dc.description.abstract | In order to explore the importance of indigenous agroforestry systems for biodiversity
conservation, we compared the abundance, species richness and diversity of dung beetles and
terrestrial mammals across a gradient of different land use types from agricultural monocultures
(plantains) to agroforestry systems (cocoa and banana) and forests in the BriBri and Cabe´car
indigenous reserves in Talamanca, Costa Rica. A total of 132,460 dung beetles of 52 species and
913 tracks of 27 terrestrial mammal species were registered. Dung beetle species richness and
diversity were greatest in the forests, intermediate in the agroforestry systems and lowest in the
plantain monocultures, while dung beetle abundance was greatest in the plantain monocultures.
The number of mammal tracks per plot was significantly higher in forests than in plantain
monocultures, whereas mammal species richness was higher in forests than in either cocoa agro forestry systems or plantain monocultures. Species composition of both terrestrial mammals and
dung beetles also varied across the different land use types. Our study indicates that indigenous
cocoa and banana agroforestry systems maintain an intermediate level of biodiversity (which is less
than that of the original forest but significantly greater than that of plantain monocultures) and
provide suitable habitat for a number of forest-dependent species. Although the agroforestry
systems appear to serve as favorable habitats for many terrestrial mammal species, their potential
positive contribution to mammal conservation is being offset by heavy hunting pressure in the
reserves. As in other agricultural landscapes, the conservation of biodiversity in Talamanca will
depend not only on maintaining the existing forest patches and reducing the conversion of tradi tional agroforestry systems to monocultures, but also on reducing hunting pressure | es_ES |
