Application of LiDAR to assess the habitat selection of an endangered small mammal in an estuarine wetland environment

Light detection and ranging (lidar) has emerged as a valuable tool for examining the fine-scale characteristics of vegetation. However, lidar is rarely used to examine coastal wetland vegetation or the habitat selection of small mammals. Extensive anthropogenic modification has threatened the endemic species in the estuarine wetlands of the California coast, such as the endangered salt marsh harvest mouse (Reithrodontomys raviventris; SMHM). A better understanding of SMHM habitat selection could help managers better protect this species. We assessed the ability of airborne topographic lidar imagery in measuring the vegetation structure of SMHM habitats in a coastal wetland with a narrow range of vegetation heights. We also aimed to better understand the role of vegetation structure in habitat selection at different spatial scales. Habitat selection was modeled from data compiled from 15 small mammal trapping grids collected in the highly urbanized San Francisco Estuary in California, US..., , , # Application of lidar to assess the habitat selection of an endangered small mammal in an estuarine wetland environment

激光雷达（Light Detection and Ranging，LiDAR）已成为研究植被精细尺度特征的重要工具。然而，激光雷达极少被应用于滨海湿地植被及小型哺乳动物栖息地选择的相关研究。
大规模人为改造活动已对美国加利福尼亚海岸河口湿地的特有物种构成威胁，其中包括濒危物种盐沼禾鼠（*Reithrodontomys raviventris*，简称SMHM）。
深入明晰盐沼禾鼠的栖息地选择机制，有助于管理者更高效地开展该物种的保护工作。
本研究评估了机载地形激光雷达影像在植被高度范围狭窄的滨海湿地中，测量盐沼禾鼠栖息地植被结构的能力。同时，本研究旨在进一步揭示植被结构在不同空间尺度下对栖息地选择的影响作用。
本研究基于在美国加利福尼亚州高度城市化的旧金山河口布设的15个小型哺乳动物诱捕网格所采集的数据，构建了栖息地选择模型……
