How people can help

The Wildlife Trusts manage many grassland and coastal habitats sympathetically for the benefit of all kinds of wildlife. Careful grazing with traditional breeds, hay-cutting at the right time and scrub clearance are just some of the ways these habitats are kept in good condition. By volunteering for your local Trust you can help too, and you'll make new friends and learn new skills along the way.
