The Tree and Shrub Sale offers great stock if you are planning a windbreak or privacy row. Start with at least 3-4 rows. The Norway Spruce is excellent and is a fast growing (2-3’ per year) it can grow up to 5 ft a year in a good weather year, another conifer for the tall row is Douglas Fir. For the medium row, Eastern White Pine or White Spruce, for low row, a mixture of shrubs like Lilac or Hazelnut.
Tree and shrub windbreaks are valuable conservation tools with many functions:
Reduced soil erosion — Windbreaks prevent wind erosion for 10 to 20 times their height downwind. They also filter wind-blown soil particles from the air.Energy conservation — Windbreaks can reduce winter heating costs 20 to 40% by reducing cold air infiltration into buildings. In summer water evaporation from leaves directly cools the air. Windbreaks can be designed to provide energy savings for a small residential lot, a farmstead, or an entire housing development.Wildlife habitat — In open areas where windbreaks are needed for wind reduction, they may also provide the only woody cover and food necessary for some wildlife species.Beauty — Trees provide visual screening and permanence in the landscape that other types of plants can not.Crop protection — Windbreaks can increase crop yields up to 44%. Wind protection reduces crop water use, increases a plant’s ability to make food, and may increase pollination. Quality of fruit and other high value crops can be increased due to reduced sand and soil abrasion.Snow control — Windbreaks can serve as “living snowfences”, controlling drifts near roads, buildings, or livestock or distributing snow evenly over large areas likecrop fields. Money and energy are saved by reduced need for snow plowing and artificial snow fences.
Livestock protection —Windbreaks can be used as“outdoor barns,” sheltered areas for feeding, calving, and other livestock-related activities.For questions or design ideas, call 315-946-7200 or email drew@waynenyswcd.org
