Mike, map out those oaks at the back of the property before you make any decisions on removal, a map of tree location and the sun travel in both summer and winter can give you lots of insight as to just how many really need to go.
It is a travesty to take out shade and then find out you could have used some of it for things like Blueberry or serviceberry bushes which do like some afternoon shadiness.
We were going to remove a few more than we ended up taking out in the hog paddocks, turned out they used those trees for shade in the hottest part of the day, which necessitated their staying.
We have about 10 acres of north facing slope that is currently au-natural with white oaks and hickory trees. I know I have to thin the forest but I am still mapping all the trees on a sun travel chart.
Then I will be able to decide where and which trees
should become
firewood and lumber. I also have a fair stand of sacred cedars which will have to be thinned so the ones left can flourish and grow in their natural shape.
The removals will become
fence posts, gates and lumber for the wife's cedar closet.
I try to follow earth mother's intentions in all ways and only take out what absolutely has to go. Even dead wood stands until it either becomes a real danger or I need the fire wood.
Our orchard did require removal of some "baby" hickories and oaks but mostly those fruit trees are where there was a stand of Sumac and blackberries. We have a second area, on our south facing slope, which we plan to use for more orchard, it will be interspersed with the vineyard.
