Within each island 100×100 m geo-referenced plots were selected. Transects of 100m were established at each plot, consisting of 15 traps/sampling method (60 samples per transect). Plant landcover was recorded. Two replicates per habitat type and island were made (i.e., 2 replicates x 8 habitat types x 5 islands) for a total of 80 sampling sites, and 4 collecting methods. Species accumulation curves were calculated to determine if sampling reached a plateau, hence if sampling was representative of the overall diversity at a given locality. Overall diversity(α) and unique diversity (ß) was determined per trap, habitat and island.
