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
  • Risks to public safety

Managing Invasive Species

DEC's Role

To combat the impacts of invasive species, DEC created and supports the Bureau of Invasive Species and Ecosystem Health (BISEH). This group works across the state by providing expertise, assistance and action where invasive species are a threat. BISEH collaborates with numerous stakeholders including State and Federal agencies, non-governmental organizations, industry and notably through Partnerships for Regional Invasive Species Management (PRISMs).

A Framework for Response

The Rapid Response for Invasive Species: Framework for Response (PDF) was created to aid resource managers responsible for responding to newly discovered invasive species infestations. The policy outlines all the necessary components of an effective response, including: coordination; communication; public outreach; planning; scientific analysis; information management; compliance with laws and regulations; resources and logistics. DEC's experiences with managing invasive species such as northern snakeheads, hydrilla, oak wilt and emerald ash borer, were used to help develop and refine this framework.

Invasive Species Rapid Response and Control Grant Program

The Invasive Species Rapid Response and Control Grant Program shows DEC's commitment to implementing the agency's program policy entitled Rapid Response for Invasive Species: Framework for Response. The goal of this policy is to promote timely decision-making and communication in the event of a new invasive species infestation. This policy ensures that managers give adequate attention to all of the necessary components of an effective response including: coordination, communication, public outreach, planning, scientific analysis, information management, and compliance with legal and regulatory requirements, resources, and logistics.

In 2017, DEC awarded approximately $1.7 million dollars to 35 municipalities, not-for-profit organizations, and academic institutions. Visit the grants page for a full project list.

FINAL Invasive Species Comprehensive Management Plan

DEC and the NYS Department of Agriculture and Markets (DAM), co-chairs of the Invasive Species Council, are pleased to announce the adoption of the Final Invasive Species Comprehensive Management Plan (PDF) on Tuesday December 11, 2018. The overarching goal of the plan is to minimize the introduction, establishment and spread of invasive species throughout the State. Public comments on the draft Plan were accepted from April 18 through close of business on June 1, 2018. To view a complete list of individual comments and outcomes on the ISCMP, please see the Responsiveness Summary (PDF).
