Elevated nitrogen deposition alters soil biogeochemistry and associated ecosystem processes that can lead to plant mortality and decline in stand productivity. Understanding the effects of elevated nitrogen deposition as a result of different land use practices is critical for predictive understanding of ecosystem [...]

Sand dune plants or psammophytes include creepers like beach morning glory (Ipomea pescaprae) and sand spinifex (Spinifex littoreus). These vegetations serve as binding agents to form sand dunes which in turn act as a shelter for some marine animals during the breeding [...]
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 [...]
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 [...]
Deterioration of soil quality with continuous plantation of teak (Tectona grandis)
Wednesday, March 3rd, 2010N.T. Diyalawaththa1, R.M.D. Alawathugoda2 and P.I. Yapa1
A study was carried out at Rathmale teak Plantation, Thalawa to investigate the cause for the poor growth of teak saplings in a selected area. The study hypothesized that the poor growth and development of second rotation teak is a result of poor physical and chemical properties of the [...]

Timber production in high density planting of Hevea brasiliensis
Tuesday, February 2nd, 2010T.U.K. Silva, V.H.L. Rodrigo, 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 of [...]
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, [...]
