Eric,
Agreed on the point that Norway Spruce is not a native species...I was kinda surprised that both of the govt pros recommended it for my application. The state bio felt that it would be a good tree as it would be shade tolerant...? I do know that they grow pretty quickly; I planted about 50 of em at my principal residence 9 years ago and they are really "takin' off". Whatever choice occurs, tho, it has to be a quick grower, particularly in the 1/4 ac. area where I am going to mix it in with the existing/thinned out hardwoods. In this area, it's primary purpose is to create a visual screen to separate a neighboring property.
