New Invasive Alert– Java Dropwort (Oenanthe javanica)

Java Dropwort (Oenanthe javanica) has been found in Fairfax County , Virginia . The population was found growing along a storm water management pond and in silt deposits in a drainage canal going to the pond. The canal goes directly into Huntley Meadows Park which has a large, sensitive wetland area.
It is an emergent plant that seems to tolerate a range of conditions. The Fairfax County Park Authority is looking for any additional information on this species, specifically how to eradicate it. The population was still green in November, even when it was partially frozen under ice in the drainage canal. The Fairfax County Park Authority is also interested in other areas this species has been found. It has just been added to the EDDMapS drop down menu so please mark the location if you have seen this species in your area and report it in EDDMapS.
