The Kashmir musk deer (Moschus cupreus, hereafter KMD) is one of the top conservation priority species which is facing population decline due to poaching, habitat loss, and climate change. Therefore, the long-term survival and viability of KMD populations in their natural habitat require conservation and management of suitable habitats. Hence, the present study attempted to assess the suitable habitat of KMD in three protected areas (PAs) of the Western Himalayan region of Uttarakhand using the Maxent modelling algorithm. Our results suggest that Kedarnath wildlife sanctuary (KWLS) possesses the maximum highly suitable habitats (22.55%) of KMD, followed by Govind Pashu Vihar National Park & Sanctuary (GPVNP&S; 8.33%) and Gangotri National Park (GNP; 5%). Among the environmental variables, altitude was the major contributing factor governing the distribution of KMD in KWLS. In contrast, human footprint in GPVNP&S and precipitation in GNP were the major contributing factors governing the distribution of KMD in these respective PAs. The response curve indicated that habitats with less disturbance falling in the altitudinal zone of 2000-4000 m were the most suitable habitat range for the distribution of KMD in all three PAs. However, in the case of GNP suitable habitat of KMD increases with an increase in the value of variables bio_13 (precipitation of wettest month). Further, based on our results, we believe that the predictors of suitable habitat change are site specific and cannot be generalized in the entire distribution range of the species. Therefore, the present study will be helpful in making proper habitat management actions at fine scale for the conservation of KMD.
克什米尔麝香鹿(Moschus cupreus,以下简称 KMD)是保护优先级最高的物种之一,由于偷猎、栖息地丧失和气候变化,其数量正在减少。因此,为了长期保护和维持 KMD 在其自然栖息地的生存能力,需要对适宜栖息地进行保护和管理。因此,本研究试图使用最大熵建模算法评估北阿坎德邦西部喜马拉雅地区三个保护区(PA)的 KMD 适宜栖息地。
研究结果表明,Kedarnath 野生动物保护区(KWLS)拥有最多的高度适宜 KMD 栖息地(22.55%),其次是 Govind Pashu Vihar 国家公园和保护区(GPVNP&S;8.33%)和 Gangotri 国家公园(GNP;5%)。在环境变量中,海拔是影响 KWLS 中 KMD 分布的主要因素。相比之下,GPVNP&S 中的人为足迹和 GNP 中的降水是影响这两个保护区 KMD 分布的主要因素。响应曲线表明,海拔在 2000-4000 米之间、干扰较小的栖息地是 KMD 在这三个保护区内分布的最适宜栖息地范围。然而,在 GNP 中,KMD 的适宜栖息地随着变量 bio_13(最湿润月份的降水)值的增加而增加。
此外,根据我们的研究结果,我们认为适宜栖息地变化的预测因子是特定地点的,不能在物种的整个分布范围内推广。因此,本研究将有助于在精细尺度上对 KMD 进行适当的栖息地管理行动。
