About this file
This file is an attachment listing Wyoming's state-designated noxious weeds that are subject to control and eradication requirements. The list contains 32 weed species identified by common and scientific names, including field bindweed, Canada thistle, leafy spurge, perennial sowthistle, quackgrass, hoary cress, perennial pepperweed, ox-eye daisy, Russian knapweed, yellow toadflax, Dalmatian toadflax, Scotch thistle, musk thistle, spotted knapweed, diffuse knapweed, purple loosestrife, saltcedar, Russian olive, yellow starthistle, ventenata, and medusahead rye, among others.
This appendix serves as a reference document for the related solicitation (140P1426Q0068) issued by the Department of the Interior National Park Service Intermountain Region for invasive plant backpack treatments at Grand Teton National Park. The designated weed list establishes the target species that contractors must be capable of identifying and treating during the performance of backpack application work. Contractors responding to the invasive plant treatment solicitation should use this list to understand the scope of plant species they will be expected to manage and to ensure their proposed treatment methods and herbicides are appropriate and effective for controlling these specific Wyoming-designated noxious weeds.
