USE THIS FILE TO INTERPRET THE FRESHWATER WETLANDS TYPE FROM THE ALPHA-NUMERIC

LABEL CONTAINED IN THE COWARDIN ATTRIBUTE FIELD . THE TABLE IS FROM

THE FIRST LETTER IN THE LABEL IDENTIFIES THE ECOLOGICAL SYSTEM.

IF THE LETTER IS FOLLOWED BY A NUMBER, THE NUMBER IDENTIFIES THE SUBSYSTEM.

NOTE THAT THE PALUSTRINE SYSTEM (P) HAS NO SUBSYSTEMS.

THE NEXT TWO LETTERS WOULD IDENTIFY THE CLASS OF THE WETLANDS.

THE NEXT NUMBER WOULD IDENTIFY THE SUBCLASS.

ANY SPECIAL MODIFIERS FOR THE AREA WOULD BE IDENTIFIED BY THE LETTERS

AT THE END OF THE LABEL.

FOR EXAMPLE, THE LABEL R4US2d WOULD BE INTERPRETED AS:

RIVERINE (R) SYSTEM

INTERMITTENT (4) SUBSYSTEM

UNCONSOLIDATED SHORE (US) CLASS

SAND (1) SUBCLASS

PARTIALLY DRAINED/DITCHED (d)

NOTE THAT MIXTURES OF TYPES CAN ALSO BE IDENTIFIED WITH THE TWO MAJOR

TYPES SEPARATED BY A '/' AS WITH PSS4Bh/PFO4Bh.
