Invasive Plant Management in the Salem District Prevention and detection Education and awareness Inventory Planning Integrated weed management Coordination Monitoring, evaluation, research and technology transfer

Northwest Weed Management Partnership An informal multi-agency network of individuals and organizations concerned with rural and urban invasive weed issues in northwestern Oregon and southwestern Washington. Six Cooperative Weed Management Areas and Four Species Working Groups Knotweed False brome Garlic mustard Meadow knapweed

Cooperative Weed Management Area Advantages Technology transfer and information sharing Early Detection Rapid Response Partnered projects Annual Management and Operating Plans: –Weed control and inventory projects –Outreach and education on priority species to slow further spread and gain support for control efforts

Working Group Benefits –Coordination of education, inventory & prevention activities –Sharing of technical information on control methodologies and inventory results –Funding leveraging opportunities for inventory and control projects –Support for biocontrol research efforts

Pesticide Application Records (PARs) – 24 /10

Biological Control in the Salem District Coordinated through the Oregon Department of Agriculture Uses approved natural enemies to invasive plants Important integrated weed management tool since the 1970’s Salem District already had a good distribution of available biological control agents in 1995 No new releases have been made on Salem District administered lands since before 1995

Current herbicide use: glyphosate If we could we would also be using: Imazapyr

Manual Control at Fishermen’s Bend

False brome manual treatment

Biological Control at Minsinger Bench

How Vegetation Treatment EIS Would Help Ability to treat invasive species other than officially listed noxious weeds with herbicides. Improve rapid response capabilities with more effective herbicides Easier to effectively coordinate with neighbors and partners on treatment projects Improve long term success and landscape health Reduce long term costs
