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

DRAFT Invasive Species Comprehensive Management Plan

DEC and the NYS Department of Agriculture and Markets (DAM) are seeking comments on the draft Invasive Species Comprehensive Management Plan (PDF, 2.53 MB). The overarching goal of the plan is to minimize the introduction, establishment and spread of invasive species throughout the State. Public comments will be accepted on the draft plan from April 18 through close of business on June 1, 2018. Comments may be sent to isinfo@dec.ny.gov or via mail to NYS DEC, Invasive Species Coordination Section, 625 Broadway, Floor 5, Albany, NY 12233-4253.

For an overview on the Draft Invasive Species Comprehensive Management Plan, please view the presentation (PDF, 2.96 MB).

Managing Invasive Species

A Framework for Response

The Rapid Response for Invasive Species: Framework for Response (PDF, 1.3 MB) 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.
