CAL FIRE – Butte County Begins Vegetation Management Project
CAL FIRE work to burn brush piles at the south end of Loafer Creek has been temporarily halted due to dry conditions. This work is part of their Vegetation Management Program which aims to reduce wildfire risk, improve public safety and enhance forest health around Lake Oroville. Approximately eight acres are targeted as part of DWR’s Fuel Load Management Plan (FLMP) to thin overstocked trees and vegetation that increase the intensity of wildfires. FLMP projects occur within the Oroville Facilities Federal Energy Regulatory Commission (FERC) Project boundary and FLMP projects are developed in coordination with federal, state and local fire and resources management agencies. Once sufficient rainfall has occurred to allow safe burning, the CAL FIRE activities will take place on weekdays throughout the spring.
