Heathland: The constant battle and how you can help The habitat of heathland is not a stable one. Left unmanaged, trees quickly become established and soon form dense patches of scrub, shading out the heathers and gorse below them. In just a few years, what was once a good site for Dartford Warblers can become a patch of secondary woodland. Many heathland reserves rely on volunteer work parties to help them manage the heath, to keep it in tip-top condition for the wildlife that lives there. Speaking as someone who was a ranger for 20 years, I can happily state that volunteers are vital in maintaining many areas of habitat across the country. If you are able to, why not contact your local country park/reserve/wildlife Trust etc to see if they run volunteer parties that you can help with. It is a great way to help maintain an important habitat and to stay fit at the same time. Just think how rewarding it would be to see a Dartford Warbler feeding its newly fledged young on some heathland that you help to manage.
