Conservation of kakerori (Pomarea dimidiata) in the Cook Islands in 2003/04

Available Online

Saul, Edward K

In 1989, the kakerori (Pomarea dimidiata) was one of the 10 rarest bird species in the world, with a declining population of just 29 birds. During each breeding season since then, rats have been poisoned within the 155 ha of forested hill country they occupy in the Takitumu Conservation Area in southeastern Rarotonga. As a result, the kakerori population has rebounded, with a minimum of 292 birds found on Rarotonga in August 2003. In 2001/02, the emphasis of management shifted from the .recovery. of kakerori to a programme aimed at .sustaining. the population at 250.300 individuals. The major changes were an experimental reduction in rat poisoning effort to a level where recruitment of kakerori balances annual mortality, and a series of transfers to establish an insurance population on the island of Atiu. In 2003/04, all bait stations were filled fortnightly, rather than the previous mix of weekly and fortnightly refills. This reduced labour costs by 30% to 32 person days, and used a total of 39 kg of Talon® (active ingredient brodifacoum), which was only 13% of the maximum annual poison use over the same area during the .recovery. phase of the programme. Breeding success was high (0.91 fledglings/ breeding territory), even in the unpoisoned areas, and a record total of 80 fledglings was detected. The fortnightly poisoning regime offers promise as an effective, cheaper and less toxin-intensive method than that used previously, and so we recommend maintaining this regime in 2004/05, so that the longerterm effects can be assessed. A third and final batch of 10 young kakerori was transferred to Atiu Island in August 2003. This .insurance. population is becoming well established; the five breeding pairs monitored in 2003/04 each raised two fledglings, and a minimum of 15 birds was found in May.June 2004 in the small part of the island that was searched.

Secretariat of the Pacific Regional Environment Programme (SPREP)

SPREP's direction in the Islands Ecosystems Programme reflects a fundamental commitment to sustaining the livelihoods of island peoples today and tomorrow by supporting ecosystem management and species conservation. The Programme focuses on developing the capacities of the peoples of the Pacific islands to equip them to sustainable manage and conserve the terrestrial, coastal and marine ecosystems of their islands. The programme also focuses efforts to protect priority threatened species, and to protect Pacific island countries and terrttories (PICTs) from invasive alien species and living modified organisms (LMOs). In summary, SPREP's core business under this programme is to address the issues of ecosystem conservation, the sustainable management of natural resources and the protection of priority threatened species from the threats of human-induced impacts, invasive species and living modified organisms. These issues require action at the community, national,regional and international levels.

An assessment of Cyclone Heta's impact on Niue's coastline.

On 5th January 2004, Heta, a Category 5 tropical cyclone, struck Niue and widely devastated its N to NW exposed coastlines from Uluvehi to Alofi.

Update on the environmental and economic costs associated with alien-invasive species in the United States

Morrison, Doug

Pimentel, David

Zuniga, Rodolfo

Invading alien species in the United States cause major environmental damages and losses adding up to almost $120 billion per year. There are approximately 50,000 foreign species and the number is increasing. About 42% of the species on the Threatened or Endangered species lists are at risk primarily because of alien-invasive species.

Report to the Republic of Kiribati on Invasive Plant Species on the islands of Tarawa, Abemama, Butaritari and Maiana

Available Online

Imada, Clyde T

Space, James C

The Republic of Kiribati requested assistance from the US Department of Agriculture, Forest Service, Institute of Pacific Islands Forestry, to conduct a survey of invasive plant species of environmental concern. Similar surveys have been conducted in American Samoa, the Commonwealth of the Northern Mariana Islands, the Cook Islands, the Federated States of Micronesia, Niue, Palau, Samoa and Tonga. The survey was carried out in August and September 2003. We were requested to survey the islands of Tarawa, Abemama, Bern and Butaritari; however, difficulties with plane connections did not permit us to visit Bern and Maiana was substituted instead.

Report to the Government of Niue and the United Nations Development Programme: Invasive Plant species on Niue following Cyclone Heta

Available Online

Space, James C. et al.

On January 6, 2004, the full force of Cyclone Heta, a category 5 cyclone, hit the island of Niue. In addition to the loss of life and property, serious damage was done to the forests and other ecosystems of the island, particularly on the north and west sides. If not blown over, most trees and other large vegetation were stripped of leaves and branches and subjected to salt spray. This sort of disturbance provides an opportunity for new invasive species to become established and for many species already present to flourish. Following the cyclone, personnel from the Cook Islands, Fiji, French Polynesia, New Zealand and other countries visited the island to provide aid and assistance, and equipment and material were brought in to aid m the recovery. Although quarantine procedures were maintained there is always the possibility of inadvertently introducing new plant species during an emergency such as this. During the cleanup process nibble was moved and dumped in new areas, transferring invasive species to new locations.

Merremia peltata, disturbance ecology, tropical cyclones and Samoa. The biology and ecology of Merremia peltata are not well understood. While some regard the species as an exotic invader of Pacific Island ecosystems (Meyer. 2000). others identify the plant as a native species likely to be harmful to native ecosystems (Whistler, 1995a. 2002) or as either native or ancient Polynesian introduction behaving invasively (Space and Flynn.(2002). In Samoa, this species occurs up to an elevation of around 300 meters (Whistler 1995a). and thus only affects lowland ecosystems. This species increases its distribution and abundance in two ways, either vegetatively. by sprawling into neighboring areas and rooting from its nodes or by seeds, although early research in the Solomons observed a low seed viability rate, and creeping may thus be its primary means of reproduction (Bacon. 1982). M. peltata has apparently been in the Pacific for hundreds of years (Whistler, pers. com.) but has only become invasive in the years following tropical cyclones Ofa (1990) and Val (1991) according to comments from local government officials. Disturbance thus appears to be an ecological contributing factor to this invasion.
