NZJFS - Volume 41 (2011)

This year is special for the New Zealand Journal of Forestry Science as 2011 is the fortieth anniversary of the Journal. This milestone is being marked by this year’s volume (41) having a ruby banner on the cover, a foreword from the chairman of Scion’s board of directors, Tony Nowell, a review on the history of the Journal and a retrospective, which will look back over the last forty years of forestry research in New Zealand. Volume 41 includes a special supplement of papers presented at the Fifth Meeting of the IUFRO Working Party S07-02-09, Phytophthora Diseases in Forests and Natural Ecosystems held in New Zealand during March 2010.
Overall, the scope of the Journal continues to cover the breadth of forestry science. Plantation forestry remains a particular focus but manuscripts on a wide range of forestry topics, such as tropical species, climate change, and policy will also be considered.

  • Meta-analysis of racial variation in Eucalyptus nitens and E. denticulata

    Hamilton, M. G., Dutkowski, G. W., Joyce, K. R., & Potts, B. M.
    Hamilton et al. (pp. 217-230) reviewed data from 85 southern hemisphere E. nitens/E. denticulata field trials to investigate racial (among population groups) genetic variation in growth, wood-property, tree-architecture, fitness and morphological/developmental traits. Significant differences among races were detected.

  • Predicting the severity of Dothistroma needle blight on Pinus radiata under future climate in New Zealand

    Watt, M. S., Palmer, D. J., & Bulman, L. S.
    Watt et al. (pp. 207-215) predicted possible changes in severity of Dothistroma needle blight over the next eighty years using a range of climate scenarios. Their results suggest that climate change is likely to have a significant effect on severity of Dothistroma needle blight over the long term.

  • Determining an optimal model for processing lidar data at the plot level: results for a Pinus radiata plantation in New South Wales, Australia

    Stone, C., Penman, T., & Turner, R.
    Stone et al. (pp. 191-205) collected airborne lidar and plot-based data from a radiata pine plantation in New South Wales, Australia. They extracted a series of area-based lidar metrics and these modelled against mean tree height, stem density, basal area and stand volume using various modelling techniques. The best models were used to produce prediction maps of these four inventory attributes. These results support the operational inclusion of airborne lidar data within P. radiata resource inventory systems.

  • Planted Forest Carbon Monitoring System - forest carbon model validation study for Pinus radiata

    Beets, P. N., Kimberley, M. O., Paul, T. S. H., & Garrett, L. G.
    Beets et al. (pp. 165-177) empirically validated the accuracy and precision of carbon stock and change estimates and predictions from the Forest Carbon Predictor model. Total carbon stock estimates at the inventory date and stock change projections over a 5 year interval are expected to average within 5% of actual values.

  • Preliminary screening of herbicide mixes for the control of five major weed species on certified Pinus radiata plantations in New Zealand.

    Rolando, C. A., Gous, S. F., & Watt, M. S.
    Rolando et al. (pp. 165-177) conducted a pot trial to test for a combination of herbicides as potential replacements for hexazinone and terbuthylazine. Suitable alternatives needed to be effective against a wide range of weeds while having low phytotoxicity to Pinus radiata. The results indicated that haloxyfop, clopyralid, triclopyr and picloram are potential replacements for the control of fogg grass, pampas, broom and gorse during year one.

  • Survival and growth to age 8 of four Populus maximowiczii × P. nigra clones in field trials on pastoral hill slopes in six climatic zones of New Zealand.

    McIvor, I. R., Hedderley, D. I., Hurst, S. E., & Fung, L. E.
    McIvor et al. (pp.151-163) trialled four experimental Populus maximowiczii × P. nigra clones in six different climatic zones. The results suggest that these clones are particularly suitable for colder sites subject to severe winter frosts and to warmer sites with regular rainfall, where their high rust resistance is an advantage. These clones also showed a high tolerance to wind. They are less suited to sites prone to salt spray and to summer drought.

  • Characterisation of within-tree and within-ring resin-pocket density in Pinus radiata across an environmental range in New Zealand.

    Watt, M. S., Kimberley, M. O., Downes, G. M., Bruce, J., Jones, T., Ottenschlaeger, M., Brownlie, R., Xue, J., Leckie, A. C., & Smaill, S. J.
    Watt et al. (pp.141-150) found differences in the frequency and distribution of type-1 and type-2 resin pockets within Pinus radiata trees.

  • Spatial description of potential areas suitable for afforestation within New Zealand and quantification of their productivity under Pinus radiata

    Watt, M. S., Palmer, D. J., & Höck, B. K.
    Using spatial data sets, Watt et al. (pp. 115-129) developed three potential afforestation scenarios for New Zealand that targeted non-arable land. Compared to the current plantations, at the national level, 2 to 6% increases in 300 Index were predicted for areas established under these three scenarios.

  • Overcoming the challenges of family and genotype representation and early cell line proliferation in somatic embryogenesis from control-pollinated seeds of Pinus radiata

    Hargreaves, C. L., Reeves, C. B., Find, K. I., Gough, K., Menzies, M. I., Low, C. B., & Mullin, T. J.
    Hargreaves et al. (pp. 97-114) tested improved methods for initiation of embryogenic cell lines developed with open-pollinated seeds, on control-pollinated radiata pine seed. Peak initiation rates of 70% for all families were equivalent to those achieved previously with open-pollinated seed. Significant improvements were made in early cell line proliferation of initiated cell lines for control-pollinated seed compared with open-pollinated seed. These successes should have positive applications to commercial clonal forestry operations.

  • Carbon accumulation in two Pinus radiata stands in the North Island of New Zealand

    Oliver, G. R., Beets, P. N., Pearce, S. H., Graham, J. D., & Garrett, L. G.
    Oliver et al. (pp. 71-86) measured carbon stocks in two Pinus radiata stands (Kinleith and Tarawera) in the North Island of New Zealand. Mean weighted carbon concentration of all mid-rotation above-ground live tree components plus attached dead branches was 51.4 and 52.0 g/100 g of dry matter at Kinleith and Tarawera, respectively, suggesting that post-1989 Pinus radiata plantation carbon stocks in New Zealand may be underestimated using the Intergovernmental Panel on Climate Change default value of carbon concentration as 50% of dry matter.

  • Alternatives to Pinus radiata in the New Zealand high-country: early growth and survival of P. radiata, P. attenuata and their F1 hybrid.

    Dungey, H. S., Low, C. B., Ledgard, N. J., & Stovold, G. T.
    Dungey et al. (pp. 61-69) tested Pinus attenuata × P. radiata hybrids and their open-pollinated pure-species controls across three trial sites in the South Island of New Zealand. They concluded that P. attenuata × P. radiata hybrids offer a real alternative to pine species that are prone to spreading in the New Zealand high country.

    Cown, D. J., Donaldson, L. A., & Downes, G. M.
    Cown et al. (pp. 41-60) review the types and occurrence of resin features in radiata pine. They discuss possible causes for the formation of resin features and links between external log characteristics and resin defects in wood.

  • Determining profitability for Ngati Whakaue Tribal Lands Inc. farms by developing a sustainable land management plan.

    Chikumbo, O., Mitchell, H., & Valance, R.
    Chikumbo et al. (pp.3-40) evaluated sustainable development of three New Zealand farms by selecting a range of land use and management alternatives over a specified period of time. They used a systems-approach framework in order to simultaneously determine optimal financial, social and environmental objectives. Positive results were obtained which indicate that a systems-approach framework could be successfully applied to resolving other complex land use situations.
