Terrestrial ecoregion

The terrestrial ecoregions are, in ecology, those ecoregions of land and fresh water, as distinct from those in the oceans.

This conflicts slightly with traditional usage of terrestrial as a synonym for "terran" ("of Earth" in general, whether land or oceans). It follows its alternate meaning, roughly "of dirt", e.g. as in Terrestrial planets, which are, obviously, not all Planet Earth, i.e. Terra, but only of similar mineral composition.

There are 867 terrestrial ecoregions organized into 8 major ecozones.
