Strength class of minor conifer species, as estimated from log acoustic measurements, small-clear data and knowledge of wood property variation (2014)
Presentation / Conference Contribution
Gil-Moreno, D., Ridley-Ellis, D., & McLean, J. P. (2014, May). Strength class of minor conifer species, as estimated from log acoustic measurements, small-clear data and knowledge of wood property variation. Presented at Experimental Research with Timber: Cost action FP1004

It is well known that wood properties vary from species to species. Additionally, trees grow wood in response to their requirement to grow in a certain environment. Therefore, timber properties also vary by region, by forest practice, and by the chan...
