Type: article
Abstract: Species and provenance trials of eucalypts planted in Northland between 1988 and 1993 included several provenances each of Eucalyptus fastigata Deane et Maiden, E. regnans F. Mueller, E. saligna Smith, E. botryoides Smith, E. grandis Hill ex Maiden, E. nitens (Deane et Maiden) Maiden, E. globulus Labill, and E. maidenii Labill. Trials were all located between Kaikohe and Dargaville (latitudes 35°31 ' to 35°48'), with two trials at Carnation Road and two at Walker Road (aged 11 and 9 years) and one of E. nitens only at Karaka Road. Trial designs were mainly 64-tree square plots with two to five replicates. Trees were assessed for breast height diameter over-bark, bole straightness, malformation, and crown health. Results were expressed as provenance and species means at each site, and also as basal area per hectare over-bark, volume per hectare under-bark, and frequencies of crop trees, mortality, and runts (suppressed sub-dominants). Eucalyptus fastigata at its single test site showed best growth and health of all species (mean annual increment (MAI) at Carnation Road averaged 52 m3/ha) but suffered some
