There are no usable websites that I can find that might help me find that info. I'd like the answer directly or have a web link to it at least.
Some direct threats to black racers and wild snakes in general are humans , cats, hogs, both domestic ones housed outdoors and wild/feral hogs, King snakes, hawks and other birds of prey and getting ran over when they try to cross a road or use it as a basking surface.
Another threat would be loss of habitat as land is developed for neighborhoods and other human use.
I'm going to go with the ignorance idiots that kill them constantly.
