Restoration of Nu'utele & Nu'ulua, Aleipata islands, Samoa protection of friendly ground dove during proposed rat eradication / D.J. Butler

Available Online

Butler, D.J.

For one of the species potentially at some risk of poisoning under the proposed rat eradication regime, the Friendly Ground Dove, Nuutele and Nuulua hold populations that are nationally significant. The complete loss of these populations would threaten the survival of the taxon in Samoa. Some authors consider the Samoan doves to be a separate race (Gallicolumba s. stairi) from those in Fiji and Tonga (Watling, 2001). Outside Samoa, the race is only found on the small island of Ofu, American Samoa where it is threatened. So the loss of Nuutele and Nu'ulua birds could threaten the race with extinction.

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.

Preliminary Analysis of Vector Routes and Selected Invasive Species for Pacific Island Countries and Territories

Available Online

Green, Wren

Understanding vector routes for invasive species (i.e. the routes by which pest plants and animals move from place to place via human assistance) is a key element in global and national efforts to reduce risks and limit the further spread of invasive species. This report is divided into two main sections. The first section provides a quantitative analysis of air and sea movements between the countries and territories of the Pacific. The second section summarises information on eighty existing or potential invasive plants and animals to Pacific islands. While the GEF project with which this report is linked is limited to SPREP countries, the analysis also includes the territories of the region (with the exception of Pitcairn Island). This is essential since some territories are pivotal to understanding vector routes and transport hubs in the region. For the same reason, flights from Pacific islands to Hawaii are included, as well as including Hawaii in the analysis of the selected invasive species. There is significant variability in the volume and patterns of ship movements and aircraft flights between the countries and territories of the Pacific, which is consistent with their diverse sizes, economies, exports, and political linkages. A few countries emerged as significant hubs for sea and air transport within the region. (Refer to Tables 1 and 2 for summaries.) In the northern Pacific, Guam emerges as the high risk country, given its high levels of total merchant ship and oceanic fishing vessels as well as the largest number of weekly flights to other Pacific island countries (139) and to Asian destinations (148). In the central southern Pacific, Fiji is the major transport centre with a large volume of merchant shipping, cruise liners and itinerant yachts (585 yearly visits) and relatively high numbers of weekly flights both within and outside the region. To the east, French Polynesia has a smaller annual number of merchant ship visits, but when other shipping activity is included, as well as 26 weekly flights to the USA (including Hawaii) and more within the region, it emerges as an important vector route. (It already has a significant number of invasive species). Papua New Guinea and New Caledonia are important countries in the western Pacific for shipping volumes; New Caledonia also for visits by yachts (500/yr). Papua New Guinea has extensive air links with Australia, another source of tropical invasives, but very few within the Pacific. New Caledonia has a larger number of weekly flights than Papua New Guinea spread within the region, as well as to Asian, Australian and New Zealand destinations. The information in the second section on eighty invasive species provides evidence for the links between trade, travel and the distribution of invasives. Vector routes and methods of spread are identified. It also highlights the importance of early detection and eradication if Pacific countries are to be more effective at limiting the arrival and spread of invasive species.

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

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.
