Objetive : Determine the diversity and conservation status of land mammals of the municipality of San Vicente del Caguan, Caqueta, Colombia. Methodology : The research was conducted in 4 vegetation patches of characterized by high dense forest od solid land, gallery forest, secondary vegetation and weedy grasses surrounded by clean pasture. Visual sampling technique was used in day runs for recording arboreal mam- mals and ightless; for bats catching 4 mist nets were installed in each patch by ad libitum way, between 17:30 to 23:00. The obtained information was analyzed by an accumulation curve, Margaleft s diversity index, Shanon H, Simpson, Dominance and evenness, similarity and correspondence analysis. Results : 105 individuals of mammals, distributed in eight orders, 15 families and 23 species were recorded. the greatest diversity (H) and richest (M) was founded in high dense forest of solid land patches surrounded by grasses and secondary vegetation and greater evenness in Gallery Forest surrounded by clean pastu- re. Three species of special interest for conservation were identi ed, Tapirus terrestris , Ateles belzebuth y Lagothrix lagothricha. Conclusions : The study area is a place of high mammals diversity, with forest remaining shelter which are important areas for mammals. It is so important to make conservation initia- tives, because stress conditions (hunting, wood and oil extraction) are dangerous for the maintenance of this community in the department of Caqueta.
