Other surveys

If you have good bat detector skills then we need your help with our bat detector surveys. The simpler of the two is the Waterway Survey which just requires you to count Daubenton's bats as they skim over the surface of the water. The Field Survey is for more experienced surveyors who are able to identify noctule, serotine, common pipistrelle and soprano pipistrelle in the field. If you have access to a frequency division detector (such as the Duet) and a digital recording device, you can take part in the Woodland Survey which focuses on the rare barbastelle. If you are interested in improving your skills we run bat detector workshops, so that volunteers can take part in our field surveys. Or if you know of any summer maternity roosts in your area then you could take part in the Colony Counts. Our simplest survey is the Sunset/Sunrise Survey which is aimed at people with no previous surveying experience.
