Appendix C: Revised PFCA Checklist Scoring Definitions

A score of 1 indicates that extensive, geomorphically inconsistent (GI) alterations of an ecosystem characteristic have occurred, and a score of 5 indicates that the characteristic is geomorphically consistent (GC) and equivalent to that found in natural settings.  An asterix (*) indicates that the question answered includes the use of the in-office worksheet (Appendix A). Note that work space is provided in this Appendix for composite scores for some questions in the Riparian Vegetation section. Some questions may be non-applicable (n/a) or unknown (unk): “n/a” and “unk” scores do not contribute to the average section score.
