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 southeastern Rarotonga. As a result, the kakerori population has rebounded, with a minimum of 259 birds being found on Rarotonga in August 2002. In 2001 and 2002, 20 yearlings were transferred to Atiu in the first two of three planned annual transfers to establish an ‘insurance’ population. In January 2003, three pairs of kakerori were found on Atiu, and successful breeding was proven with the discovery of six island-bred (unbanded) birds, belonging to at least two of the pairs. In 2002/03, the emphasis of management in the Takitumu Conservation Area shifted from the ‘recovery’ of kakerori to a programme aimed at ‘sustaining’ the population at about 250 individuals. The key to this work was the experimental reduction of rat poisoning effort, so that 30 territories had the standard weekly refills of poison bait stations, 29 received a fortnightly refill, and 20 received no rat control. As expected, breeding success was significantly better in poisoned areas (with an average of 0.95 fledglings per breeding territory) than in unpoisoned areas (with an average of 0.30 fledglings per breeding territory). This reduced rat control programme took 2–3 person days each week for 15 weeks, and used a total of 43 kg of Talon® (active ingredient brodifacoum), which was about 20% of peak poison use during the ‘recovery’ phase of the programme. The fortnightly poisoning regime offers promise as an effective, cheaper and less toxin-intensive method than that used previously.

2002
In this, the sixth and final volume in this series, Jenny Whyte and her colleagues at the Foundation of the Peoples of the South Pacific International and affiliated organizations provide a review of information relating to lessons learned and best practices for resource and habitat conservation and sustainable management initiatives in the Pacific islands region. The review focuses on community-based (participatory) issues associated with the conservation and sustainable management of resources and habitats in island ecosystems with emphasis on the four focal areas for the International Waters Programme (sustainable coastal fisheries, marine protected areas, community-based waste reduction and preservation of freshwater resources). Issues are considered in context of the entire project cycle – from project planning and design; selection of sites; method of community entry; community baseline assessments; participation of communities; the role and participation of governments and, if they are involved, external agencies, NGOs and development assistance agencies; education and awareness activities, completion and exit considerations such as alternative income generation, and monitoring and evaluation. The review considers social, cultural, economic, environmental, administrative, managerial, legal and political dimensions of such projects.
