Table 1. Wetland zones related to the ordinary high-water mark (OHWM) across which vegetation sampling was stratified.

Zone	Description
Wetland buffer (WB)	Upland area slightly above the OHWM. Soils were not hydric, and indicative of upland hydrology. Generally perched 0.2 m above the OHWM except where higher elevation microtopography existed
Upper wetland (UW)	The area that generally captured the OHWM and adjacent areas, including wetland soils, but generally inundated by <15 cm of water for a portion of the year
Lower wetland (LW)	Emergent, low wetland area below the OHWM, where standing water persists during a large portion of the growing season, often at depths >15 cm
