Vegetation also is linked to the high variability caused by ENSO. The following are just some of the characteristics of Australian vegetation that may be, at least in part, attributable to the ENSO influence on the climate: absence of succulents, establishment dependent on extended wet periods, drought tolerance/avoidance, diverse life-history strategies, and fire resistance/dependence (Nicholls, 1991).

These are just a few examples of the many and varied adaptations of Australian biota to the highly variable rainfall found in some members of most groups of Australian plants and animals. There appears to be a consensus among ecologists that much of the Australian flora and fauna is adapted to a highly variable rainfall that, in tura, is caused by the ENSO, and that this adaptation is more complete than in other areas of the globe.
