Hi Chris

The NCPTT has an article entitled "A Grading Protocol for Structural Lumber and Timber in Historic Structures" and a MS Access database at

http://ncptt.nps.gov/a-grading-protocol-...-2009-01/all/1/

The database is somewhat limited in the number of species covered but it may be useful in a site survey.

You may find a resource in the NCPTT since it is located in Louisiana.
