The Long Island Invasive Species Management Area

About Us

Who We Are:

We are a voluntary partnership of many organizations from the geographic area that includes Staten Island (Richmond County), Long Island (Kings [Brooklyn], Queens, Nassau and Suffolk counties), and eleven additional coastal plain islands. We are one of eight PRISMs (Partnership for Regional Invasive Species Management) that cover all of New York State.

Our Mission

We believe we can help conserve LIISMA's biodiversity, wildlife habitat, recreation resources, scenic quality, and crop production, while protecting human health and safety, by facilitating cooperation and coordination among land owners and managers to reduce the threat of human-introduced invasive species. We also believe we can reduce the costs of invasive species management by preventing and eradicating new invasive species infestations before they become established.

How We Do It:

LIISMA brings together representatives from many government agencies, non-profits, and private businesses to discuss, share and learn from each other the latest invasives strategies and issues.


  • Build partnerships and facilitate coordination among stakeholders.
  • Prevent new invasive species introductions.
  • Gather new information about invasive species through field work and research.
  • Train agency staff and volunteers in identification, prevention, mapping, monitoring, and management protocols.
  • Rapidly detect and respond to new invaders.
  • Help manage established invasive species to protect and restore target resources.
  • Monitor changes and evaluate results of management efforts.
  • Elevate the profile of the invasive species issue through education and outreach with an emphasis on prevention measures and Best Management Practices.
  • Establish new funding, policy, and management support at the State, County and Town levels.

Funding for LIISMA is provided by the New York State Environmental Protection Fund as administered by the New York State Department of Environmental Conservation.

Anyone interested in invasive species may become a partner of LIISMA. Formerly coordinated by The Nature Conservancy's Long Island Chapter, LIISMA coordination was transferred to the Long Island Native Plant Initiative (LINPI) in July of 2016.
