The research was developed during five years, in order to evaluate the faunistic performance in a silvopastoral system intended for beef cattle. A mixed linear model was applied where the year, season and the year by season interaction were used as fixed effects, and the quadrants were used as random effect. The ecological indexes number of individuals, richness and diversity were determined. The tree survival and biomass production were also determined, and a biological carrying capacity index was analyzed. Simple regression analyses were made among the biomass, the trees, and the indexes number of individuals and diversity. Difference (p < 0,001) was observed in the number of total individuals between the two initial years, while the second did not differ from the third and the fourth year differed from the fifth. The richness indicator differed (p< 0,001) among the different years. Likewise, there were differences (p< 0,001) in the biological diversity and positive relations were found among the tree component, the biomass and the indexes total individual number and species diversity. It is concluded that the silvopastoral system, as cover model, allowed a wider habitat for faunistic development, and improved the relation of the ecological indexes due to the presence of the trees and the increase of biomass in the system
