Abstract
Data from 55 Florida lakes were used to demonstrate that the maximum measured standing crop of emergent, floating-leaved, and submersed plants can be used to provide a simple characterization of macrophyte standing crops in the littoral zones of lakes. The maximum standing crop was strongly related to the mean standing crop of emergent, floating-leaved, and submersed macrophytes, and there was also a strong relationship when data from all plant types were combined. The analyses suggest that the maximum standing crop of aquatic macrophytes can provide useful information to characterize macrophyte standing crop in the littoral zone of lakes.
