When Is a Bat Emergence & Re-Entry Survey Needed?
A bat emergence and re-entry survey is needed whenever a construction or development project might impact bat habitats. Typically conducted between May and September, these surveys are crucial when planning extensions, demolitions, or developments near known bat roosts.
During these surveys, we use specialised equipment like bat detectors to monitor whether bats emerge from or return to a site, collecting essential data on bat activity and species present. This information can reveal the presence of species under legal protection, such as the common pipistrelle or brown long-eared bats.
Understanding their activity informs necessary mitigations to ensure compliance with conservation laws like the Wildlife and Countryside Act 1981. Besides protecting biodiversity, our surveys help you obtain appropriate planning permissions.
Ensure compliance with environmental regulations and protect biodiversity by organising a survey.
How Does a Bat Emergence & Re-Entry Survey Work?
We conduct surveys using a structured approach:
Initial Assessment: Evaluate the site to identify potential bat roosts. During this phase, we assess buildings, attics, and even tree cavities which may serve as roosting sites for different bat species.
Setting Up Equipment: Position bat detectors and prepare visual observation points. We use full-spectrum bat detectors which capture ultrasonic calls, aiding in species identification. Night-vision equipment may also be used to observe the bats' movements.
Survey Sessions: Monitor bat activity at dusk and dawn for 1 to 2 hours. These sessions are crucial as certain bat species have specific flight times that can indicate their presence.
Data Analysis: Analyse recordings and observations to identify species. We employ software for sound analysis, distinguishing between species like the common pipistrelle and the lesser horseshoe bat.
Report Preparation: Compile findings into a detailed report with recommendations. This report includes habitat suitability assessments and possible mitigation strategies.
Contact us today to book a survey and ensure compliance with wildlife regulations.
How Long Does a Bat Emergence & Re-Entry Survey Take?
Most bat emergence and re-entry surveys take around two to three evenings and mornings to complete. Each session lasts 1 to 2 hours and involves the use of ultrasonic bat detectors, such as the Pettersson D500X or Anabat SD2, to monitor bat activity.
Our surveys adhere to the Bat Conservation Trust (BCT) guidelines, ensuring scientific rigour and reliability.
The total timeline, including data analysis and report writing, can extend to approximately one to two weeks, depending on project size. The analysis process may involve using software like AnalookW to interpret echolocation recordings.
Our reports provide detailed insights into bat species presence, with recommendations for mitigation if required. We can support a variety of property types, from residential renovations to large-scale commercial developments.
If you need a bat survey, contact us to discuss your specific requirements.
Who Needs Bat Emergence & Re-Entry Surveys?
Clients involved in property development, construction, or land management typically require these surveys. This includes architects, developers, local authorities, and conservation groups.
Surveys are often needed during the planning stages of a project to identify bat activity and roosting sites, ensuring compliance with regulatory bodies like Natural England.
These surveys are also crucial when renovating old buildings or barns, as bats may have established roosts in roof spaces or eaves. Projects near woodland, water bodies, or hedgerows, which are common habitats for bats, are particularly likely to necessitate these assessments.
Using techniques such as bat detectors, night-vision equipment, and thermal imaging, we observe bat behaviour during peak activity times, typically between May and September. By following guidelines from the Bat Conservation Trust, we provide accurate data that helps in the development of mitigation strategies, should protected species be present.
How Much Does a Bat Emergence & Re-Entry Survey Cost?
A bat emergence and re-entry survey typically costs between £1,000 and £1,500, depending on site size and complexity. Factors influencing cost include the number of survey visits required, the presence of known roosts, and the need for specialised equipment.
For example, infrared cameras and ultrasonic detectors are often used to accurately track and record bat activity during dusk and dawn.
Surveys are conducted over several nights to ensure comprehensive data collection, often taking two to three visits per site. Another consideration is the seasonal timing: surveys are usually carried out in summer when bats are most active.
