Rabbits Pikas and Hares: Lagomorpha

Conservation Status

Six species of lagomorphs are listed by the World Conservation Union (IUCN) as Critically Endangered, facing an extremely high risk of extinction. Twelve species are listed as Endangered, facing a very high risk of extinction; fourteen species are listed as Vulnerable, facing a high risk of extinction; and one species, the Sardinian pika is listed as Extinct, died out. Eight species are listed as Near Threatened, not currently threatened, but could become so.

The primary reason for declining populations of lagomorphs are loss of habitat, disease, especially the pox virus myxomatosis (mix-oh-mah-TOE-sus), and conversion of habitats to agricultural use by humans.
