2. Definition
A method of silviculture procedure
worked out in accordance with
accepted set of silvicultural principles
by which crop constituting forests are
tended , harvested and replaced by new
crop of distinct form

14. Coppice Systems
1. Simple coppice system
2. Coppice of two rotations
3. Shelterwood coppice systems
4. Coppice with standards system
5. Coppice with reserves system
6. Coppice selection system
7. Pollard system

16. The Clear- felling
systems
Usually artificial, often by taungya.
Natural regeneration is sometimes
possible from seed from adjoining
areas or from seed already on the
ground or from coppiced advance
growth
Very even-aged
The Clear-Strip System Usually artificial though natural
regeneration is often possible from
adjoining area.
Even-aged
The Alternate-Strip
System
Usually natural on the initially
cleared strips; natural and /or
artificial on the intervening strips
when felled.
Even- aged
Clear Felling Systems
17. The Uniform System Mainly, often largely
assisted by artificial
regeneration
Even-aged as the
regeneration interval is short.
The Group system Mainly natural, though
control of the mixture is
often assisted by sowing
and planting
Uneven when young, but
even-aged later if the
regeneration interval is short,
otherwise somewhat Uneven-
aged.
The Shelterwood-Strip
System
Mainly natural Even-aged as the
regeneration interval is short.
Wagner’s Blender-
saumschlag
Natural Even-aged along the length of
he strip but uneven-aged from
north to south
Shelterwood System
18.
19. The Strip and Group
System
Mainly natural More or less even-aged as
the regeneration interval is
short
Eberhard’s Wedge System Natural Even- aged as the
regeneration interval is
short
The Irregular Shelterwood
System
Natural Uneven-aged as the
regeneration on interval is
long
The Indian Irregular
Shelterwood System
Natural Uneven-aged as the
regeneration interval is
long and immature trees of
the old crop are retained as
part of the future crop
20. The Selection Systems Natural Uneven-aged with all age classes
mixed together on each unit of area
The Group Selection
System
Natural Uneven-aged
Selection Systems
21. Two-storeyed high forest system Partly artificial Two-storeyed
High Forest with Reserves
System
Mainly natural Two-storeyed
Improvement Felling system Natural Uneven-aged
Accessory System
22. The Simple Coppice System Coppice; often assisted by
artificial regeneration strips,
lines, or large rabs.
Even-aged
The Coppice of Two Rotation
Sytem
Coppice Underwood and overwood
even-aged but of different
ages
The Shelterwood Coppice
System
Coppice Even-aged
The Coppince with Standards
Sytesm
Mainly Coppice Underwood even-aged.
Overwood uneven-aged
The Coppice with Reserves
System
Mostly by Coppice Irregular groups of even-aged
coppice with uneven-aged
reserved crop. Considering
the entire crop, unevenaged.
The Coppice Selection
System
Mainly Coppice Uneven-aged
