Why Should I Care

This 22-page brochure is an excellent resource for land managers regarding invasive weeds and why you should care as a landowner, recreationist or if you like to hunt and fish. It has many simple quick descriptions and photos of some of Montana’s noxious weeds, but more importantly, it simply explains why you should care about this issue. As of July 1, 2025, MWCA is working on producing a reprint of this popular publication. More information TBA.

MWCA Scenic Calendar

Since 2010 the MWCA has been producing a scenic calendar with educational information about noxious weeds in the side bars. The size of the calendar is 9 x 12 inches closed and 12 x 18 inches open. The pictures in this calendar have been outstanding and are submitted each year by MWCA members from all over the state. Many of Montana’s county weed coordinators purchase this calendar to give out to their constituents free of charge. Otherwise we offer this calendar for sale at $5 each for members or $10 for nonmembers. For bulk orders, please contact Becky at mwca@mtweed.org.

MWCA Weed Times Magazine

MWCA produces a digital magazine four times a year for members. This magazine is filled with the latest research, news and information in noxious weed management. This year’s first issue was printed and given to all weed managers in our database and is available below. Future Weed Times will only be sent to the current membership.
