This introductory report was produced after increasing interest in Paulownia for biomass, principally as fuel for energy generation.
Under a biomass system Paulownia can be planted at high density as they are harvested young and do not need the canopy space required for the trunks to become thick as in timber plantations. Optimum planting density will depend on the lignification required which will dictate the age of harvest. If you wish to harvest soft material with a 1-2 year rotation you may plant up to a massive 10,000 trees per hectare. The model in this report assumes a requirement for woody biomass which can be produced on a 2-3 year rotation at 3,000 stems / ha.
