The Riverhead factor -- a practical view of wood density

The article cites anecdotal evidence on the factors that impact wood density based on observations of forests in the Auckland, New Zealand region, including Riverhead Forest and the area midway between Whangarei and Dargaville. Traditionally, a good site, a vigorous plant and a silvicultural regime sensitive to rapid growth were considered essential in producing exceptional quality wood, a view upheld in existing guidelines on growing New Zealand radiata pine. Anecdotal evidence collected from large scale operations point out that fast grown trees do not perform well in density testing regardless of geographical location, slower growing trees as a result of site factors or silvicultural practices have a sound density profile and individual forest variability can be quite large.

    The sound speed of wood is related to important wood quality properties such as the microfibril angle of the S2 layer in the cell wall, stiffness, and shrinkage propensity. Measuring the sound speed of seedling stems has benefits to the forestry industry, potentially enabling early selection of...
