Data Submission

New in 2020! We encourage you to use our new online form to submit your Big Night counts, as it makes data management much easier on our end. However, if the form isn’t working for you or if you’ve discovered a new crossing and need to convey more detailed location information than the form allows, you can send your data directly to Brett Amy Thelen via email. Photos are best sent as email attachments (see link below) or via links to photo sharing sites (Google, Flickr, Dropbox, etc.)


Site Coordinator Materials

Site Coordinators are the go-to people at our well-established crossings on Big Nights. They manage field gear, hand out data forms, answer questions, and make sure amphibian counts get back to us at the end of each night. In addition to the volunteer materials listed above, the following files might be useful for Site Coordinators, both present and prospective.
