摘要： 家畜放牧是威胁野生动物的重要因素之一, 明确野生动物对放牧干扰的响应对物种保护意义重大。自然保护区中散养的牛、马等家畜会破坏野生动物栖息地, 但关于家畜如何影响雉类时空分布格局的相关定量评估仍十分有限。本研究于2011–2015年选取四川王朗国家级自然保护区为研究区域, 以红腹角雉(Tragopan temminckii)和家畜(牛、马)为研究对象开展红外相机监测, 采用多物种占域模型(multi-species occupancy models)、核密度估计方法(kernel density estimation)和回避-吸引指数(avoidance-attraction ratios, AAR)探究家畜放牧对红腹角雉栖息地活动节律及占域的影响。结果显示, 在时间维度上, 红腹角雉的活动模式与家畜高度重叠(重叠系数∆4 = 0.74, 95% CI: 0.73–0.95), 行为上显著回避家畜(AAR = 3.17)。在空间维度上, 红腹角雉的边际占域率与灌木盖度(β = 0.16)、郁闭度(β = 0.06)呈正相关, 与凋落物(β = –0.36)、草本盖度(β = –0.41)、海拔(β = –0.20)、竹子盖度(β = –0.10)呈负相关; 家畜的边际占域率与郁闭度(β = 0.39)呈正相关, 与凋落物(β = –0.10)、距最近河流距离(β = –0.15)、海拔(β = –0.33)、灌木盖度(β = –0.54)、竹子盖度(β = –0.25)呈负相关。红腹角雉的栖息地利用同时受家畜以及其他生态因子的共同影响。家畜的存在改变了红腹角雉对竹子盖度、海拔和距最近河流距离的占域响应, 使其更倾向于利用竹子盖度较高、海拔较低且距最近河流较远的栖息地。我们建议对家畜放牧进行管控, 以促进王朗国家级自然保护区雉类种群及栖息地的恢复。

Abstract

Aims: Livestock grazing is one of the primary threats to wildlife, and elucidating the responses of wildlife to grazing disturbance is crucial for species conservation. Free-ranging livestock such as cattle and horses in nature reserves can degrade wildlife habitats. However, quantitative assessments of how livestock influence the spatiotemporal distribution patterns of pheasants remain scarce. 

Methods: From 2011 to 2015, we conducted this study at Wanglang National Nature Reserve in Sichuan Province, China. Camera trap surveys were implemented targeting Tragopan temminckii and livestock (cattle and horses). Multi-species occupancy models, kernel density estimation, and the avoidance-attraction ratios (AAR) were employed to investigate the effects of livestock grazing on the activity rhythm, habitat use, and occupancy of Tragopan temminckii. 

Results: The results revealed that in the temporal dimension, the activity pattern of Tragopan temminckii overlapped highly with that of livestock (coefficient of overlap ∆4 = 0.74, 95% CI: 0.73–0.95), and the species exhibited significant behavioral avoidance of livestock (AAR = 3.17). In the spatial dimension, the marginal occupancy probability of Tragopan temminckii was positively correlated with shrub coverage (β = 0.16) and canopy density (β = 0.06), but negatively correlated with litter layer (β = –0.36), herbaceous coverage (β = –0.41), altitude (β = –0.20), and bamboo coverage (β = –0.10). For livestock, the marginal occupancy probability was positively correlated with canopy closure (β = 0.39) and negatively correlated with litter layer (β = –0.10), distance to the nearest river (β = –0.15), altitude (β = –0.33), shrub coverage (β = –0.54), and bamboo coverage (β = –0.25). The habitat use of Tragopan temminckii was jointly affected by livestock and other ecological factors. The presence of livestock altered the occupancy responses of Tragopan temminckii to bamboo coverage, altitude, and distance to the nearest river, driving the species to prefer habitats with higher bamboo coverage, lower altitude, and greater distance from river. 

Conclusion: We propose that grazing management measures should be implemented to promote the recovery of pheasant populations and their habitats in Wanglang National Nature Reserve.
