Bat Survey Dorset: Protected Species

A bat survey, Dorset may be required to uphold necessary ecological commitments which apply to new project developments in and around the area. Supporting the preservation of bat habitats and roost sites is crucial for local councils with the aim of mitigating risk factors to bats alongside other endangered species. Collington Winter Environmental have a team of experienced ecologists who are willing to provide assistance when undertaking any bat surveys, Dorset.

Local planning authorities typically review planning applications and perform inspections before and during construction work takes place. This way, the council can ensure ecological requirements are attended to. Supported by important legislation such as The Wildlife and Countryside Act 1981 and The Conservation of Habitats and Species Regulations 2017, Dorset Council may delay or even prevent a project from receiving permission if they believe mitigation for any  protected species has been neglected.

If a survey has recorded the bat presence, a duty of care is bestowed upon project developers to prevent the bats from experiencing any harm or disruption. Strategic measures must be put in place to prevent further decline of bat species across the UK, including Dorset.

A bat survey process will typically follow a structure similar to the one below and will inform a bat mitigation strategy:

• Preliminary Roost Assessment (PRA): This initial survey determines whether bats are likely to be roosting in a building or structure. It is an important first step in evaluating the potential impact of the proposed development on local bat species. Consultants will inspect both the internal and external areas of a site for any evidence of bat roosts, such as bat droppings.
• Bat Emergence Surveys and Re-entry Surveys: If bat activity is detected after the preliminary survey, an emergence or re-entry survey may be necessary. These surveys track bat movements, including entry and exit points to buildings, providing valuable insights into bat behaviour, roosting locations, and feeding habits. They are typically conducted multiple times, both day and night, using equipment like thermal imaging cameras and automated bat detectors to minimise any disturbance to the bats.
• Nocturnal Bat Surveys: Since all UK bat species are nocturnal and use echolocation, nocturnal surveys are an effective way to monitor their activity and behaviour. These surveys are typically performed at night to gather detailed data on bat behaviour and activity levels.

For any surveys conducted, a list of recommendations will be presented to a project manager on how best to support any present bat species and habitats. This can include physical provisions to protect or replicate bat roosting spots and inform a works schedule to prevent unnecessary disturbance of the bats.
