Research

The ecology and restoration on submersed aquatic vegetation (SAV) is my main research focus.  

Historically 16 species of SAV were commonly found in the Chesapeake Bay or nearby rivers.  Following the declines on the 1970’s, Bay grasses have made a slow come-back over the past 20 years.  However, in the mid-salinity regions of Chesapeake Bay, there is low species diversity when compared to pre-decline years. Approximately 90% of the SAV coverage in the Choptank River is one species, Ruppia maritima (Orth et. al, 1984-2001).
Our research efforts have centered on the theme that existing Ruppia maritima (Widgeon grass) beds can serve as nursery areas for the restoration and survival of more desirable and more stable SAV species (Potamogeton perfoliatus or redhead grass and Stuckenia pectinata or Sago pondweed). SAV

Our restoration efforts have been successful in areas where existing R. maritima beds have served as nurse crops for other species of SAV.
