Invasive Species

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

Rapid Response for Invasive Species: Framework for Response

DEC Policy Available for Download

This program policy is intended to serve as an aid to resource managers who are responsible for responding to newly discovered invasive species infestations. Early detection of new invasions is critical to any rapid response. The process that we have selected ensures that managers give attention to all of the necessary components of an effective response: coordination, communication, public outreach, planning, science, information management, laws and regulations, resources and logistics. Our experiences with snakehead fish, chronic wasting disease, hydrilla, oak wilt, Asian long horned beetle, and emerald ash borer in New York State have been used to help develop and refine this framework.
