These two activities may be required individually or together. With the
exception of arid areas, these are Regular activities, involving control of
grass, weeds, bush and trees where these are not controlled by animal
grazing. They may be required to be carried out at least once a year after
the rainy season, or more often where the climate causes vegetation to grow
rapidly.
•¡
Grass Cutting
Grass and weeds should be cut at least once a year after vegetation
reaches full growth or according to local experience. The vegetation
should be trimmed by hand. Sickles, scythes, slashers, bushknives, or
similar handtools will be required.
•¡
Bush control & Trees
Any bushes on the road shoulders or drains should be cut down.
Dead or leaning trees within the right-of-way which may fall on the
roadway or block the drainage system, or block sight lines should
be removed. The felling of trees, or the removal of large branches at
heights of more than 2 metres above ground level can be hazardous.
This work should only be carried out under expert supervision or by
experienced workers. Trees should be felled using one- or two-man
saws or axes. Ladders should be used for climbing trees, and ropes
should be used to restrain trees and control felling. Traffic should be
halted when the tree is finally toppled. All debris should be removed
and disposed of safely.
