ASSESSING THE HISTORICAL DISTRIBUTION OF PODOSTEMUM CERATOPHYLLUM MICHX., A FOUNDATION SPECIES OF EASTERN NORTH AMERICA RIVERS
Podostemum ceratophyllum Michx. is a torrenticolous riverine macrophyte with a range that extends from Georgia to Canada in eastern North America. Podostemum can have a large influence on benthic ecology by substantially increasing habitat complexity, facilitating increased macroinvertebrate biomass, and possibly, boosting the local abundance of fish and large body consumers.
Podostemum, however, appears to be declining throughout much of its range but historical records of the plant’s occurrence are incomplete leaving uncertainty in what rivers and watersheds the plant historically occurred in. Currently six northeastern states list Podostemum as threatened, endangered, or a species of special concern but the causes of decline are unclear. Conservation and restoration efforts focused on Podostemum will require a more detailed understanding of the plant’s historical biogeography.
We reviewed herbarium records, published literature, and state agency databases to create distribution maps of Podostemum in eastern North America. Our data provide new insight into changes in the plant’s presence in eastern rivers and support the conclusion that Podostemum was historically present in the major river basins (HUC 6) throughout Appalachia and the Piedmont region. Ongoing work is investigating stressors influence on Podostmeum growth and survival.
