Working with Phil Rosen, Kevin Bonine, Julia Fonseca, and Brian Powell, I have in my free time developed a cool site for citizen herpetologists. It enables citizen scientists to contribute observational data on herps of southern Arizona. In the next few months, we hope to add iPhone and Android applications to it, and to make many improvements to the site. We also want to expand its scope both geographically and taxonomically.
Check it out – HerpCount.org.
We have even gotten some press on it already, for example, here: article on HerpCount.
