Montana Department of Agriculture Montana has 36 state listed noxious weed species that collaboratively affect about 8.2 million acres of Big Sky Country. Both new and continued infestations of these non-native species not only reduce the productivity of cropland and rangeland, infestations of noxious weeds diminish the productivity and biological diversity of ecosystems by negatively impacting wildlife habitat and by affecting the vitality and survival of native species due to competition for space, nutrients and water.
