Data on Physical, Chemical, and Biological Characteristics of Hydrilla Beds, Mixed Vegetation Beds, and Unvegetated sites in the Tidal Potomac River, Maryland and Virginia 1987

Published: January 01, 1987

This report summarizes data on the physical, chemical and biological characteristics of three types of sites--submersed aquatic vegetation beds dominated by Hydrilla Verticillate, beds containing a diversity of submersed macrophyte species, and sites without vegetation.  The data were collected diurnally and seasonally in the tidal Potomac River during 1987.  Plant species were identified and dry weight determined for samples from each vegetated site.Algal photosynthetic rate and bacterial zooplankton and vegetation-associated invertebrates were sampled and enumerated.
