List of ecoregions in Indiana
The list of ecoregions in Indiana are listings of terrestrial ecoregions (see also, ecosystem) in the United States' State of Indiana, as defined separately by the United States Environmental Protection Agency (USEPA), and the World Wildlife Fund.
USEPA
The USEPA ecoregion classification system has four levels, but only Levels I, III, and IV are shown on this list. Level I divides North America into 15 broad ecoregions (or biomes). Indiana is within the Eastern Temperate Forest environment, Level I region. Level IV ecoregions (denoted by numbers and letters) are a further subdivision of Level III ecoregions (denoted by numbers alone).[1][2][3]
