Used to be, when fur prices were high and predator densities were low, turkeys, quail, and rabbits could prosper in mediocre habitat. Now, the habitat has to be something special. My property is something special. It is managed strictly for wildlife - from butterflies to whitetails - but for turkeys and quail - 350 acres isnt enough when your neighboring landowners arent helping. The only turkeys within miles of my place live on a 1000 acre cattle ranch. There is some hardwood there, but the pastures are fescue and generally grazed to the ground. My land is mature hardwood mixed with open areas of NWSG, acres of year round food plots, mast producing trees, etc - yet the turkeys choose the fescue pasture.
The below podcast with Dr Chamberlain from U of GA is pretty eye opening. When he is discussing survival rates of turkey nests and poults - makes you wonder how there is a turkey left alive with everything eating them.
