2. TPA (Turkey Permit Areas)

3. (1) Assume that the population of the wild turkey in region i is N i and the number of wild turkeys harvested in region i in period j is y ij. (2)p ij is the removal probability of region i in period j, then the probability that an animal is removed during, but not before period j, is equal to Previous Model
