     The Forest Engineering Research Institute of Canada (FERIC) in 
     Pointe-Claire has a project to develop a fully-mechanized system for 
     selection harvesting of large tolerant hardwoods. One of the issues 
     with tolerant hardwoods is stem quality for veneer and sawlog 
     products, especially in relation to rot or defect content and location 
     in the stem. It has been suggested that it may be possible to mount 
     some sort of scanning device on a felling or processing machine to 
     detect and quantify rot before the processing phase.
     
     I would appreciate any update or recent reference on the use of such 
     technologies as ultra-sound, micro-wave, x-rays, gamme rays, 
     tomography, magnetic resonance or any other for detecting rot in 
     trees.
