Conservation science aims to identify the factors influencing the distribution of threatened species, thereby permitting the implementation of effective management strategies. This is key for long-lived species that require long-term monitoring such as the worldwide endangered Egyptian vulture (). We studied temporal and spatial variations in the distribution of breeding pairs and examined the intrinsic and anthropic factors that may be influencing the abundance of breeding territories in continental Spain. Based on the census data of breeding pairs from 2000, 2008, and 2018, we used Rank Occupancy-Abundance Profiles to assess the temporal stability of the population and identified the spatial heterogeneity through a Local Index of Spatial Autocorrelation analysis. The GLMs showed that the abundance distribution was mainly influenced by the abundance of griffon vultures () and cattle at a regional scale. Nonparametric comparisons showed that the presence of wind farms had a significant negative effect on local breeding pairs abundance, but that supplementary feeding stations and food resource-related variables had a positive impact. In light of these findings, we recommend a hierarchical approach in future conservation programs involving actions promoting regional-scale food resource availability and highlight the need to address the negative impact of wind farms at local levels.
保护科学旨在确定影响濒危物种分布的因素，从而能够实施有效的管理策略。这对于像全球濒危的埃及秃鹫这样需要长期监测的长寿物种来说至关重要。我们研究了繁殖对分布的时空变化，并考察了可能影响西班牙大陆繁殖领地数量的内在因素和人为因素。基于2000年、2008年和2018年繁殖对的普查数据，我们使用秩占有 - 丰度剖面图来评估种群的时间稳定性，并通过局部空间自相关分析确定空间异质性。广义线性模型显示，在区域尺度上，丰富度分布主要受兀鹫和牛的数量影响。非参数比较表明，风力发电场的存在对当地繁殖对数量有显著负面影响，但补充饲养站和与食物资源相关的变量有积极影响。鉴于这些发现，我们建议在未来的保护计划中采用分层方法，包括促进区域尺度食物资源可用性的行动，并强调在地方层面应对风力发电场负面影响的必要性。
