PURPOSE AND NEED FOR DEVELOPMENT OF THIS FIRE MANAGEMENT PLAN The purpose is to implement an improved and updated Wildland Fire Management Plan (FMP) for Big Bend National Park. The fire management plan provides a framework for making fire-related decisions and serves as an operations manual. Updating the 1994 plan allows changes in fire policy, fire behavior knowledge, prescribed burn results, and revisions in NPS policies to be implemented in practice. By incorporating new information about ecology, fire effects and firefighting techniques, the FMP will improve the protection of people, property, and resources within the park. Current resource managers acknowledge three major challenges in managing vegetation at the park: greatly increased fuels in forest and some woodlands increasing risk from high-severity fire; invasion of fire-adapted nonnative plant species which threaten to displace native species primarily along the riparian corridor and drainages; and, altered fire patterns from suppression and grazing of livestock. Prioritizing and meeting these challenges requires
