Amazon-based scientists have long known that rapidly rising temperatures mean that places where species live today won’t be where they live tomorrow. For a vast number of species — ranging from insects, birds and primates to all manner of plants — upslope migration could present a potential, though perilous, pathway to resilience and survival during the climate crisis. This knowledge has raised a vital question: What are the most likely and best protected routes by which species across the Amazon’s broad expanse can relocate upward, helping preserve biodiversity, and hopefully keeping intact the ecosystem services tropical forests now deliver? In what is deemed the first region-wide assessment of Amazonia’s climate resilience and connectivity, a new study points to the western part of the biome, particularly the Andean spine of Peru, as the most viable upslope corridors. According to researchers, this region has the highest concentration of key components needed to support species survival — including major elevation gradients, large established protected areas, and connected forested corridors to facilitate upslope species migration. The scientists pinpointed additional potential corridors in southwestern Colombia, northern Brazil, northern Bolivia, north-central Guyana, and western Suriname. But these areas are disadvantaged due to fewer protected areas, with connectivity in many locales broken by forest fragmentation due to deforestation and oil and gas drilling. Published in May in the journal Global Ecology and Conservation, the new study, titled “A regional-scale assessment of climate-resilient corridors and connectivity in the Amazon,” was undertaken with the goal of providing findings that…This article was originally published on Mongabay
