“…Large herbivores are at the key connecting point of both bottom-up effects and top-down effects in the food web (Burkepile et al 2013;Roux et al 2019;She et al 2023). Obtaining accurate and detailed habitat factor information is a key factor for large herbivores' precise conservation and management (Howard et al 2014;Baker et al 2020), and it is difficult to master the habitat selection law of multi-dimensional space by studying habitat Recently, unmanned aerial vehicle (UAV) and groundbased LiDAR detection technology has gradually become cutting-edge technology for habitat research in multidimensional space (Davies et al 2019;Deere et al 2020), and the "foodscape" theory of wildlife nutrition ecology has been proposed and developed (Duparc et al 2020;Laura et al 2020). These technologies and theories open up opportunities for the precise conservation and management of large herbivores.…”
