Mountainous or hilly areas, or land with thin or rocky soils,
In theory perhaps in practice it does not work. You either reduce numbers in winter(traditionally by salting down the meat) or by supplementary feeding. (Where do you think that comes from?)or you have a much lower headcount for a given area.
To make the idea even remotely feasible you have to deal with the massive overpopulation problem.
The problem no one wants to articulate, much less deal with.
