Wetland Indicator Status (US Fish and Wildlife 1996) was assigned to each plant species as follows: Obligate Wetland species (OBL) occur almost always (> 99%) in wetlands, Facultative Wetland species (FACW) usually occur in wetlands (67%-99%) but are occasionally found in non-wetlands, Facultative species (FAC) are equally likely to occur in wetlands or non-wetlands (34%-66%), Facultative Upland species (FACU) are only occasionally found in wetlands (1%-33%), Obligate Upland species (UPL) are almost always found in non-wetland areas, and No Indicator species (NI) are those taxa for which there is not enough information to determine their wetland status.
