British Woodland Survey

The purpose of the Woodland Survey is to understand the causes and consequences of change in woodlands across Great Britain since 1971, focusing mainly on ancient broad-leaved woods and Caledonian pine-woods. Such ancient woodlands contribute to essential ecosystem services such as carbon storage, flood control, providing nectar for insect pollinators of crops, and recreation. They also provide a vital refuge for many threatened species now rare or absent from other habitats and land modified by human activity.
