2328 It is important to note that with manual revegetation, progress is approximately one hectare in about 20 days with a team of 10 people, whereas with hydroseeding the same work can be performed by three operators and revegetation of one hectare can be completed in approximately 3 hours. Another important factor is safety. In the manual method, personnel must apply maximum safety measures, especially on high slopes where the risk of falling is high. With hydroseeding, it is no longer necessary for personnel to climb these slopes. Figure 5. Manual revegetation method Figure 6.
