NZJFS - Volume 42 (2012)

The scope of the New Zealand Journal of Forestry Science covers the breadth of forestry science. Planted forests are a particular focus but manuscripts on a wide range of forestry topics, such as tropical species, climate change, and policy will also be considered.

  • Effect of seed source of Douglas-fir at high-elevation New Zealand sites: performance at age eight years

    Low, C. B.; Shelbourne, C. J. A. & Henley, D. G.
    Low et al. (pp. 161-176) found that the effect harsh climate on the growth of Douglas-fir at four South Island sites largely obliterated any provenance differences.

  • Reliability of increment core growth ring counts as estimates of stand age in totara (Podocarpus totara D.Don)

    Bergin, D. O., & Kimberley, M. O.
    Bergin and Kimberley (pp.131-141) tested the reliability of a method for estimating tree age by using growth-ring counts for totara stands of known age. The method tended to underestimate age in closed stands, and to overestimate the age of open-grown trees. Avoidance of sampling suppressed trees and rejection of core samples with indistinct latewood bands should decrease error and allow estimates of stand age to lie within 10 – 15% of actual age.

  • Impact of thinning and pruning on selected wood properties in individual radiata pine trees in New Zealand

    Grace, J. C., & Evans, R.
    Grace and Evans (pp.117-129) examined changes in wood density and microfibril angle in individual radiata pine trees in response to seven different pruning and thinning regimes. Severe pruning combined with extensive thinning resulted in an increase in wood microfibril angle around the time of thinning but younger wood was not influenced by historic silvicultural treatments.

  • Micropropagation of kauri (Agathis australis (D.Don.) Lindl.): in vitro stimulation of shoot and root development and the effect of rooting hormone application method

    Gough, K., Hargreaves, C., Steward, G., Menzies, M., Low, C., & Dungey, H. S.
    Gough et al. (pp. 107-116) have developed improved methods for the production of shoots and roots in micropropogated kauri embryos.

  • Lessons from the global financial meltdown: minimising risk by enhancing value creation in land and water management

    Chikumbo, O., & Payn, T.
    Chikumbo and Payn (pp. 91-105) compared three statistical-distribution models to assess risk management in New Zealand's land and water resources. All three models performed well. Expert judgement is a critical factor in the choice of appropriate model and in risk quantification.

  • Predicting the spatial distribution of Sequoia sempervirens productivity in New Zealand

    Palmer, D. J., Watt, M. S., Kimberley, M. O., & Dungey, H. S
    Palmer et al. (pp. 81-89) developed Site Index and 400 Index models for Sequoia sempervirens to assist in predicting spatial variation in productivity of this species across New Zealand.

  • Generic dose response curves for predicting effects of herbicides on weeds or sensitive plant species

    Richardson, B., Kimberley, M. O., & Watt, M. S.
    Richardson et al. (pp. 73-80) developed generic herbicide-plant dose-response curves using data from an existing dose-response database.

  • Predicting the severity of Cyclaneusma needle cast on Pinus radiata under future climate in New Zealand

    Watt, M. S., Palmer, D. J., Bulman, L. S. & Harrison, D.
    Watt et al. (pp. 65-71) predicted the possible severity of Cyclaneusma needle cast disease in New Zealand to 2090. They tested a range of current and future climate scenarios in an existing model of Cyclaneusma needle cast severity developed from an extensive empirical dataset.

  • Evaluation of an occlusion adjustment model for predicting hidden stems when using terrestrial laser scans in natural and plantation forests in Australia and USA

    Murphy, G.
    Murphy (pp.57-63) evaluated an occlusion adjustment model that can be used to predict stand-level tree count densities with minimal errors based on terrestrial laser scanning data.

  • Effect of boron application on tree form and growth in young Pseudotsuga menziesii trees at montane sites in the South Island of New Zealand.

    Davis, M., Henley, D., Coker, G., & Smaill, S.
    Davis et al. (pp. 47-55) found that stem malformation in young Douglas-fir trees at two sites was not due to boron deficiency.

  • Type 1 and 2 resin pockets in New Zealand radiata pine: how do they differ?

    Ottenschlaeger, M., Downes, G. M., Bruce, J., & Jones, T.
    Ottenschlaeger et al. (pp. 39-46) suggest that current distinctions drawn between different types of resin pockets actually represent a single developmental continuum with a common physiological cause.

  • Estimating carbon stocks in stands of Podocarpus cunninghamii in the eastern South Island high country of New Zealand

    Williams, A., & Norton, D. A.
    Williams and Norton (pp. 29-38) provide the first estimates of existing above- and below-ground carbon stocks in high country stands of Podocarpus cunninghamii and present a preliminary model of Podocarpus cunninghamii carbon sequestration rate.

    Mason, E. G., Sewell, A. C., & Evison, D.
    Mason et al. (pp. 25-28) tested the validity of a generalised individual-tree volume equation specifically for Nothofagus menziesii. The correlation between predicted and estimated volumes was 0.97.

    The quality and exportability of radiata pine logs can be adversely affected by burnt pine longhorn beetle infestation. Van Epenhuijsen et al. (pp. 15-23) found suitable conditions for storing eggs, for storing live adults, and for rearing larvae of this pest for use in fumigation trials.
