Læhegn

Læhegn is a Danish term that translates to "shelterbelt" or "windbreak" in English. It refers to a row of trees or shrubs planted to protect an area from wind. These plantings are strategically placed in agricultural landscapes, along coastlines, or around buildings to mitigate the damaging effects of strong winds.

The primary purpose of a læhegn is to reduce wind speed. By slowing down the wind, læhegn help prevent soil erosion, protect crops from physical damage, and reduce moisture loss from plants and soil. In coastal areas, they can act as a buffer against salt spray. Around homes and farm buildings, they can provide insulation, reducing heating costs in winter and offering shade in summer.

The composition of a læhegn can vary depending on the desired function and local environmental conditions. Common species include coniferous trees like spruce and pine, which offer dense year-round protection, and deciduous trees and shrubs like ash, willow, and hawthorn, which provide a mix of wind reduction and habitat for wildlife. The density and height of the læhegn are important factors in its effectiveness.

Læhegn are an established practice in many countries, particularly in Northern Europe, where windy conditions are common. They contribute to sustainable land management by enhancing biodiversity, improving soil health, and providing economic benefits through crop protection and resource conservation. Their maintenance typically involves pruning to maintain density and shape, and occasional replanting to ensure the shelterbelt remains effective over time.
