Courthouse News reports that the US Fish and Wildlife Service has completed a 12 month review of a petition from Center for Biological Diversity to list the Ashy-storm petrel as endangered, finding that such a listing is not warranted at this time.

In denying the Center's petition, Fish and Wildlife found that there was insufficient scientific evidence that ocean acidification has had a negative impact on the krill on which the petrel feeds. The agency also determined that previous actions to prevent light pollution at petrel nesting sites, such as a limit on allowable wattage, and prohibitions on night fishing near large nesting sites, are sufficient countermeasures to protect the nocturnal hunting of the petrel.
