Mamíferos medianos y grandes del Espacio Territorial de Capacitación y Reincorporación (ETCR) Playa Rica, La Macarena, Meta, Colombia

The Yari savannas are an important biogeographic area whose biodiversity has not been explored. This area was historically under the control of illegal armed groups who restricted their access and investigation. With the peace process, the Yari savannas were opened to research, but also to anthropic processes that threaten their biodiversity. Here, we present a preliminary list that includes the first records of medium and large mammals from the northwestern sector of the Yari savannas, as a result of a community monitoring program with former FARC combatants. We report 24 species belonging to 18 families and 8 orders of mammals. We highlight the presence of ten threatened species including Priodontes maximus, Tapirus terrestris and Ateles belzebuth. This represents 96% of the land mammals in the Yari River. Based on the semi-structured interviews and field notes, we consider deforestation, the advance of the agricultural frontier, livestock and hunting as the main threats to mammals.
