Upper Snake River CWMA

Spray Days

"

  Spray Days" offer a good opportunity for the USRCWMA "Weed Warriors" to join forces on high priority noxious weed 

   issues.  The CWMA typically supplies the required herbicides.  County weed departments as well as state and federal

   agencies supply the labor and equipment to apply the treatment.

   The Highway 33 spray day started in 2001.  During 2007 A post treatment inspection following the HIGHWAY 33 SPRAY DAY

   showed that the 90 acres of chemical treatments were 90% effective.  Eleven people representing 5 different organizations

   treated one of the worst areas of the project.

   The BITCH CREEK LEAFY SPURGE SPRAY DAY was a cooperative effort with the Henrys Fork CWMA and the Upper Snake

   River CWMA.  Our objective was to contain the Leafy Spurge along the border of Teton and Fremont Counties.  Over twenty-

   three people, representing private landowners, multiple counties, US Forest Service, ID Fish and Game, and the BLM

   participated in this extremely successful spray day.  Approximately 140 acres of Leafy Spurge were treated and over 200

   acres were inventoried.  Thanks to the efforts of so many individuals and organizations, this project should only take a small

   crew a day or two to touch up next year.  

   A post treatment inspection of the ROADHOUSE RIVER BEND SPRAY DAY showed that the 120 acres treated was greater

   then 90% effective. 18 people representing 6 different organizations and 1 private individual.  The treated area was made up

   of county right-of-way, rail road plus right-of-way, private land, and BLM.  What was great about this project is the fact this

   land is next to the Snake River and has potential for wildlife habitat.  Once the noxious weeds are under control which may

   take one more year a re-vegetation effort will be put into place to turn all of this land into habitat for wildlife.

   The MENAN LEAFY SPURGE CONTROL PROJECT continues to

   target leafy spurge in the Menan and Lewisville areas of Jefferson

   County.  Ditch banks, riparian areas, roadsides, and non cropland

   are already infested or threatened by this aggressive invader.

   Throughout the summer the Jefferson County Weed Control

   continued to treat roadsides and Right of Ways while private

   landowners treat their lands. In September, 2007 CWMA partners

   from the Forest Service, Jefferson, Bonneville, Fremont, Clark and

   Madison counties joined forces with private land owners to

   complete a MENAN LEAFY SPURGE SPRAY DAY. Approximately

   200 additional acres were treated.
