Papua New Guinea Biodiversity Surveys: The DIWPA/PABITRA Intersection

Since 1994 we have established a set of one-hectare plots in less disturbed rainforests along a north-south axis from south-east Queensland to northern Borneo. From south to north our sites are at Lamington National Park, the Conondale Ranges, Eungella National Park, Paluma, the Atherton Tablelands and Brunei. Beginning in June 1999 we are adding the first of three plots in Papua New Guinea to this sequence. This first plot is located at Baitabag near Madang. A second site will be established in 2000 at Finschaven on the Huon Peninsula with a final site planned for the island of New Britain in 2001.

Surveys at these sites (each of which has two satellite quarter hectare sites) include a complete inventory of trees >5cm dbh and an arthropod survey including seven different and complimentary sampling techniques. Sample results will be presented. The techniques used for arthropod survey are in large part those adopted by DIWPA for its projected 'Asian green belt' survey. The sites represent semi-permanent reference plots for ‘anchoring’ other comparative studies, they allow assessment of pattern on a large scale across a key biogeographic boundary, they generate important taxonomic collections, and they represent a ‘control’ for assessing biodiversity in degraded forests.

The New Guinea sites, in progress, represent the intersection between the Australia/Asia north-south transect and the west-east PABITRA transect. The opportunity for adding arthropod dimensions to the PABITRA activities and ensuring compatibility for vegetation measures will be discussed.
