Recent Detection and Spread of a new type of Trapa, an Invasive Aquatic Plant, in the Potomac River Watershed
A review of the information obtained from 2014 to 2018 on a new type of non-native water chestnut spreading in Virginia. How do we better reach out to stakeholders to inform them and encourage them to stop the spread of Trapa bispinosa? Are you aware of an existing federal or municipal program or a case study of the use of EDRR for species that threaten landscapes and aquatic areas?
Dr. Nancy Rybicki, USGS emeritus aquatic plant ecologist
In the past Dr. Rybicki conducted long term research projects on the increase of submersed aquatic vegetation abundance and diversity in the freshwater, tidal Potomac River during a time interval when water quality improved. Her education was in Environmental Science and she is an affiliate professor at George Mason University.
This plant is a non-native floating aquatic plant that was discovered in 2014 in the Potomac River watershed and has been spreading rapidly since. Currently, it is reported and verified to occur in small colonies in about 30 water bodies, mostly ponds, in several northern Virginia counties (see the USGS NAS database for more information). Immediate action is needed to control this plant before it expands throughout the watershed and causes significant ecological, economic and recreational impacts.
