Around here, white pine will grow pretty fast and make an effective wind, noise, and vision block in a short time. What to use depends on your soil, climate, and intent. I'm going to guess that you are close to Yellow Pine habitat. That stuff makes nice, tough barn wood, but I don't know about how fast it grows.
Do you have a county Soil Conservation Service? Around here, they sell packages of trees in the spring for a good price. They're small, but you can get some nice stock for a good price and it grows pretty quickly.
For deciduous trees, there are numerous hybrid poplars that grow very quickly, often more than a foot per year. You could mix these in among two rows of pines and have a good living fence in a relatively short time.
Another option, depending on what you want to accomplish, is to plant something more along the lines of a large shrub (NOT mulitflora rose!) which will make a good vision/noise/wind fence faster than most trees, but won't get as tall, topping out around 15 feet for the big ones. Autumn Olive and Russian Olive also make good habitat for small wildlife. Again, check with your local farm service agencies to see what will work best in your area. Things that work well in some places quickly become pests in others.
I have about 300 ft of road frontage that I want to visually separate from our pasture area. I'm looking for advice on quick growing trees to provide that type on coverage as quickly as possible. Any suggestions? Thanks
