  • Noxious Weeds and the Environment: A Bigger Picture

    Karen Laitala, Powell County Weed District|Updated Apr 6, 2021

    Although anyone who knows me knows that I'm a "certifiable" botany and native plants nerd, I love everything nature. In particular, I share a love of birds with one of my sisters. On a trip together one October, we went to a wild bird rescue facility (Vermont Institute of Natural Science) to attend one program, and ended up staying all day, much to our mutual delight.

Poison hemlock, the most toxic of the two, was used to create the potion Socrates was forced to drink in 329 B.C. Some Native...

    Karen Laitala, Powell County Weed District|Updated Jul 23, 2019

    Noxious weeds have destructive impacts on Montana's landscape including displacing native plant species, increasing soil erosion, and decreasing wildlife habitat and recreational opportunities. Rangeland, pastureland, cropland, forests, and wildlands comprise 92 million acres, or 98 percent, of the total land area in Montana. Both new and continued infestations of these non-native species not only reduce the productivity of cropland and rangeland, but infestations of noxious w...
