摘要

长尾雉(Catreus wallichii)是Kaligandaki河以西的一种保护物种。该研究于2016年10月至2017年6月在卡利甘达基河西部的Myagdi地区进行。采用声学调查和方形调查相结合的方法,对野鸡的生境和种群状况进行了研究。以7只/km2的密度估计有38只繁殖个体。研究还表明,野鸡对栖息地的暴露成分表现出偏好。他们喜欢在海拔1800-2400米之间的中等陡峭的东部斜坡(10-35°)和陡峭的南部斜坡(35-67°)。此外,低乔木密度和高草本密度对该物种的生境选择有显著影响。偷猎和栖息地破坏是研究地点的主要威胁,呼吁制定战略管理计划,以长期保护啦啦队野鸡。

Population status and habitat assessment of Cheer Pheasant (Catreus wallichii) in Western Nepal
Abstract The Cheer Pheasant (Catreus wallichii) is a protected species found abundantly to the west of Kaligandaki River. This study was conducted in the Myagdi district located in the western part of Kaligandaki River from October 2016 to June 2017. Our aim was to assess the habitat and population status of Cheer Pheasant, using acoustic survey and quadrate methods. A total of 38 breeding individuals were estimated in 7 bird/km2 density. The study also revealed that Cheer Pheasants showed a preference for exposure components of the habitat. They preferred moderately steep eastern slopes (10–35°) and steep southern slopes (35–67°) between 1800–2400 m elevations. Additionally low tree density and high herbs density showed a significant effect on the habitat choice of the species. Poaching and habitat destruction are the major threats in the study site, calling upon a strategic management plan for the long-term conservation of the Cheer Pheasant.
