Centre of endemism

A Centre of Endemism is an area in which the ranges of restricted-range species overlap, or a localised area which has a high occurrence of endemics. Centres of endemism may overlap with biodiversity hotspots which are biogeographic regions characterized both by high levels of plant endemism "and by serious levels of habitat loss". The exact delineation of centres of endemism is difficult and some overlap with one another. Centres of endemism are high conservation priority areas.
Examples of Centres of Endemism.
