Abstract: A clear-felling harvest of a 29-year-old plantation in Kaingaroa Forest removed 85% of the stem material. The relatively lower nutrient concentrations in larger diameter logs meant that 77 and 84% of total nutrients in the stems were removed in harvesting. The effects of a range of harvesting intensities on nutrient removal from the site can be estimated from the relationship between utilization limit nutrient content and the total amount of nutrients in the stand.
