INDEPENDENT LINES OF EVIDENCE OF A GENETIC RELATIONSHIP BETWEEN ACOUSTIC WAVE VELOCITY AND KRAFT PULP YIELD IN EUCALYPTUS GLOBULUS

  Multiple lines of evidence suggest acoustic wave velocity (AWV) would provide a rapid and efficient method to indirectly select for superior pulp yield in Eucalyptus globulus breeding programs.   Abstract Eucalyptus globulus is one of the

ACOUSTIC EVALUATION OF LOBLOLLY PINE TREE- AND LUMBER-LENGTH LOGS ALLOWS FOR SEGREGATION OF LUMBER MODULUS OF ELASTICITY, NOT FOR MODULUS OF RUPTURE

Loblolly pine (Pinus taeda) logs can be evaluated using acoustic velocity whereby threshold acoustic velocity values can be set to ensure lumber meets specified mechanical property design values for modulus of elasticity   Abstract There is a

Mortality, re-sprouting vigor and physiology of coppice stumps after mechanized cutting

Mechanized cutting may result in higher stump damage levels, especially if cutting is performed with shears. Nevertheless, stumps cut with mechanized technology do not show higher mortality rates than do stumps cut manually with a chainsaw. One-year

Site factors as predictors for Pinus halepensis Mill. productivity in Spanish plantations

This work presents a discriminant model to predict Pinus halepensis forest productivity using parameters related to water availability (Annual Hydric Index, soil porosity and slope) and information about the N immobilization by soil microorganisms (microbial biomass N).

Model performance of tree height-diameter relationships in the central Congo Basin

Tree heights in the central Congo Basin are overestimated using best-available height-diameter models. These errors are propagated into the estimation of aboveground biomass and canopy height, causing significant bias when used for calibration of remote sensing products

Is leaf area of Norway spruce (Picea abies L. Karst.) and European larch (Larix decidua Mill.) affected by mixture proportion and stand density?

Trees with otherwise equal dimensions have different leaf areas if they are located in different stand types. While leaf area of European larch is affected by mixture proportion, leaf area of Norway spruce is affected by stand

Reconstructing forest canopy from the 3D triangulations of airborne laser scanning point data for the visualization and planning of forested landscapes

We present a data-driven technique to visualize forest landscapes and simulate their future development according to alternative management scenarios. Gentle harvesting intensities were preferred for maintaining scenic values in a test of eliciting public’s preferences based on

Disturbance severity and canopy position control the radial growth response of maple trees in forests impacted by emerald ash borer (Agrilus planipennis)

Radial growth of silver and red maples was investigated across three forests in northwest Ohio following the outbreak of the invasive emerald ash borer. The growth response of maples was driven by an advancement in canopy class

Primordium initiation drives tree growth: Opinion paper by Ronald M Lanner

I have become increasingly convinced that this cycle is an entity so well integrated that it seems hardly possible to investigate or survey any of its parts successfully if they are separated from the whole (Sarvas 1974,
