Plantation Silviculture

Plantation Silviculture

Silviculture is the practice of controlling the establishment, growth, composition, health, and quality of forests to meet diverse needs and values. The practices include spacing, weeding, pruning and thinning.

Plantation Silviculture aims to develop silvicultural techniques which help deliver sustainable   plantation forest management based on a scientific understanding of how forests function.  Research is founded upon ecological and physiological understanding of tree growth and development over time. Therefore the activities involve all stages of tree and forest development and the impact of different strategies upon the outputs from forests.

Research provides information to support the development of national forestry policy and  advice to forest sector, forest nurseries, tree seed producers, other research  establishments, the academia such as  universities and other tertiary institutions.
