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.
Pontogammarus borceae is an amphipod native to the Pontic area and the Caspian basin. Information is limited for this species but there are some studies suggesting potential uses in aquaculture. P. borceae has not been reported anywhere outside its native range resulting in a history of invasiveness classified as No Known Nonnative Populations. The climate match for the contiguous United States was High. Locally, much of the contiguous United States had a medium match except for areas along the mid and northern Pacific Coast, the Gulf Coast, and northern Great Plains and New England, which had a low match; and the Intermountain West and the Southwest, which had a high match. A large portion of the species’ range was unable to be represented in the climate match due to a lack of georeferenced observations. Certainty of assessment is Low due to a lack of georeferenced locations and information regarding history of invasiveness. The overall risk assessment category for Pontogammarus borceae is Uncertain.
