Several mechanisms have been used to acquire land for tropical-forest reservations. Legislative designation of National Parks on government-owned land, condemnation of private land, debt swaps, and outright purchase of private lands for reserves may, however, be inappropriate strategies in areas occupied by extant indigenous populations. In areas where indigenous peoples have a strong conservation ethic, the creation of reserves under partial or complete aboriginal control represents a viable alternative to the more traditional forms of land acquisition. Recently, three significant rain-forest reserves were created in Samoa using alternative strategies. 1) A US National Park in American Samoa involves the long-term lease of customary lands with local chiefs forming an advisory board on park policy; 2) in the Falealupo peninsula in Western Samoa, a covenant was established between the villagers who pledged to preserve and manage a large rain forest and private donors who provided funds for the construction of an elementary school; 3) in Tafua, Western Samoa, a covenant was established between the village, which vowed to preserve and manage the forest, and the Swedish Society for Nature Conservation (SNF) which provided funds for an elementary school and public works. These reserves suggest that under indigenous control robust solutions to the problems of rain-forest preservation can be achieved.

The freshwater ichthyofauna of the Fiji islands remained poorly documented before the establishment of the Pacific-Asia Biodiversity Transect (PABITRA) network. The PABITRA approach assesses biodiversity along ocean-to-mountain transects and promotes sustainable land use on islands across the Pacific. Multiple surveys of freshwater fish species along the Viti Levu PABITRA transect have contributed six new occurrence records and one new species to the known freshwater fishes of Fiji since 2002. In total, 21 indigenous species of fish (9% endemic) from 10 families and no introduced fishes were found in the three PABITRA sites. Diversity was highest (16 species) at Savura forest reserve and decreased further inland into Sovi and Wabu. The assemblage found is dominated by highly migratory species (95%) that traverse the different aquatic habitats (marine, estuarine, lowland and upland streams) covered by the PABITRA transect. This high degree of connectivity highlights several growing issues affecting aquatic fauna on the high island of Viti Levu. The reduction in forest cover along the gateway transects, especially in the terminal reaches, and infrastructure development such as dams and weirs have deleterious effects on the migration routes of the Fijian ichthyofauna. Several species collected are important food sources and have cultural totemic importance to local inhabitants along the vertical transect. This paper documents the ichthyofauna of the Fiji gateway transect, ecological characteristics of this assemblage, IUCN Redlist conservation assessment status and highlights factors affecting the fragility and resilience of these communities, particularly focusing on the importance of life-history patterns and watershed conditions.
