UNESCO designated sites in Latin America and the Caribbean harbour over 60% of the region’s mapped species richness, i.e. over 14,000 species of mammals, reptiles, amphibians, birds, and fishes. They are also important for strengthening culture and nature linkages. However, biodiversity in these sites is threatened by human pressures and climate change and countries should take urgent action to halt and reverse biodiversity loss.This publication provides a regional overview of the status and trends of species in UNESCO designated sites, as well as key information to facilitate dialogue among all stakeholders. Additionally, it promotes the development of effective actions aimed at achieving global biodiversity goals.
