A Biodiversity Conservation Plan for Papua New Guinea Based on Biodiversity Trade-offs Analysis

Figure legends

Figure 1.
Maps showing costs, preferences and masks information for TARGET analyses.

a) Coded timber volume ratings for RMUs. Yellow is highest class, followed by orange.

b) RMUs (orange) having agricultural potential according to a simple index.

c) Overlap (green) of existing protected areas with RMUs.

d) RMUs (orange) with current high land use intensity.

e) Overlap (black) of RMUs with areas having highest priority in the Conservation Needs Assessment.

f) RMU overlap with human population density classes. Yellow is highest category, followed by orange and then purple.

Figure 2.
Diagnostic maps based on the current best set of priority areas, combined with information on costs, preferences and constraints. Green RMUs in each case are those in the proposed set overlapping with coloured areas in Figure 1 maps.

a) the current best set of priority areas

b) portion of proposed set that overlaps with high timber volume areas

c) portion of proposed set that overlaps with agricultural potential areas

d) portion of proposed set that overlaps with CNA priority one areas

Figure 3.
Black and red areas (RMUs) are those in which Queen Alexandra's Birdwing Butterfly, has been recorded and the red areas are those RMUs contained in the selected priority set (green designates all other priority areas).

Figure 4.
Each map shows the current best set of priority areas, with priority set areas assigned colours to indicate key values for decision-making factors. Green areas in each case are remaining priority areas.

a) relative complementarity values of the priority areas (yellow is highest category, followed by orange, then purple).

b) must-have areas (orange) in order to achieve the 10%-based target

c) all priority areas having more than half their area in the highest PNGRIS land use intensity class (orange)

d) priority areas having highest ratings for timber volume (yellow is highest category, followed by orange, then purple).

Figure 5.
An expanded map of northeast PNG to show areas having high timber volume per unit area, and their substitute areas.

a) 50 areas (white) are in the priority set, among all those areas (black and white) that have high timber volume per unit area.

b) six priority areas with very high timber volume per unit area (white) and the three areas (blue) that could replace these (while still reaching the target). Other areas having high timber volume per unit area are shown as brown.

Figure 6.
The yellow areas are those areas in a modified best set, building on the previous current best set, but only allowing must-haves and existing protected areas in New Britain to be retained. The additional areas shown as green then would be needed in order to reach the 10%-based target.
