Invasive Annual Grasses
Sheridan County has recently discovered two invasive annual grasses, Ventenata and Medusahead, that have never been found in Wyoming nor the Great Plains Eco-region. These species are worrisome because they strangle local flora, promote dangerous wildfires, diminish diversity, and reduce wildlife habitat. They have the ability to reduce grazing capacity by 70%. These annual grasses out-compete the native vegetation because they germinate early in the fall and deplete soil nutrients and moisture. They are far more invasive than Cheatgrass and rapidly change native landscapes.
It is very important to notify Sheridan County Weed & Pest of potential sightings.
