The Wildlife Trusts manage many woodland nature reserves sympathetically for the benefit of all kinds of wildlife. A mix of coppicing, scrub-cutting, ride maintenance and non-intervention all help woodland wildlife to thrive. You can help too: volunteer for your local Wildlife Trust and you could be involved in everything from traditional forest crafts to surveying for woodland plants.
