How can people help

Human activity, including the drainage of land for agriculture, the loss of ponds through development and the removal of wet woods, has resulted in the disappearance of many of the UK's wetlands. The Wildlife Trusts are working closely with planners, developers and farmers to ensure our wetlands are protected. You can help by becoming a member of your local Trust; you'll find out about exciting wildlife happenings, events on your doorstep and volunteering opportunities, and be helping local wildlife along the way.
