windbreak (redirected from shelterbelt)

windbreak

a physical obstruction to the passage of the wind, usually in the form of a line or copse of tall bushes or low trees or a porous fence. Of very great importance in temperate climates and periods of cold, wet, windy weather. Neonatal lamb mortality, off-shears hypothermia of sheep and hypomagnesemia and lactation tetany are some of the risk diseases in these circumstances.

During sheep weather alerts it may be necessary to improvise shelter. Some methods are: rows of bales of hay, mowing swathes of tall vegetation in a cereal crop or overgrown pasture being kept for hay. The sheep lie down in the alleys and keep out of the wind.
