Figure 1.
Frequency distributions of Area of Occupancy (A) and Extent of Occurrence (B) for New Caledonian Narrow Endemic Species.
Comparing NES with IUCN status of CR, EN, VU, or are recorded from 1, 2 or 3 locations.
Figure 2.
Map of “Hotspots of Plant Narrow Endemism” and protected areas in New Caledonia.
Values given per cell are the total number of NES summing NES 1, 2 & 3. Red ellipses indicate collections of cells that fall within named geographical locations such as mountains or valleys. The total number of NES in the red ellipses is indicated in brackets beside the name of site, numbers in red refer to the total number of NES 1. The line in the middle of Grande Terre (the main island) is the separation between the north and the south provinces.
Table 1.
Hotspots of narrow endemism (HPNE) in the New Caledonia flora where >7 NES are found per 2×2 km cell (see also Fig. 2).
Figure 3.
Groups of NES according to environmental variables.
(pptann : total rainfall per year, tmean: mean temperatures, alt: altitude). Each point is a unique NES. Symbols represent the geological substrate of the NES (o: volcano-sedimentary, Δ: ultramafic, +: anthropic formations and riverbanks, x: limestone). Points are coloured according to taxonomic families.
Figure 4.
Predicted distributions of the three groups of NES.
For each group, the map of potential distribution (colour according to probability of the habitat being suitable), and the name of location presenting the highest probabilities for a suitable habitat are detailed (Areas already identified as HPNE are in bold).
