Biomass and Nutrient Studies of Selected Tree Species of Natural and Plantation Forests: Implications for a Sustainable Management of the Munessa-Shashemene Forest, Ethiopia
Plantation forests with exotic tree species have been introduced to alleviate the problems of deforestation in Ethiopia. In the future, more plantation forests with fast growing species should be grown for coping with the ever-increasing demands for fuelwood and other forest products. However, it …

Hydrological and erosion responses to man-made and natural disturbances : insights from forested catchments in South-central Chile
… conversion of land into highly productive plantation forests. In this dissertation I combine paired catchment experiments, data analysis techniques, and physics-based modelling to investigate: 1) the effect of plantation forests on water resources, 2) the source and sink behavior of timber …

Using microarrays to elucidate the genetic basis of wood density in sitka spruce and poplar
… human population mean that<br/>natural forests are being lost and degraded. A potential solution to this problem is<br/>to improve the productivity of our plantation forests to relieve the pressure on<br/>natural forests in terms of sustainable wood production. This project is the first …

Diameter Estimation of Eucalyptus spp. Plantations in Southern Brazil Using Global Ecosystem Dynamics Investigation Data and Support Vector Regression
Forest plantations make up a large percentage of managed forest land globally. Assessing plantation productivity is vital from both commodity production and carbon management standpoints. Measuring the productivity of these areas is essential given their rapid growth and turnover. Transparent …

The impact of conifer plantation forestry on the ecology of peatland lakes
… of their catchments by exotic conifers. Plantation forestry can potentially lead to the increased input of substances including hydrogen ions (H+), plants nutrients, dissolved organic carbon (DOC), heavy metals and sediment. The aims of this study were to investigate the effect of conifer …

Tree-Level Forest Monitoring with Artificial Intelligence Using Neural Networks and High-Resolution Imagery
… forest, we can use those measurements to inform plantation management on harvest cycles, we can even use tree measurements to predict climate change. However, for these to occur there needs to be routinely measured and updated forest measurements which can be costly and take a long time to …

MODELLING THE GROWTH OF THE LOGGED OVER INLAND PRODUCTION FORESTS OF PENINSULAR MALAYSIA WITH FOREST MANAGEMENT CONSIDERATION
… develop growth models for inland tropical rain forests and (2) to propose changes to the current management systems and cutting regime options. In the Malaysia context inland forests encompass lowland, coastal hill, hill and upper hill forests, 'flic current management systems reviewed are those …

Development of national extent terrain attributes (TANZ), soil water balance surfaces (SWatBal), and environmental surfaces, and their application for spatial modelling of Pinus radiata productivity across New Zealand
… recently foresters have focussed on maintaining plantation management systems that are highly productive, while remaining sustainable. However, the new era of reduced carbon emissions and carbon trading means forestry systems are now viewed as potential sinks for the sequestration of carbon. …

The roles of exotic and native tree species in preventing desertification and enhancing degraded land restoration in the north east of Libya. Reciprocal effects of environmental factors and plantation forestry on each other, assessed by observations on growth and reproductive success of relevant tree species, and environmental factors analysed using multivariate statistics.
… emphasises the current mismanagement of planted forests, particularly with overgrazing contributing to desertification, through preventing tree growth and eliminating most sapling regeneration. This study concludes by making recommendations for more effective choice of tree species to plant, and …

Modeling the effects of forest management on the carbon cycle in a loblolly pine (Pinus taeda) plantation
Forests have the ability to alleviate the impact of global warming through carbon sequestration. Six forest management scenarios for a 27,000 acre study area are modeled to determine the impact of forest management on carbon sequestration. Forest management determines annual harvested volume and …
