Nevertheless, Reunion Island has an angiosperm flora of approximately 500 indigenous species, 30 percent of which are endemic. Mauritius has approximately 870 indigenous species, about 35 percent of which are endemic. The only available explanation for these differences appears to be age of the flora. Mauritius is seven million years old, whereas Reunion is four million, so, until the decimating influence of human settlement intervened, the flora of Reunion was still diversifying relative to that of Mauritius (see chapter 2; also Fiedler  for discussion of the "age and area hypothesis").

Thus, although some reasonable temporal and spatial limits for categorizing taxa are suggested, it is assumed that factors such as generation time and ability to disperse will influence the categorization of any given taxon. It also is better to define temporal persistence in terms of generation time and spatial distribution in the context of gene flow, because these definitions allow a more meaningful comparison among taxa. However, rarely does sufficient data exist to allow such comparisons. Therefore, we suggest time in years and areas in hectares.
