Quick facts
Windbreaks are plantings of single or multiple rows of trees or shrubs that are planted for:- Wind protection
- Controlling blowing and drifting snow
- Wildlife habitat
- Energy saving
- Living screens
- Reducing livestock odor
The effectiveness of a windbreak depends on choosing the right trees and shrubs and planting them at the right density and spacing.
Considerations
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 should 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.
Density
How dense the planting and the number of rows depends on the purpose of the windbreak.For protecting crops and soil and distributing snow:
- Plant at 25 to 50 percent density.
- Plant one row deciduous shrubs and two rows deciduous trees and shrubs.
- Plant at 50 to 65 percent 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.
- See Living snow fences for more information on benefits and how to select plants.
- Plant at 65 percent 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.
Plant spacing
Tree and shrub plant spacing affects active growth. Trees planted too close together may be stunted due to crowding, while too far apart from each other may cause gaps that reduce the effectiveness of the windbreak.Recommended windbreak plantings can be found here. Check spacing recommendations for the specific species you want to plant.
Financial assistance
Cost sharing and annual land payments for land planted to trees as windbreaks, wildlife plantings, shelterbelts and living snow fences may be available.The USDA Conservation Reserve Program (CRP) continuous sign-up offers cost-share, annual payments and incentive payments. Contact your county Farm Service Agency (FSA) office for more details.
Local sources of funding include Soil and Water Conservation Districts, watershed and conservation organizations.
Check with area or county Soil and Water Conservation Districts, National Resources Conservation Service, Department of Natural Resources and Extension staff to get a recommended list of plants suitable for your area.
