Non Technical Summary
Sucessful accomplishment of work in this problem area will result in improved methods to grade wood materials. It will also provide information on uses of wood from trees that have been infected by invasivespecies.

Objectives Summary
The goals of this problem area are to develop technologies for characterizing the fundamental anatomical, physical, and mechanical properties and processing characteristics of wood.

Approach Summary
Planned attainments: 1) Information on the effectiveness of nondestructive assessment technologies for characterizing and sorting woody biomass; 2) Information on appropriate manufacturing technologies for wood products iinfected by invasive species; 3) Characterization of juvenile wood in lodgepole pine; 4) Advanced wood identification methodologies; 5) Identification methods for nano crystals from wood materials.
