| Obligate Wetland Plants | OBL |
Plants that occur almost always (estimated probability >99%)
in wetlands under natural conditions, but which may also
occur rarely (estimated probability <1%) in non-wetlands.
Examples: smooth cordgrass, bald cypress |
| Facultative Wetland Plants | FACW |
Plants that occur usually (estimated probability >67% to
99%) in wetlands, but also occur (estimated probability 1%
to 33% in non-wetlands). Examples: green ash,
Red-osier dogwood |
| Facultative Plants | FAC |
Plants with a similar likelihood (estimated probability 33%
to 67%) of occurring in both wetlands and non-wetlands.
Examples: honey locust, common greenbrier |
| Facultative Upland Plants | FACU |
Plants that occur sometimes (estimated probability 1% to
<33%) in wetlands, but occur more often (estimated
probability >67% to 99%) in non-wetlands. Examples: red
oak, tall cinquefoil |
| Obligate Upland Plants | UPL |
Plants that occur rarely (estimated probability <1%) in
wetlands, but occur almost always (estimated probability
>99%) in wetlands under natural conditions. Examples:
shortleaf pine, soft brome |
