Yellow Starthistle

The Asotin County NWCB is no longer accepting applications for the 2019 Yellow Starthistle Cost-Share Program.

Plant Overview-

Yellow starthistle is a scourge to range lands throughout the west. This winter annual is toxic to horses and is capable of drastically reducing biodiversity by overwhelming vast swaths of landscapes forming dense monocultures. The spiny heads of mature plants are unpleasant in recreational areas and unpalatable to most animals save for goats and, even after several mowings, plants can produce mature seed. Seeds of yellow starthistle plants can remain viable for as long as 10 years while some estimate even longer viability.


Cost-Share Program Details–

  • The Asotin County NWCB (NWCB) offers a 1:1 dollar matching rate up to a $500 expense by the NWCB per landowner (e.g. NWCB contributes $500, landowner contributes $500) for the treatment of yellow starthistle. Expenses beyond this $500 NWCB cost-share limit will be the responsibility of the landowner. Treatments/projects are not limited to $1000, however the landowner will be fully responsible for expenses beyond this amount.
  • Maximum benefit of $500 per landowner.
  • Costs exceeding either dollar limit will be paid for by the landowner.  For example: a yellow starthistle job costs a contractor $1200. The owner pays $700 while the NWCB pays only its $500 offered limit. If a job costs a contractor $800, both parties pay $400.
  • Work will be done on a first-come first-serve basis until funds are exhausted or environmental conditions prohibit treatment.
  • Timings of aerial applications are determined by the pilots and their schedules and usually occur in the latter half of May to the early June.
