ASSESSING CONSERVATION PRIORITIES AND OPPORTUNITIES IN LOS SANTOS, PANAMA: A METHODOLOGY FOR SPATIALLY-EXPLICIT, SOCIOECOLOGICAL FOREST CONSERVATION PLANNING By MICHAEL L. BAUMAN A THESIS PRESENTED TO THE GRADUATE SCHOOL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE UNIVERSITY OF FLORIDA 2015 © 2015 Michael L. Bauman To Larry A. Wilson, Anthony Martin, and Stephanie A. Bohlman ACKNOWLEDGMENTS Acknowledgements go to my graduate committee, Claudia, Stephen, and especially to Stephanie, for helping me get to the end. Acknowledgements also go to the Azuero Earth Project, the Farmer’s and Rancher’s association of Los Asientos. Special thanks to the community of Los Asientos for sharing their time and knowledge and to Marie and Yeya for opening their homes. Similarly, thanks go to former Peace Corps Volunteers Katie and Bracken Kilpatrick and Katie Van der Bilt, who introduced me to their communities. A special thanks to Nuevo Ocu, who helped me get a tow truck for my field vehicle. For funding and support of the project, acknowledgements also go to the Tropical Conservation and Development program, the School of Natural Resources and Environment. 4 TABLE OF CONTENTS page
