A Bat Survey is ordinarily triggered when there is to be:
Ordinarily, the form of initial survey required is a 'scoping survey' designed to investigate the presence of bats and / or the potential presence of bats. This is often in association with a survey for nesting birds.
The outcome of the scoping survey dictates the next course of action:
Emergence surveys are intended to prove that the building is or is not a bat roost. If bats are recorded, the survey records the access / exit point used by the bats, the numbers and species present. A decision is then taken on how to proceed. This could mean a Mitigation - Method Statement or a Natural England European Protected species Licence (EPSL). The exact requirements are dealt with on a case by case basis.
Activity surveys are often required where development is to take place in a previous undeveloped area such as agricultural fields or brown field site which has reverted back to a more natural state.
Each site is individually rated as either:
– One Visit Per Season (April – May / June – August / September – October)
Five nights automated recording per Season
– One Visit Per Month (April – October)
Five nights automated recording per month
– Two Visits Per Month (April – October)
Two automated recorders (Ten nights) per month
Survey effort detailed is in accordance with Bat Conservation Trust (BCT) guidelines.
The objective of the survey is to ascertain what if any bat species frequent the area and devise an appropriate mitigation scheme, to ensure that bats using the site are not prevented from doing so in the future.
