We conducted a study at the privately owned El Zota Biological Field Station in Costa Rica to assess the effects of forest management techniques on primate ecology and behavior. While many conservation-oriented studies note the need for “corridors” to promote dispersal between isolated habitat fragments, few studies provide quantitative information on their use by primates. From July to August 2002, we studied the three primate species that occur at the El Zota Biological Field Station in Costa Rica — Cebus capucinus, Ateles geoffroyi, Alouatta palliata — to compare their use of planted versus naturally forested areas. We collected approximately 25 hours of data to quantify the general activities exhibited by primates in these types of habitat.
