| 500 | 0 | |a In the natural forest a tree falls making a gap in the canopy and letting light in to the forest floor. In the clearing seedlings germinate and grow. They compete with each other for water, nutrients and space. In the struggle for life only one or two survive to reach the forest ceiling. Their early competition with other trees has ensured that their stems are straight and free of branches. Only when the crown has emerged above the forest canopy can it develop and allow the tree to grow to a large size. A mature tree contains a large volume of knot-free, high quality wood which we call clear wood. As the whole process takes several hundred years and we can't wait that long so we plant fast-growing introduced species mainly radiata pine which grow into large trees suitable for sawing in twenty five to thirty years. | |
