Ecobat provides tools for the standardised, rigorous interpretation of bat activity data

Please note, we are currently in the process of updating Ecobat so you may notice the upload and analysis of data has changed. Guidance documents will be available soon! Thanks for your patience.

Thank you to everyone who joined our webinar on 11th April, we hope you found it useful. If you missed it, you can watch it here. If you have any further questions, please contact or join our new Google forum and post your question there:!forum/ecobat-chat 

** Ecobat currently does not take into account species' absences, ie. nights when a species was not recorded. We are updating this now and hope to have this included for the within-night analyses by Easter weekend **

How Ecobat can help:

1. Quantify bat activity relative to local and national datasets - to help identify sites at risk from development

2. Assess nightly variability in bat activity - to help identify sites with roosts nearby

3. Produce easy-to-use, report-ready summaries - to make your life easier
