What is an invasive species?

Invasive species are non-native species that can cause harm to the environment, the economy or to human health.
 Invasives come from all around the world. As international trade increases, so does the rate of invasive species introductions.

Why are invasive species a threat?

Invasive species threaten nearly every aspect of our world and are one of the greatest threats to New York's biodiversity.
 They cause or contribute to:
  • Habitat degradation and loss
  • The loss of native fish, wildlife and tree species
  • The loss of recreational opportunities and income
  • Crop damage and diseases in humans and livestock

Invasive Species Regulation

 A regulation came into effect on Mar. 10, 2015 regulating the possession, transport, importation, sale, purchase and introduction of select invasive species.
Economic Impact: 
Recent estimates conclude that invasive species cost the U.S. at least $137 billion per year. In addition to reducing the diversity of native plants and animals, invasive plants have the potential to impact forest regeneration, agriculture, and recreation.
