Background A hiking trail is one of the major recreational activities that have critical impacts on wildlife. Wadi Telah in Saint Katherine Protectorate (South Sinai, Egypt) (N 28.568539 and E 33.932816) is an important spot for biodiversity. It was surveyed for spatial variation in the diversity of flower-visiting insects at different distances from the hiking trail. The current study aimed at assessing the impact of some anthropogenic activities along the main hiking trail passing through W. Telah on the diversity of flower-visiting insects. Field monitoring of flower visitors across the hiking trail passing through W. Telah was carried out at different distances (~ 0, 20, 40, and 60 m) along both sides of the hiking trail. As a control, monitoring was performed at 120 m from the hiking trail. Results A total of 542 individuals belonging to 34 species of flower visitors, 16 families, from three orders were recorded within the study localities in W. Telah. Floral resources in Wadi Telah can be a limiting factor for the populations of flower visitors. There was a significant difference in the distribution of the flower visitors’ species richness among different distances from the hiking trail in W. Telah. Species richness and abundance of flower visitors and their associated floral resources were significantly positively correlated to the distance from the hiking trail. There were no significant differences in the diversity of flower-visiting insects among different distances from the trail, perhaps due to their mobility. Conclusions The present study showed that the hiking trail had a negative impact on flower visitors and their associated floral resources in Wadi Telah. The investigation on how different biodiversity elements respond to hiking trails allows greater insight for protectorate managers. The study can contribute to effective management decisions for current and future protectorates.

远足小径对埃及圣凯瑟琳保护区 Wadi Telah 探花昆虫多样性的影响

背景 远足径是对野生动物有重大影响的主要休闲活动之一。位于圣凯瑟琳保护区（埃及南西奈半岛）（N 28.568539 和 E 33.932816）的 Wadi Telah 是生物多样性的重要场所。调查了距离远足径不同距离的访花昆虫多样性的空间变化。目前的研究旨在评估沿着穿过 W. Telah 的主要远足小径的一些人为活动对探花昆虫多样性的影响。对穿过 W. Telah 的远足径上的花卉游客进行实地监测，沿远足径两侧的不同距离（~ 0、20、40 和 60 m）进行。作为对照，在距离远足径 120 m 处进行监测。结果在W. Telah 的研究地点共记录了来自三个目34 种16 科34 种花客的542 只个体。Wadi Telah 的花卉资源可能是花卉游客数量的限制因素。W. Telah远足径不同距离的花客物种丰富度分布存在显着差异。花卉游客的物种丰富度和丰度及其相关花卉资源与与远足径的距离呈显着正相关。与小径不同距离的访花昆虫的多样性没有显着差异，这可能是由于它们的移动性。结论 本研究表明，远足小径对 Wadi Telah 的花卉游客及其相关花卉资源产生负面影响。对不同生物多样性元素如何响应远足径的调查可以让保护区管理人员更深入地了解。该研究有助于为当前和未来的保护国做出有效的管理决策。
