The way I figure it...
Easterns are now worth around $400-500 per bird; Merriams are $500; Rios are $750, and Osceolas broke $1000 per bird a few years ago. Thats what outfitters will pay landowners to bring folks on their properties to shoot a turkey. So thats what the birds are 'worth' on the open market. Then figure those numbers on how many birds you, your kids, and other lease holders actually expect to kill that season. Multiply number of birds by subspecies killed, then total number of acres and that's what the property is 'worth'. Add or subtract fudge factors such as remoteness, limited tags in that state/ unit, experience of the property itself, etc and you come up with a value. There is significant 'value' as well in hunting a property that you hear birds and at least have a chance of killing one.... esp compared to hunting a property that has zero birds on it or around it that day with zero chance for a kill. You are still turkey 'hunting' on either property, but the experience just isn't the same turkey hunting where there are no turkeys. Sort of like speckled trout fishing in a freshwater swimming pool.
At least thats the way I look at it.
