Salem District12 northwest Oregon counties
Approximately 403,000 acres
BLM usually manages a small percentage of the land in any particular fifth-field watershed
Fragmented ownership pattern
Control methods: herbicides, mechanical, manual and biological control
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

NEPA Coverage
• Westside Salem Integrated Non-Native Plant Management Plan Decision Rationale EA # OR080-06-09
• Cascades Resource Area Invasive Non-Native Plant Management Environmental Assessment Decision Rationale EA # OR-080-02-02
• Both tiered to the Record of Decision for the Northwest Area Noxious Weed Control Program (May 1987)
Pesticide Use Proposals (PUPs) etc.
• PUPS ensure compliance with applicable laws, policies and NEPA decisions.
• Five levels of review and approval culminating with the deputy state director
• Adjacent land owners notification and coordination
• Applications are done by contractors and cooperators.
• 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
