Windbreaks
A windbreak is a tall, dense, continuous wall of vegetation meant to protect structures, roads or any other important areas from strong, driving winds, soil erosion and snow accumulation. A windbreak can also provide wildlife habitat, pleasing aesthetics and help lower energy costs for landowners. Contact our department to learn more! (608) 339-4268 or Email
HOW IT WORKS:
Multiple rows of trees are planted to protect a farmstead, feedlot or open field from wind and snow. Conifer trees or a mix of conifer and deciduous trees can be used, along with one or two rows of shrubs. The established trees and shrubs slow wind on the downwind side of the windbreak for a distance of 10 times the height of the trees. The windbreak reduces wind erosion, controls blowing/drifting snow, conserves energy used for heating and cooling, serves as a sound barrier, and provides wildlife food and cover.

PLANNING:
Plan the windbreak for at least the north and west sides of the areas to be protected, with the rows extending 50 feet beyond the area. However, don't plan too close to buildings, roads or driveways on north and west sides or snow may accumulate in these areas.Â
Avoid planting windbreaks on the south or east sides of roads or driveways; the trees will shade the road and prolong icy conditions.
Consider whether the mature windbreak will cause a vision hazard for drivers.
Keep plantings at least 20 to 30 feet away from phone or utility lines.Â
A mix of conifers, deciduous trees and shrubs provides the best cover for wildlife.
Space trees 10-12 feet apart and shrubs 4-8 feet apart.
FOR PROTECTING CROPS, SOIL AND DISTRIBUTING SNOW:
Plant at 25 to 50% density
Plant one row deciduous shrubs and two rows deciduous trees and shrubs
FOR PROTECTING AGAINST BLOWING AND DRIFTING SNOW:
Plant at 50 to 65% density
Plant twin rows of deciduous shrubs then:
1st row; evergreen trees
2nd row; evergreen trees and deciduous trees
3rd row; a combination of deciduous trees and shrubs
TO REDUCE ENERGY COSTS, LIVESTOCK ODORS AND NOISE, OR PROVIDE WILDLIFE HABITAT:
Plant at 65% or more density
Plant twin rows of evergreen trees then three or more rows in a combination of evergreen trees and deciduous trees and shrubs.
MAINTENANCE:
Control competing vegetation with tillage or herbicides before planting and for the first three years after planting.
Fence out livestock.
Inspect the windbreak regularly to control damage.
Recommended Small Trees
Space 10 to 15 feet in the row and 20 feet between rows.

WHICH TREES/SHRUBS ARE BEST?
Choosing the best trees and shrubs for your situation is extremely important to ensure an effective, long lasting windbreak. Plants need to be winter hardy and show have a good history of being suitable for the site and soils. Select multiple species of trees and shrubs so, if there is a failure in a row, the windbreak is still effective. A mix of deciduous and coniferous plants is best and should be selected based on the purpose of the planting. Use native plants whenever possible.
Recommended Deciduous Trees
Space 12 to 20 feet in the row and 20 feet between rows.

Benefits:
Reduce energy costs and improve comfort - Use less energy for yourself and your utility company. Planting a row of conifer trees on the north and northwest sides of your property creates a wall against cold winter winds - saving your heating costs by up to 30%. Windbreaks around farm dwellings and rural communities improve quality of life for the inhabitants by reducing wind speed along with noise and dust. Established windbreaks increase property values and enhance aesthetic benefits.
Less fossil fuel is consumed by the utility to create the energy, which means less carbon dioxide emissions.
The best protection from wind occurs when the windbreak is no more than the distance of one or two tree heights from the house. The down-wind side of the trees is where the most snow accumulates, so plant your windbreak a one or two tree-height distance from your rooftop and driveway if you can.
Boost crop yield and quality - By microclimate modification, field and orchard windbreaks have been shown to increase the yield of many different crops. Windbreak protection can be especially valuable in orchards and vineyards of high-value horticultural crops. IPM (Integrated Pest Management) By incorporating plants that attract beneficial insects, windbreaks can also serve to increase biological control of crop insect pests.
Add specialty crops - Non-timber products. By using trees & shrubs that produce specialty food or decorative products, e.g. chokecherry or corkscrew willow, windbreaks can provide extra income.
Improve animal survival and weight gain - Tree-sheltered havens, or living barns, within pastures can make the difference between death and survival for livestock subject to harsh weather conditions, e.g. newborn and newly-shorn sheep. Livestock performance, windbreaks around feedlots have been shown to improve the health and weight gain of cattle and sheep in cold climates.
Produce timber from windbreaks - Multi row windbreaks of fast-growing species such as poplar can be sequentially thinned for timber products while maintaining continuity of shelter.
Control wind erosion - Soil and water conservation. Windbreaks are proven effective in reducing wind erosion of light-textured soils. By dispersing snow evenly across fields, windbreaks help make more moisture available for crops.
Manage snow dispersal - Snow control. Properly placed windbreaks prevent snow buildup around buildings and on roadways.
Wildlife habitat - Trees and shrubs provide much-needed food and habitat for game birds and other wildlife.
Carbon credits - It has been estimated that for each acre planted in field windbreaks, over 21 metric tons of carbon dioxide will be stored in the trees by age 20.
