Monday, February 1st, 2010W.A.S. Lakmali and S.M.C.U.P. Subasinghe
Mahogany is one of the renowned timber species for its beautifully grained, hard and red-brown wood. It is an introduced timber species, dominated in Sri Lankan forest plantations with fast growth rates and higher timber value. Mahogany plantations are widely established in the intermediate zone and low country wet zone in [...]
Investigation into the optimal fertilizer regime of Swietenia macrophylla (Mahogany)
Monday, February 1st, 2010S. Jayasinghe and D.M.S.H.K. Ranasinghe
With the increase of the population in Sri Lanka, and increase of the demand for timber, the requirement to produce wood in country in large scale as intensively managed plantations has become very important and urgent. As forest tree planting has to compete with agriculture for land, the land relegated [...]
Estimation of carbon stock in Kandyan Homegardens located in Kandy and Matale
Monday, February 1st, 2010W.A.S.S. Dissanayake1, D.M.S.H.K. Ranasinghe1, S. Wahala2
Increasing levels of atmospheric greenhouse gases due to fossil fuel use, deforestation and other anthropogenic sources have changed the global climate. Global warming is the most widespread problem of the new millennium. Carbon dioxide (CO2) is the most important greenhouse gas released as a result of human activities. Stabilization of [...]
An Assessment of Groundwater Quality in the Land Area around the University of Sri Jayewardenepura
Thursday, January 21st, 2010B. Dorakumbura, W.D.W Jayathilake
The groundwater quality in the land area around the premises of University of Sri Jayewardenepura which belongs to Boralesgamuwa, Gangodawilla and, Nawinna in Colombo district was investigated. The land area was divided in to 4 clusters depending on the population and water samples from 96 randomly selected domestic wells were obtained during [...]
Aboveground tree carbon stocks of Lowland evergreen mixed vegetation at Gannoruwa
Thursday, January 21st, 2010P.S. Pathinayake, M.D.P. Kumarathunga, S.P. Nissanka
Conservation of global forests is being considered as one of the sustainable ways of mitigating global warming, because forests are widely perceived to act as major sinks for atmospheric carbon. Estimation of carbon stocks of tropical forests are important for management, planning and for REDD initiatives.Therefore, this study was initiated [...]
Deterioration of soil quality with continuous plantation of teak (Tectona grandis)
Thursday, January 21st, 2010N.T. Diyalawaththa, R.M.D. Alawathugoda and P.I. Yapa
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 [...]
Biomass estimation in some dry zone forests in Sri Lanka from Forest Inventory Data
Wednesday, January 20th, 2010M.D.P. Kumarathunge and M.C.M. IqbalPlant Biology, Institute of Fundamental Studies, Hantana Road, Kandy, Sri LankaTropical 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 carbon sequestration on the global carbon balance. Long term monitoring plots [...]
Evaluation of Social Forestry Component of the Sri Lanka Australia Natural Resource Management Project
Tuesday, July 21st, 2009This reports the evaluation of the social forestry component of the Sri Lanka Australia Natural Resource Management Project (SLANRMP) in the Kurunegala District. The main objective of this component was to contribute to poverty reduction through improved natural resource management in the dry and intermediate zone of Sri Lanka through community participation.
The study focused on [...]
Evaluation of the effectiveness of the social forestry component of the Forest Resources Management Project (FRMP) in Kurunegala District
Tuesday, July 21st, 2009The paper reports findings of an evaluation of the social forestry component of the Forest Resources Management Project of the Ministry of Environment commenced in 2002 with the overall objective of improving forest management for environmental protection and sustainable utilization of wood.
Three Forest Ranges in Kurunegala District were selected for the study ie Mahawa, Malsiripura [...]
An empirical model for predicting dbh growth with age for Eucalyptus grandis
Tuesday, July 21st, 2009Eucalyptus grandis Hill ex Maiden (rose gum) is commonly grown as even-aged monocultures in colder climates in the hilly region of Sri Lanka. Trees harvested from those plantations are used for sawn timber, railway sleepers and fuel. In order to manage those plantations, estimation of diameter growth is essential with age and therefore that was [...]
