Graminoids and forbs with FACU and FAC wetland indicator status tended to increase in abundance as degree of bank incision increased.
The significant decline in FACW/OBL species in response to increased BHR is another indication of a functional shift from hydrophyte-dominated to FAC and FACU vegetation assemblages.

Frogfruit has a wetland indicator status of FAC+ (about 60% chance of occurring in a wetland), Johnson grass is FACU
(20% chance of occurring in a wetland), and barnyard grass is FACW (80% chance of occurring in a wetland), averaging a little more than 50% chance of occurring in the wetland.
Also, the upland section of the black spruce stand, where hydric soils and hydrology indicators were lacking, had an increase in FAC, FACU
, and UPL species that resulted in an increase of their PI values.
If the FACU
receives a signal from any device, it will transmit to the remote
