WIS-FACW
Wetland Indicator Status - FACW
Wetland Indicator Status (WIS) is a national list measuring the likelihood that a plant species would be found naturally occurring in a wetland environment (meaning an area characterized by flooding or saturation of soil permanently or seasonally) versus an upland environment (an area that almost never experiences saturated soils). Status may vary across regions. Our information is for the Midwest and Eastern Mountains and Piedmont regions that cover the Ohio River watershed in Ohio.
FACW - Facultative Wetland
Usually found in wetlands, but occasionally found in a non-wetland, plants with FACW status may benefit from seasonal flooding or the extra water collection of low spots in the landscape. They may not tolerate prolonged periods of drought without supplemental watering.
