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.

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.
