Japan and the Republic of Korea. The seeds of the invasive plant represent an entrapment risk, particularly for adults. There has been a decrease in the population of Swinhoe's Strom-petrels in Japan. Colonies have been adversely affected by mining activities and anthropogenic disturbance. The breeding population on Verkhovsky Island, Russia is likely threatened by recreational users in summer months.

  Recommended Management Actions
             Gain an improved understanding of at sea distribution in north west Australia

         Exchange information on successful Rattus spp. eradiation techniques with Korean and Japanese authorities
         Facilitate the collaboration between Australian, Korean and Japanese researchers to survey and monitor known colonies, study ecological requirements, search for undocumented breeding colonies in suitable habitat

 Wilson's Storm-petrel (Oceanites oceanicus)

 Life History and Distribution
Wilson's Storm-petrel (Oceanites oceanicus) is a small blackish storm-petrel with proportionately short rounded wings, square tail and long thin legs. In flight, feet usually project well beyond the tail. This species has an extremely large range, but most often seen over continental shelf waters. The breeding range of Wilson's Storm-petrels includes subantarctic islands from Cape Horn (Chile) east to the Kerguelen Islands (French Southern Territories), Macquarie Island, Heard Island and coastal Antarctica. The species undergoes a trans-equatorial migration, spending the nonbreeding season in the north Atlantic and north Indian Oceans. A number of individuals also migrate into the North Pacific Ocean. The species breeds in rocky crevices, on cliffs and amongst boulder scree. It feeds in cold waters with a diet comprised of planktonic crustaceans (especially krill) and fish.

 Population Estimates and Trends
Brooke (2004) estimated the global breeding population to number 4–10 million breeding pairs. The Australian population is poorly known owing to their small size and their cryptic nature on land. A couple of pairs of Wilson's Storm-petrel were detected in 1993 at Bishop and Clerk Island (Brothers and Ledingham 2008) and are also likely to be breeding on Macquarie Island (Tasmanian Parks and Wildlife Service unpublished data). In the absence of reliable population data, their current population trend is unknown.

 Conservation Concerns and Actions
The species is vulnerable from invasive species. On the Kerguelen and Crozet Islands, rats are reported to take chicks and eggs, causing nest failure. Cats may take adults in addition to chicks. Storm-petrels are known to be vulnerable to oil pollution at sea and marine debris.

 Recommended Management Actions
          Gain an improved understanding of at sea distribution in Australia

Grey-backed Storm-petrel (Garrodia nereis)

 Life History and Distribution
The Grey-backed Storm-petrel (Garrodia nereis) is the smallest storm-petrel in the Southern Ocean. At sea, the species appears as a tiny, fast flying storm-petrel with a small and slender body and
