Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.
Pomacea paludosa is the only species of applesnail native to the United States. Its native range in the U.S. is restricted to Florida, but it has become established in South Carolina and Alabama, with additional collections made in Hawaii and other southern states. P. paludosa has a medium climate match with the United States. Although the species has been documented as introduced outside of its native range, it is unclear what impact, if any, it is having on the ecosystems where it has been introduced. Overall risk assessment category for this species is uncertain.
