摘要
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。
Callosciurus erythraeus is one of harmful animals in forest and often does grave damage to for- est. About 7 600 hm2 of artificial forest in Hongya Forest Farm were damaged by red-bellied squirrels be- fore 2006. The workers of the farm and the local residents have been encouraged to hunt red-bellied squirrels since 2006. More than 240 000 squirrels have been hunted. Therefore the population of the squirrels have reduced, and the damaged area has decreased to 3 200 hm2.
