The Pacific-Asia Biodiversity Transect Network

A new strategy: Combining the horizontal and vertical approaches to ecosystem studies and conservation

PABITRA is a collaborative program for investigating the function of biodiversity and the health of ecosystems in the tropical Pacific Islands. Particular emphasis is put on the comparative analysis of indigenous upland and inland forests of the volcanic high islands and their role as ecological reserves and watersheds. Their function under the natural biogeographic restraints of isolation and their watershed services in relation to the various lowland ecosystems will become the principal focus of collaborative research.
