In 2004 the International Union for Conservation of Nature and Natural Resource (IUCN) SSC Hippo Specialist Subgroup estimated that there were only 2-3,000 remaining pygmy hippos in the wild. They advocate protection of habitation through the extension of protected areas and legal enforcement against hunting and logging.
Since 2007 the Evolutionary Distinct and Globally Endangered (EDGE) team at the Zoological Society of London (ZSL) have been supporting bio-monitoring within Sapo National Park, in conjunction with Fauna and Flora International (FFI) and the Forest Development Authority (FDA). The most recent dedicated research was lead by ZSL in 2010 in Monrovia. Up to date maps and threat assessments were evaluated and a conservation strategy proposed. This includes a framework for realistic and long-term actions for pygmy hippo protection through continued research with strong government support.
Previous conservation efforts have until recently focussed monitoring bio-diversity within the rich area of Sapo National Park. Enfocring the boundaries and laws of Sapo National Park falls to the Forestry Development Authority (FDA) and although human settlement is prohibited within Sapo, hunting, poaching and logging continue to compromise natural habitat of pygmy hippos.
