Bats factors to consider l.jpg
Bats - factors to consider

  • National distribution

  • Summer (maternity) roosts

  • Winter (hibernation) roosts

  • Utilise trees, buildings and underground structures

  • Woodland types used

  • How to survey

  • Woodland design (e.g. roost isolation, foraging areas)


Bats potential confirmed roosts l.jpg
Bats - potential & confirmed roosts

Potential roost:

A habitat feature that the surveyor has identified that could offer opportunities for roosting bats.

If only a few potential roosts were identified in the wood, they should not be felled and buffer trees left around them.

Confirmed roost:

Bats are known to be (or have been) entering/exiting this structure. It therefore has legal protection and should be retained undisturbed, with an appropriate buffer of trees.


Bats good practice l.jpg
Bats - good practice

  • Ensure protection of confirmed roosts and their buffer.

  • Where there are few potential roosts, treat as above. Where numerous, a small proportion can be felled in 10yr period.

  • Natural reserves/undisturbed areas.

  • Encourage insect-rich habitat (understorey, rides, ponds).

  • Avoid disturbance of roosts by fire/smoke or excessive noise and vibration.

  • Creation / maintenance of infrastructure.


Otters factors to consider l.jpg
Otters - factors to consider

  • National distribution

  • Catchments & range

  • Holts

  • Woodland types used

  • How to survey

  • Foraging area / quality


Otters good practice l.jpg
Otters - good practice

  • Identify and protect likely holt sites. Avoid mechanised activities within 50m of such resting places.

  • Riparian corridors - within 50m of a watercourse consider the risks of disturbing otters. Phase felling/thinning operations in this corridor over several years to reduce disturbance.

  • Extraction & stacking - where possible, away from riparian corridor.

  • Site preparation - brash treatment & fencing.

  • Sediment run-off.

  • Other possible disturbance - recreation or livestock.

  • Infrastructure.


Dormice factors to consider l.jpg
Dormice - factors to consider

  • National distribution

  • Summer & winter nests

  • Woodland types used

  • How to survey


Dormice good practice l.jpg
Dormice - good practice

  • Avoid woodland management in favourable dormouse habitat from June to mid-August.

  • Clearfell - up to 1/3 of dormouse habitat in the wood, leaving remaining areas undisturbed for 5+yrs.

  • Thinning - up to 2/3 of dormouse habitat in the wood, leaving remaining areas undisturbed for several yrs.

  • Coppice -Up to 25% of habitat in one year.

  • Felling/extraction methods.

  • Site preparation.

  • Mowing, swiping, flailing & scrub cutting.

  • Creation / maintenance of infrastructure.

Great crested newts good practice l.jpg
Great Crested Newts - good practice

  • Within 100m of a breeding pond, phases any significant operations such that only 25% of area is disturbed in any one yr.

  • Try to avoid stacking within 100m of pond.

  • Extraction methods.

  • Site preparation.

  • Mowing regimes.

  • Creation / maintenance of infrastructure.

  • Identify and protect foci

  • Avoid felling, extraction and stacking within 30m of foci

  • Site preparation - brash treatment, spraying and planting

  • Mowing & swiping

  • Other disturbance - including grazing or livestock grazing

  • Creation / maintenance of infrastructure
