Longleaf pine woodlands on military installations support multiple uses, including the Department of Defense (DoD) training and testing mission; threatened, endangered, and sensitive species (TES) conservation; and forest commodities (e.g., timber, pine straw) production. This report documents strategies to manage TES and their habitats on a plant community basis, using methods that apply to multiple species, and using methods that apply across the southeastern region of the United States. This report combines the pine flatwoods and sandhills communities because they have several features that link them. Ecological descriptions are provided for each community, along with available information about community occurrences on DoD installations throughout the southeast region. Known occurrences of plant and animal TES associated with longleaf pine woodlands on DoD lands are also reported. Known and potential impacts to the integrity of longleaf pine woodlands as TES habitat, and to associated species are reported. Impacts may be related to habitat fragmentation, or changes in community composition, structure and function due to altered fire regime, hydrologic patterns, soil stability and structure, groundcover integrity, or the invasion of exotic or pest species. Management recommendations are made within an ecosystembased, adaptive management context.

Military training and testing mission requirements make up the highest priority land uses on Department of Defense (DoD) lands. The U.S. Armed Forces require realistic, relatively natural, and expansive areas for adequate training. Training activities can lead to degradation of sensitive natural resources, but they also produce benefits. An ecosystem-based approach to managing threatened, endangered, and sensitive species (TES) and other natural resources provides DoD with an efficient, effective, and flexible framework for evaluating impacts, assessing natural resources, and generating management solutions to potential conflicts between training and TES conservation. Any increase in understanding about the habitat requirements of listed TES species will assist training and natural resource personnel in complying with the Endangered Species Act while avoiding restrictions on the military mission. This report is to be used by DoD natural resource policymakers, installation land managers, and the natural resource research community, in conjunction with associated documents produced by this SERDP work unit to (1) develop ecosystem-based approaches to describe natural communities and TES habitat in relation to military activities, (2) evaluate military-related effects on those communities, (3) develop community-based strategies for supporting both military land use and TES habitat management, and (4) develop management solutions for military impacts to natural communities when management for TES habitat is a priority for a particular location.

Florida Scrub on military installations supports a number of land uses including the Department of Defense (DoD) training and testing mission and threatened, endangered, and sensitive species (TES) conservation. This report documents strategies to manage TES and their habitat on a plant community basis, using methods that apply to multiple species occurring in scrub within the state of Florida. This report provides ecological descriptions of the community, along with available information about community occurrence on DoD installations in Florida. CO o CO o CD Known occurrences of plant and animal TES are also included. Known and potential impacts to the integrity of the community as TES habitat and to associated species are reported. Impacts are related to habitat fragmentation, and changes in community composition, structure and function due altered fire regime, hydrologic patterns, groundcover integrity or the invasion of exotic species. Management recommendations are made within as ecosystem based, adaptive management context.
