Document Summary
The theory and practice of controlling the establishment, composition, growth and quality of forest stands. Basic silviculture means planning and seeing; intensive silviculture includes site rehabilitation, spacing and fertilization (natural resources. Usually only one or two species are planed (monoculture) to be grown and cut again in short cycles of 60-120 year. The falldown effect is the reduction in volume and quality of trees caused by the shift from exploiting old growth forests to producing managed forest less time for the trees to build bio-mass (not old growth forests) 42 left is the older tree and the right is the younger. Culmination age = the point to which trees are grown where the average tmber is greatest; trees are considered mature". Economic maturity = the youngest age at which trees can be cut and sold for a profit. Ecological maturity = the age at which wood has developed its maximum fibre length.
