This study was conducted to see whether herpetofaunal assemblage differed amongst hiking trails, undisturbed forest and urban areas within the Margalla Hills National Park, Islamabad Capital Territory, Pakistan. Circular plot area-constrained searches (45 plots in each habitat, each plot with an area of 25 m2) were used from March 2018 to July 2019. We recorded seven amphibian species, nine lizard species and six snake species. The species richness of amphibians and lizards was the same in the studied strata, while the detection and encounter rate of snakes was lower in the undisturbed forest and urban areas. The encounter rate of amphibians differed significantly between urban areas and hiking trails/undisturbed forest. The encounter rate and population density of lizards differed significantly between undisturbed forest and urban areas. The most frequently encountered amphibian species along the hiking trail and urban areas was Duttaphrynus stomaticus, with Hoplobatrachus tigerinus in undisturbed forest. The most common and frequently encountered lizard species along the hiking trail and urban areas was Hemidactylus brookii, while the Ophisops jerdonii was the most frequently seen in undisturbed forest. The most common and frequently encountered snake species along the hiking trail and undisturbed forest was the Indotyphlops braminus, while Ptyas mucosa was the most common in urban areas. The subsequent bio-assessment, based on herpetofauna, of the Park revealed good to excellent biotic integrity The Park faces threats including livestock grazing, alien invasive vegetation and human disturbance due to settlements, restaurants and tourism-related activities. While several of these threats have been mitigated since the establishment of the Islamabad Wildlife Management Board, the Park still requires improved management, especially regarding regulating tourism.

沿栖息地梯度进行的实地调查显示，巴基斯坦伊斯兰堡的玛加拉山国家公园的爬虫类动物种群差异

进行这项研究的目的是为了查看巴基斯坦伊斯兰堡首都领地的玛格拉山国家公园内远足径，未受干扰的森林和市区之间的爬虫爬行类植物群是否不同。从2018年3月到2019年7月，使用圆形地块面积受限搜索（每个栖息地45个地块，每个地块面积25 m2）。我们记录了7个两栖类，9个蜥蜴类和6个蛇类。在所研究的地层中，两栖动物和蜥蜴的物种丰富度相同，而在未受干扰的森林和城市地区，蛇的检出率和遭遇率较低。在城市地区和远足径/未受污染的森林之间，两栖动物的遭遇率差异很大。在未受干扰的森林和城市地区，蜥蜴的遭遇率和人口密度显着不同。远足径和市区内最常遇到的两栖动物是达塔芬斯通体（Duttaphrynus stomaticus）。远足径和市区最常见，最常遇到的蜥蜴种是布鲁克海豚（Hemidactylus brookii），而在未受干扰的森林中最常见的是桔小鳄。远足小径和未受干扰的森林中最常见和最常遇到的蛇种是Bradous indotyphlops，而城市中最常见的是粘膜脓杆菌（Ptyas mucosa）。随后基于Herpetofauna进行的公园生物评估显示出良好至极佳的生物完整性。公园面临的威胁包括放牧，外来入侵性植被以及定居点，饭店和旅游相关活动对人类的干扰。
