Bat Survey Portsmouth: Protected Species Surveys

A bat survey, Portsmouth, may be necessary to meet ecological requirements for new project developments in and around the area. Ecological survey requirements for new sites are often in accordance with local planning regulations. Therefore, bat surveys are a necessary step to determine whether bats may be present on development sites based in the city of Portsmouth.

Working to protect bat habitats and roosting sites is a priority for local councils to minimise risks to bats and other endangered species. Collington Winter Environmental has a team of skilled ecologists ready to provide the efficient ecological services that your development proposal needs.

Due to important legislation, such as The Wildlife and Countryside Act 1981 and The Conservation of Habitats and Species Regulations 2017, a local planning authority may be obliged to intervene with a project if they believe bats could be present and actions to protect them have been neglected.

Bat activity surveys on development sites in Portsmouth should be conducted between May and September, aligning with the peak bat activity season in Hampshire. If evidence of bat presence is identified during this period, additional winter surveys may be required to assess the potential presence of hibernating bats.

Further advice regarding bat activity and species of bat to be found in Portsmouth has been provided on the Hampshire Bat Group website.

Typically, the process of conducting a bat survey follows a structured approach that helps inform a bat mitigation strategy:

Preliminary Roost Assessment (PRA): Initially, it is practical to assess whether bats are likely to be roosting in a building or structure. This is a crucial part of understanding how a proposed development might impact local bat populations. The consultant will perform both internal and external inspections of the site, looking for signs of bat activity, such as droppings or visible entry/exit points.

Dusk and Dawn Emergence Surveys: If bat activity is suspected following the preliminary survey, more detailed emergence and re-entry surveys will be necessary. These surveys provide key information about bat behaviour, roost locations, and feeding habits.

• Dusk surveys are conducted at sunset to observe when bats leave their roosts, while dawn surveys occur at sunrise to monitor when they return.
• The use of specialist equipment such as thermal imaging cameras and automated bat detectors helps collect data with minimal disturbance to the bat roosts.

Nocturnal Bat Surveys: Since bats are active during the night and rely on echolocation, nocturnal surveys are carried out to observe their nighttime activities. These surveys allow consultants to track bat movements, feeding areas, and flight paths. Equipment like bat detectors and sometimes radio tracking is used to monitor their behaviour and identify the species present.
