Natural Timbers

Lumber - When a tree has been felled
Timber - Processed material
Wood - Material

Hardwoods

. Come from deciduous tress
. Deciduous trees loose leaves in autumn
. Oak is an indigenous tree (grows in England)
. Slow growing
. Examples: Ash, Oak, Beech, Teek, Walnut

Softwoods

. From coniferous trees (needles & cones)
. Fast growing
. Cheaper to buy because of shorter growing time (more can be cut down in the same time as hardwoods)
. Examples: Larch, Spruce, Scots Pine, Douglas Fir



A trees age can be worked out by counting the annual/growth rings in its trunk. Each ring represents a summer/winter. The winter rings are darker because of bark that grows to protect the tree from cold, causing less light to reach the trunk.

The FSC are an organization that make sure the wood that is imported is from a sustainable source, meaning that more trees are planted in the old trees place.
