Biodiversity loss is of global concern, and is due in part to deforestation and high consumer demand for wood and wood products. The neotropical tree species Cedrela odorata (“Spanish cedar” or “cedro”) is economically valuable for its wood and faces threats of overexploitation. Due to strong similarities in wood features...
This study was to investigate effects of growth rate
and cambial age on properties of wood from two increasingly
used hardwood species, red alder (Alnus rubra Bong.) and
Oregon white oak (Quercus garryana Dougl.), for better
understanding factors affecting wood quality in hardwoods.
Thirty 7-year-old trees grown at widely varying...
Many people enjoy going to the beach, but few know how the tides work. People who earn their living on the sea have a special need to understand the tides; the rest of us need to understand the tides for different reasons. Knowing how tides work can help us avoid...
A study was conducted to identify geographical variation in loblolly pine bark and wood properties at the whole-tree level and to quantify the responses in whole-tree
bark and wood properties following contrasting silvicultural practices that included planting density, weed control, and fertilization. Trees were destructively sampled from
both conventionally managed...
The objectives of this study were to determine: 1)
differences in average wood quality and strength properties
of clear-wood specimens sampled from juvenile, transition,
and mature wood zones in Douglas-fir (Pseudotsuga menziesii
(Mirb.) Franco) trees from known forest sites; 2)
relationships among wood quality properties [specific
gravity (SG), rings per...
