Long Island Invasive Species Management Area
The Long Island Invasive Species Management Area (LIISMA) aims to conserve 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; and to reduce the costs of invasive species management by preventing and eradicating new invasive species infestations before they become established.
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.
