“…Populations of threatened and endangered species are often primarily or solely located on federal, state, and nongovernmental protected lands; therefore, the stability and persistence of many species rely on continued protection of these lands (Tazik and Martin, 2002).…”

“…Fort Hood faces increasing challenges to balance growing military training needs with endangered species conservation and compliance with the Endangered Species Act ([ESA] 1973;Gutzwiller andHayden 1997, Tazik andMartin 2002). Development projects are often small (e.g., 50 to 100 ha) and locating development can often be adjusted to minimize relative impact to species of concern if the resolution of available data allows.…”

. Using LiDAR-derived vegetation metrics for high-resolution, species distribution models for conservation planning. Ecosphere 4(3):42. http://dx.doi.org/10.1890/ES12-000352.1Abstract. Advances in remotely sensed data for characterizing habitat have enabled development of spatially explicit predictive species distribution models (SDM) that can be essential tools for management. SDMs commonly use coarse-grain metrics, such as forest patch size or patch connectivity, over broad spatial extents. However, species distributions are likely driven in part by local, fine-grained habitat conditions. Conservation and management are often planned and applied locally, where coarse predictions may be uninformative or not sufficiently precise. We investigated the integration of high-resolution LiDAR (Light Detection and Ranging) with avian point sampling data to develop a detection-corrected occupancy model to quantify habitat-occurrence relationships for two species with different habitats: the endangered golden-cheeked warbler (Setophaga chrysoparia) and black-capped vireo (Vireo atricapilla) on a military installation in central Texas. We compared occupancy models that used only the more conventional, coarse remotely sensed metrics to models that also incorporated high-resolution LiDAR-derived metrics for vegetation height and canopy cover, to assess their use for predicting distributions. Models including LiDAR-derived vegetation height and canopy cover metrics were competitive for both species, and models without LiDAR-derived vegetation height had substantially lower model weights and explanatory strength. Area under curve estimates for the highest ranked models were high for warblers (0.864) and moderate for vireos (0.746). Using the best supported models for each species, we predicted the occurrence distribution for both species. The resulting predictions provide a decision support tool that enables assessment of the status, impacts, and mitigation of impacts to endangered species habitat on the installation due to land management and military training activities that is more standardized and accurate than current assessment approaches based on visual gestalt of habitat and expert opinion. Additionally, although previous species distribution models have been created for our focal species, most fail to match the grain and extent of most management actions or include local, fine-grained metrics that influence distributions. In contrast, we demonstrate that use of LiDAR with species occurrence data can provide precision and resolution at a scale that is relevant ecologically and to the operational scale of most conservation and management actions.

“…Although some readers would dispute that powerline rightsof-way are wildlands, for example, those that are managed for dense scrub vegetation provide substantial pollination services (Russell et al 2005). Similarly, many military installations have large wildland communities that serve as reservoirs for protected species, despite the proximate disturbances from training (Tazik and Martin 2002).…”
