## Salem District

**Salem District**

- 12 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

## Manual/Mechanical Treatments in the Salem District

- A cumulative total of 3,800 acres have been treated on 96 sites since 1996.

**Scotch Broom**
**Himalayan blackberry**
**Tansy ragwort**
**Canada thistle**
**Bull thistle**
**11 other species**

## Herbicide use in the Salem District

**Herbicide use in the ****Salem District**

**A cumulative total of 167 acres have been treated on 52 sites in the Salem District since 2004.   **

## Salem District Integrated Weed Management 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

**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
