I'd put a "living snow fence" along the north side for a good barrier. This is accomplished by five rows of evergreens and shrubs...Starting on the North or West side (to work against the common winter winds N, NNW, NW, WNW) ususally split as 2 rows of white pine, or a spruce variety, followed by two shrub rows (crabapple, russian olive, or what ever shrub you prefer...please no honeysuckle) and the last row (the southern most) would be another pine or spruce. I've seen it split as 2pine, 1shrub, 1pine, 1shrub (N to S) also.
These rows should be about 8-10 feet a part and planted with 8-10 ft between the pines and 4-6 feet between the shrubs.
I would plant a mixture of grasses over the rest with some "random" pines, cedars, or spruces mixed through out. My grass mix would consist of Big Blue, Canda Wild Rye, and Side Oats Grama.
I would also consider a wildflower mixture as well...AND, I would establish the grasses and wildflowers first, and the living snow fence and intermingled trees second...so it would be at least a two year project.
