In September 2000, the Millennium Ecosystem Assessment (MA) issued a call for proposals to undertake ‘sub-global’ assessments at local, national, and regional scales. The Call for Proposals was circulated amongst a group of social scientists who had previously had some connection to PNG’s Biodiversity Conservation and Resource Management Program – an initiative which had been funded by the Global Environment Facility from 1993 to 1998. This program had sought to evaluate the actual and potential effectiveness of ‘integrated conservation and development projects’ in forested areas of PNG where high biodiversity values are associated with low population densities. One of the key lessons of the program had been that local communities in these areas are far more interested in ‘development’ than in ‘conservation’, because they can reasonably say that they have been conserving their ecosystems for thousands of years, but are now lagging in their access to modern health and education services because of their small and scattered populations (McCallum and Sekhran 1997; van Helden 1998, 2001; Filer 2004b). If the Government cannot afford to provide these services to remote and thinly populated areas, then local people tend to dream of the day when a logging company or mining company will deliver them from their state of backwardness.

Between 1892 and 1930, 58 percent (30 taxa) of Hawaiian endemic forest birds either were greatly reduced or became extinct. The order in which the islands experienced major declines ofseveral forest birds is Oahu (ca. 1873-1887), Hawaii (1892-1900), Mo10kai (1893-1907), Maui (18941901), Kauai (after 1900), and Lanai (1926-1932). Loss of habitat, reduced food supply, introduced avian diseases, as well as predation by man, feral cats, mongooses, and Norway rats (Rattus norvegicus) all appear to have reduced some species ofbirds, but none ofthese factors adequately explains the accelerated rates ofdecline offorest birds that occurred after 1892. Although it has been assumed that roofrats (Rattus rattus) reached Hawaii with the first European ships at the end of the 18th century, there is circumstantial evidence, independent of the bird decline data, that indicates that this rat did not arrive until after 1840, probably between 1870 and 1880. The hypothesis is advanced that after its establishment on Oahu in the 1870s, R. rattus spread to the remaining large islands in the group, resulting in a stepwise accelerated decline offorest birds on each island in turn. Hawaii thus parallels some other Pacific islands where major reductions of birds have followed the establishment of R. rattus. The need for precautions to prevent rats from reaching rat-free islands in the Hawaiian group is emphasized.
