The Wyoming Weed Watchlist Field Guide is designed to enhance prevention and early detection efforts of weeds not yet widely established in Wyoming. It was developed by students enrolled in the University of Wyoming's Invasive Plant Ecology course of fall semester 2010. The field guide is not intended as a management handbook, but rather an educational tool for outdoor recreationalists, natural resource professionals, tourists, gardeners, agriculturalists, and others to aid in identification of unfamiliar, yet extremely important, weeds in the region. The highest leverage step in reducing potential impact of new invasive weeds in Wyoming is to detect new populations before they can become well established.

The yellow-legged hornet was first detected in the U.S. when a beekeeper close to Savannah, GA, found an unusual hornet on his property and reported it to the Georgia Department of Agriculture (GDA). On August 9, 2023, APHIS confirmed the University of Georgia’s identification of this insect as a yellow-legged hornet.
