A coalition of local conservationists, international philanthropists, and thousands of individual donors has permanently protected more than 328,000 acres of pristine wilderness in Chilean Patagonia — closing the door on industrial development and securing one of the least disturbed ecosystems on Earth. The Conserva Puchegüín coalition raised more than $78 million to purchase Fundo Puchegüín, a vast undeveloped property in the heart of the Cochamó district, ending years of uncertainty that began when the previous owner listed it for sale in 2022 C.E.
At a glance
- Patagonia conservation: The 328,351-acre Fundo Puchegüín purchase connects to a 4-million-acre network of protected land spanning Chile and Argentina.
- Funding and leadership: More than $78 million was raised by a coalition led by local NGO Puelo Patagonia, with support from The Nature Conservancy, Freyja Foundation, Patagonia Inc., and the Wyss Foundation.
- Protection model: At least 80% of the land will be under strict conservation; up to 20% is designated for sustainable uses including low-impact tourism and agriculture.
Why this land matters
Fundo Puchegüín is not simply a beautiful piece of wilderness — it is an ecological keystone. The property makes up a significant portion of the Puelo River watershed, providing clean water to communities and ecosystems far downstream. Its connected habitats — rivers, lakes, forests, and wetlands — function as carbon sinks, climate refuges, and corridors for wildlife movement across the southern Andes.
The land shelters several endangered and endemic species, including Darwin’s frog, the monito del monte, and the huemul deer, which appears on Chile’s national coat of arms. Ancient alerce trees — sometimes called the redwoods of the south, with some individuals living more than 3,000 years — stand among its old-growth forests. These trees store carbon accumulated over millennia and have been identified as a conservation priority by the Global Trees Campaign due to centuries of historical logging and their extremely slow regeneration.
Before this purchase, industrial threats including mining operations and hydroelectric proposals had long loomed over the valley. That uncertainty is now resolved.
A community-rooted model for conservation
What distinguishes this campaign is how it was achieved. Rather than a top-down government initiative, Conserva Puchegüín grew from deep local attachment to the land. Puelo Patagonia, the Chilean NGO that anchored the effort, had defended the Cochamó valley for decades before the fundraising campaign began.
“This is a historic milestone not only because of the size of the protected area, but also because of how it was achieved: with participation, transparency, and deep respect for the communities that live in Cochamó,” said Andrés Diez, executive director of Puelo Patagonia.
The coalition created the Conserva Puchegüín Foundation — a Chilean non-profit — as the new legal owner of the land. Its independent board of directors is responsible for upholding founding principles: protecting the nature and culture of the area, and ensuring local communities have genuine participation in management decisions. The governance structure reflects a broader international trend that the International Union for Conservation of Nature has documented: privately managed protected areas, when properly governed, achieve conservation outcomes comparable to state-run parks.
The project also builds on a model pioneered by Tompkins Conservation, which assembled millions of acres of private protected land across Patagonia over three decades. Fundo Puchegüín now connects that broader network, creating an unbroken corridor of protected wilderness across the southern Andes.
Wildlife, water, and what comes next
With ownership now registered, the coalition will shift focus to implementing its governance and management framework. Wildlife and forest monitoring programs already launched during the acquisition process will continue, alongside tourism-management initiatives designed to benefit local residents rather than displace them.
The most ecologically sensitive portions of the property are envisioned as a future national park under new Chilean legislation for protected areas, while zones already used by local communities and visitors will allow sustainable activity to continue. The Wildlife Conservation Society Chile has worked for years to study and support huemul populations in this region; the large contiguous territory now gives the species room to move, breed, and recover.
Climate change is already altering precipitation and glacier melt across Patagonia. Intact watersheds like the Puelo River system become more ecologically valuable — and more critical for downstream communities — with every passing year. Protecting the headwaters now is an act of long-term thinking that benefits people as much as wildlife.
There are still open questions. Long-term funding for management and stewardship at this scale is a persistent challenge for private conservation efforts globally, and governance models that center local communities require sustained commitment to remain genuine rather than symbolic. The Conserva Puchegüín Foundation will face real tests as those challenges emerge.
But the purchase itself represents something rare: a community-rooted effort that mobilized thousands of people across Chile and around the world to protect a place they had never visited — because they understood it mattered. As The Nature Conservancy’s Global Managing Director Jeffrey Parrish put it, “This radical collaboration of passionate individuals and organizations large and small has come together to do something extraordinary — a real gift to our Earth and our grandchildren.”

COP30 pledges recognition of 160 million hectares of Indigenous land rights
At the COP30 World Leaders Summit in Belém, Brazil in November 2025, 15 governments pledged to formally recognize Indigenous land rights over 160 million hectares by 2030 — an area the size of Iran — through the Intergovernmental Land Tenure Commitment. Brazil committed at least 59 million hectares. More than 35 donors renewed a $1.8 billion Forest and Land Tenure Pledge. The Tropical Forest Forever Facility secured nearly $7 billion, with 20% directed to Indigenous peoples. It was the largest Indigenous participation in COP history.

Ghana declares its first marine protected area to rescue depleted fish stocks
Ghana’s marine protected area — the country’s first ever — marks a historic turning point for a nation gripped by a quiet fisheries crisis. Established near Cape Three Points in the Western Region, the protected zone restricts or bans fishing activity to allow severely depleted fish populations to recover. Ghana’s coastal stocks have fallen by an estimated 80 percent from historic levels, threatening food security and the livelihoods of millions of small-scale fishers. The declaration also carries regional significance, potentially inspiring neighboring Gulf of Guinea nations to establish coordinated protections of their own.

U.S. researchers cut Alzheimer’s risk by half in first-ever prevention trial
Alzheimer’s prevention may have reached a turning point after a landmark trial showed that removing amyloid plaques before symptoms appear can cut the risk of developing the disease by roughly 50%. Researchers at Washington University School of Medicine studied people with rare genetic mutations that make Alzheimer’s nearly inevitable, finding that early, aggressive treatment can genuinely alter the disease’s course. The results, published in The Lancet Neurology, mark the first time any intervention has shown potential to prevent Alzheimer’s from appearing at all, not merely slow its progression. That distinction matters enormously, since amyloid begins accumulating in the brain two…
