Silviculture Basics

Clear felling involves clear-felling the total area of the mature crop assigned to the system annually in one operation.

In the Shelterwood system, mature trees within a forest stand are not all harvested at the same time; instead, they are removed in a series of cuts over a period to encourage tree reproduction and result in an even-aged stand structure.

Seed trees in the Clear Felling system serve as a source of seeds for natural regeneration after the clear-felling operation.

In the Coppice system, all stems are cut at the same time, while in the Shelterwood Coppice system, trees are cut in multiple entries over time to maintain shade and shelter for regeneration.

Clear Felling can make the land more vulnerable to erosion, reduce genetic diversity, and pose challenges for regeneration in hot exposed areas.

The Two Rotation Coppice system involves two cycles of cutting and regeneration before the next rotation, while the Standard Coppice system has a single cutting cycle per rotation.

The art of cultivating forest stands by applying scientific knowledge to control their establishment, growth, quality, and health.

To make forests useful to mankind on a sustainable basis.

It refers to the optimal rotation age required to derive maximum value from a stand of timber.

The economically optimum rotation age is determined by calculating the maximum net present value (NPV) where NPV = Present Value of Revenue (PVR) - Present Value of Cost (PVC).

Revenue is calculated as Volume X Price, while Cost includes the cost of harvesting and handling.

Determining the optimal rotation age helps in balancing economic benefits with ecological sustainability.

It depends on whether the species is a strong light demander or a shade lover, the frequency of flowering, the germination percentage, and the vigor of coppicing.

It is important for slopes liable to erosion and river catchments to ensure sustainable forest growth and health.

It is crucial for areas prone to storms, heavy winds, snow damages, frost, drought, or pest damages to protect the forest ecosystem.

Management objectives like charcoal production, small timber production, large size quality timber production, or even pole production guide the selection of the silvicultural system.

Economic considerations such as low operational cost, low investment, and early return on capital invested impact the feasibility and sustainability of forest management practices.
