Detectors to monitor bat populations Bats play a vital part in our ecosystem and we’re incredibly lucky to have several species on our farms. Monitoring their numbers and wellbeing tells us a lot about the general health of the environment. With your help, we will buy 15 bat detectors to use on evening bat walks, giving both our monitoring team and farm visitors the chance to learn more about them.
