Wood Quality Consortium

Wood Quality Consortium Summary

Description

  • Research and outreach into wood and fiber quality of plantation southern pine
  • Founded in 2000 as a cooperative between industry, USDA Forest Service, and UGA

Objective

The objective of the Wood Quality Consortium is to improve wood and fiber production, procurement, and utilization of southern pine plantations by providing data, prediction tools, analyses, and field methods for incorporating wood and fiber properties into timber growing, procurement, and manufacturing decisions.

Current Projects

  • Linking forest management and genetic improvement to wood and lumber properties
  • Characterization of fiber properties collected across South wide baseline study
  • Modeling wood quality responses to silviculture, environmental variables, and soil

Databases

  • South wide baseline study of specific gravity of loblolly pine
  • Ring-by-ring, disk, tree, stand, and regional variation in specific gravity
  • Specific gravity responses to intensive culture:  initial spacing, thinning, fertilization, vegetation control, advanced genetics

Capabilities

  • Wood and fiber property modeling
  • Forest and mill sampling for wood and fiber properties
  • Sample preparation
    • Wood-Mizer sawmill and fully equipped woodshop
    • Dry kiln and ovens
    • Chipper and chip sorters
    • Pulping laboratory
    • Soxhlet extraction
  • Lab analyses for wood properties
    • Wood and bark moisture content and specific gravity
    • Ring-by-ring wood density (X-ray densitometry)
    • Ring-by-ring acoustic velocity
    • Ring-by-ring fiber properties (fiber analyzer)
    • Ring-by-ring anatomical properties (custom fiber analyzer)
    • Wood stiffness (standing tree, logs, lumber)
    • Wood stiffness and strength (static bending, tension)
