Help Stop the Spread of a New Species of Water Chestnut Water chestnut. Photo from MISC, Maryland Invasive Species Council Be on the lookout for a new species of water chestnut (genus Trapa) (http://mdinvasives.org / iotm/june-2018/) found in the Potomac watershed, Trapa bispinosa Roxb. var. iinumai Nakano. It has been spreading since 1995 and is floating aquatic vegetation growing over the surface of a pond, lake or other fresh waterbody. This species is identified by the seed cases having two spines instead of four found on Trapa natans. Report all invasive aquatic species to the US Geological Survey’s Nonindigenous aquatic species website (https://nas.er.usgs.gov / SightingReport.aspx). Water chestnut (an annual) sprouts in May, spreads over the water surface and then flowers and fruits by July. It drops seeds all season until it senesces after a hard frost. To stop the spread, management by harvesting the plants by early July is very successful in eradicating the plants, but it may take several years of effort, if some seeds fall before the plants are harvested or lay dormant in the current year and sprout in a later year. |
