Hedgerow Rules for Dorset Landowners: Cutting Dates, Nesting Birds and the Law

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 agricultural land, hedge cutting is restricted between 1 March and 31 August under management rules, with limited exceptions (safety, sightlines at accesses). 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.
