I dont think it's a refusal to understand in many cases by state biologists... but rather a function of necessity... money Trumps wildlife... even to the state wildlife agencies (NOT just TN or MS). Self preservation of the department is essential. And the vast majority of $$$ is coming in from deer hunting. And jeez, it doesn't take a biologist to mange deer in the south. They do great with no management at this point.
Management of turkeys is like growing orchids (my mom used to grow the most beautiful orchids in a greenhouse we had attached to our house). The first couple years they grow great in any pot... the next few years, they take a lot of work repotting, pruning, etc. Finally after 5 to 10 years they bloom.... and at that point, they will continue to bloom with only water and sunlight... but 5 or 6 years later, they take as much work to maintain as they took at the beginning to get started. We're at that point with turkeys. What worked 5 or 6 years ago to keep them going is not going to work any longer.
