Noxious weeds may be on the land or in the water. These so called, “invasive species” are a continuous threat to the quality of wildlife habitat, the state’s fisheries, Montana’s native plant species and to the aesthetic and recreational value of private and public lands.
Montana Fish Wildlife & Parks is responsible for noxious weed management on about 610 sites across the state and on more than 364,000 acres. In collaboration with other state, federal, county and city entities, FWP uses the latest integrated noxious weed management methods to help protect Montana’s public lands, including herbicide application, mechanical control, targeted grazing, and biological control insects.
Success in controlling noxious weeds and preventing the introduction and spread of new species requires the participation of all Montanans. Please:

The US Forest Service (USFS) considers nonnative, invasive species to be a major threat to National Forests. Noxious weeds are a type of invasive weed that can be harmful to the environment, people, animals, crops, soil and livestock health. They can also alter species diversity, hydrology, nutrient cycling, and natural disturbance patterns, such as the frequency and intensity of wildfires.

For the first time, land managers can compare noxious weed lists from the lower 48 United States and six Canadian provinces by logging on to a new section of the University of Montana’s “Invaders” website. Researchers with USDA’s Agricultural Research Service developed the new noxious weed section at the website. Click here to view the noxious weed information.
The APHIS Federal noxious weed program is designed to prevent the introduction into the United States of nonindigenous invasive plants. APHIS noxious weed activities include exclusion and permitting and (in cooperation with other agencies and state agencies) integrated management of introduced weeds, including biological control.The Weed Program Mission Statement: APHIS will use science-based methods to prevent the introduction of parasitic-plant pests and Federal noxious weeds (including those already regulated and candidates for regulation) into the United States.Biological Control Program Information.

Every day, invasive species are threatening the health of our nation’s vital agricultural and natural lands. Forests and rangelands are being infested, cropland production is being negatively impacted, streams and waterways are being choked with weeds, and wildlife species are losing habitat. These conditions are just a few of the negative impacts that will continue, or will become more severe, if successful actions are not taken to halt and/or reverse this trend.

The BLM was established in 1946, but its roots go back to the years after America’s independence, when the young nation began acquiring additional lands. At first, these lands were used to encourage homesteading and westward migration. The General Land Office was created in 1812 to support this national goal.
Over time, values and attitudes regarding public lands shifted, and President Harry S. Truman, by means of a government reorganization, merged the GLO and another agency, the U.S. Grazing Service, creating the BLM.Explore BLM’s history through stories, video and more.

Montana State University is in a class of its own. MSU is among the top 3% of colleges and universities for research expenditures, and is also classified by the Carnegie Foundation as an institution with a high undergraduate profile. This means that undergraduates at MSU get research opportunities typically reserved for graduate students at other schools. Plus, MSU’s location at the crossroads between Yellowstone National Park and some of the biggest skiing in America offers students a classroom, lab and playground unlike any in the world.
The Department of Land Resources and Environmental Sciences (LRES) at MSU offers a multi-disciplinary approach to understanding and managing land resources. Our coursework and research involves soils, microorganisms, insects, plants, climate, and water; the options within our majors allow undergraduates to focus on their specific areas of interest. We also offer advanced degrees – three M.S. degree programs, and online M.S. degree program, and a Ph.D. program.
