A global map of wood density

Abstract Wood density influences how quickly woody plants grow, how long they live and how much carbon they store, yet its global variation remains poorly mapped. Here we combined 109,626 wood density measurements from 16,829 species with 300,949 vegetation plots to produce a km-scale map of community-weighted wood ...

Wood density within Norway spruce stems

Silva Fennica, 2008
We studied the variation in average wood density of annual rings, earlywood density, and latewood density in addition to ring width and latewood percentage within Norway spruce (Picea abies (L.) Karst.) stems from the pith to the bark, and from the ...

Wood density variations of Norway spruce (Picea abies (L.) Karst.) under contrasting climate conditions in southwestern Germany [PDF]

Annals of Forest Research, 2013
We analyzed inter-annual variations in ring width and maximum wood density of Norway spruce (Picea abies (L.) Karst.) at different altitudes in Baden-Württemberg, southwestern Germany, to determine the climate response of these parameters under ...

Effects of wood density on mechanical properties of mangrove wood from the Amazon coast. [PDF]

PLoS One
Mangrove forests are essential on the Amazon coast, as local communities widely use their wood. However, it is still necessary to understand the mechanical properties of wood typical of mangroves. Our main objective was to understand the influence of density on mechanical properties.

Physical properties of four ring-porous hardwood species: Influence of wood rays on tangential and radial wood shrinkage [PDF]

, 2019
Some relationships between ray proportions, strength and shrinkage properties and basic density in hardwood species were highlighted. A better understanding of their relationships caused by the variation in moisture content in the hygroscopic domain ...

Geographic Variations of the Wood Density and Fiber Dimensions of the Persian Oak Wood [PDF]

Forests, 2020
Persian oak (Quercus brantii Lindl.) is a valuable native species in Iranian forests with very limited availability of data on its wood properties. The objective of the current study was to determine the influence of altitude and slope on physical properties and fiber dimensions of Persian oak wood.

Modelling the variation in wood density of New Zealand-grown Douglas-fir

New Zealand Journal of Forestry Science, 2017
Background Wood density is an important property that affects the performance of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) timber. In order to develop strategies to achieve certain end-product outcomes, forest managers and wood processors ...

Above-ground biomass and productivity in a rain forest of eastern South America [PDF]

, 2008
: The dynamics of tropical forest woody plants was studied at the Nouragues Field Station, central French Guiana. Stem density, basal area, above-ground biomass and above-ground net primary productivity, including the contribution of litterfall, were ...

Systematic Review: Climate and Non-Climate Factors Influencing Wood Density in the Boreal Zone

BioResources, 2023
Wood density is a crucial factor in determining the quality of wood in boreal ecosystems within the Northern Hemisphere. Climate variables play a significant role in shaping wood density, posing challenges for forest managers and stakeholders in the wood
