白冠长尾雉野外放归初期活动范围及变化规律

Movement range and variation of Syrmaticus reevesii in the early stage after release in the wild

为了加强珍稀濒危雉类物种保护,推进珍稀濒危雉类种群复壮进程,2021年9月在湖南壶瓶山国家级自然保护区放归了40只人工繁育的白冠长尾雉成体,利用红外自动数码照相机和GPS卫星定位信号发射器对放归的白冠长尾雉进行监测研究。结果显示:红外相机监测获得28张白冠长尾雉独立有效照片;给10只白冠长尾雉安装PTT,10只个体放归后每10d的移动距离为(448.34±309.80)m,活动范围(68753.99±59706.90)m^(2);白冠长尾雉在放归后的前20d移动距离和活动范围较小且比较稳定,在21~50d移动距离和活动范围逐渐增大,在51~70d移动距离和活动范围稍微减小,在71~80d移动距离和活动范围又逐渐增大达到最大值,在81~90d移动距离和活动范围减小;10只白冠长尾雉个体平均分布海拔为(1018.71±70.48)m,与其物种生态特性一致。本研究建议,后续进行雉类野外放归时应加强雉类野化训练,扩大野外放归范围,提高野外放归成功率。

To strengthen the protection of rare and endangered wild pheasant species and promote the rejuvenation of rare and endangered pheasant populations,we studied 40 artificially breeding Syrmaticus reevesi released in the Huping Mountain National Nature Reserve in Hunan Province in September 2021,and the infrared automatic digital camera and GPS satellite positioning signal transmitter were used to monitor the objects.The results showed that 28 independent-and-effective photos of Syrmaticus reevesi were obtained with the infrared camera.Platform transmitter terminals were installed on 10 Syrmaticus reevesi and the movement distance was obeserved as(448.34±309.80)m and the activity range was(68753.99±59706.90)m^(2)every 10 days.The Reeves's pheasant's movement distance and activity range were small and steady in the first 20 d after released,gradually increased in 21~50 d and slightly decreased in 51~70 d,gradually increased to the highest values in 71~80 d and decreased in 81~90 d.The average distribution altitude of Syrmaticus reevesi was(1018.71±70.48)m,which was consistent with the ecological characteristics of the species.In this study,it is suggested to strengthen the field training and expand the field release range so as to promote the success rate of the pheasant release.
