     notes: The Shannon index is a an index of crop diversity. Both the number of species and their distribution are 
       included in the calculation. Higher values indicate higher crop diversity. Typical values generally range between 1.5 and 3.5.

+      and taxonomic levels (mammals, birds, amphibians, reptiles, and plants). It
+      combines the original species count in the ecoregion and the reduction in natural
+      habitat, the threat level for each ecoregion and taxon, the taxon endemism, and
+      the species' preference for new artificial habitat induced by land use changes.
