What a silvicultural system is
• A planned program of silvicultural treatments in a stand to achieve objectives
• It includes harvesting, regeneration and stand tending

What a coppice system is !
A silvicultural systems in which the new
crop originates mainly from stool coppice
The rotation of the coppice is short
Limited to hardwood species
Also called low forest system

Methodology
This term paper was prepared through
literature survey, by reviewing
• internet,
• books and
• publications
Method of Coppicing
• Best season for coppicing: little before the growth starts in spring.
• Large working area: Difficult to fell trees in short period of time, felling is allowed over a period of dormancy, i.e. from November to March but not later from March and before November.
• The stumps ht: usually 5 to 25 cm
• trees cut: on a slight angle to prevent water from pooling in a stump
discussion
Types of coppice systems(On the basis of pattern of felling)
Simple coppice system
•All trees of the coupe are clear felled with no reservation. The crop produced under this system is even aged.
The coppice of two rotation system•Modification of simple coppice system,•At the end of the first rotation, a few selected poles are left scattered singly over the coupe in the second rotation to attain bigger size
discussion....
Types cont...
The shelterwood coppice system
•Modification of simple coppice system for frosty localities by leaving shelter trees
The coppice with standard system•Part of the crop is retained to form an uneven aged overwood. •The standards are generally of some wind firm, valuable species and may be even of species other than the coppice
Discussion....
The coppice with Reserve System
•well grown saplings and poles are retained and the rest is felled
•object are improving the crop, providing protection against frost and erosion, supplying seed, protecting valuable species
Coppice Selection System•felling is carried out on the principles of selection system but regeneration is obtained by coppice
Discussion....Types cont...
Condition for Applicability
Simple coppice system
•where the factors of locality are low
•incapable of producing larger sized timber
•where there may be demand for fuel, poles and small sized timbers only
Coppice with two rotations or coppice with standards
•applied if large sized timber also required
Discussion....
Application in Nepal and their findings
• Research plots on Silvicultural systems were established at Butwal in 1988. It was found simple coppice is potentially the best one to produce fuel and fodder from tropical Sal forest in short rotation
• in Sagarnath and Nepalgunj Forest Development Project appied on Eucalyptus and sisoo plantations
Discussion....
At Tarahara: Two plots of cassia siamea and Eucalyptus camaldulensis on simple coppice system were established in 1990. The result showed both the species are good for fuel and wood production. cassia siamea is rather better than E. camaldulensis
In Gorkha and Dadheldhura, simple coppice was applied in degraded Sal CF during 050s. The coppice gave good result
Discussion....Application .......
• Some best species for coppicing are: shorea robusta, Acacia catechu, Schima walichii, syzigium cumini, litsea monopetala, Dalbergia , Albizia , Eucalyptus , Castanopsis , quercus etc
• Very simple in application, suitable for private or village common lands, Near settlements
• Reproduction is usually cheaper in comparision to seed
• The yield from the first coppice crop is higher than that of the original seedling crop of the same age
• In the earlier stages, coppice growth is more rapid, and the poles produced are straighter and cleaner than in the same species when raised from seed
