When you can, and can't, cut a hedge in Tenterden.

Wildlife & the law · Updated 20 September 2026

This is the single most-asked question I get on the phone, and it's a fair one: nobody wants to accidentally commit a wildlife offence trying to keep their garden tidy. The law itself is simple. Applying it sensibly to a real hedge takes a bit more.

What the Act actually says

Section 1 of the Wildlife and Countryside Act 1981 makes it an offence to intentionally kill, injure or take any wild bird, or to intentionally take, damage or destroy the nest of any wild bird while it's in use or being built. It's an offence regardless of the species, common garden birds are covered exactly the same as rarer ones. There's no exemption for garden maintenance or hedge cutting specifically, the law applies to a domestic hedge trim exactly as it applies to agricultural hedge-cutting or development clearance.

The practical caution window most contractors and gardening authorities use is 1 March to 31 August, covering the bulk of the UK breeding season, with some guidance extending into September to cover late second broods, particularly in a mild autumn. Outside that window, from roughly September through February, most native hedgerow species aren't actively nesting and routine cutting can proceed without a nest check.

Why this matters more here than it might elsewhere

Tenterden and the surrounding Weald villages are built around mixed native hedgerows, hawthorn, blackthorn, holly, field maple, exactly the dense, thorny structure that blackbirds, dunnocks, wrens, robins and yellowhammers favour for nesting. A tidy, actively-managed garden privet hedge is lower nesting risk than an untouched field-boundary hawthorn run that hasn't been cut in a year or two, the latter is far more likely to have an active nest tucked into the base by late spring.

What "intentionally" means in practice

The offence requires intent, or in some readings recklessness, not absolute liability regardless of care taken. In practice, that means: if you inspect a hedge properly before cutting and there's genuinely no visible nest, and something unseen is destroyed anyway, you're in a very different legal position than someone who cuts through an obviously active nest without looking. The safe, sensible approach isn't "hope for the best", it's: don't cut inside the caution window unless you've actually checked, and if you find an active nest, leave that section alone until the young have fledged.

Timing by hedge type

• Formal garden hedges (privet, beech, yew, laurel): lower nesting risk if actively maintained, but still checked in-season as a matter of course.
• Native field-boundary hedgerows (hawthorn, blackthorn): highest nesting risk, especially if left unmanaged over winter. September to February is the strongly preferred window.
• Evergreen screens (holly, Leylandii): dense evergreen cover is attractive to nesting birds year-round in a mild winter, so even an "out of season" cut gets a quick visual check.
