Tree work and nesting birds
Quick answer: It is an offence to intentionally damage or destroy an active bird's nest. The main nesting season runs roughly from March to August, so check carefully before cutting trees or hedges then. Bats and their roosts are also protected.
Wild birds, their nests, eggs and young are protected by law in the UK. This affects tree surgery and hedge cutting as much as it does building work.
The rule
It is an offence to intentionally damage or destroy an active wild bird's nest. The main nesting season is roughly March to August, though some birds nest earlier or later, so there is no safe date.
What to do
- Plan work for outside the nesting season where you can.
- If you must cut in the season, have the tree or hedge checked carefully for active nests first, by a competent person.
- If you find an active nest, stop and leave it alone until the young have fledged.
Bats
All UK bats and their roosts are protected, even when the bats are not there. If you find bats, or a tree with holes or cavities that could hold them, stop and get advice from a licensed ecologist or the relevant nature conservation body before doing any work.
Good tree surgeons
A responsible tree surgeon will ask about nesting birds and bats and will check before they cut. See how to choose a tree surgeon. For hedges see our hedge trimming guide.
