Aotearoa (New Zealand) has planted extensive industrial tree plantations (more than one and a half million hectares), mostly based on one exotic tree species: Pinus radiata. In recent decades planting clonal stock has become standard practice. Currently, more than 95% of new planting (this includes new afforestation and planting after harvest) is based on Pinus radiata clones, selected primarily for rapid growth (and thus reliance on fertilisers), tree form to maximise the amount of `clear' (knot free) wood, and qualities that suit industrial purposes.
