Bog Spicebush Lindera subcoriacea is a U.S. Department of Defense DoD Species at Risk SAR that has recently been proposed for listing under the Endangered Species Act. Roughly 60 percent of all known Bog Spicebush populations are found on five DoD installations Fort Bragg, Camp Mackall, Fort Jackson, Eglin Air Force Base AFB and Camp Shelby Joint Forces Training Center JFTC. This recently described species has been reported to occupy a variety of plant communities that have varying disturbance dependence, suggesting the habitat suitability of occupied sites is spatially and temporally dynamic. Additional information about Bog Spicebush habitat requirements and potential distribution is needed to inform assessments of the species conservation status and management needs. This project used MaxEnt, a widely applied species distribution modeling approach to generate a range-wide habitat suitability map. This map was also used to identify 1 sites warranting targeted surveys for novel populations, 2 suitable habitat for conservation and management, and 3 sites suitable for population reintroduction.
