Join the Invasive Species Team

OCCA’s Invasive Species Team is a year-round volunteer program designed to be flexible and accessible. As a volunteer, you choose your level of involvement—whether that’s reporting an invasive species you notice in day-to-day life, removing invasives from places you care about, or opting into our seasonal challenges.

Getting started is simple: join OCCA’s group on iMapInvasives, New York State’s official invasive species database, and report the invasive species you see or remove locally. You’ll also receive periodic emails from OCCA with seasonal ID tips, learning resources, and different group opportunities to get involved.

However you choose to participate, your observations will help protect local habitats and guide local conservation work.
