Plate 25: Windbreak design
Management aspects
As with any other newly planted trees, initially a windbreak needs to
be protected against livestock and fire. Careful weeding and
replacement of dead seedlings also need to be carried out. Later the
trees in the windbreak may need pruning or pollarding to maintain a
suitable density and to minimize the shading effects on crops. Dead
trees or trees that have been blown over must be replaced.
Benefits
The environmental benefits, reduced wind and increased retention of
moisture, are the most important ones. On the negative side, some
land is lost for crop production, but the reduction of wind may well
compensate for the loss of land. In addition, the windbreak will
produce wood.
