What Happens to Your Data?
Once all data are collected for the year they are analysed by our statistician using a variety of techniques to identify bat population trends. Studies are also made to identify any possible areas of bias.
All of the results along with details about statistical models used, Power Analysis and the way in which trends are calculated can be found in our NBMP page on the website. You can view maps of species and surveys or download one of our reports for more detailed information.
Feedback on individual site data is provided to all surveyors who sign up to survey a square that has been done before. You can also sign up to receive the bat e-bulletin for more general information.
Any local bat groups that request data for their county will be provided with summary data for the area – the species counts and general location – to help with local conservation. Your contact details will not be passed onto bat groups or any other organisation.
Data from the Waterway Survey are made available on the National Biodiveristy Network Gateway.
We highly recommend that you do get in touch with your local bat or mammal group; they may be able to help you with your survey. More information about your local group can be obtained by going to the Local Bat Groups section on the BCT website.
Any other requests for data are dealt with on a case by case basis but your contact details will always remain confidential.
