This camera survey had two objectives: To inventory medium to large-sized mammal species in a previously unstudied region of the Peruvian Amazon, and to investigate the impact of oil exploration on carnivore movement and activity, with a particular focus on the ocelot (Leopardus pardalis). The project was run by the Center for Conservation Education and Sustainability, Smithsonian Conservation Biology Institute.
The study took place in April to September 2008 at the Arabela River, Peru. Reconyx RC55 camera models were used at 23 stations for a sample period of 5 months, totaling 3285 camera nights. Cameras were placed on a system of trails that were opened specifically for the project. Cameras were placed, wherever possible, where they would intersect with existing game trails. The 23 stations were oriented in a grid, and formed a polygon of 22 km2. Adjacent stations were separated by an average of 1122 m (range = 1022–1371 m, SD = 86 m). Cameras were always in pairs. Scent lures were used at all stations initially, but were ineffective and soon removed.
