7. Objective - Learner will gain knowledge and understanding of the properties of hardwood and softwood timbers HARDWOODS Hardwoods Hardwood trees are usually deciduous with broad leaves. They grow best in warm, wet (tropical)areas. They include the densest, strongest and most durable timbers. But NOT all hardwoods are hard, e.g. balsa wood. The cheaper hardwoods are approximately equal in cost to expensive softwoods. Hardwood List: Ash, Beech, Elm, Mahogany, Chestnut, Maple, Teak, Walnut & Oak. To name but a few

9. Objective - Learner will gain knowledge and understanding of the properties of hardwood and softwood timbers SOFTWOODS Softwoods Softwood trees are evergreen with pine needles and cones. They grow best in cold, dry climates. They are NOT all soft, e.g. yew. Softwoods comprise about 75% of timber used in the UK. Softwood List: Cedar, Douglas Fir, Larch, Pine, Yew & European Redwood Remember there are LESS softwoods than hardwoods.
