Throughout 2013 you may notice large-scale restoration work in Greene Prairie and the Grady oak savannas. The Arboretum has hired Quercus Land Stewardship Services LLC to remove trees and shrubs that have invaded the restorations. You may see a forestry mower grinding up trees up to 4 inches in diameter and clearing large buckthorn, honeysuckle, dogwood and sumac. Quercus staff will follow up the mowing with herbicide treatments. They will also control oriental bittersweet and black locust using cutting and/or herbicide. Trees larger than 4” will be selectively removed using chainsaws. Reducing the invading woody species should increase the diversity and blooming of prairie and savanna wildflowers and grasses. The Friends of the Arboretum procured the funds for this project through a Dane County Partners for Recreation and Conservation (PARC) grant. This grant also provided the funds for the new fence and entrance on the southeast corner of the Grady Tract. To see a video of a brush mower in action, go to our Facebook page.facebook.
