Wetland Indicator Status - OBL

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.

OBL - Obligate Wetland

Almost always found in a wetland. In the landscape, plants with OBL status generally do not tolerate drying out and must be thoughtfully placed. Special care may be needed if moisture conditions are not optimal.
