“…8.1) provide a visual comparison c Although emergent marsh Carex biomass and total biomass were marginally non-significant after theŠidák correction was applied, individual comparisons were made because of the importance of biomass to ecosystem function d Submersed aquatic vegetation biomass scale 1 = 0 %; 2 = 1-5 %; 3 = 5-25 %; 4 = 25-75 %; 5 > 75 % e The Robel height value equals the lowest height that is not completely obscured by vegetation when viewed from a distance of 4 m with the viewer's eyes located at 100 or 150 cm above ground; the higher the number, the greater the above-ground vegetation structure. Robel height values are correlated significantly with above-ground biomass in bitumen region mineral wetlands (Raab et al 2013) Table 8.1) sites than near OSPA sites. The marsh portions of REF wetland sites tended to be larger than those of OSREF sites, which in turn were larger than those of OSPA sites.…”
