Watershed Restoration Program Prevent, Control, or Eradicate Terrestrial Invasive Species
LTBMU seeks to substantially increase annual inventory and eradication of terrestrial invasive plant species (TIPS) infestations on National Forest System lands in the Basin. Completion in 2010 of an EA for integrated manual and herbicide treatments, creating the TIPS program, was followed by 5 years of successful field implementation that resulted in eradicated weed infestations outpacing occurrences of new weed infestations. Lack of comparable funding since 2016 has reversed the trend, with new infestations leading.
