Timber properties of noble fir, Norway spruce, western red cedar and western hemlock grown in Great Britain (2016)
Report
Gil-Moreno, D., Ridley-Ellis, D., & McLean, P. (2016). Timber properties of noble fir, Norway spruce, western red cedar and western hemlock grown in Great Britain. Great Britain: Forest Research

The softwood processing sector in Great Britain has been built around the use of a very small number of timber producing species – predominantly Sitka spruce. The recent increase in outbreaks of host-specific tree pests and diseases has led to an int...
