There are less than 2500 Foveaux shags remaining. The population seems stable and retains much of its genetic diversity in comparison to the Otago shag, which is continuing to decline. Foveaux shags have fared better than Otago shags because they nest on inaccessible islands just offshore.

Nevertheless, their small population size make both species vulnerable to extinction, and conservation efforts will need to be tailored to each species' demographic history, genetic variation, and restricted geographic distribution.
