I have been asking the same questions for a couple years now and have had numerous discussions with Carl and others about this. The only thing I can come up with is that they do not mind if you keep a captive bred individual of one of these species. Of course, you still have to pay the 25 buck fee every year. Here is a response that was forwarded to me from ODNR regarding an out of state individual obtaining a OH black king.
from wildinfo.wildlife@dnr.state.oh.us
"Your message was forwarded to the ODNR Division of Wildlife. You may want to refer to our website and check our herp regulations
(www.dnr.state.oh.us/wildlife), but Eastern black kingsnakes cannot be taken from the wild in Ohio without a permit. As for breeders in Ohio, you may want to check with the Northern Ohio Herpetological Society or Cincinnati Herp Society or Toledo Herp Society. The "gifter/seller" of all native herps must maintain records of who, when, and where any and all animals are distributed. You will have to check your state's regulations about import as well. Hope this is helpful - just let us know if you have other questions. Thanks for asking!"
So they say these animals cannot be taken from the wild, yet they acknowledge that there currently are individuals in OH who are working with OH specimens.
My best advice would be to try emailing the address above and hope you get a response. I would be greatly interested in hearing what they have to say.
