Forest Stewardship Council (FSC) is an international non-profit, multi-stakeholder organization established in 1993 to promote responsible management of the worlds forests. FSC offers a comprehensive set of universally applicable requirements for responsible forest management with its 10 Principles and 56 associated Criteria. Achieving FSC can be further divided into standard setting, independent [...]
Comparison of wood quality of even-aged Teak (Tectona grandis L.f.) plantations in three districts of Sri Lanka
Wednesday, March 3rd, 2010D.P. Weerasinghe and H.S. Amarasekara
Teak is listed as a super luxury timber in Sri Lanka and it has a high demand from construction and furniture industries. Teak hardwood is highly durable. It is an exotic species and, almost all teak plantations are located in dry and intermediate zones of the country. There are about 35,000 [...]
Estimation of biomass carbon of Eucalyptus grandis using IRS LISS III Satellite images in up country wet zone of Sri Lanka
Wednesday, March 3rd, 2010A. Gunawardena1, S.P. Nissanka2, N.D.K. Dayawansa3
There are vital needs to collect some necessary data on forest plantations to address the global climate change that includes carbon sink concept in Kyoto protocol. There are very rapid expansions of forest plantation in Asia-Pacific region and Sri Lanka also have a large extent of forest plantations such as [...]
Forest woodland ecosystem: An insight into the addition of litter through teak plantation
Wednesday, March 3rd, 2010A. K. Mani, S. Manivasakan, S. Vijayabaskaran
Teak is an important tree species grown under plantation conditions for timber requirement. Being a deciduous tree, it favours for accelerated nutrient cycling. A field experiment was conducted in an eighteen year old teak plantation at Forest College and Research Institute, Mettupalayam, Tamil Nadu, India to study the litterfall, [...]
Growth, biomass and carbon accumulation among rubber (Hevea brasiliensis), teak (Tectona grandis) and mahogany (Swietenia macrophylla) A case study from 1 to 10 Years of Age Series
Wednesday, March 3rd, 2010N. Appuhamy1, L. Samarappuli2 and S. Karunaratne1
The study was conducted to compare the biomass accumulation and carbon stocks among rubber, teak and mahogany. Above Ground Biomass of each species were calculated using the allometric models. Mean total tree height of rubber, teak and mahogany were ranging from 0.87 m to 20.32 m, 3.41 m to [...]
Timber production in high density planting of Hevea brasiliensis
Wednesday, March 3rd, 2010T.U.K. Silva , V.H.L. Rodrigo1, S.M.C.U.P. Subasinghe
The demand of natural rubber has increased continuously with the increase in population and living standards of the human being. Rubber plantations are also a major resource of timber and fuel wood. In order to meet the continuous increase in demand for latex, timber and fuel wood, the productivity [...]
Biomass estimation in some dry zone forests in Sri Lanka from Forest Inventory Data
Wednesday, March 3rd, 2010M.D.P. Kumarathunge and M.C.M. Iqbal
Tropical forests are a major sink for carbon dioxide produced globally. Estimation of above-groundbiomass of these forests is an essential aspect of studies of carbon stocks and the effects of carbonsequestration on the global carbon balance. Long term monitoring plots across several tropical dryevergreen forests in India, in the recent past, [...]

Establishment of relationships of growth at 7 years old Mahogany trees with selected site factors in low country wet zone, using GIS as a tool
Monday, February 1st, 2010K.R.A.H.A. Randeni and S.M.C.U.P. Subasinghe
Mahogany (Swietenia macrophylla) is an exotic tree, which is heavily adapted to the climatic conditions of wet and intermediate zones of Sri Lanka. Although the state sector manages mahogany with longer rotations, private sector expects to achieve the maximum timber yield within a shorter period. Due to the land scarcity, [...]
