- 3. Trees – 2 groups • Coniferous • Softwood • Needle-like leaves • Deciduous • Hardwood • Broad leaves
- 4. Deciduous trees (hardwoods) • • • • • • • • • Produce hardwood timber Lose their leaves in autumn (except holly) Trunk divides to develop large branches Branches are larger and more irregular Broad leaves Seeds borne in nuts/berries Slow growing Wood is more valuable Wood is harder and more durable
- 5. Coniferous trees (softwoods) • • • • • • • • • • Produce softwood timber Evergreen (except larch) Straight trunk Smaller branches Needle-like leaves Seeds borne in pine cones Symmetrical in shape Grow quickly Wood is usually cheaper Wood is usually softer and less durable
