I agree. What you are descibing just wouldn't work as well as you may hope on the size of area you have. I think you need to do one of the other, either plant a stand of pines or an orchard, but not both. The pines will take a little while to get big enough to be beneficial and if you were to plant whites, the deer tend to browse them hard, which will slow growth even more. However, once established they provide great thermal cover for winter. That small of an area would probably be better planted with a mix of apple, pear, persimmon, ect. Just remember apples and pears can need more than one variety (macintosh, granny smith, golden and red delicious, ect.) to pollinate each other, or find self pollinating varieties. Ask your local garden center or co-op which species work best together in your area.
