Virginia DCR just published a new list of non-native invasive plants of the state!
Invasive plants can displace native plant species, reduce wildlife habitat and alter ecosystems. They threaten natural areas, parks and forests. In the United States, they cost an estimated $34 billion annually in economic loss.
Invasive, non-native plant species typically:
- Grow and mature rapidly.
- Produce seed prolifically.
- Are highly successful at germination and colonization.
- Outcompete native species.
- Are expensive to remove or control.
DCR Natural Heritage scientists used a risk-assessment protocol to determine an invasiveness rank for each species listed. Species were assigned a high, medium or low level of invasiveness in Virginia.
The list also includes species that may not be established in Virginia but are known to be invasive in habitats similar to those found here. These are referred to as “early-detection” species. If they are discovered in Virginia, the goal for these species is eradication to prevent their establishment and spread. People who spot these in Virginia should notify DCR.
While the list is helpful to land managers and conservationists, home gardeners can use it to make wise decisions about landscaping. The list is for educational purposes only and has no regulatory authority.
