Book excerpt: Recognizing the increasing rate of species loss on a global scale and that neither pollution nor ecosystems respects political boundaries, cooperation on many different levels is required to conserve biodiversity. This volume uses four protected areas that Poland shares with its neighbors as case studies to explore opportunities to integrate science and management in transboundary protected areas in Central Europe for the conservation of biodiversity. Specific topics include biodiversity conservation theories and strategies, problems of wildlife management, and impacts of tourism and recreational use on protected areas.
