A biodiversity hotspot is a region of the earth that is extremely biologically diverse and also under severe threat due to habitat loss climate change or extensive species loss.

A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation. Biodiversity hotspots make up about 2 3 percent of earth s land surface but 44 percent of the world s plants and 35 percent of land vertebrates live in these regions. The hotspots are rich in floral wealth reptiles amphibians mammals and also in their endemism. There are currently 36 recognized biodiversity hotspots.
