Central Colombia’s Magdalena Valley is one of the most biodiverse places on Earth. Centered around the 700-mile Magdalena River, this lowland rainforest is a biological melting pot with flora and fauna from both the Amazon and the Chocó.
But the valley also has astounding levels of endemism, a result of its relative isolation. The Magdelena rainforest provides vital habitat for many threatened species that live nowhere else, like the Critically Endangered Blue-billed Curassow and the Magdalena Spider Monkey. Researchers consider the latter to be one of Earth’s rarest primates. The area is also home to populations of the Jaguar, Spectacled Bear and Magdalena Lowland Tapir (a Critically Endangered subspecies).
