Herbaceous Plants λλ
Wetland Indicator reflects the estimated probability of the species being found in a wetland setting vs. non-wetland setting. OBL (Obligate Wetland, >99% probability) and UPL (Obligate Upland, <1% probability) represent the extremes. FAC (Facultative, 34-66%) indicates roughly equal probabilites of finding the species growing naturally in a wetland or non-wetland setting. FACW (Facultative Wetland, 67-99%) and FACU (Facultative Upland, 1-33%) indicates a bias toward one setting. NI indicates insufficient data to classify the species.
