Leaf area index (LAI) is an important parameter in plant ecophysiology; it can be used to quantify foliage directly and as a measure of the photosynthetic active area and, thus, the area subject to transpiration in vegetation. The aim of this paper w

Background Among the most important aspects of risk and hazard studies relating to forest ecosystems are maximum forest density and density-dependent tree survival. Methods Long-term observations about the maximum density of unthinned Pinus patu

Background: Estimating forest productivity is critical for effective management and site assessment. The dominant height is used to calculate the Site Index (SI), which is commonly used to assess forest productivity. In this study, an algebraic diffe

Because of the high cost of maintaining a series of unthinned, densely stocked stands over long periods of time, suitable data about potential forest density and tree survival for different planting espacements are difficult to find. Direct assessmen

This study presents an application of a stand table projection method for varying stand densities of Eucalyptus grandis in South Africa. The projections of diameter at breast height (dbh) class frequencies are compatible with future values of basal a

Production of Pinus radiata was greatly increased on poorly drained soils by planting trees on elevated planting beds or mounds and an application of phosphogypsum (PG). At 8.5 years of age, timber yields were improved five times by bedding alone or

Prior research in 2005 and 2008 estimated planted forest investment returns for a set of countries and included some natural forest species in a few countries. This research has extended those analyses to a larger set of countries and focused on plan
