The project consists of an inventory and treatment phase for orange hawkweed. Treatment sites are located in the Mission Creek, Lapwai Creek, and Sweetwater Creek drainages. The treatment site consists of approximately 15 acres owned by 2 private landowners. The site was inventoried and mapped in the summer of 2008 and 2009. The landowner will treat the weeds. The inventory phase is for two adjacent landowner parcels where the weed has been spotted. The inventory will identify the extent and the location of the orange hawkweed and result in a treatment plan for 2011.
NPSWCD recognizes that control of invasive plants species in potential restoration areas needs to occur prior to any further restoration activities.
This project is a partnership effort with the Idaho Department of Agriculture, Clearwater Basin Cooperative Weed Management Area, the Nez Perce Soil and Water Conservation District and the Bonneville Power Administration.
The project addresses the following goals from the Clearwater Basin Weed Management Area strategy:
Goals from the CBWMA strategy:
The following goals from the CBWMA strategy (A Strategy for Invasive Plant Management in the Clearwater River Basin - November, 2002) are addressed with this proposal.
- Prevent the introduction, reproduction, and spread of noxious weeds and invasive plants into and within the Clearwater River Basin.
- Eradicate new outbreaks of established invasive plants.
- Reduce the density of established noxious weeds and invasive plants to a point that natural resource damage is within acceptable limits.
- Implement the most economical and effective control methods for the target species.
This proposal addresses the following management priorities listed in the CBWMA strategy (2002):
4th Control noxious weeds or invasive plants along transportation corridors and areas of concentrated activities, such as roads, trails, campgrounds, trailheads parking lots and gravel pits
Specific Relationship: Control orange hawkweed along logging roads.
6th Contain established noxious weeds and invasive plants
Specific Relationship: Noxious weeds and invasive plants are geographically contained and are not increasing beyond the perimeter of the infestation. Orange hawkweed is contained to current geographic area. Treatment reduces ability of invader to spread to other areas.
7th Reduce the density or slow the spread of widespread established invaders
Specific Relationship: Invasive weed density and rate of spread will be reduced as a result of treating identified areas.
