Plummers Island

[2] Scientific study of Plummers Island began in 1899, when botanist Charles Louis Pollard[3] formed the Washington Biologists' Field Club and began the search for a field camp near the club's Washington, D.C.

[5] A 2008 issue of the Bulletin of the Biological Society of Washington was dedicated to articles about the flora and fauna of the island.

[6] The study of the island's three main plant communities, riparian, terrace, and upland forest,[7] 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.

In September 2017, Maryland Governor Larry Hogan announced plans to widen Interstate Highways I-270 and I-495 (Capital Beltway) with toll-funded express lanes; planned, built, and operated through a public-private partnership (P3).

If implemented, the highway expansion would fragment Plummers Island, which is located immediately downstream of the bridge.
