Advice to help you use this item

Locating boxes for different species

Boxes for all species should be kept in their original location if they’re being used. If they are not being used after year 3, ask Natural England for relocation advice.

Strap boxes should be strapped to trees with wire and hose or rubber to prevent tree damage.

Dormice boxes

Boxes should be:

• in ancient woodlands or large hedgerows – avoid isolated trees
• in batches of at least 10 (ideally over 50), spaced 10 metres (m) to 20m with around 30 boxes per hectare
• 1.5m to 2m above the ground (over 3m if the public have access)
• away from footpaths
• made of untreated timber
• based on the Peoples’ Trust for Endangered Species box construction guidance

Tree sparrow boxes

Boxes should be:

• in farm buildings or hedgerow trees, ideally near permanent water such as ponds or ditches
• away from bird feeders or places cats and squirrels can easily access, with a secure lid
• out of the sun for at least part of the day
• preservative-free if made of wood
• weatherproof with small drainage holes in the floor
• made from wood at least 15 millimetres (mm) thick with a 28mm entrance hole – follow the RSPB and British Trust for Ornithology guidance

Bat boxes

Boxes should be:

• large enough for a maternity colony to cluster to conserve heat
• dry, rainproof and draught-free, with no gaps where the sides and top join
• entered by a slit at the base (front or back) no more than 15mm to 20mm wide – follow the Bat Conservation Trust guidance
• sheltered from strong winds and sun for at least part of day
• close to a hedgerow or tree line
• placed with the boxes facing in different directions to offer a range of temperature conditions

Protected species

Bats and their roosts are protected under the Wildlife and Countryside Act 1981. It’s an offence to disturb, handle or kill bats. A licence from Natural England is needed to inspect bat boxes that have been or are being used by bats.
