Abstract Ecological habitat connectivity, human disturbances, and habitat availability are strongly related to each other for distribution and abundance of species. In Varjin protected area, Iran, habitat loss due to human pressures is the main factor in the rapid decline of Ovis orientalis (wild sheep) population. In this research, we proposed a framework to analyze the connectivity of the mountainous landscape by considering human disturbances. The integrated framework is aimed at obtaining a procedure that can be used to rank individual habitat patches for conservation priorities. We identified patches with high-risk values using the InVEST model. By applying patch removal techniques and in tandem with a fragmentation scenario, an analysis of the network-based modeling connectivity metrics was performed within and among the habitat patches. We evaluated the local and habitat connectivity by calculating Betweenness Centrality (dBC) as a network metric and Probability of Connectivity (dPC) as the habitat availability metric. Average dBC and dPC metrics decreased by 62.41 % and 8.23 %, respectively by applying risk values. Results demonstrated that habitat patches in the east and southeast of the protected area show the biggest difference value in response to human disturbance. These patches are the priorities for habitat conservation. Our methodology provides a habitat-based conservation tool by combining connectivity metrics and considering habitat risks. As a result, the impact of habitat loss on connectivity metrics and future vulnerability of the protected area is assessed in one procedure.

将栖息地风险评估和连通性分析整合到保护区保护栖息地斑块的排名中

摘要 生态栖息地连通性、人类干扰和栖息地可用性在物种分布和丰度方面彼此密切相关。在伊朗的瓦尔金保护区，由于人类压力造成的栖息地丧失是东方羊（野羊）种群迅速下降的主要因素。在这项研究中，我们提出了一个框架，通过考虑人为干扰来分析山区景观的连通性。综合框架旨在获得一个程序，该程序可用于对各个栖息地斑块进行优先保护排序。我们使用 InVEST 模型确定了具有高风险值的补丁。通过应用补丁去除技术并结合碎片化场景，对栖息地补丁内部和之间的基于网络的建模连接度量进行了分析。我们通过计算介数中心性 (dBC) 作为网络指标和连接概率 (dPC) 作为栖息地可用性指标来评估本地和栖息地连通性。通过应用风险值，平均 dBC 和 dPC 指标分别下降了 62.41% 和 8.23%。结果表明，保护区东部和东南部的栖息地斑块对人为干扰的响应差异值最大。这些斑块是栖息地保护的优先事项。我们的方法通过结合连通性指标和考虑栖息地风险来提供基于栖息地的保护工具。因此，栖息地丧失对保护区连通性指标和未来脆弱性的影响在一个程序中进行评估。
