NBMP Survey

The objective of this tutorial is to teach you how to take part in the NBMP Field Survey. You don’t need to be a bat expert to help us to monitor bats, but you do need some training and experience in using a bat detector to take part in this particular survey.

The Northern Ireland Field Survey aims to collect data on three bat species simultaneously from a single 1km square. The species are:

• Leisler's bat (Nyctalus leisleri)
• Common (45) pipistrelle (Pipistrellus pipistrellus)
• Soprano (55) pipistrelle (Pipistrellus pygmaeus)

This survey is carried out with the aid of a heterodyne or tuneable bat detector to enable you to hear the sounds that these bats make.

Once you have completed this tutorial you should feel more confident to take part in this survey. If you do need any further help or advice please contact the NBMP team at the BCT.
