Plant Overview-

Rush Skeletonweed is a menace to rangeland ecosystems; capable of reproducing by root as well as seed, this perennial member of the sunflower family boasts formidable versatility through its substantial root system, a capacity to flourish during drought, all too easily wind-borne seed, very little leaf surface by which to translocate many common herbicides and the ability to produce offspring from root fragments as small as 1/2″ rendering digging or tillage as very unfavorable control methods.

The ACNWCB considers this specie as one of the most significant threats to natural resources in the county and is a “Class B Designate” noxious weed meaning that the specie is designated for control as it is currently not ubiquitously widespread in our area.


Cost-Sharing Details-

BenefitThe ACNWCB offers a 1:1 matching rate up to a $500 expense by the weed board per landowner ((e.g. ACNWCB contributes $500, landowner contiributes $500) for the treatment of rush skeletonweed. Expenses beyond this $500 ACNWCB cost-share limit will be the responsibility of the landowner.

Work will be done on a first-come first-serve basis until funds are exhausted or environmental conditions prohibit treatment.
