Northern regions of Pakistan support a relatively large population of wild ungulates, the preferred prey of sympatric carnivores. The Asiatic ibex (Capra Ibex Sibirica) is one such an ungulate species which also serves as an important trophy animal. The maintenance of trophy hunting programs rely on estimates of harvestable population sizes derived from rigorous methods. The present study successfully used the double observer-based Capture-Mark-Recapture (CMR) method to produce a reliable and accurate estimate of the Asiatic ibex population in the Community Control Hunting Areas (CCHAs) of Socterabad, Gojal watershed and Khunjerab National Park (KNP). Surveys were conducted from February to March 2018 and from March to April 2019. The total ibex population was calculated to be 1075 individuals (95%CI ± 670) with a density of 1.43 ibex/km2 in Gojal watershed, followed by Socterabad with 856 individuals (95%CI ± 680) and a density of 6.24ibex/km2, and lastly KNP with 463 individuals (95%CI ± 93.5) and a density of 0.14ibex/km2. A total of 52 herds were sighted in Gojal watershed with mean size of 19 ibex/herd (SE ± 3.2). In Socterabad, 28 herds were sighted with mean size of 16.07 ibex/herd (SE ± 2.4) and in KNP 28 herds were sighted with average recorded size of 16.5 ibex/herd (SE ± 3.4). In KNP Sex ratios of female to young, female to yearling and female to male were 1:0.7, 1:0.4, and 1:0.5 respectively. The detection probability of observer two was less than observer one. Ibex biomass recorded is insufficient for current recorded snow leopard (Panthera uncia) and wolf (Canis lupus) population in the area. Our study validates the use of Capture Mark Recapture as a viable tool in discerning ungulate populations, and shows that the population of the Asiatic ibex is viable in the study area, making it suitable for trophy hunting programs but need to modify the hunting law.

对巴基斯坦北部地区可持续收成的亚洲山羊(Capra ibex sibirica)的关键评价。

巴基斯坦北部地区有较大数量的野生有蹄类动物,这是同胞食肉动物的首选猎物。亚洲高地山羊(Capra Ibex Sibirica)是一种有蹄类动物,也可以作为重要的奖杯动物。奖杯狩猎计划的维持取决于通过严格方法得出的可采种群规模的估计。本研究成功地使用了基于双观察者的捕获标记捕获(CMR)方法来对Socterabad,Gojal流域和Khunjerab国家公园(CCHA)的社区控制狩猎区(CCHA)中的亚洲高地山羊种群进行可靠而准确的估计( KNP)。调查于2018年2月至2018年3月以及从2019年3月至2019年4月进行。在戈贾尔流域,总ibex人口为1075个人(95%CI±670),密度为1.43 ibex / km 2,其次是Socterabad,人口为856个人(95%CI±680)和密度6.24ibex / km 2,最后是KNP,有463个人(95%CI±93.5),密度为0.14ibex / km 2。在Gojal流域共发现52个牛群,平均大小为19 ibex /牛群(SE±3.2)。在Socterabad,观察到28个牛群,平均大小为16.07 ibex /牧群(SE±2.4),在KNP中,观察到28个牛群,平均大小为16.5 ibex /牧群(SE±3.4)。在KNP中,女性与年轻人的性别比,女性与一岁的比例以及女性与男性的比例分别为1:0.7、1:0.4和1:0.5。观察者二的检测概率小于观察者一。记录的高地山羊生物量不足以记录当前的雪豹(Panthera uncia)和狼(Canis lupus)该地区的人口。我们的研究验证了使用“捕获标记捕获”作为识别有蹄类动物种群的可行工具,并表明亚洲高地山羊种群在研究区域内是可行的,使其适合于奖杯狩猎计划,但需要修改狩猎法。
