Central Avalonian Ecological Institute

The Central Avalonian Ecological Institute is an environmental agency founded by Baileneu Ma and Arbenz in 2004, with Theyka and Iere joining shortly after. The CA Ecological Institute has a variety of functions, such as ecoregion/biome classification and mapping, identifying and conserving threatened/endangered species, conservation area management, as well as pollution management. It has direct oversight in Baileneu Ma and Arbenz, whereas it acts as an advisory board in Iere and Theyka, it is authorised to use military grade equipment in Baileneu Ma and Arbenz for anti-poaching purposes, often acting alongside local militias and Communnal Defense Forces.

Wetlands
CAEI has a wide group of classifications for wetland ecosystems, due to their widespread presence in Baileneu Ma, with the qualifier for a wetland biome being an area that is either permanently or seasonally flooded. The ECI term for a wetland biome is 'W', with a variety of descriptors being used to further classify the wetlands into a specific ecoregion.

Forests
CAEI uses a similar classification system for forest biomes, using smaller descriptors to denote the various characteristics of forest ecosystems.
