Five species of freshwater triclad planarians were found on Plummers Island and the adjacent mainland property, Montgomery County, Maryland. One species (Dugesia [G.] tigrina) occupying the Potomac River and a tributary, is tolerant of degraded habitat. The other four occupy vernal pools (Hymanella retenuova and Phagocata velata) or spring-seeps (Phagocata morgani and Paraplanaria dactyligera) and appear to be indicators of high quality aquatic habitat. These five species represent 36\% of the total known Maryland fauna of 14 species.ABSTRACT Five species of freshwater triclad planarians were found on Plummers Island and the adjacent mainland property, Montgomery County, Maryland.
