Areawide Pest Management (AWPM) is the systematic reduction of a target pest(s) to predetermined levels using uniformly applied pest mitigation measures over geographical areas clearly defined by biologically-based criteria (e.g., pest colonization, dispersal potential). This storymap provides the following: Background, Current Projects, Success Stories, and Data Exploration. The program has six active projects on crops, insects, invasive plants, and agronomic weeds spread across the US. These updates provide a brief summary, current status and projections along with photos and graphs.
Note: Success Stories include The Ecological Areawide Management (TEAM) of Leafy Spurge, Invasive Annual Grasses (cheatgrass medusahead),  Fruit Flies (Mediterranean fruit fly, melon fly, Oriental fruit fly, and Malaysian fruit fly).

ARS scientists in Nevada, studied ways to control cheatgrass and restore rangelands to a healthy mix of plants, which in turn reduces wildfire threats, supports wildlife, and increases sustainable grazing resources.

Fire-friendly grasses have invaded new habitats around the world. Five species (cheatgrass, cogon grass, gamba grass, molasses grass, and buffelgrass) are considered among the most problematic grasses, threatening to transform entire ecosystems.

Cattle grazing on a nearly half mile wide targeted strip of cheatgrass near Beowawe, Nevada, created a firebreak that helped limit a rangeland fire to just 54 acres this past August compared to rangeland fires that more commonly race across thousands of acres of the Great Basin. This "targeted grazing" firebreak and eight others are part of an evaluation project being managed by the Agricultural Research Service (ARS), partnering with other federal, state and local agencies and local cattle ranchers in Idaho, Nevada and Oregon. These demonstration sites are being studied so the concept's efficacy and environmental impacts can be uniformly evaluated and compared.

Cheatgrass, also known as downy brome, is an invasive annual that dominates more than 100 million acres of the Great Basin in the western U.S. Germinating each winter, cheatgrass grows furiously in spring and dies in early summer, leaving the range carpeted in golden dry tinder. The Great Basin now has the nation's highest wildfire risk, and rangeland fires are outpacing forest fires when it comes to acreage destroyed.
