Protect Riparian Areas Logo

Riparian areas in semi-arid grasslands are vulnerable to weed invasion. Weed seeds are transported by water from upstream areas to new sites with favorable conditions resulting from the natural disturbance associated with spring flooding. Rivers and streams can be corridors of invasion whereby infested waterways act as source populations for the invasion of upland sites. Land managers should anticipate invasion of riparian areas and frequently monitor these sites for quick detection and removal of new invasions.

Attention All Hunters Logo

A series of eastern Montana newspapers run this ad each fall to encourage hunters to call local weed districts if they find spotted knapweed. This example is for Blaine County.
