Feral animals on Hawaiʻi Island
Mongoose and coqui frogs are established on Hawaiʻi Island, along with feral cats, pigs, goats and chickens. Axis deer are not: the deer brought over in 2009 were removed, so a deer sighting is a same-day call. The state also asks everyone to test for little fire ants.
What to report on Hawaiʻi Island
Every species below can be reported on the map. Where a species is not established here, a same-day call matters more than the map; those rows are marked.
