I did bing it to see what was out there, but thought this turtle wouldn't fall under the category. You are the expert. So, here is what I found. I guess luvcats could call to see what's up or if there are other options.
Hi and thank you for the link. I called Battle Creek and they can't take him. He is an introduced species and grows more quickly than our native species, eats their food, etc. I called Mid-Atlantic Turtle and Terrapin and they said the same thing about him being non-native species. They have already taken in way over their limit of rescues and can't take him. The problem with putting him back in a small pond is that he will have a detrimental impact on the native turtles trying to survive there.
Another source told me of an area that has a lot less traffic and that is where I'll take him this morning.
Thanks again for helping.
