Two of South America's most extraordinary ecosystems have just been connected by a thread of protected land that could help wildlife survive the century.
Ecuador has announced the creation of the **Llanganates–Yasuní Connectivity Corridor** — a 2,159-square-kilometre protected zone running between Llanganates National Park in the Andes and Yasuní Biosphere Reserve in the Amazon. The corridor, reported by Mongabay in March 2026, stitches together highland and lowland habitats across a landscape of forests, rivers, and farmland that had been fragmenting for decades.
For jaguars, giant otters, tapirs, harpy eagles, and hundreds of other species that move across large territories, it could make the difference between survival and local extinction.
**Why Corridors Matter**
A reserve with no connections to other reserves is an island. Like the islands Darwin studied, it will eventually lose species — through inbreeding, through local catastrophes with no recovery route, through the slow mathematics of small-population genetics. A connected landscape is different: animals can move, populations can mix, and when something goes wrong in one patch of forest, individuals can arrive from another.
The problem for South American wildlife is that the Andes-Amazon transition zone — one of the most biodiverse regions on Earth — has been heavily fragmented by decades of agricultural expansion, road building, and settlement. Large carnivores and migratory species that once moved freely between highland and lowland habitats were increasingly hemmed in by farms and fences.
The Llanganates–Yasuní Connectivity Corridor addresses this directly, establishing **"altitudinal connectivity"** — a protected pathway that runs from high Andean cloud forest down through the foothills and into the Amazon lowlands, allowing species to move across elevational gradients as they always have, and as climate change increasingly requires.
**What the Corridor Protects**
Llanganates National Park, at the corridor's western end, is a remote and largely unexplored Andean park covering almost 220,000 hectares of cloud forest, páramo grassland, and glacier-fed rivers. Its rugged terrain has limited human development and maintained extraordinary biodiversity, including threatened spectacled bears, Andean condors, and dozens of endemic plant species.
Yasuní Biosphere Reserve, at the eastern end, is one of the most biodiverse places on Earth. Its 9,800 square kilometres of Amazon rainforest contain more tree species per hectare than anywhere else in South America, and it is home to jaguars, giant river otters, river dolphins, and two of the last uncontacted indigenous peoples remaining in the world.
Between these two protected areas, the new 2,159 km² corridor now provides the linking habitat that allows wildlife to move between them — and allows the genetic diversity of both populations to intermingle.
**Jaguars: The Key Beneficiary**
The jaguar is perhaps the species that stands to gain most from landscape-level connectivity. As the Americas' apex predator, it requires vast territories — male jaguars may roam 50–100 km² or more — and plays a structuring ecological role across its entire range. Its presence in a landscape signals that the rest of the food web is intact.
Jaguars once ranged from the southern United States to Argentina. That range has shrunk dramatically, fragmented by agricultural expansion into isolated strongholds. Conservation organisations have spent years mapping jaguar corridors — landscape linkages that allow different populations to stay connected. The Llanganates–Yasuní Corridor adds a critical link in Ecuador's section of this continental network.
**A Model for Mountain-to-Rainforest Conservation**
The Andes-Amazon transition zone is one of global conservation's most significant frontiers. The extraordinary biodiversity of these regions — which together contain around 10% of all species on Earth — and their rapid deforestation rate make protecting and connecting them a conservation priority of the highest order.
Ecuador's announcement joins a growing set of regional commitments. Neighbouring Bolivia recently protected 907,000 hectares of Andes-Amazon transition forest. Brazil has been expanding Indigenous territories that function as de-facto conservation areas in the Amazon. The cumulative effect of these decisions is beginning to create — slowly, imperfectly, but meaningfully — a more connected web of protected habitats across one of the world's great biodiversity hotspots.
2,159 square kilometres is a beginning. In a region where survival is measured in connection, every thread counts. 🌿🐆
