Results and Accomplishments
Knife River Indian Villages National Historic Site
The Knife River Indian Villages National Historic Site was dominated by three exotic plants, smooth brome, crested wheatgrass and Kentucky bluegrass. The site was prepared for reseeding to native species with a prescribed fire in April of 2004. The fire was followed by two herbicide applications in May and September 2004, with some areas retreated in May of the 2005. By June 2005, over 110 acres were seeded with a mixture of native grasses, forbs. In order to ensure establishment of the native plant community these areas will be hayed in 2006, 2007 and 2008. Prescribed fire will be used periodically to maintain and favor native species. Park Superintendent Cheryl Schreier has said, “This project is a tremendous accomplishment that will provide visitors with a more accurate presentation of
Knife River ’s 19th century landscape.”
The Northern Great Plains Exotic Plant Management Team, Montana Conservation Corp and Theodore Roosevelt Resource Management personnel teamed up to treat 374 acres of leafy spurge along the Little Missouri River. Furthermore, the Northern Great Plains Exotic Plant Management Team was able to collect and release nearly 10 million biological control agents to aid in the control of leafy spurge.
The cooperative efforts were supplemented with aerial treatments; 331 acres of Canada thistle and 620 acres of leafy spurge were treated.
