Bat Survey Kent: Protected Species Surveys

Bat surveys are undertaken for development sites to inform a planning application and determine the presence of bats within a structure or tree. In Kent, development works, from minor home improvements to major development projects, may require licensing to ensure no offences are committed in relation to the bat community

A bat activity survey will detect the presence or likely absence of bats in a particular area,as well as the number of bats that may be present so that plans can be made to proceed with a development. If bats or bat roosts are found to be present on a site, mitigation and compensation measures must be undertaken before any development work can begin that could affect bats negatively and detrimentally. These measures may include the installation of bat boxes etc.

All species of bats in Kent are protected by several statutes, species including the common pipistrelle bat, greater horseshoe bat, Noctule bat and soprano pipistrelle bat. Any works affecting the lives and the breeding of bats, without first gaining a European protected species license, are against the law. For more information on the local species and bat habitats in Kent then the Kent Bat Group (KBG) hosts a significant amount of relevant information.

In Kent and East Sussex, that active season for bats is during the summer months. Therefore, survey work should be carried out during this time of year to determine the presence of potential bat roosts and maternity roosts. If bat activity or potential roost sites are found during a survey in the summer months, a bat hibernation survey may be required during the winter to establish whether the area is also used by hibernating bats.

Types of Bat Survey, Kent

Though there are many types of surveys that can be carried out to assess a number of details, the two most common are as follows:

Preliminary Roost Assessment/Bat Scoping Survey: This is the first step in the bat surveying process which involves an ecologist carrying out a site visit. They will carry out an internal and external inspection of the building looking for evidence of bats, including insect feeding remains and bat droppings.

Nocturnal Bat Survey/Bat Emergence Survey: This involves surveyors using bat detectors to record and analyse bat calls. They will be either dusk emergence surveys (when bats are leaving their roosts to forage) or dawn re-entry surveys (the end of the night out when all the bats return back to their roosts).

How Can Collington Winter Assist?

The team at Collington Winter Environmental are highly skilled ecological consultants and have much experience carrying out licensed bat surveys on a range of development projects.

The Bat Conservation Trust’s (BCT) ‘Bat Surveys for Professional Ecologists Good Practice Guidelines’ provides specialists with the latest up to date guidelines and information regarding the best practices of bat surveys, ensuring we are always operating to the highest standard and to correct legislation.

Our Ecological Director, Olivia Collington, holds a Natural England bat licence and has worked with several protected species over the years, including bats.
