The ANS Hotline has been discontinued and replaced with an online reporting tool of the USGS Nonindigenous Aquatic Species Database and its associated Alert System.
Do you want to report an aquatic invasive plant or animal? Do so here: USGS NAS Database Online Sighting Report Form.
Do you want to receive alerts of new sightings of specific aquatic invasive species, or receive alerts for a taxonomic group or for one or more states? Do so here: USGS NAS Alert System.
