Nuisance species are non-native species (a.k.a. exotic, alien, or non-indigenous) that have moved outside their native range AND threaten native species or interfere with important commercial, agricultural, and recreational actives.
Natural “checks and balances” such as predators, parasites, diseases, and competitors may not exist outside of the native ranges for these species. This creates an environment where they can dominate and become “nuisances.”Native species are not used to living with these nuisance species and are not adapted to eat them or compete with them. This can quickly upset the natural balance of an ecosystem and create many negative impacts.
Nuisance species have major biological, economical, and aesthetic impacts on Kentucky.
Biological Impacts include the degradation of native habitats, reduced abundance of native species, and the loss of biodiversity on a global scale.

Economic Impacts include increased business costs due to interference with normal operations or infrastructure. In addition, tourism dollars are lost when recreational experiences such as hunting, hiking, fishing, swimming, and boating are no longer possible or pleasant.

Aesthetic Impacts are often seen with invasions by non-native species. This results in an inability for the citizens of Kentucky to enjoy and pass along their favorite fishing, hunting, and hiking areas to future generations.
