Threats from human impact

The UK’s woodland is under threat. More than 1,000 irreplaceable ancient woods have been threatened by development over the last 10 years.

Development can impact ancient woodland in a number of ways, through chemical pollution, disturbance, fragmentation and the introduction on non-native plants, as well as cumulative effects.

We work with developers to provide advice on protecting woodland and in some cases we campaign to prevent any further loss of ancient woodland to development.

We also work with government, landowners, organisations and members of the public, using our experience and authority in conservation, to campaign for protection of woods and trees.
