I have used white pines here in Vermont for breaks/screens. They are hearty in drought conditions because they have a long center tap root. They are also fast growing and cheap to purchase.

Honestly 20 ac isn’t a lot (no disrespect intended) so you will need to be smart about how to enter and leave stands without spooking deer. Find your stand locations, then build your plots around those locations. I would put in as many small .25-.50 ac plots as I can. Don’t plant the entire open area as plot, leave a buffer around the edges and let it grow tall with natural vegetation. Deer love the transition and will often bed right there because they feel safe. I use clover/chicory and brassica/turnip/radish as my main plots.

Best of Luck!
