Field trials were conducted in 2007 on a crown vetch infestation located on Boomerang Island in the Upper Mississippi River National Wildlife and Fish Refuge in Wisconsin.Read More
Studies were initiated by the University of Hawai’i Cooperative Extension Service Invasive Weed Management Program to find a method to improve individual plant herbicide application techniques and determine efficacy of various herbicides applied as undiluted formulations.
In 2009 a coalition of concerned individuals and agencies took action to restore about 175 miles of riparian habitat along the Dolores River between McPhee Reservoir and its confluence with the Colorado River just north of Moab, Utah.Read More
Along the Colorado River near Grand Junction, a group of river guides, biologists, concerned citizens, and conservationists gather for an annual float trip to observe riparian restoration efforts. Rusty Lloyd, program director for the Tamarisk Coalition, and others in this group share concerns about the health of the Colorado and other rivers in the West.Read More
The Little Wolf Fire began in August of 1994, burning over 15,000 acres of national forest and private timber lands in northwestern Montana. Open sites created by the burn and disturbance from fire-fighting activities provided ideal habitat for tansy ragwort. The County Weed District and other partners organized a cooperative weed management area (CWMA) and developed management plans to contain tansy ragwort.Read More
Researchers conducted a study near Matlock, Washington investigating the potential of logging debris and herbicide combinations to inhibit germination and development of Scotch broom (Cytisus scoparius) seedlings. The study site was a mature Douglas-fir forest that was scheduled for harvest. The forest understory included occasional Scotch broom plants that invaded from a previous disturbance, indicating the likely presence of soil-stored seed.Read More
More than 90 volunteers gathered in July to be trained on noxious weed identification, monitoring and control in Glacier National Park as part of the Weed BioBlitz. Participants included volunteer youth and adults from Montana, Wyoming and Idaho.Read More
Chris Hitzeman, a farmer and owner of U-Guide South Dakota Pheasant Hunting, gathered the group to discuss the challenges and benefits of restoring wildlife habitat. This diverse collection of individuals shares an interest in expanding and improving habitat for wildlife in the prairie region.Read More
Researchers at Southern Illinois University conducted a study on sericea lespedeza in the Crab Orchard National Wildlife Refuge. The goal of the research was to explore a comprehensive approach to reducing the abundance of sericea lespedeza by: 1) measuring the level of sericea lespedeza control and forb tolerance to varying rates of herbicides applied in spring and summer, 2) comparing effectiveness of summer-applied to spring-applied herbicide treatments, and 3) determining how supplemental seeding of native grasses and forbs enhance restoration success following herbicide treatment.Read More
The restored prairies and woodlands within Belwin Conservancy also serve as models for ecological restoration in the St. Croix Valley. Non-native invasive plants such as Canada thistle (Cirsium arvense L.) have historically been problematic in prairie restorations. However, a new invader, Grecian foxglove (Digitalis lanata) is impacting desirable plant communities especially on prairie sites.Read More
THE RUGGED LANDSCAPE OF THE DAKOTA PRAIRIE NATIONAL GRASSLAND stretches over 1.2 million acres in two states. These grasslands support a diversity of uses including livestock grazing, wildlife habitat, paleontological and archeological digs, oil and gas production, and recreation.Read More
Purple starthistle (Centaurea calcitrapa) is established in at least 14 states in the U.S., but recently expanded its range to Twin Falls County, Idaho. A quick response from the land owner, field inspector, county weed coordinator, and Idaho State Department of Agriculture is stopping the weed in its tracks.Read More
FREMONT COUNTY WEED AND PEST CONTROL DISTRICT AND THE U.S. BUREAU OF LAND MANAGEMENT (BLM) TEAMED UP WITH THE WYOMING GAME AND FISH DEPARTMENT
and others to keep invasive plants out of greater sage-grouse (Centrocercus urophasianus) habitat.
The Ruby Valley Stock Association and partners organized the Upper Ruby Watershed Cooperative Weed Management Area. Their management goal of ‘healthy lands’ has led to a reduction in weed establishment and spread, stabilized stream banks, increased aspen regeneration, and reduced sediment into the Ruby River.Read More
