Growth of native trees in plantations.

Abstract

Small plantations of native tree species have been established in New Zealand since around the beginning of the twentieth century. In 1985-86 staff at the Forest Research Institute carried out a survey to locate plantations of native species. Questionnaires (species planted, type of planting stock, date of planting, size of plantation, spacing of trees, reason for planting, establishment methods, site description, and comments on tree survival, growth and form) were sent to over 200 individuals and organizations known to have planted native trees. Height and diameter measurements at 20, 40 and 60 yr old are tabulated for 8 conifer species (Agathis australis, Dacrydium cupressinum, Podocarpus totara, Dacrycarpus dacrydioides, Phyllocladus trichomanoides, Prumnopitys taxifolia, P. ferruginea and Libocedrus plumosa) and 12 broadleaved species (Nothofagus fusca, N. solandri, N. menziesii, Vitex lucens, Litsea calicaris, Alectryon excelsus, Laurelia novae-zelandiae, Beilschmiedia taraire [B. tarairi], Knightia excelsa, Nestegis cunninghamii, Corynocarpus laevigatus and Metrosideros excelsa).
