Conant says about eastern hognose "Sandy areas are a favorite habitat" In regards to southern hognose "Habitats include sandy woods..."

Tenant, in Field Guide to Snakes of Florida says "Eastern hognoses live in a variety of sandy-substrate habitats...."

Reichling, in Reptiles and Amphibians of the Southern Pine Woods says "the Eastern Hognose Snake is one of numerous species that finds suitable habitat in the pine woods by virtue of its sandy, friable substrate."

I do not think it is even up for debate that hognose are strongly associated with sandy soils, whatever the species of hognose.
