If you look a little deeper, you'll find legislation that specifically prohibits the transportation of ILLEGALLY killed wildlife. It's a long and complicated process when it comes to determining if wildlife killed by a native is legal or not and I won't pretend that I am in a position to begin an intelligent discussion on the topic. Let's presume that in your case it legally harvested. In that case, the "transportation" of the wildlife is not likely the issue. Based on your description, it sounds as if you're actively taking part in the harvest, and that's a grey area beyond the scope of most experts, let alone most lay people. I'm afraid that you'll have to keep asking questions up the chain of command in order to get a satisfactory answer.
