How can people help

The Wildlife Trusts manage many grassland habitats for the benefit of wildlife - careful grazing with traditional breeds and scrub clearance are just a couple of the ways we ensure a balance of plants and cover in these fragile habitats. By volunteering for your local Trust you can help too, and you'll make new friends and learn new skills along the way.
