Global Amphibian Assessment revealed 99 amphibian species as adversely impacted by exploitation for international trade including 35 species that are globally threatened. Currently 36 of these species (16 of globally threatened species) are listed on CITES. Retaining viable populations in their native habitats is an essential conservation response for ensuring long term persistence of species.
