What do you mean it "was found to be invasive"?
Crown Vetch is a non-native plant that was introduced to North America and used for erosion control. What I mean is that after Crown Vetch was used as a ground cover for several years, the plant was found to have a negative impact on native plant species, crowding them out and eliminating them from the area.
Member bcp provided some good information.
The text below is from the USDA Forest Service. http://www.na.fs.fed.us/fhp/invasive_plants/weeds/crown-vetch.pdf
Distribution: This species is reported from states shaded on Plants Database map. It is reported invasive in CT, IN, KY, MD, MI, MO, NC, NJ, OR, TN, VA, and WI.
Ecological Impacts: Crown vetch is a serious management threat to natural areas due to its seeding ability and rapid vegetative spreading by rhizomes. This aggressive exotic is now widespread along roadsides and natural areas. It becomes problematic when it invades into natural areas, such as grassland prairies and dunes, where it works to exclude native vegetation by fully covering and shading native plants. It can climb over small trees and shrubs, and eventually form large single-species stands.
