Wetland Indicators
OBL – Obligate Wetland species Plants that occur almost always (estimated probability >99%) in wetlands, under natural conditions.
FACW – Facultative Wetland species Plants that usually occur in wetlands (estimated probability 67% - 99%), but occasionally are found in non-wetlands.
FAC – Facultative species Plants equally likely to occur in wetlands or non-wetlands (estimated probability 34%-66% in wetlands).
FACU – Facultative Upland species Plants usually found in non-wetlands (estimated 67%-99%), but on occasionally found in wetlands (estimated: 1%-33%).
UPL – Obiligate Upland species Plants almost always found in non-wetlands (estimated probability > 99%).
