National Invasive Species Information Center (NISIC)

The gateway to invasive species information; covering federal, state, local and international sources.

Invasive species are plants, animals, or pathogens that are non-native (or alien) to the ecosystem under consideration, and whose introduction causes or is likely to cause harm. Learn what determines if a species is invasive.

Asian Longhorned Tick

Potential vector of several human and animal diseases present in the United States (CDC 2018)
Soybean Rust

Disease of soybean and other legumes; P. pachyrhizi can reduce soybean yields up to 80% (Schnepf 2005); P. meibomiae is less virulent but has a broader host range (CABI)
Golden Mussel

Threatens native biodiversity, suffocate and starve out native bivalves and produce macrofouling in water systems (Global Invasive Species Database 2005)
Asian Citrus Psyllid

Damages citrus plants by feeding on sap; serves as a vector for citrus greening disease, which causes a decline in citrus production. (Grafton-Cardwell et al. 2006)
