Bats are afforded a high level of strict protection under The Conservation (Natural Habitats
etc.) Regulations (Northern Ireland) 1995 as amended. On assessing your application NIEA
consider that there is reasonable likelihood of bats being present on the proposed site. In order
to meet national and international statutory obligations, NIEA has recommended to Planning
Service that appropriate bat surveys should be carried out prior to the consideration of your
planning application. The surveys should be carried out by a professional ecological
consultant with relevant experience and qualifications in bat survey techniques.
Please note that the following specifications are the minimum requirement. The applicant
should be aware that due to the seasonal and highly mobile nature of bats, further survey work
may be required where timing constraints and/or poor weather conditions occur.
- All survey work and survey reports must be carried out according to the *Bat
Conservation Trust ‘Bat Surveys Good Practice Guidelines’ document. We recommend
that the Bat Conservation Trust reporting template is used for all submissions to the
department.
The applicant must ensure that the commissioned bat surveyor(s) has the necessary
experience and qualifications to carry out this work. It is preferable that the surveyor(s)
is a member of the Institute of Ecology and Environmental Management (IEEM).
The date and time of the survey and the qualifications and experience of all surveyors
must be included in the survey report.
There must be at least 2/3 surveys carried out between May and September. Survey
work must be spaced evenly throughout this period.
Number of surveyors and size of survey area must be specified. If the site is large,
more than one surveyor may be required to cover the whole site. Survey methodology
must be dependent on the area of the site and habitat features present, therefore more
than 3 surveys may be required.
The survey report must include a map (A4 size) showing the location/ transect walked
by each surveyor. The location of any other recording equipment must also be
illustrated.
At least one of the survey visits must include a dusk (emergence) and a dawn (re-entry)
survey within one 24 hour period.
The surveyor must ensure that equipment used is sufficient to identify all species of bat
Surveys must be carried out within one year of submission to the department.Northern Ireland Environment Agency (NIEA) 05/01/11
The information should be presented in a written report and must include a large scale
(A4 size) map. The exact location of roosts, roost entrances, advertising posts,
swarming activity foraging and commuting movements must be shown. All evidence of
use by Bats found, for example droppings, must be included.
If necessary, the survey must recommend the most appropriate ways in which the Bats
can be protected from the impacts of development throughout the duration of the
development.
In the event that the planning application goes to appeal or public inquiry, the person(s)
contracted to carry out survey work may be required to appear at, or give evidence to,
the inquiry.
All located roosts should be reported to the Northern Ireland Bat Group*
Please note that a license is required for the following bat survey methods;
Entering a bat roost
Disturbing a bat roost
Catching or handling bats
Use of an endoscope
