Virginia Invasive Species

What Are Invasive Species? 

Invasive species--such as spotted lanternfly, feral swine, wavyleaf grass, and the emerald ash borer--damage forests, grasslands, marshes, and farmlands. They may also cause harm to humans. Invasive species are non-native weeds, insect pests and other organisms introduced intentionally or accidentally by people who move them from their native range. 

In the United States, economists estimate that more than $120 billion are lost annually to damages associated with invasive species. Invasive species threaten native plants and animals and their habitat in forests, marshes, and other natural areas.


zebra musselsA new aquatic invasive plant is spreading rapidly across ponds and other waterbodies in northern Virginia. Recently, it was found in Charlotte County, Virginia, and Greenbelt, Maryland. A cousin of the infamous European water chestnut that once choked the Potomac River, two-horned trapa infests freshwater ponds, lakes, and slow-moving waterways.
