Emersed plant biomass

Emersed plant biomass (as used by Florida LAKEWATCH) is the average weight of fresh, live emergent aquatic plants growing in one square meter of a lake's bottom area. The measurement of average emersed plant biomass in a waterbody is one of several measurements that can be used to assess a waterbody's overall biological productivity.

IN FLORIDA
Average emersed plant biomass in Florida lakes generally ranges from 0 to 27 kg wet wt/m².

in biologically less productive lakes (oligotrophic lakes), the average emersed plant biomass is about 2.5 kg wet wt/m2;
in moderately productive lakes (mesotropic lakes) the average emersed plant biomass is about 3.0 kg wet wt/m2;
in highly productive lakes (eutrophic lakes) the average emersed plant biomass is about 3.5 kg wet wt/m2;
in the most highly productive lakes (hypereutrophic lakes) the average emersed plant biomass is about 4.0 kg wet wt/m2.
