In 2013 Worcestershire Bat Group became a member of the iBats programme. This project was supported by a grant from Opal and the Big Lottery.
The survey allows all members to take part in useful research that may otherwise be to strenuous or difficult to activily participate in. The process is simple. A time expansion bat detector is attached to a vehicle and is set to constantly record. In this instance the detecor records for 0.4 seconds, then plays back the recording 10x slower to a recording device and GPS logger. In effect this creates a sample of bat activity in an area.
The recordings and GPS data are then downloaded and the recordings analysed on a computer to identify the bats. These calls are then matched to their geographic location from the GPS data.
To date 13 members of the group have taken part, covering over 1000km and recording over 2262 records which have been submitted to the Worcestershire Biological Reords Center.
The map below shows all the 1km squares (orange) that have produced bat records from this survey up to May 2016. It also shows some proposed routes that need doing. We need to fill in the blanks!
