![]() ![]() Henry David Thoreau, Walden Concord and Carlisle have been hosting more than 300 itinerant field workers from August to October: a flock of sheep "hired" to graze several fields owned by these towns, private conservation organizations, and the national park. The goal of their work is to encourage the growth of native grasses, control invasive exotic plant species, revitalize old agricultural fields, and regain historic landscapes.
The sheep will be working each site in small portions to ensure that they eat most of the vegetation to the ground. This type of grazing will encourage grasses and discourage woody plants. They will leave the site a bit brown initially, but quickly the grasses will grow.
The flock and its human and canine attendants were hired from Bellwether Solutions, a Concord, NH company which provides grazing sheep intended to keep land open, an alternative to mowing, pesticides, or cutting of small trees. They have been grazing land beneath power lines in New Hampshire for the past four summers. Snowbirds, they munch kudzu in Florida during the winter. The effectiveness of this technique is still being researched, but it already seem clear that the sheep do a better job of killing small trees than do mowing, pesticides or hand-cutting, especially if they are brought back for a second graze in about a month. Some hope this more environmentally friendly and visually appealing method of maintenance could prove to be more cost-effective in the end. The members of this cooperative pilot project are The Carlisle Conservation Commission, The Carlisle Conservation Foundation, The Concord Land Conservation Trust, The Concord Natural Resources Commission and Minuteman National Historical Park. If you have general questions about this project, contact Markus Pinney or Rachel Landry 318-3285, both of the Concord Natural Resources Commission.
