The pygmy hippopotamus, Choeropsis liberiensis is a shy inhabitant of the Upper Guinea Forest ecosystem of Liberia, Sierra Leone, Guinea and Côte d’Ivoire. With only about 2000-3000 individuals remaining, the pygmy hippo is classified as Endangered on the 2010 IUCN Red List, as well as being an Evolutionarily Distinct Species.
To prevent these enigmatic animals going extinct, ZSL has been working with partners in Liberia and Sierra Leone, carryimg out research to understand more about this species and establishing monitoring programmes using camera traps. We also led the production of the IUCN Pygmy Hippo Conservation Strategy in 2010.
Protecting Pygmy hippos
ZSL's EDGE of Existence Programme has prioritised pygmy hippos since 2007. We have worked to conserve them in Sapo National Park, Liberia (with Fauna and Flora International) and in the Loma Mountains, Sierra Leone (with Njala University). Our camera traps captured some of first wild photos of this incredible species.

Support Our Work
With fewer than 3000 individual pygmy hippos remaining in increasingly isolated populations, the need for conservation action for pygmy hippos has never been more urgent.
