18th International Conference on Bear Research & Management 18ava Conferencia Mundial Sobre la Investigación y Manejo de Osos November 4-11, 2007 Monterrey, Nuevo León, México 18th International Conference on Bear Research & Management INTERNATIONAL ASSOCIATION FOR BEAR RESEARCH & MANAGEMENT The IBA sponsors international conferences and workshops about bear biology, research, and management. The International Conference on Bear Research & Management is the largest of these conferences and is focused on all 8 bear species. The International Conferences are rotated between the Americas and Eurasia on an 18-month rotation. The International Association for Bear Research and Management (IBA) is a non-profit tax-exempt (USA tax # 94-3102570) organization open to professional biologists, wildlife managers and others dedicated to the conservation of all bear species. The organization has over 550 members from over 50 countries. It supports the scientific management of bears through research and distribution of information. The IBA sponsors international conferences on all aspects of bear biology, ecology and management. Many of the conference papers are published as peer-reviewed scientific papers in the journal Ursus. The eight bear species of the world pose significant research and management problems to governments, local authorities, wildlife biologists, land managers, park personnel, tribal councils, and private land owners. The public endures hardships caused by bears; the public wants bears to survive. Management responsibility for the bears and their habitats rests with numerous national and local agencies and councils. Encroaching civilization, involving land-use conflicts and resource utilization by human beings, has resulted in the decline or disappearance of bear habitat and bear populations in portions of their ranges. Continued viability of populations and the possible restoration of bears in certain areas, will be largely contingent upon a cooperative approach towards research, management, land use, and education, and will increase in cost as land values escalate. The IBA, an association primarily of professional biologists with an interest in bears, recognizes these difficult bear research and management problems faced by agencies and governments. Thanks to Our Sponsors Additional funding was recieved from Grupo Acero del Norte, DORRSA, Parque Ecologico Chipinque, and the Denver Zoo. We would also like to thank our special friends who went beyond the expected to help bring this conference to life: David Garza Laguera & Norma Alaniz, Elizabeth Spence Sellers, Katharine Armstrong Love, Cina Alexander Forgason, Othon Ruiz Montemayor, and the Martínez / Pámanes family of Monterrey. Special appreciation goes to Maria Guerra, Maria Eugenia Rodriguez, Becky Trant, Chris Reopelle, Jere Sepulveda, Yolanda Ballard, and Charity Lawson for their help. Guillermo Palomares of Impulsora de Rentas y Servicios privided excellent services and went beyond what was required to help us with arrangements. Arturo May provided translation services, as always, with a touch of humor. We also thank all of our volunteers and students from the Universidad Autonoma de Nuevo Leon and Texas A&M University-Kingsville who have worked so hard.
