Distribution of three monkey species along a gradient of regenerating tropical dry forest Original Research Article

Only 2% of tropical dry forest in Central America remains undisturbed; consequently habitat regeneration is the best option to provide adequate areas of habitat for wildlife. This study examined the influence of a forest regeneration gradient (0–180 years since pasture abandonment) on the densities of white-faced capuchins (Cebus capucinus), howling monkeys (Alouatta palliata), and spider monkeys (Ateles geoffroyi) in the tropical dry forest of Santa Rosa National Park, Costa Rica. Monkey densities and tree characteristics were sampled using 600 m transects within each of 14 sites from February to June 1996. Densities of all three monkey species were higher in older forests and in forests with greater food biomass estimates. The results indicate that monkey habitat, and consequently viable monkey populations, can be regained through protection and natural regeneration of tropical dry forest.
