Plate 21b: Trees along paths

Tree growing along bigger roads is more complex. Road safety requires
that trees not be grown too close to the road. Ownership issues may
also arise, and the road authorities must be involved in planning and
decision-making.

Areas where the practice is relevant

This practice is relevant in all areas with permanent settlements.

Establishment and spacing
Any propagation method can be used, the choice depending mainly on
species. Initially, spacing can be as dense as 0.5 m, but later the trees
should be thinned to allow them to grow to the desired size.

Management aspects

Management is the same as for trees in fields, but trees along roads
may not always be pruned or pollarded.

Benefits

The benefits are the same as those from trees in fields, and in addition
the trees will reduce dust from roads.

Examples of species

Almost any desired species can do provided that it is well suited to the
ecological conditions of the area. Competitive species can be used in
situations where there are no nearby crops.
