Introduction The Burns District and Vale District Bureau of Land Management (BLM) is proposing to implement emergency stabilization and burned area rehabilitation (ESR) actions on the Buzzard Complex fires located on the shared boundary between the two districts (See Map 1). Stabilization and rehabilitation actions would include treatments of invasive species, seeding of native and desirable non-native grass species, construction of temporary fences, repair of management fences and planting of shrub seedlings on key portions of the Buzzard Complex burned area. The Buzzard Complex consisted of the Buzzard Fire, the Riley Field Fire, the Bartlett Mountain Fire, the Beaver Creek Fire and the Saddle Draw Fire. Emergency stabilization and rehabilitation plans have
