Modeling Loblolly Pine Dominant Height Using Airborne LiDAR
<p>The dominant height of 73 georeferenced field sample plots were modeled from various canopy height metrics derived by means of a small-footprint laser scanning technology, known as light detection and ranging (or just LiDAR), over young and mature forest stands using regression analysis. LiDAR …

Modelling of Biomass Production Potential of Poplar in Short Rotation Plantations on Agricultural Lands of Saxony, Germany
… age and site variables were used to model stand dominant height and in step two the constructed dominant height was involved with stocking density to predict stand oven dried biomass. Depending on data availability the model was parameterized for four different groups of poplar clones: …

Development and testing of climate-sensitive site index models for long rotation Eucalyptus grandis in Limpopo province of South Africa
ENGLISH ABSTRACT: Accurate prediction of height growth and site productivity in Eucalyptus grandis plantations has become increasingly important as the forestry sector faces rising climatic variability and long-term shifts in temperature and rainfall regimes. Although numerous growth and yield …

Modeling General Response to Silvicultural Treatments in Loblolly Pine Stands
Basal area and dominant height growth and survival models incorporating general response to silvicultural treatments for loblolly pine stands were developed using data from various silvicultural experiments across Southern United States. Growth models for treated stands were developed by …

Ecological site quality, site index, and height growth of white spruce stands in the sub-boreal spruce zone of British Columbia
… and white spruce [Picea glauca (Moench) Voss] height growth, vegetation, soil, foliar nutrient, and stem analysis data were obtained from 102 white spruce-dominated stands across a wide range of sites throughout the Sub-Boreal Spruce (SBS) biogeoclimatic zone of central British Columbia. The …

Nocturnal Habitat Selection During Spring Migration by American Woodcock (Scolopax minor) in Central Kentucky
… shrub/sapling/vine, and litter), litter depth, dominant plant height, dominant plant species, distance to escape cover, and percent vertical cover. There was no significant difference (P > 0.05) between sexes or age classes for any of the habitat variables assessed. Logistic regression analysis …

Efficient Sampling Methods for Forest Inventories and Growth Projections
… plot- and stand-level aggregations, subsampling height for volume estimation, and updating stand projections using periodic inventories. A series of simulated loblolly pine plantations with varying degrees of spatial heterogeneity were generated at different stages in stand development. Repeated …

Modelización de la producción de biomasa de Eucalyptus nitens (Deane & Maiden) Maiden en corta rotación para cultivo energético
… por dos funciones de transición (altura dominante y área basimétrica) que proporcionó un alto grado de precisión. Las curvas de crecimiento obtenidas para el índice de sitio fueron 5, 8, 11 y 14 m para una edad de referencia de 4 años. El incremento medio anual de biomasa aérea varió …
