A wind barrier of living trees and/or shrubs maintained to protect farm fields or homesteads.
hedge or fence of trees designed to lessen the force of the wind and reduce erosion
a row (or rows) of trees planted across the prevailing wind direction to slow or deflect the wind
one or a few rows of trees or shrubs planted to reduce effects of soil erosion by wind; designed to deposit snow evenly across cropland
An extended windbreak of living trees and shrubs established and maintained for the protection of farmlands over an area larger than a single farm.
A plant barrier of trees, shrubs, or other approved perennial vegetation designed to reduce wind erosion. Also called a windbreak.
A belt of trees and/or shrubs maintained for the purpose of shelter and wind, sun, snow-drift, etc. Syn. Protective-belt.( BCFT). Shelterbelts are generally more extensive than windbreaks covering areas larger than a single farm ( USDA) and sometimes whole regions on a planned pattern. Cf. Windbreak: Snowbreak.
a natural or artificial forest maintained for protection against wind or snow
A barrier of trees or shrubs planted to provide protection from the weather.
A belt of trees and/or shrubs arranged as a protection against strong winds; a type of windbreak. The trees may be specially planted or left standing when the original forest is cut. A shelterbelt decreases the force of the wind near the ground, both upwind for a distance of up to six times the height of the barrier, and downwind for a distance of fifteen to twenty times the height. These ratios are roughly constant, irrespective of the height of the belt. The lowest wind speed is found downwind at a distance of three or four times the height of the belt. If the trees are too dense, the air beyond this quiet zone is often turbulent, with downdrafts that may flatten crops. The best form is a moderately dense belt of mixed conifers and deciduous trees, five to ten yards wide, containing at least three rows of trees at right angles to the prevailing winds. A system of shelterbelts to give protection to crops over a large area should be planted at intervals of about twenty-five times their expected height.
