A new publication urges residents to whack invasive weeds before becoming a problem in Wyoming.

Photographs and descriptions of 24 weeds – from purple star thistle to Syrian bean-caper – are listed in the new four-color publication “Wyoming Weed Watchlist Field Guide,” B-1227, from the University of Wyoming Extension.

The publication is designed to enhance prevention and early detection efforts of weeds not yet widely established in Wyoming, said Brian Mealor, extension weed specialist.

“The highest-leverage step in reducing the potential impact of new invasive weeds in Wyoming is to detect new populations beforethey can become well-established,” said Mealor. “Small, new populations are easier to control than larger, older populations.”

Students enrolled in the fall 2010 invasive plant ecology course developed the bulletin, said Mealor, an assistant professor in the Department of Plant Sciences in the College of Agriculture and Natural Resources.
