Considerations for grading species combinations. General remarks on scenarios and requirements

Ridley-Ellis, Dan; Gil-Moreno, David; Harte, Annette M.

Abstract

This paper discusses the situations in which timber species might be combined in commercial combinations, and the considerations relating to strength grading work. It is expected that more species combinations will be developed in the years to come, as the timber value chain diversifies. However, it is not clear how the grading standards and associated procedures should best adapt to cover situations where there is no long-standing industry experience. This paper presents some considerations and examples, with the aim of assisting people doing grading work in taking informed, safe steps based on their knowledge of the resource. This paper gives examples from the European standards, and mostly temperate species, but the principles are general.
