Other details:  Published 2011. Hardcopy is available.


This extension note outlines a new standard coding system for site series introduced or revised after March 31, 2010. In addition, coding systems for site units representing non-forested ecosystems and for immature (seral) ecosystems are presented.

Four changes are outlined:

1. Site series in reclassified subzones/variants will be identified by a three-digit rather than two-digit code to reflect classification version.
2. The order in which site series are numbered has been modified.
3. Seral ecosystem units have been assigned a formal coding format.
4. The system for coding wetlands has been extended to other nonforested ecosystem units.
