Resumen
Eucalyptus nitens is a rapidly growing species which was little planted in New Zealand due to severe defoliation caused by a beetle, Paropsis charybdis. In 1987 ensis (formerly Forest Research) released a parasitic wasp, successfully controlling the pest. Since then, E. nitens has been planted in the Bay of Plenty/Taupo and Southland regions for local kraft pulp and export chip respectively. There may be a wider role for the species in New Zealand if it can be demonstrated that it can produce quality solidwood products. Ensis genetics and the Eucalypts Cooperative is collecting growth and wood quality information from most regions of the country and performance is being monitored in plantations. An Ensis sawing trial based on a 30-year-old stand showed there were some problems with sawn timber such as internal checking. The opportunity to extend the research to trees from another stand was provided by a unique stand of pruned fifteen-year old E.nitens in an ensis trial at Golden Downs Forest, Nelson. Whilst the butt logs were suitable for sawing, a structural product, laminated veneer lumber (LVL) was considered a likely appropriate use of the heavily branched second logs. This note summarises the main results of the LVL study.
