But because the black rat snake scientific classification has experienced many changes in the past couple of decades. The species has been transferred using 3 species suggested to a genus.
These snakes have been formerly put in the genus Elaphe, as Elaphe obsoleta, however, phylogenetic studies transferred them into the genus Pantherophis since the bronchial rat snake (Pantherophis obsoletus). Those modifications were dismissed by studies although, in 2008, the Scotophis had been resurrected to the 3 species.
Another species using these modifications were the fundamental rat snake (Pantherophis spiloides) along with also the southern rat snake (Pantherophis alleghaniensis), though the 3 species are morphologically indistinguishable. In Ontario, the rat snake along with also the rat snake interbreed Together with recent research.

Black Rat Snake Conservation
The black rat snake is among the most frequent snake species found in Central and Eastern United States, and it is not listed as rare, endangered or compromised on a national level.
The species has been listed as Least Concern by IUCN due to its broad distribution, some tolerance to habitat alteration and assumed substantial population numbers.
But these non-venomous snakes tend to be victims of roadkill and individual persecution when confused with additional venomous snake species such as copperheads.
They’re listed as special concern species from the state of Michigan because their habitat has been reduced because of land development.
