A new study has produced the first ever map of climate-resilient upslope corridors in the Amazon rainforest. These are routes that could allow plants and animals to escape rising temperatures by moving to higher, cooler ground. The map covers the entire Amazon basin across nine countries, with a focus on the Andean slopes where elevation changes fastest.
Where the escape routes run
The corridors follow natural features like ridgelines and river valleys that connect lowland forests to montane habitats. Researchers identified 227 potential corridors, each at least 200 meters wide. The study was led by scientists from Brazil’s National Institute for Amazonian Research and the University of Exeter in the United Kingdom. They used satellite data and climate models to predict where species would need to move as the planet warms.
Why local communities and conservationists took notice
For people living in the Amazon, these corridors are not just abstract lines on a map. Indigenous territories and protected areas overlap with many of the routes. In Brazil, Peru, Ecuador, and Colombia, local groups have long observed shifts in animal behavior and plant die offs. The map gives them a tool to prioritize which forests to keep connected. Without these pathways, species like the harpy eagle and the lowland tapir could become trapped in warming lowlands with no way out.
What the map actually shows
The study found that only 27 percent of the identified corridors are fully protected by existing reserves or Indigenous lands. The rest cross areas that are logged, farmed, or slated for development. The researchers stress that protecting these routes does not require moving people or creating new parks everywhere. It means keeping forest cover intact along the corridors so that animals and seeds can travel naturally. In some places, that might mean restoring a narrow strip of trees between two forest fragments.
A quiet tool for a fast moving problem
The Amazon is warming faster than the global average. Species that cannot adapt quickly enough must relocate or face local extinction. The upslope corridors offer a rare piece of good news: a practical, map based guide for where conservation efforts could have the biggest impact. The study does not prescribe solutions. It simply shows where nature is already trying to go.
