It is worth noting that apart from the mainland, there are coastal ecosystems with their own characteristics and species well adapted to the environmental conditions that biome. In geography, it is customary to divide Brazil into regions that serve to delimit the geographic facilitating their administrative policies. Many are the proposals for division and are based on characteristics such as vegetation, climate and topography. In 1969, IBGE made the proposal, still used, to regionalize the country adopting criteria based on natural elements, social and economic macro resulting in five regions: North, Northeast, Midwest, Southeast and South However, the division into three regional complex is most often used because it is based on nature, economy and population, being more comprehensive and not obeying administrative boundaries. The three regional complexes are: Northeast, South Central and Amazon.

Važno je napomenuti da osim na kopnu, tu su i obalni ekosustavi s vlastitim karakteristikama i vrsta dobro prilagođena ekološkim uvjetima koji Biome. U zemljopisu, uobičajeno je da se podijele u Brazilu regijama koje služe se ograničavaju zemljopisno olakšavanje njihove administrativnu proceduru. Mnogi su prijedlozi za podjelu, a temelji se na karakteristikama kao što su vegetacije, klime i topografije. Godine 1969, IBGE napravio prijedlog, još uvijek se koristi, kako bi regionalize zemlju usvojiti kriterije na temelju prirodnih elemenata, društvenih i ekonomskih makro rezultiralo u pet regija: Sjeverna, sjeveroistok, zapad, jugoistok i jug Međutim, podjela na tri regionalne kompleksu se najčešće koristi jer se na temelju prirode, gospodarstva i stanovništva, što obuhvatniji i ne pokoravaju administrativne granice. Tri regionalne kompleksi: Sjeveroistok, Amazon i South Central.
