About this file
This document is a list of Wyoming State Designated Weeds that serves as a reference attachment for the invasive plant treatment solicitation for Grand Teton National Park. The list categorizes noxious weeds into two primary designations: List A and List B weeds, which represent different levels of regulatory concern and control requirements under Wyoming state law. List A weeds are those that are not widely distributed across the state and are subject to mandatory control and eradication efforts, while List B weeds are more established but still require management to prevent spread and further infestation.
The document provides the scientific and common names for each designated weed species, enabling contractors to accurately identify target plants for treatment during backpack-based invasive plant control operations at Grand Teton National Park. This reference is essential for ensuring that treatment efforts comply with Wyoming state regulations and focus on the appropriate invasive species within the park's boundaries. The list establishes the botanical standards that contractors must use when selecting which plants to target during the invasive plant treatment work.
