Well, just for kicks and giggles, Bull, you said, "...private land..." Did you mean private woodlands? Or, just all non-government owned land? If you want to get into the weeds, and look at private woodland, there's all kinds of classifications depending on who's doing the classifying.
In one of the counties in Virginia where I hunt, a rural county, there are 16,266 parcels (for tax purposes). Something just short of half (45%) are a quarter acre or less.And 75% are less than 5 acres. The percent of parcels in the 5 acres to 75 acre range is around 21%.
At the "big" end there are 326 between 100 and 250 acres; 63 between 250 and 500 acres; 20 between 500 and 1,000 acres. And 3 parcels over 1,000 acres.
Here's the kicker, while the number of parcels over 100 acres is is about 2.5%, the acreage is about half of what's in the county. Put another way, in round, round numbers, there are over 16-thousand land owners, but 50% of the acreage is owned by 412 individuals / entities.
Meaningless I know, but interesting for the numbers nerds like me.
