Despite thousands of hectares of reforestation in Costa Rica, the landscape across the country remains fragmented by patches of large-scale commercial plantations and human communities. These patchy areas have a lack of suitable habitat and prey, meaning there is very little gene flow within meta populations of many mammal & predator species. This study aims to establish a baseline for mammal presence and diversity in the Las Tablas protected zone in order to better inform conservation and habitat restoration efforts. In a camera trap study conducted from January 2023 - May 2023, 37 non-baited cameras were placed across a study area of 328 square kilometers. Sites were selected using a stratified study design, with cameras deployed in forest, farm, and fragment habitat. A total of 839 independent videos captured 29 species of mammals and large-bodied ground birds from 10 different taxa. Videos were analyzed using the Sanderson Method (Harris et al. 2010), for relative abundance, naive occupancy, and absence-presence matrices. White-nosed coati (Nasua narica) had both the highest relative abundance and naive occupancy. Pearson’s correlation used to analyze the relationship between species richness at a site against camera effort as well as different landscape covariates (distance to national park border, distance to a riparian corridor, and patch size) showed effort and patch size to be the strongest predictor of a site’s richness. Shannon-weiner alpha diversity indices were calculated for the three different landscape types. Forest land types had the highest diversity indices while fragments had the lowest. This research provides a comprehensive baseline for mammal presence and diversity to better inform habitat restoration and jaguar conservation efforts in the Las Tablas region.
