The conservation game

Conservation problems typically involve groups with competing objectives and strategies. Taking effective conservation action requires identifying dependencies between competing strategies and determining which action optimally achieves the appropriate conservation goals given those dependencies. We show how several real-world conservation problems can be modeled game-theoretically. Three types of problems drive our analysis: multi-national conservation cooperation, management of common-pool resources, and games against nature. By revealing the underlying structure of these and other problems, game-theoretic models suggest potential solutions that are often invisible to the usual management protocol: decision followed by monitoring, feedback and revised decisions. The kind of adaptive management provided by the game-theoretic approach therefore complements existing adaptive management methodologies.     

人工捕杀赤腹松鼠以防治其对人工林危害的效果观察

赤腹松鼠是洪雅林场第一大林业有害生物,林场在人工柳杉林区设立固定监测样线对赤腹松鼠实施专项监测。监测数据表明,2006年以前林场受到赤腹松鼠危害的人工柳杉林面积达0.76万hm2。2006年至今,林场采用人工捕杀的方式防治赤腹松鼠对人工林的危害,取得了明显的防治效果,赤腹松鼠危害面积下降为0.32万hm2。
