This bill establishes a federally funded program to reduce wildfires and environmental damage along the U.S.-Mexico border by focusing on vegetation management and fuel reduction on federal lands. The Southern Border Fuels Management Initiative, to be set up by the Interior Secretary within one year, will carry out activities like reducing hazardous fuels, removing invasive plants, and installing fuel breaks on federal lands within border units, while coordinating with Border Patrol and law enforcement to improve sight lines and operational control. The bill authorizes $3.66 million annually for seven years to implement these activities and requires the government to develop protocols addressing wildfire ignition and environmental degradation on federal borderlands, with a report to Congress within one year detailing incidents, costs, and needed resources. The program will terminate seven years after enactment, and an updated federal report on wildland fire management will include information specific to border states.
