A bat survey was undertaken by Ecology Network in 2015 to determine what species of bats were in Big wood
A bat survey was completed at Bigwood, London from May/June 2015.
The objective of this survey was to establish what species may be present, and potentially provide some information on their distribution.
Bat activity, comprising entirely common and soprano pipistrelles, takes place throughout Big Wood.
The strong presence of soprano pipistrelle social calls (along with emergence times) towards the north of the site, suggests the presence of a roost.
Three Anabat Express automated frequency division detectors were used for the survey. These were deployed on 28/5/15 and set to record during night time only,
