The importance of trees to land management cannot be overstated. Often in the past they have been seen as competing for valuable land space and felled indiscriminately. Over clearing of trees can lead to salinity problems and numerous forms of erosion and land slips. As we have become more familiar with their vital role in ecological processes, retention and selective planting of trees has been widely acknowledged, in improving farm viability and ultimately production. This course develops an understanding of environmental systems and the rehabilitation of degraded landscapes. You learn about seed collection, storage and germination, propagation, plant selection, establishment techniques, controlling pest and disease after planting.
