A 2008 issue of the ''Bulletin of the Biological Society of Washington'' was dedicated to articles about the flora and fauna of the island. The study of the island's three main plant communities, riparian, terrace, and upland forest, documented 3,012 insect species in 253 families, in 18 orders: Collembola, Odonata, Dermaptera, Blattodea, Phasmatodea, Orthoptera, Psocoptera, Thysanoptera, Hemiptera, Neuroptera, Megaloptera, Coleoptera, Mecoptera, Trichoptera, Lepidoptera, Diptera, Siphonaptera, and Hymenoptera. Another of the studies reported 19 species of freshwater mollusks (7 bivalves, 12 gastropods) in the island's immediate area, bringing the total known for the Middle Potomac River to 42 species.〔Timothy A. Pearce & Ryan Evans. 2008. Freshwater Mollusca of Plummers Island, Maryland. ''Bulletin of the Biological Society of Washington'' 15: 20-30.〕 A periodically updated checklist which includes all the vascular plants of the flora, including ferns, fern allies, gymnosperms, and flowering plants, that have ever been reported growing in the wild on the island and its adjacent mainland, totals 885 plant species, of which 704 are native, and 181 naturalized.〔Stanwyn G.
