An endemic species is a taxonomic unit whose natural distribution is restricted to a defined geographic area, such as a specific island, mountain range, ecoregion, or political region, and does not occur naturally elsewhere. In biogeography and conservation biology, endemism is used to quantify spatial patterns of biodiversity, identify centers of diversification, and prioritize regions for protection. Endemic species often exhibit high levels of local adaptation and evolutionary distinctiveness but are also disproportionately vulnerable to habitat alteration, invasive species, climate change, and other anthropogenic pressures due to their limited range and frequently small, fragmented populations.
