Windthrow
When trees are pushed over or uprooted by wind.
Wood
Wood consists of cellulose (40-45%) and hemicellulose (15-30%), which are both carbohydrates. Wood also contains up to 30% of complex high molecular weight poly-phenolic chemicals, including lignin. Lignin is an important component that gives wood its rigidity (and consequently allows plants made from wood reach a large size) and much of its durability.
Yield
The amount of wood recovered from an area of land in the forest, usually expressed as cubic metres per hectare (m3/ha).
