Dormouse surveys / other small mammals

Bat

Dormice are fully protected under the Wildlife and Countryside Act 1981 (as amended) and the Conservation of Habitats and Species Regulations 2010 such that it is an offence, amongst other things to: i) deliberately capture, kill or injure any Dormouse; ii) damage or destroy a breeding site or resting place used by Dormice (whether they are in it at the time or not); iii) deliberately disturb Dormice in a way that is likely to impair their ability to hibernate, survive or reproduce, or in a way that is likely to affect significantly their local distribution or abundance; iv) intentionally or recklessly disturb Dormice while occupying a place of shelter or protection, or attempt to do so; v) intentionally or recklessly obstruct access to any place of shelter or protection, or attempt to do so.

Where suitable Dormouse habitat is confirmed on a site that is affected by development plans, during an EECOS Preliminary Ecological Appraisal / Phase 1 survey or by other means, then further specialised survey work may be required to determine their presence or absence. A Dormouse survey would normally involve placing nest tubes throughout the suitable habitat and leaving them there for a whole season. They are then checked under licence from Natural England to see if the tubes have been used by nesting Dormice.

Survey results will be presented in a full written report that also includes an impact assessment and recommendations for impact avoidance measures or, if necessary, licensing.

EECOS is also able to carry out general surveys of small mammals to assess species diversity and population size, using Longworth live traps set out in grid patterns over a period of several days.
