The U.S. Department of Agriculture's Forest Products Laboratory has informed the American Lumber Standard Committee that it has completed its review of western grading agencies' monitoring data of Douglas Fir/Western Larch and found "no indication of a downward shift in allowable design properties" at this time. Other western species, including Spruce-Pine-Fir (South) and Hem-Fir, are to be sampled and tested. Such testing is conducted periodically to monitor for changes, to allow for timely actions to be taken, if needed, to support western lumber species.
