This study will evaluate mammals' distribution, diversity and population in a fragmented rainforest landscape in Costa Rica. It will determine how do the mammals react to the diverse landscape variables as patch form (perimeter-area relation), patch edge (area-perimeter relation), patch size, type of agricultural or cattle matrix, connectivity, forest coverage and habitat type. In order to make this study, a 100 km2 piece of land will be used. Inside this area, six different habitats will be located, and our sample will be eight 1-hectare-lots per habitat selected at random. The techniques for sampling mammals will be live (Sherman) traps, footprint and direct observation by transects, and footprints traps with smelling equidistant stations.

Our project will not be limited to the landscape physical-biological study but will also collect information about the local farmer’s perceptions and usage of the mammals, since their understanding is essential to plan efficient solution in the long term. Both biological and social components will be used to provide an adequate list of recommendations for the farming landscapes handling focusing on the mammal’s conservation.
