Dakota County will restore and enhance 225 acres of degraded bluff prairie, savanna, oak woodland, and former crop fields on the east side of Trout Brook in Miesville Ravine Park Reserve. The project area includes approximately 5 acres of remnant dry bedrock bluff prairie, a globally threatened plant community and potential habitat for dozens of rare, declining or vulnerable wildlife species. The remnant bluff prairie is broken up into small pockets and is disappearing due to lack of fire on the landscape which has allowed trees and shrubs to dominate the bluffs.
Traditional restoration methods will be used on moderately sloped segments of this project; however, on about 76 acres of steep sections within the project area, Dakota County will use goat browsing for restoration work.
This restoration project is funded by two grants totaling $800,000 from the Conservation Partners Legacy Program.
Restoration will take place through June 2020. See project map.
The benefits of using goats
Effective at woody brush control
Costs are similar to conventional methods
Reduced usage of chemicals
Sure-footed on steep slopes
Less erosion on steep slopes
Steep slopes restrict use of equipment
Steep slopes unsafe for crew workers
Impact on park users
Areas to be browsed by goats will be surrounded by electric fence. Park users should avoid coming into contact with fence. Signs are posted warning park users of the potential hazard.
