I Have an interesting case study. Large property (not mine) about 30 yrs of me being able to hunt it. Owners do not like deer. 30 year ago the owners had a pickup bed or so of 100-125" deer killed every fall by invited hunters. Years of me discreetly whining about this took it down to about zero bucks killed. Suddenly a family member got "into" deer, put out mineral for about 5-6 years. Deer went nuts over it digging holes 4' deep. Owner lost interest in deer and they went back to being vermin. Mineral dumps stopped.
Little kids grew up and now they are "into deer". But only "huge" deer. I have pounded the lesson home on what happened during the 5-6 years of mineral being made available to the local deer. I have bought mineral for them to put it out for the deer. They simply will not do it. When I am there and have dumped mineral the excavation resumes immediately but I am simply too far away to keep up with replacing the mineral.
Genetics obviously do not change. For 30 years longevity has been good. Although even the best property has neighbours and poachers. The property has good food, and for the purpose of this story it has been consistent. Point being the one variable was 5-6 years of mineral dumps.
3 of the "big five" came from that time window. The other two of the 5 came from before the 30 yr time frame when Ive been there to witness it.
I'm guessing that $500/year would keep mineral on the ground all year. You can literally dump it off the back of the ATV. The laziness of the modern hunter is amazing to me.
Here is the "wall". Of course there have been a number of 150-170's that didn't make the cut to make it onto the wall.
