The Cauca Valley dry forests is a tropical dry broadleaf forest ecoregion in Colombia.

Location

The Cauca Valley dry forests occupies an area of 7,300 square kilometers (2,800 sq mi), extending in a long, narrow strip along the Cauca River. The Cauca Valley is nestled between the Cordillera Occidental and Cordillera Central in the northern Andes. These ranges create a rain shadow, which makes the Cauca Valley drier than the surrounding forests. The Cauca Valley dry forests lie below 1000 meters elevation; the higher slopes are occupied by the distinct Cauca Valley montane forests. Most of these forests have been cleared for agriculture over the years making it one of the most critically endangered ecoregions in Colombia. Laguna de Sonso Nature Reserve has a small area of protected forest.

Ecology

The ecoregion is part of the 103,000 square kilometres (40,000 sq mi) Tumbesian-Andean Valleys Dry Forests global ecoregion, which holds six terrestrial ecoregions: Tumbes–Piura dry forests, Ecuadorian dry forests, Patía Valley dry forests, Magdalena Valley dry forests, Cauca Valley dry forests and Marañón dry forests. The fauna and flora of the global ecoregion have high levels of endemism.^[1]

Human use

The Cauca Valley dry forests have been mostly converted to agricultural fields. The city of Cali lies in the ecoregion.
