Statement of Work (SOW) / Performance Work Statement (PWS)

The U.S. Army Corps of Engineers (USACE), Walla Walla District requires the removal of invasive vegetation from two areas within the Toothaker Habitat Management Unit (HMU) in Finley, Washington. The purpose is to prepare these areas for native habitat restoration.
