I asked Cornel for documents on the importance of their data. The Biologist involved on the rezoning at Cibolo Planning and Zoning had discounted their value. Thanks Chris for the articles EBird publications on importance of Ebird data Here is a list of publications from eBird data that may be useful. http://ebird.org/content/ebird/about/publications/ You could also direct them to the two State of the Birds Reports, which are based on models of eBird data. http://www.stateofthebirds.org/State%20of%20the%20Birds%202011.pdf http://www.stateofthebirds.org/2013%20State%20of%20the%20Birds_low-res.pdf In the meantime, these two papers provide good overviews: Sullivan B.
