Management and Ecology of Invasive Plant Species
Invasive plants are non-native species that can thrive in areas beyond their
natural range of dispersal. These plants are characteristically adaptable,
aggressive, and have a high reproductive capacity. Their vigor, combined with a
lack of natural enemies, often leads to outbreak populations. These invasive
plant species have become a threat to Montana’s range natural resources. They
are reducing the productivity of our rangelands, the economic vitality of our
ranches, the habitat our wildlife depend upon, and the quality and quantity of
our waters.
According to the Montana Weed Control Association, knapweed and leafy spurge
— just two of the 27 weeds currently listed as a “Noxious Weed” by the state —
have established themselves in every county since first being sighted in 1925.
Other species may prove even more difficult to contain.
Since no single noxious weed treatment works in every situation, the best
results are obtained using site-specific, integrated methods that take into
account how the land will be used. The key to invasive species control is
to understand your specific situation. There is not a boiler-plate solution to
weeds, even to the same weeds. In eastern Montana, which is still relatively
weed-free, efforts can focus on weed prevention. In western Montana, where weeds
have already spread, the focus must be on management and minimizing spread.
NRCS Technical Resources

Additional information is available from NRCS at your
local USDA Service Center.
NRCS Conservation Programs
Land owners and land managers interested in controlling invasive plant
species on their land may be eligible for technical and financial assistance
through the NRCS conservation programs listed here.
- Conservation Security Program (CSP). The
Conservation Security Program is a program that rewards conservation
stewardship. Current weed control management would be one of the criteria
for eligibility into the program. Once in the program, the contract holder
would be eligible to receive enhancement payments for implementation of
innovative and more complex weed management activities, such as reduction of
pesticidal spray overlap through technology, precision application of
pesticides, and implementation of an annual weed scouting program on
rangeland.
For more information: Conservation
Security Program (CSP)
- Environmental Quality Incentives Program (EQIP). The
Environmental Quality Incentives Program is available to those who qualify
as agricultural producers. It is a voluntary conservation program for
farmers and ranchers that promotes agricultural production and environmental
quality as compatible national goals. EQIP offers financial and technical
help to assist eligible participants install or implement structural and
management practices on eligible agricultural land.
For more information: Environmental
Quality Incentives Program (EQIP)
- Wildlife Habitat Incentives Program (WHIP). The Wildlife Habitat Incentives Program is a voluntary program for people who
want to develop and improve wildlife habitat primarily on private land. Through
WHIP, NRCS provides both technical assistance and up to 75 percent cost-share
assistance to establish and improve fish and wildlife habitat. WHIP agreements
between NRCS and the participant generally last from 5 to 10 years from the date
the agreement is signed.
