In this study, we assessed the occurrence and densities of medium to large size forest-floor mammals and selected terrestrial bird species at Cocha Cashu Biological Station (CCBS), a highly protected and isolated site within Manu National Park, Peru. Using 82 camera traps deployed for 7,375 camera-trap days during the 2022 dry season, we recorded 50 species. We estimated population densities for 16 terrestrial mammal species using the Random Encounter Model (REM) method. For spotted felid species (Jaguar (Panthera onca), Ocelot (Leopardus pardalis), and Margay (Leopardus wiedii)), individuals were identified, allowing comparison between REM-derived density estimates and abundance estimates based on individual recognition. Several key species exhibited high densities relative to expectations for Amazonian lowland forests, indicating a well-preserved mammal community at CCBS. Our results suggest that the site’s long-term protection, remoteness, and absence of hunting have contributed to the maintenance of healthy wildlife populations, underscoring the importance of strictly protected areas for conserving Amazonian biodiversity.
