About ISAC

The National Invasive Species Council’s (NISC) high-level policy and planning activities benefit from the technical input provided by Federal agency staff,  and Federal inter-agency bodies working on invasive species issues, as well as non-Federal stakeholders. The Invasive Species Advisory Committee's (ISAC) primary duty is to “provide information and advice for consideration by the Council” on invasive-species related issues. ISAC members include representatives of state, territorial, tribal, and local governments, as well as academic institutions, non-governmental organizations, and the private sector. 

ISAC is chartered under the Federal Advisory Committee Act (FACA) and administered according to its bylaws. ISAC typically holds two meetings per year. All meetings are open to the public, and minutes of each meeting are publicly available. 

Since its creation in 1999, ISAC has provided valuable input to NISC on a wide range of Federal priorities and emerging issues. ISAC advice and other resources are available. ISAC was deactivated in May 2019, and reauthorized in October 2021. ISAC members are appointed by the Secretary of the Interior with extensive input from the other NISC members.

The current ISAC members were appointed on December 26, 2024.  Total membership includes 13 voting members appointed by Secretary Haaland, and five non-voting, advisory members representing stakeholder non-governmental organizations (NGOs).
