Bat Survey Season: April – September
The bat survey season began in April and runs until September, during which time bats are dependably active, engaged in foraging and breeding activity. Outside of this period, bats are gearing up for hibernation over the winter and activity surveys are not possible. Hence, to avoid delays to your schedule it’s important to plan for the bat survey season early as part of the planning and development process by getting an ecological consultancy involved early.
Protected species – bats & the law
There are 18 species of bat living in the UK (17 of which are breeding). All are fully protected by law under the Conservation of Habitats and Species Regulations 2010 and the Wildlife and Countryside Act 1981. It is illegal to injure, kill, capture or disturb a bat or to damage, destroy or obstruct trees, buildings or other places used for roosting.
Our fast and effective bat surveys & bat mitigation
Our licensed bat specialists and experienced surveyors will typically conduct an initial assessment to identify the potential for bats to be using a site. Follow-up bat surveys to determine the nature of the use of the site for roosting and/or foraging and commuting bats may also need to be undertaken.
Where there is an identified need for mitigation, either as part of a European Protected Species Mitigation (EPSM) licence or a Precautionary Method of Working, we have highly experienced ecologists at hand to advise and support at all stages. This includes preparing licence applications to Natural England and overseeing and implementing all mitigation works.
Our bat survey and bat mitigation services include
- Year-round internal and external building inspections (preliminary roost assessments) for bats
- Dusk bat emergence and dawn re-entry surveys during bat survey season (roost characterisation surveys – optimal survey period May to August)
- Bat activity transects suring bat survey season (optimal survey period April to September)
- Bat hibernation surveys during the winter months
- Design and implementation of bat mitigation measures
- Preparation and submission of EPSM licences to Natural England
- Bat Low Impact Class Licence (BLICL)
