With the age.... Depends on: Personality + Farm Terrain/cover/food & deer density..... for example: aggressive and not a lot of great bedding OR the thin timber, wide open/lack of cover - lower deer population..... Big territory- i'd say 500-600 acres, maybe more.
On other extreme, see this every year..... I've got a few pockets that are MAYBE 30-50 acres and the older bucks who end up with dominance almost never leave them. Including rut. Year in, year out, mature bucks fight for the same turf over and over and over & it's only gonna hold so many of em. When that's their home, I got a couple locations with a few different stands I can kill em out of. Go 500 yards further and I'm 99% sure I'll never see em over in XYZ location.
The WORST scenarios I've ever seen, we probably all have.... Summer pics of MATURE BUCKS and come October, they are GONE. Often times, IMO, to go find that core little 30-50 acre pocket they end up dominating. I have seen some bucks on my farm be consistent at "XYZ" spot all summer (food reasons, in bachelor group, get along with other bucks, lots of extra cover like weeds & corn, etc) and come October-ish, boom, they relocate to another area and stay there all season long. Why I wanna have as much thick nasty bedding as possible, seclusion, areas that don't get messed with, thermal cover, nearby food, etc. If bucks get run off or relocate, I personally wanna stay the heck out of the prime areas and make sure they can go there and make it home & feel safe (until it's too late hopefully!
