Just watched it I’d love to do something similar to that on my land. Of course my land is mainly pine plantation so adding 10 acres of oaks would be significant. Why did he plant oaks when it looks like that field was surrounded by acres and acres of mature hardwoods. With just 10 acres why not plant fruit trees, or other nuts like chestnuts, or saw tooths, or even berries like muscadines. Still provides similar cover to other trees and gives you a variety from the naturally occurring oaks the field is surrounded by?
