  1. Comparison of the available biome maps for South America. The hierarchical division of each biome map is shown, followed by the number of headings under each division. The number of headings includes areas within South America only, although some schemes extend to Central and North America. Human made habitats (e.g. urban areas, agricultural land) and barren areas (e.g. water, ice, and snow) were excluded from the comparison where possible. Tiers above continental scale (e.g. realms) are not shown.
  2. 1 Total number of terrestrial biomes in WWF Ecoregion map is 14 but some of the major biomes not found within South America.
  3. 2 Shape layers for the individual ecological systems are not available yet for the whole of South America. The number of polygons given is the current estimate. The currently available map is divided into 604 polygons.
