摘要

加拿大不列颠哥伦比亚省的南部山地驯鹿(Rangifer tarandus caribou, SMC)正经历着急剧的数量下降和范围萎缩。2019年,最南端的两个鹿群,南塞尔柯克鹿群和珀塞尔-南鹿群,在功能上已经灭绝,濒临灭绝。为了拯救剩余的动物,使用软释放方法将它们转移到哥伦比亚北部的牧群范围。这些被转移的动物与一只圈养的一岁幼崽和一只来自哥伦比亚北部SMC牧群的成年雌性一起被释放。对二级生境选择行为的比较表明,放归动物对生境和海拔条件的反应与居住驯鹿相似。Purcells-South和South Selkirks个体的迁移和软释放表明,野生迁移和人工饲养的SMC的软释放是成功的,应该考虑在可行的地点和时间。

Translocation of southern mountain caribou using a soft-release technique
Southern mountain caribou (Rangifer tarandus caribou, SMC) in British Columbia, Canada, are experiencing a precipitous population decline and range recession. In 2019, the two southernmost herds, the South Selkirks and the Purcells-South herds, were functionally extirpated and facing imminent extinction. To rescue the remaining animals, a translocation into the Columbia North herd range was performed using a soft-release method. The translocated animals were released alongside a captive-reared yearling and a resident adult female from the Columbia North SMC herd. A comparison of habitat selection behaviours at the 2nd order of selection demonstrated that the released animals responded to habitat and elevational conditions similarly to resident caribou. The translocation and soft release of Purcells-South and South Selkirks individuals demonstrates that soft release of wild translocated and captive-reared SMC can be successful and should be considered where and when feasible.
