Project Description:
(Up to 250 words)
Invasive woody vegetation degrades grassland and oak savanna habitat for migratory birds dependent on these habitat types. Native prairie and oak savanna are two of the most rare habitat types in Minnesota. This project will result in removal of invasive woody vegetation on approximately 100 acres of grassland and 5 acres of oak savanna on the Weber WPA. In 2007 Boy Scout Troop 224 of Willmar, Minnesota participated in this grant program and removed invasive woody vegetation from 70 acres of grassland and portions of 5 acre oak savanna on the Weber WPA. Much of the oak savanna on this WPA was heavily invaded by boxelder and green ash trees that were too large (1 to 2 foot diameter) for the Scouts to safely cut and fell. In February of 2008 Litchfield staff cut down all of the large invasive trees. This has resulted in an impenetrable tangled area of felled trees. This year’s proposal includs hiring a contractor with a portion of the grant funds to remove, via use of a skidder, the felled trees so that the Scouts can access the area and remove the remaining smaller trees such as buckthorn, box elder, and prickly ash; seed the area to native grasses and forbs; plant young bur oak trees; recon the grassland area restored last year to remove any woody vegetation that was missed or resprouted; and remove woody vegetation from 30 additional acres of prairie located on other portions of the WPA. Remaining piles of woody debris will be burned by Service personnel under prescribed fire operations or be used as biofuels.

Describe the type of work the volunteers performed. (Up to 150 words)
Work consisted primarily of pulling buckthorn and honey suckle from a native oak stand. Larger specimens were cut and treated with herbicide. Literally thousands of buckthorn were pulled by hand. A total of 5 acres were cleared using these methods. Additionally, invading woody species were controlled by cutting and spraying on approximately 45 acres of grassland not treated in 2007 and on 70 acres of grassland that ws treated in 2007. Due to the density of invasives removed in the woodland and woodland edge site, a great deal of bare ground was exposed. This area was seeded to a native ecotype mixed hieght mesic and savanna mix consisting of 13 sp. of grasses and 52 sp. of wildflowers. Seven bur oaks were also planted.

The project was accomplished almost exclusively by Boy Scout Troop 224 of Willmar, Mn. Parents and siblings of the Scouts also participated.


Project Results:
Give an overview of the results of the project. Include quantifiable measure of success, such as maps produced, efficacy of control measures, number of sites where invasions were detected early and responded to, number of community contacts, etc. (Up to 250 words).
Five acres within and around two native stands of oaks were cleared of invading trees. Large green ash and boxelder trees were removed and piled by a contractor and smaller trees consisting primarily of buckthorn, honey suckle, green ash and boxelder were removed by volunteers. Two acres were hand seeded to native ecotype grasses and wildflowers and 7 bur oak were planted to restore a 1/2 acre to oak savanna. One hundred and fifteen acres of exisiting grassland of which 30 acres was native prairie was treated by removing all woody plants. Seventy of the acres had been treated last year and 45 acres including the native prairie were treated for the first time this year.
Number of Acres Treated: 120
Number of Acres Inventoried and/or Mapped: 0
Number of Acres Restored: 120


Budget: Account for funds in broad categories such as equipment, volunteer stipends, travel, coordinator salary/contract, etc.
