The wetland Indicator status breaks down species in the following categories: Obligate-wetland (OBL), facultative-wetland (FACW), facultative (FAC), facultative upland (FACU) and obligate-wetland (UPL). The p values are statistical results testing for differences between all exclosed and grazed sites combined.
