Table 2.
The overlap of our biodiversity priority areas with high value areas for different taxonomic groups from the CNA study. In the case of vertebrates, the comparison is with that of four different expert maps. The current best set of priority areas contains areas both to the north (Toricelli Range) and south (Sepik floodplain) of the CNA priority 1 area in the western Sepik district. These areas may overlap with the priorities of some of these experts, but the summarised map of CNA areas is drawn at too broad a scale for an accurate determination.

Table 4.
Descriptions of existing protected areas and five alternative sets of areas (different columns), for key factors (rows) relating to costs, constraints and preferences. nc = not calculated. The baseline set is the set covering 10% of PNG that was used to help set the biodiversity target. Implied costs and constraint values are shown for the baseline set, but were not used to derive that set. "All costs/constraints" corresponds to the current best set of biodiversity priority areas. In the last three columns, the analysis in each case uses all factors but with the listed modification. "LUI < .5" means the number of selected areas that have less than 50% of their area falling in the PNGRIS highest land use intensity class.
