Woodland and blanket tree preservation orders in practice

A woodland tree preservation order protects every tree within the mapped area, including trees that germinate after the order was made. An area order protects only the trees of the specified kind that stood within the mapped area on the day the order took effect, and nothing that has grown since. Those two classifications look almost identical on a constraints plan and they behave completely differently on site, which is why so many owners are surprised by what they can and cannot fell.

The Town and Country Planning (Tree Preservation) (England) Regulations 2012 set out the standard form order, and the classification used in each order is stated in the schedule to it. Read the order, not the constraints layer.

The four classifications used in an order

The standard order schedule lists trees under four headings, and each carries a different scope.

Individual trees, prefixed T in the schedule, are identified singly by species and position. What is protected is that tree. Cut it down unlawfully and there is nothing left for the order to protect.

Groups, prefixed G, protect a stated number of trees of stated species within a defined group. The group is protected as an entity, which has consequences if one member dies.

Woodlands, prefixed W, protect all trees within the mapped woodland, of whatever species, including natural regeneration and replanting after the order date. This is the only classification with a forward-looking effect.

Areas, prefixed A, protect the trees of the specified kind standing within the mapped area at the date the order was made. It is a snapshot, and the snapshot ages.

What a woodland classification covers

Because a woodland order captures future trees, it is the right tool for a working or regenerating wood and the wrong tool for a group of specimen trees in a garden.

Practically, it means a self-seeded sycamore that appeared ten years after the order is as protected as the oaks that prompted it. Owners clearing scrub within a woodland order frequently commit an offence without realising, because the vegetation they are clearing has become trees.

Woodland management is not prohibited, but it does need consent or an exemption. Thinning, coppicing and felling within a woodland order are dealt with either by an application to the authority or, where the volumes reach the relevant threshold, by a felling licence from the Forestry Commission. Where a felling licence is granted, separate consent under the order is not required, which makes the licence route the sensible one for genuine woodland operations.

For a wood under active management, an approved management plan is the cleanest arrangement, because it covers a programme of operations rather than requiring an application each season.

Area orders and their historic quirks

Area classifications were used heavily from the 1950s to the 1980s as a quick way to protect everything on a site while a proper survey was done. The survey often never happened.

Government guidance has for years discouraged new area classifications and encouraged authorities to re-survey and replace them with individual, group or woodland classifications. Many have. Many have not, and a 1974 area order is still in force over plenty of sites.

The difficulty with an old area order is evidential. It protects the trees of the specified kind that were there on the order date. Establishing which of today's trees were standing fifty years ago means comparing aerial photography from around the order date with the current position, and assessing the age of individual trees.

That is work for an arboriculturist, and it needs doing before a chainsaw is booked rather than afterwards. Where the evidence is unclear, treat the tree as protected and apply.

Checking which trees an old order actually protects

Work through this sequence:

1. Ask the council for a copy of the order, its schedule and its map, and check whether it has been confirmed and whether it has been amended.
2. Read the classification letter against each entry in the schedule, since one order can contain entries of several kinds.
3. Compare the order map with the current site plan, because boundaries shift and mapping was imprecise.
4. For an area order, obtain aerial imagery from around the order date and compare canopy extents.
5. Commission a survey to BS 5837:2012 recording species, age class, condition and category for each tree.
6. Confirm the conservation area position separately, because trees in a conservation area carry their own notification requirement whether or not an order applies.

A Tree Survey prepared to the British Standard is the document that turns all of that into something a council will engage with, and councils expect a suitably qualified author with professional review strongly advised. The wider pre-purchase exercise is covered in our note on checking a site for constraints before you make an offer.

Applying for consent and the exemptions

Applications for consent to carry out work to protected trees are made to the local planning authority, carry no fee, and are normally determined within eight weeks. A refusal can be appealed to the Planning Inspectorate.

The exemptions in the legislation and the Regulations are narrower than most people assume. The main ones cover dead trees, trees that are dying or have become dangerous, work necessary to prevent or abate a nuisance, work required to implement a full planning permission, and certain statutory undertaker operations.

The nuisance exemption is the most abused. It is a legal test about actual or imminent nuisance, not a general licence to cut back a tree that drops leaves on a drive.

Dead, dying and dangerous trees

The emergency exemptions exist for real emergencies, and the evidential burden sits with the person who cut the tree down.

Before relying on one, photograph the tree from several angles, record the date, obtain a written opinion from an arboriculturist where time allows, and give the council the notice the Regulations require. Five working days is short, and it is far cheaper than defending a prosecution.

Penalties are serious. Cutting down, uprooting or wilfully destroying a protected tree, or damaging it in a manner likely to destroy it, is an offence carrying an unlimited fine on conviction in the Crown Court, and the value of the development the tree was standing in the way of is a relevant consideration for the court.

Replacement duties after removal

Where a protected tree is removed in contravention of an order, or under the dead or dangerous exemptions, a duty to plant a replacement arises under the Town and Country Planning Act 1990. In a woodland the duty is to replace the trees in accordance with relevant forestry practice rather than tree for tree in the same spot.

The duty attaches to the land and passes to a subsequent owner. An authority can enforce it by serving a tree replacement notice within a period running from when the breach came to its knowledge, and the replacement tree becomes protected by the original order.

Plan for it. On a site where tree loss is proposed as part of a scheme, deal with replacement planting properly in a Landscape Strategy rather than leaving it to a notice, and consider how the planting contributes to wider green infrastructure, a point covered in our note on green corridors and connectivity policy in local plans.

Illustrative example: a 1970s area order over a half-hectare plot bought for two new houses. The survey finds 34 trees. Aerial photography from the order date shows canopy over roughly a third of the plot. Seven trees can be shown on age and position to predate the order and are protected. The rest are not, though several are worth keeping on amenity grounds and the scheme is designed around them anyway.

This is general guidance, not legal advice; check the position with your local planning authority or a qualified arboriculturist before relying on it.
