This page is here to bring together an easy, organized, one-stop shop for information on Indiana natural history. It's very much a work in progress, and probably always will be. You'll notice that it's not strictly limited to Indiana organizations or sites. I've also included relevant national institutions or those in neighboring states, since Indiana isn't a geological island. If you have a suggestion, let me know!
