An invasive species is not native to an environment and whose introduction causes or is likely to cause harm to the local economy, environment, or human health.
Many non-native species, including fruits, vegetables, field crops, livestock, and domestic animals, are essential to our economy and lifestyle. Most non-native species are not harmful and may provide economic benefits.
Invasive species cause harm when they out-compete native species by reproducing and spreading rapidly in areas with no natural predators, changing the balance of the ecosystems.
