1 Subsistence Hunting in the Río Plátano Biosphere Reserve, Honduras: A Comparison of Game Abundance in Hunted and Protected Areas. Yannick Cabassu M.Sc. Candidate Department of Geography and Environmental Studies Carleton University Ottawa, Canada CAG Annual Meeting Saskatoon, Saskatchewan June 1, 2007

2 Research Objectives Goal: To Investigate the effects of subsistence hunting on wildlife populations in the Río Plátano Biosphere Reserve, Honduras. Specific Aims: To compare the relative abundance of game species between a hunted site in the cultural zone of the biosphere and a non-hunted or lightly-hunted site in the nucleus zone using direct and indirect observations.

3 Man and the Biosphere Reserve Conservation Function – to contribute to the conservation of landscapes, ecosystems, species and genetic variations. Development function – to foster economic and human development which is socio-culturally and ecologically sustainable. (UNESCO’S MAB Program 2005)

8 Direct and Indirect Observations of Game Species per Kilometer Around the Village of Las Marías and in the Nucleus zone, Río Plátano Biosphere Reserve, May-Aug 2006.

10 Results 9/10 game species are significantly less abundant in the hunted region. 5/9 non-game species are significantly less abundant in the hunted region Higher abundance in protected area.

11 Discussion Game species less abundant in hunted region Non-game species also less abundant in hunted region Hunting or human presence? Lower abundance near the village (<2km) than away from it.
