Hedgerow Rules for Dorset Landowners: Cutting Dates, Nesting Birds and the Law
2026-08-26 · Heartwood Tree Management

Hedges sit under more legislation than almost any other garden or farm feature, nesting bird protection, cross-compliance cutting windows, and the Hedgerow Regulations for removal. Here's the working version.
The nesting season rule (everyone)
All wild birds, their nests and eggs are protected under the Wildlife and Countryside Act. The main nesting season runs roughly March to August. Cutting a hedge with an active nest in it is an offence, so professional practice is to plan hedge work outside that window, and where summer cutting is unavoidable, to check thoroughly first and stop if a nest is found.
The farmland rule (agricultural land)
On or next to land used for agriculture, hedgerows must not be cut or trimmed between 1 March and 31 August under the Management of Hedgerows (England) Regulations, in force since 23 May 2024. The exemptions are specific: a hedge overhanging a highway or footpath; one that is dead, diseased or insecurely rooted and likely to fall onto a road; hedge-laying or coppicing between 1 March and 30 April; a genuine risk to health or safety; cutting in August ahead of sowing oilseed rape or temporary grass, which must be notified to the Rural Payments Agency first; and written derogations from the RPA. Under any exemption you may only cut the part of the hedge it covers, you must keep a record, and nesting birds remain protected. Private garden boundaries are outside these rules but not outside the Wildlife and Countryside Act. Current guidance: gov.uk hedgerow management rules. Practically: farm hedges are a September-to-February job, and the best-managed ones are cut on a two- or three-year rotation rather than annually, better for berries, wildlife and the hedge itself.
Removing a hedge is a different question
Countryside hedgerows over 20m long generally fall under the Hedgerow Regulations 1997: you must notify the council before removal, and "important" hedgerows (old, species-rich, historically significant) can be protected outright. Ripping one out without checking can mean being ordered to replant it.
Reductions, laying and restoration
An overgrown hedge doesn't need removing, it needs renovating. Hard reductions staged over two seasons, or traditional laying, turn a gappy tunnel of leylandii or hawthorn back into a dense, stock-proof, wildlife-rich boundary.
