Screening tree which complements native trees?
I'm not sure if this is the appropriate forum, but here goes....
In short, I am wondering what sort of trees I might buy which would provide good year-round screening, but not look out of place in front of a backdrop of native New England woodland.
I live in a fairly heavily-wooded area of NH. Without going into too much detail, my house is set back from the road a bit, in a clearing, but surrounded by native trees - many American Beech, some oak, some ash, not many maples, some hemlock, some white pines. The dominant tree in my area of concern is the beech.
Despite my neighbor and I having over 18 acres between us, our houses are perhaps 200 feet apart, if that. We have quite a bit of privacy when the leaves are on the trees, but after some recent storms which have thinned the wooded barrier, and some vegetation removal by the neighbor, we no longer have much privacy after the leaves fall. We're not interested in building a fence - the survey and installation would be very expensive, given the size of the property, and hilly/rocky topography.
We would like to plant some screen trees further onto our property - on the clear side of the wooded area. Picture a backdrop of mainly beech, and some new evergreen trees planted in strategic spots close to the beech, to "fill in" areas where our neighbor can see clear through to our house. What would look normal and is easily available? (We did transplant a relatively large native hemlock ourselves, with great and comical effort, but great success, but right now we're looking at trees available from most nurseries.) Arbor Vitae, maybe? We want it to look relatively natural, not like a "landscaped" tree.
