NatureServe Explorer
You must provide the species name in the search bar. It does a great job of mapping where they can be found.
Fow example, I did a search on my avatar fish, the Mountain Redbelly Dace:
Just enter this species in the search bar: Phoxinus oreas
and it will bring up an abundance of information.
I've noticed that the Virginia mountains seem to be especially blessed with a lot of species diversity.
