The rose-ringed parakeet (RRP), Psittacula krameri, has become established in at least four Pacific Island countries (Hong Kong China, Japan, New Zealand, U.S.A.), including the Hawaiian islands of Kaua‘i, O‘ahu, and Hawai‘i. Most Pacific islands are at risk of RRP colonization. This species was first introduced to Hong Kong in 1903 and Hawai‘i in the 1930s–1960s, established since 1969 in Japan, and in New Zealand since 2005 where it has repeatedly established after organized removals. The founding birds were imported cage-birds from the pet trade. In native India, RRP are generally found associated with human habitation and are considered a severe agricultural pest. In the Hawaiian Islands, RRP are increasing and expanding their geographic ranges below 500m elevation. Population estimates in 2018 on Kaua‘i were ?6,800 birds, which was a three-fold increase and a 22.5% annual growth rate in the prior 6 years, whereas O‘ahu had ?4,560 birds with a 21% annual growth rate the prior 9 years; these rates suggest a population doubling time of ?3.5 years. Wild RRP can live 14+ years, can reproduce after 1.5 years, and have few effective predators. Breeding pairs produce 1–3 fledglings annually. RRP are seed predators and rarely seed dispersers; their flock-foraging behavior can result in severe damage to orchard and field agricultural crops including tropical fruit and corn (Zea mays), and such economic damages are especially pronounced on Kaua‘i. Island societies should prevent new introductions and consider RRP deterrents and population control methods to protect resources.

This report provides an overview of the current state of knowledge of cetacean diversity, habitat and threats in the Pacifi c Islands Region. The boundaries of the Pacifi c Islands Region (Chapter 1), as defi ned by the Convention of Migratory Species (CMS) Memorandum of Understanding (MoU) for the Conservation of Cetaceans and their Habitats in the Pacifi c Islands Region (CMS 2006), are the marine areas under the jurisdiction of each Country or Territory of the Pacifi c Islands Region, and extend to the area defi ned by the Noumea Convention, i.e., between the Tropic of Cancer and 60° South latitude, and between 130° East longitude and 120° West longitude. The region stretches over some 10,000 kilometres from east to west and 5,000 kilometres from north to south, with a combined economic exclusion zone (EEZ) of approximately 30 million km². This region contains 22 Pacifi c Island Countries and Territories, as well as a portion of the Australian continent, both the North and South Islands of New Zealand, and a portion of the Hawaiian Islands. The region is purported to hold the most extensive and biologically diverse reefs in the world, the deepest ocean trenches, the world’s largest tuna fi shery, as well as a range of globally threatened species such as sea turtles, dugongs and cetaceans (UNDP 1999)
