1. Silvicultural systems

2. What is a Silvicultural system?
A silvicultural system is the process of tending, harvesting and regenerating a forest.
Different objectives in forest management (e.g. conservation in an ancient semi-natural woodland vs. production of timber from a conifer plantation) are likely to lead to the adoption of different silvicultural systems.

4. SYSTEMS Generally divide into 2 main groups HIGH FOREST SYSTEMS
COPPPICE SYSTEMS

5. There are many different types of silvicultural systems
CLASSIFYING SYSTEMS
There are many different types of silvicultural systems
A broad classification can be made based on the pattern of regeneration and how the tree canopy is removed.
Forestry Commission.

6. Generally forests managed using clear felling and shelterwood systems tend to be even- aged (only possess one or two canopy strata) and those managed using selection systems are uneven-aged (have three or more canopy strata).

7. Silvicultural systems
Clearfelling
Complete removal of trees and artificial regeneration.
Uniform shelterwood system
Uniform opening of the canopy for regeneration purposes
Strip shelterwood
Opening up of crop in narrow coupes
Opening up of groups of advance regeneration – comparitively short regen period
‘Rolling system’

8. COPPICE SYSTEMS
Coppice
Coppice with standards

11. HIGH FOREST SYSTEMS
CLEAR CUT SYSTEMS - old crop felled in single felling Usually artificial regeneration
Crop felled in 2 or more regeneration fellings
SHELTERWOOD SYSTEMS
SELECTION SYSTEMS
