Help Stop the Spread of a New Species of Water Chestnut
Localities, pond management personnel and the general public are asked to look for a new species of Water Chestnut (genus  Trapa ) recently found in the Potomac Watershed. It has been spreading since 1995 so you may have already encountered this 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 in the Eurasian Water Chestnut. Reports of this or other invasive aquatic species can be made via a free phone app .  Water Chestnut (an annual) will sprout in May 2019, spread over the water surface and then flower and fruit by July; it drops seeds all season until it senesces after a hard frost. To stop the spread, management by harvesting the plants by mid –July is very successful in eradicating the plants but it may take several years of effort, if some seeds lay dormant.
Invasive Watch:
Spotted Lantern Fly
A potentially very serious pest of grapes, peaches, hops, and a variety of other crops, the spotted lanternfly (SLF), Lycorma delicatula, was detected in Frederick County, Virginia, on Jan. 10, 2018. It is important to look for it and report any finds. The spotted lanternfly has also been reported on a range of ornamentals around the home and in the landscape; in high numbers, the insect can become a nuisance pest to homeowners.
