Hello,
I'm looking for any information, published references, master's thesis etc., or general knowledge, on communal northern black racer dens in sand dune/pine barren habitats and the sites they choose.

Thanks to anyone that can help.

You can reply off list if you want to naturexchange@aol.com

Best,
Kenny
