Sampling Plantation Eucalypts for Wood and Fibre Properties
By: GM GM Downes, IL IL Hudson, CA CA Raymond, GH GH Dean, AJ AJ Michell, LR LR Schimleck, R R Evans, A A Muneri
Written to help the forest industry assess wood quality by using non-destructive samples taken from specific points within a tree.
This book was written to help the forest industry assess wood quality by using non-destructive samples taken from specific points within a tree. It is the first compilation of research data on sampling of eucalypts, describing new methods and tools for rapid and cost-effective analysis. + Full description
The book provides information needed to design a sampling program, obtain and process wood samples, and shows how to relate the data to an average tree value.
