally aggregate information above the level of resolution required for effective community policy.

We reflect here on our experience in the North American Arctic and Subarctic, but such issues arise in communities around the globe. Countries such as Kiribati and Maldives face inundation from sea level rise, possibly leaving residents stateless. Sea level rise and extreme weather threaten lives and livelihoods in coastal communities in Egypt, Panama, and elsewhere. Research must support and build the capacity of Indigenous Tribes and local communities so that they have tools to respond dynamically to support adaptation that protects their human rights.

How climate change may alter 10 of the world’s natural wonders

Natural wonders around the world may be altered forever — or even cease to exist — if global temperatures continue to rise.

Climate change is contributing to rising sea levels and more intense weather events, which will not only leave humans and landscapes vulnerable but also some of the world’s treasures as well.

Norway-based outdoor guide company Outforia used research and predictions from a plethora of published scientific papers to illustrate what could happen to 10 beloved landmarks if drastic measures are not soon taken to reduce greenhouse gas emissions.

The company chose which landmarks to feature based on sites that mean “a lot to a lot of different people,” Carl Borg, founder of Outforia, told ABC News.

The deterioration of any of the landmarks would be a “great loss,” both for humans who will no longer be able to experience the wonders and for the ecosystems and species that depend on the sites for survival, Borg said.

Here are the natural wonders that may be destroyed by climate change:

The Alps, mainland Europe

The Alps, the expansive mountain range that stretches across much of mainland Europe, may lose the glaciers and optimal ski conditions it is best known for if temperatures continue to rise.

The warming temperatures are affecting both the composition of the permafrost that holds the rocks together as well as the volume of the snow, according to the European Environmental Agency.

As the ice melts and falls, it creates a hazard for both locals and millions of tourists who visit the Alps annually, Fabrizio Troilo, a geologist for the Italian-based organization Safe Mountain Foundation, told ABC News in 2018 as glaciers atop Mont Blanc, located in the Alps between Italy and France, continued to melt in response to the warming Earth.

Glaciers in the European Alps could lose up to 90% of their ice by 2100 if greenhouse gas emissions continue as business as usual, a study published in 2019 in The Cryosphere, part of the European Geosciences Union, found.

Borg, who grew up skiing in the Alps, said the issue is “close” to him.

“It’s really one destination that will see severe change,” he said.

The North Pole

Sea ice in the Arctic could disappear altogether by 2035 due to warming climates, which could potentially impact both organisms living in the North Pole and humans living thousands of miles away, according to a 2020 study published in Nature Climate Change.

In 2019, the Greenland Ice Sheet lost a record 1 million metric tons per minute, amounting to nearly 600 billion tons, according to a study published in Communications Earth & Environment based off NASA satellite imagery.

Polar sea ice helps to regulate Earth’s climate by reflecting the sun’s energy back into space, rather than allowing the dark seawater to absorb the radiation and make the global climate even warmer.

In addition, animals such as polar bears, which hunt seals from the ice, depend on it. Polar bears were added to the list of protected species under the Endangered Species Act in 2008 due to the melting of their habitat.

“That’s 14 years from now, where the North Pole will only be reachable by boat for the first time in human history,” Borg said.

The Everglades, Florida

Rising sea levels could potentially drown the Everglades, the expansive tropical wetlands located in South Florida, in saltwater.

Due to a combination of melting glaciers and ice sheets, as well as thermal expansion of seawater as it warms, sea levels have already risen about 8 to 9 inches since the 19th century, with about a third of that coming in just the last 5 years, according to the National Oceanic and Atmospheric Administration.

Global sea levels will likely rise at least another 12 inches by 2100 according to the latest models, “even if greenhouse gas emissions follow a relatively low pathway in coming decades,” according to NOAA.

With Florida’s flat topography, the state is especially vulnerable to sea level rise, Jayantha Obeysekera, director of the Sea Level Solutions Center, told ABC News. The effects of climate change are already being seen in urban areas such as Miami Beach, where “sunny day” flooding, which takes place in the absence of rain, is already happening during high tides, Obeysekera said.

As the ocean water comes in, the elevation in the Everglades is in danger of collapsing as the ocean water interacts with the natural ecosystem’s swamp water, Obeysekera said.

The influx of salt will also not be conducive to maintaining the sensitive ecosystem of the Everglades, which is integral in housing mangroves and other vegetation in the region, Obeysekera said.

Victoria Falls, Zambia & Zimbabwe

Victoria Falls, the waterfall on the Zambezi River in Africa, where water gushes more than 300 feet below, could dry up as a result of climate change.

In 2019, the falls slowed to a trickle after the worst drought in the region in a century.

The event, which included the lowest water flow since 1995, was described as “a stark reminder of what climate change is doing to our environment.”

As severe droughts increase in the region as a result of climate change, scientists fear that the falls could potentially dry up for good, Borg said.

The absence of the Victoria Falls could also kill the tourism industry in the region, which welcomes millions of visitors each year.

Borg noted the illustration Outforia rendered for the Victoria Falls as having one of the starkest differences between the before and after shots, especially since the “after” illustration was based off the image taken amid the 2019 drought, he said.

Great Salt Lake, Utah

The Great Salt Lake, the eight-largest terminal lake in the world and the largest saltwater lake, is losing its volume at alarming rates, and climate change is partly to blame.

As of 2017, the lake had lost half of its water since the first settlers, Mormon pioneers, arrived in 1847, according to a study published in Nature Geoscience.

Most of the decline was attributed to modern civilization, as humans continue to take water out of rivers and streams that once fed the lake to be used in homes, farms and industries. But, weather and climate change are responsible for the drop as well.

The demise of the Great Salt Lake would spell trouble for the environment, as well as the biodiversity in the region, according to a recent study published last year in Springer Nature.

If the lake were to dry out, dust storms would be a great concern due to the decades of heavy metals and toxic substances that remain trapped in the sediment. In addition, bird populations would suffer. The brine shrimp that is harvested from the lake and sold as food would disappear. Industries that extract minerals from the lake for fertilizers and lightweight metals would likely close — shuttering an industry worth $1.3 billion, The Salt Lake Tribune reported.

Joshua Tree National Park, California

The iconic Joshua trees of Southern California could disappear as a result of warming temperatures.

Scientists predict that Joshua Tree National Park, nestled near the Colorado Desert and the Mojave Desert, will lose almost all of its Joshua trees by 2070, when the suitable habitat is predicted to be whittled down to just .02% of current levels, according to a 2019 study published in Ecosphere.

Severe drought may cause species like the Joshua tree, desert tortoise and desert bighorn sheep to seek higher elevations that receive more rainfall, according to the National Park Service.

Not only is the health of the yucca moths, which the Joshua trees rely on to reproduce, in peril, but the trees face increased danger of rampaging wildfires in the west, according to the study.

“They are really the sort of the most common and distinctive feature of this desert and a very important part of the ecosystem,” Borg said, lamenting the potential loss of the species. “They are providing food and shelter for all sorts of different creatures.”

Saguaro National Park, Arizona

The saguaro cactus, known for its distinctive shape and cultural significance as an emblem of the landscape in the southwestern U.S., has been on the decline for years due to climate change, according to a 2018 report by the National Park Service.

Drought, as well as invasive plants such as buffelgrass and stinknet that cover the desert floor, have left the cacti susceptible to fast-spreading wildfires.

But once the cacti melt away, it does not grow back. The plants need “very specific conditions” to reproduce and replenish their population, and highly variable or extreme weather makes it difficult for the saguaro to thrive, according to the National Park Service.

The saguaro cactus has been living in the region for more than 5,000 years, Borg said.

The number of saguaros surviving in Saguaro National Park in Pima County, Arizona, has been on the decline for decades, according to the NPS. The number of young saguaros surviving in the park has been low since the mid-1990s due to drought.

Low winter temperatures in the region have risen 10 to 15 degrees in the last century, according to the NPS.

Great Barrier Reef, Australia

The underwater ecosystem in the Great Barrier Reef, the largest living structure in the world, is at risk of losing both its coral and the organisms it houses.

As the climate warms, coral bleaching occurs. When the water is too warm, the algae the corals expel from their tissues cause them to turn completely white.

The Great Barrier Reef has lost half of its coral since 1995, a study published last year in the Proceedings of the Royal Society B found.

Coral reefs will stop growing in the next decade or so unless a significant reduction in greenhouse gases is achieved, a new study published last month in the Proceedings of the National Academy of Sciences suggests.

The research highlights a “grim picture” for the future of coral reefs, Christopher Cornwall, a marine botanist at the Victoria University of Wellington in Australia, told ABC News via email.

The conservation status for the reef declined to “critical” levels in 2020 due to increasing impacts associated with climate change, according to the International Union for Conservation of Nature’s 2020 World Heritage Outlook report.

“The only hope for coral reef ecosystems to remain as close as possible to what they are now is to quickly and drastically reduce our CO2 emissions,” Cornwall said. “If not, they will be dramatically altered and cease their ecological benefits as hotspots of biodiversity, sources of food and tourism, and their provision of shoreline protection.”

The decline of the coral has also resulted in decreasing populations of certain marine species, researchers found. The reef houses more than 1,500 species of fish.

In addition, should sea levels continue to rise due to climate change, reefs will no longer be effective at protecting coastlines because the production will not be able to keep up with the amount of melting ice, Cornwall said.

White Cliffs of Dover, United Kingdom

The White Cliffs of Dover, the region of English coastline facing the Strait of Dover and France, could eventually fade away as rising sea levels and stronger storms with fiercer waves batter the cliffs, eventually shrinking them to a fraction of the current size.

The cliffs are a historic symbol of the southern coast of the United Kingdom but have been eroding at a rate up to 10 times faster than the past several thousand years, scientists say.

Over most of the past 7,000 years, the erosion rate of the cliffs was about two centimeters a year, according to a 2016 study published in the Proceedings of the National Academy of Sciences. Over the past 150 years, the erosion rate has been between 22 and 32 centimeters a year, researchers said.

The increase has been as a result of climate change and human interference, as the sand and gravel has been shifted to protect specific beaches, according to the study.

Glacier National Park, Montana

Glacier National Park is warming at nearly two times the global average, which is already shrinking glaciers and increasing wildfires, according to the National Park Service.

The park’s glaciers, the main attraction for hikers and backpackers, have been naturally cycling through periods of advance and retreat for thousands of years, but the current retreat began soon after the peak in 1850, when the warming trend began, according to NPS.

Just 26 of the parks original 150 glaciers remained as of 2015, and all the glaciers could potentially be lost within decades, according to a report by the U.S. Geological Survey.

“This is just one sort of place where what is happening, but really is part of a bigger pattern that is really affecting a lot of different glaciers worldwide,” Borg said.

How Returning Lands to Native Tribes Is Helping Protect Nature

From California to Maine, land is being given back to Native American tribes who are committing to managing it for conservation. Some tribes are using traditional knowledge, from how to support wildlife to the use of prescribed fires, to protect their ancestral grounds.

BY JIM ROBBINS • JUNE 3, 2021

n 1908 the U.S. government seized some 18,000 acres of land from the Confederated Salish and Kootenai Tribes to create the National Bison Range in the heart of their reservation in the mountain-ringed Mission Valley of western Montana.

While the goal of protecting the remnants of America’s once-plentiful bison was worthy, for the last century the federal facility has been a symbol to the tribes here of the injustices forced upon them by the government, and they have long fought to get the bison range returned.

Last December their patience paid off: President Donald Trump signed legislation that began the process of returning the range to the Salish and Kootenai.

Now the tribes are managing the range’s bison and are also helping, through co-management, to manage bison that leave Yellowstone National Park to graze on U.S. Forest Service land. Their Native American management approach is steeped in the close, almost familial, relationship with the animal that once provided food, clothes, shelter — virtually everything their people needed.

“We treat the buffalo with less stress, and handle them with more respect,” said Tom McDonald, Fish and Wildlife Division Manager for the tribes and a tribal member. The tribes, he noted, recognize the importance of bison family groups and have allowed them to stay together. “That was a paradigm shift from what we call the ranching rodeo type mentality here, where they were storming the buffalo and stampeding animals. It was really kind of a violent, stressful affair.”

In California, a land trust recently transferred 1,199 acres of redwood forest and prairie to the Esselen tribe.

There is a burgeoning movement these days to repatriate some culturally and ecologically important lands back to their former owners, the Indigenous people and local communities who once lived there, and to otherwise accommodate their perspective and participation in the management of the land and its wildlife and plants.

Throughout the United States, land has been or is being transferred to tribes or is being co-managed with their help. In California, a land trust recently transferred 1,199 acres of redwood forest and prairie to the Esselen tribe, and in Maine, the Five Tribes of the Wabanaki Confederacy recently reacquired a 150-acre island with the help of land trusts. Other recent land transfers to tribes with the goal of conservation have taken place in Oregon, New York and other states.

The use of Indigenous management styles that evolved over many centuries of cultures immersed in nature — formally called Traditional Ecological Knowledge (TEK) — is increasingly seen by conservationists as synergistic with the global campaign to protect biodiversity and to manage nature in a way that hedges against climate change.

The Nature Conservancy, for example, one of the world’s largest conservation organizations, has institutionalized the transfer of ecologically important land with its Indigenous Peoples and Local Communities Program in both the U.S. and globally.

“If you look at it from a land justice perspective, we need to support a strengthening and healing of that relationship,” said Erin Myers Madeira, director of Indigenous Peoples and Local Communities program for the Nature Conservancy. “If you look at it practically, Indigenous people are the original stewards of all the lands and waters in North America, and there’s an extensive knowledge and management practices that date back millennia.”

One of the largest completed land transfers began eight years ago in Australia when the federal and state governments bought 19 separate farm properties and the associated water rights for $180 million in the Lower Murrumbidgee Valley in New South Wales. The goal was to restore the vast and fertile wetlands — rich with birds, fish and other species — that had been damaged by wholesale water diversion for agriculture.

Interested parties were invited to submit proposals for the management of what was then called the Nimmie-Caira wetlands. A consortium that included the Nature Conservancy and the tribal council of the Nari Nari, the Indigenous people who have inhabited the region for 50,000 years, won the right to manage the property.

It is hard for outsiders to fathom how differently Indigenous cultures perceive the landscape and wild creatures.

The old irrigation infrastructure was removed and altered to return to a more natural and traditional water regime. In 2018, the first water using the wilder approach began flowing, and species such as golden perch and southern bell frogs, along with spoonbills, egrets, black swans and other birds, grew more abundant. The Nari Nari found and protected ancestral burial grounds, ancient clay ovens and other cultural sites, and hunted out thousands of invasive species , including feral pigs, deer, foxes and cats.

In 2019 the Nature Conservancy transferred the more than 200,000 acres of the Nimmie-Caira property to the sole ownership of the Nari Nari, who now manage it. The Nari Nari have renamed it Gayini, which means ‘water’ in their language.

“This is a significant event for the Nari Nari people, who have been using traditional knowledge to sustain our country for thousands of years,” said Nari Nari Tribal Chairman Ian Woods. “We can continue to protect the environment, preserve the Aboriginal heritage of the land and enable the intergenerational transfer of knowledge of caring for country.”

It’s hard for outsiders to fathom how differently many Indigenous cultures perceive the landscape and wild creatures, and their relationship to it, but it is clear their lives have been deeply intertwined with the natural world in a very different way than non-Indigenous cultures.

In a recent report, two U.S. Forest Service researchers, David Flores and Gregory Russell, offered an explanation of the difference between European and Indigenous concepts of nature. Indigenous holistic knowledge “regards animals and features of the landscape as possessing characteristics that Western minds typically ascribe only to humans, e.g. having points of view, exhibiting agency, and engaging in reciprocal communication.”

That fits with a description of the Salish Kootenai perspective on bison. “Buffalo power, being considered supernatural, was appealed to for the healing of the sick, for protection from enemies, and for prophecies regarding the welfare of the individual petitioner and the destiny of the tribal group…” wrote Henry Burland in 1941, as part of the Montana Writer’s Project. “Their myths reveal a close intimacy between Indian and buffalo.”

Because of this relationship and kinship with other species, as well as the land itself, new management policies and major changes among the Salish and Kootenai require that resource managers consult with tribal elders to maintain a close cultural connection with the bison.

President Biden has pledged to work with Native tribes as he moves to protect more public land.

That includes the traditional use of fire to manage the buffalo and the landscape. “The green-up after a burn is a huge attraction to buffalo,” said McDonald. “They can smell that succulent one inch of green that comes up in the black ground after a fire. Burning maintained hunting grounds and strong game populations like a farmer or rancher would do.”

The traditional use of fire may be the most talked-about topic involving traditional ecological knowledge these days, because of the catastrophic fires that have swept the American West. In addition to using “fire as medicine” to manage wildlife habitat and forests to increase ecological resilience or to grow certain useful species for such things as basket making or food, traditional planned burning has important applications to reduce the intensity of conflagrations. A recent study found that the Indigenous fire regime in the forest around the Jemez Pueblo in New Mexico — primarily perennial small fires and wood gathering in settled areas — “made the landscape resistant to extreme fire behavior.”

The model has implications for managing fires in the wildlands-urban interface across the Western United States, where homes and forests are intermingled.

The trend of increasing aboriginal management is not just about providing title to new land. The Obama Administration envisioned that Bear’s Ears National Monument in Utah, filled with sacred and other Native cultural sites, would be co-managed by the Department of Interior and a five-tribe coalition. And last fall, a report was published by Martin Nie and Monte Mills, professors of natural resource policy and Indian law respectively at the University of Montana — though acting as private individuals — on the steps needed to overcome barriers and increase co-management of America’s public lands with tribes, especially changes in federal law that would require agencies to work with tribes on a co-management basis.

For the first time since 1770, members of the Esselen tribe hold a ceremony on ancestral land returned to them in California’s Big Sur region. MATTHEW PENDERGAST

Now, with Native American Deb Haaland at the helm of the Interior Department, the movement toward co-management of public lands with the tribes, if not outright transfer, is expected to gain steam. President Biden has pledged to listen to and work with Native tribes in the West as he moves to protect more public land and, especially, as he moves to fulfill his promise to protect 30 percent of the U.S. by 2030, the 30×30 plan.

Other countries have adopted similar projects. In Canada for example, the federal government partnered with the Qikiqtani Inuit Association to co-manage the Tallurutiup Imanga National Marine Conservation Area & Tuvaijuittuq Marine Protected Area in the Nunavut Territory, which encompasses much of Canada’s northern region. The native name “Tuvaijuittuq” means “the last ice area,” and it is the place where the ice that now remains in the Arctic is the thickest and is likely to last the longest in the face of climate change. It could well become the last refuge for polar bears, seals, narwhal, walrus and beluga, as well as the algae beneath the ice that is the bottom of the Arctic food chain. It could be the last refuge, too, for subsistence hunters as the climate warms.

Local land trusts are also moving toward the return of land. In addition to the Nature Conservancy, which has perhaps a dozen projects in the U.S., some local efforts are seeking this kind of redress. First Light is an effort by dozens of land trusts and five tribes of the Wabanaki Confederacy tribes, to have access to ancestral lands throughout Maine for hunting, gathering and ceremonial purposes. It includes a 150-acre island that the Passamaquoddy called Pine Island, which was taken from them by European settlers. And last month, the New York-based Open Space Institute transferred 156 acres along the Hudson River to the Mohican Nation Stockbridge-Munsee Band, which will manage it as a nature preserve.

Much of the campaign to return Indian land is part of the racial justice movement that is sweeping the globe.

The Esselen Tribe of California, which had inhabited the Big Sur region for thousands of years, was stripped of its culture and lands by the Spanish, who built missions in the region. The Western Rivers Conservancy, with funding from the California Natural Resources Agency, arranged the purchase of a 1,199-acre ranch with redwood forest and a crystalline stream, the Little Sur, where steelhead spawn, to protect it and planned to donate it to the U.S. Forest Service. Locals objected, and so last year they instead transferred the property, valued at $4.5 million, to the Esselen – 250 years after it was taken. The tribe says it will protect natural values, including spawning steelhead, the California spotted owl, the endangered Calfiornia condor and habitat that connects the ocean to the Santa Lucia Mountains, as well as use the land for traditional ceremonies and plant gathering.

In many cases, tribes are buying land that is important to them. In Northern California, the Yurok Tribe, the largest tribe in California, owns 44 miles of land along the Klamath River. They have been piecing back their aboriginal lands, with the help of land conservation groups such as the Trust for Public Land and Western Rivers Conservancy, to protect the habitat of their primary food source, salmon, and to assure access to ceremonial grounds and other cultural landscapes. The Yurok have purchased more than 80,000 acres to add to their holdings, including 50,000 acres that had been been owned by a timber company and surround four salmon spawning streams that the tribe now plans to restore.

Much of the campaign to return Indian land or at least allow co-management is part of the racial justice movement that is sweeping the globe. In the American Indian community, it’s called #Landback — and some in that movement see a more radical form of reconciliation.

In a recent article in the Atlantic, David Treuer, a Native American, citing the litany of forced removal and broken treaties that enabled the creation of U.S. national parks, advocated for giving a consortium of Native American tribes the ownership and management responsibility — with binding covenants to protect natural values — for all 85 million acres of the national park system, as reparations in kind for land that was stolen from them.

“The total acreage would not quite make up for the General Allotment Act, which robbed us of 90 million acres, but it would ensure that we have unfettered access to our tribal homelands,” he wrote. “And it would restore dignity that was rightfully ours. To be entrusted with the stewardship of America’s most precious landscape would be a deeply meaningful form of restitution.”

Still, there are some concerns about possible downsides to tribal management. Will tribes allow hunting in places where it hasn’t been allowed because of tradition? Or will a change in tribal administrations alter policies toward ecologically important lands that no longer favor protection?

One three-nation study found Indigenous-managed lands were richer in vertebrate species than existing protected areas.

The Confederated Salish and Kootenai tribal management of natural resources has been highly praised. They created the nation’s first tribal wilderness area, the Mission Mountain Wilderness Area, and annually close off 10,000 acres of it to humans to allow grizzly bears — a spirit animal — to feed on a summer bonanza of lady bugs and army cutworm moths high in the mountains.

But there are numerous examples of natural resource exploitation by tribes as well, and some critics say problems could arise from Indigenous management.

After a decades-long fight to get oil and gas leases voided in the Badger-Two Medicine area along Montana’s wild Rocky Mountain Front, a bill was introduced in Congress to allow the Blackfeet to co-manage the Badger-Two Medicine, part of the Helena-Lewis and Clark National Forest, as a ‘cultural heritage area.’

George Wuerthner, the Oregon director of the Western Watersheds Project and a longtime public lands watchdog, observed in a recent blog post that the Blackfeet Reservation, near the Badger-Two Medicine, is far from an example of good conservation stewardship, with widespread leasing for oil and gas fracking, livestock overgrazing along many riparian areas, and poaching, including of grizzly bears.

“One hopes that if the tribe is given co-management of the area, they will treat these public lands better than they treat their reservation lands,” Wuerthner wrote. “However, the way to assure that this will happen is by designating the area a wilderness area. A ‘cultural heritage’ area is an untested designation and may not guarantee full protection of the landscape.”

Those who are working to get some conservation landscapes into the hands of Indigenous people say a growing number of studies have shown the efficacy of native management. For example, a study published last year by Richard Shuster and Ryan R. Germain of the University of British Columbia found that Indigenous-managed lands in Australia, Brazil and Canada were richer in vertebrate species than existing protected areas.

In some cases, proponents admit, there could be negative impacts for conservation goals if ecologically important landscapes are managed by Indigenous people. But, “when you look holistically, the benefits and the approaches Indigenous people have taken have been far and away better than many of the Western approaches,” said Brian O’Donnell, director of the Wyss Foundation’s Campaign for Nature. “Does that mean that universally every place will be conserved for biodiversity? No. But if we embrace and learn from an Indigenous world view on land and use that as a paradigm in which to set a lot of our future conservation approaches, I think we will be a whole lot better off than if we don’t.”

Correction, June 4, 2021: An earlier version of this article incorrectly identified the status of Badger-Two Medicine in Montana. It is not a federally protected Wilderness Area but is part of the Helena-Lewis and Clark National Forest.

Nature vs. Nurture: How Are Personalities Formed?

Is it Genetics or Environment and Experience That Make Us Who We Are?

By Kimberly PowellUpdated August 14, 2019

You got your green eyes from your mother and your freckles from your father—but where did you get your thrill-seeking personality and talent for singing? Did you learn these things from your parents or was it predetermined by your genes? While it’s clear that physical characteristics are hereditary, the genetic waters get a bit murkier when it comes to an individual’s behavior, intelligence, and personality. Ultimately, the old argument of nature versus nurture has never really had a clear winner. While we don’t really know how much of our personality is determined by our DNA and how much by our life experience, we do know that both play a part.https://96ecd31a83d45930c4d241f1c9628dc0.safeframe.googlesyndication.com/safeframe/1-0-38/html/container.html

The “Nature vs. Nurture” Debate

The use of the terms “nature” and “nurture” as convenient catch-phrases for the roles of heredity and environment in human development can be traced back to 13th-century France. In simplest terms, some scientists believe people behave as they do according to genetic predispositions or even “animal instincts,” which is known as the “nature” theory of human behavior, while others believe people think and behave in certain ways because they are taught to do so. This is known as the “nurture” theory of human behavior.https://96ecd31a83d45930c4d241f1c9628dc0.safeframe.googlesyndication.com/safeframe/1-0-38/html/container.html

Fast-growing understanding of the human genome has made it clear that both sides of the debate have merit. Nature endows us with inborn abilities and traits. Nurture takes these genetic tendencies and molds them as we learn and mature. End of story, right? Nope. The “nature vs. nurture” argument rages on as scientists debate how much of who we are is shaped by genetic factors and how much is a result of environmental factors.

The Nature Theory: Heredity

Scientists have known for years that traits such as eye color and hair color are determined by specific genes encoded in each human cell. The nature theory takes things a step further by suggesting that abstract traits such as intelligence, personality, aggression, and sexual orientation can also be encoded in an individual’s DNA. The search for “behavioral” genes is the source of constant dispute as some fear that genetic arguments will be used to excuse criminal acts or justify antisocial behavior.https://96ecd31a83d45930c4d241f1c9628dc0.safeframe.googlesyndication.com/safeframe/1-0-38/html/container.html

Perhaps the most controversial topic up for debate is whether or not there’s such a thing as a “gay gene.” Some argue that if such genetic coding does indeed exist, that would mean genes play at least some role in our sexual orientation.

In an April 1998 LIFE magazine article titled, “Were You Born That Way?” author George Howe Colt claimed that “new studies show it’s mostly in your genes.” However, the issue was far from settled. Critics pointed out that the studies on which the author and like-minded theorists based their findings used insufficient data and too narrow a definition of same-sex orientation. Later research, based on a more conclusive study of a broader population sample reached different conclusions, including a 2018 groundbreaking study (the largest of its kind do date) co-conducted by the Broad Institute in Cambridge, Massachusetts, and Harvard Medical School in Boston that looked at the possible links of DNA and homosexual behavior.

This study determined that there were four genetic variables located on chromosomes seven, 11, 12, and 15, that do seem to have some correlation in same-sex attraction (two of these factors are specific only to males). However, in an October 2018 interview with Science, the study’s chief author, Andrea Ganna, denied the existence of a “gay gene” per se, explaining: “Rather, ‘nonheterosexuality’ is in part influenced by many tiny genetic effects.” Ganna went to say that researchers had yet to establish the correlation between the variants they’d identified and actual genes. “It’s an intriguing signal. We know almost nothing about the genetics of sexual behavior, so anywhere is a good place to start,” he admitted, however, the final takeaway was that the four genetic variants could not be relied on as predictors of sexual orientation.https://96ecd31a83d45930c4d241f1c9628dc0.safeframe.googlesyndication.com/safeframe/1-0-38/html/container.html

The Nurture Theory: Environment

While not totally discounting that genetic tendency may exist, supporters of the nurture theory conclude that, ultimately, they don’t matter. They believe our behavioral traits are defined solely by the environmental factors that affect our upbringing. Studies on infant and child temperament have revealed the most compelling arguments for the nurture theory.

American psychologist John Watson, a strong proponent of environmental learning, demonstrated that the acquisition of a phobia could be explained by classical conditioning. While at Johns Hopkins University, Watson conducted a series of experiments on a nine-month-old orphaned infant named Albert. Using methods similar to those employed by Russian physiologist Ivan Pavlov with dogs, Watson conditioned the baby to make certain associations based on paired stimuli. Every time the child was given a certain object, it was accompanied by a loud, frightening noise. Eventually, the child learned to associate the object with fear, whether the noise was present or not. The results of Watson’s study were published in the February 1920 edition of the Journal of Experimental Psychology.

” Give me a dozen healthy infants, well-formed, and my own specified world to bring them up in and I’ll guarantee to take any one at random and train him to become any type of specialist I might select … regardless of his talents, penchants, tendencies, abilities, vocations and race of his ancestors.”

Harvard psychologist B. F. Skinner’s early experiments produced pigeons that could dance, do figure-eights, and play tennis. Today Skinner is known as the father of behavioral science. Skinner eventually went on to prove that human behavior could be conditioned in much the same way as animals.

Nature vs. Nurture in Twins

If genetics didn’t play a part in the development of our personalities, then it follows that fraternal twins reared under the same conditions would be alike regardless of differences in their genes. Studies show, however, that while fraternal twins do more closely resemble one another than non-twin siblings, they also exhibit striking similarities when reared apart from the twin sibling, much in the same way that identical twins raised separately often grow up with many (but not all) similar personality traits.

If the environment doesn’t play a part in determining an individual’s traits and behaviors, then identical twins should, theoretically, be the same in all respects, even if reared separately. However, while studies show that identical twins are never exactly alike, they are remarkably similar in most respects. That said, in “Happy Families: A Twin Study of Humour,” a 2000 study published by faculty at the Twin Research and Genetic Epidemiology Unit at St. Thomas’ Hospital in London, researchers concluded that a sense of humor is a learned trait influenced by family and cultural environment, rather than any genetic predetermination.

It’s Not “Versus,” It’s “And”

So, is the way we behave ingrained before we’re born, or does it develop over time in response to our experiences? Researchers on both sides of the “nature versus nurture” debate agree that the link between a gene and behavior is not the same as cause and effect. While a gene may increase the likelihood that you’ll behave in a particular way, it does not ultimately predetermine behavior. So, rather than being a case of “either/or,” it’s likely that whatever personality we develop is due to a combination of both nature and nurture.
