The region covered by the Geopark Project is fully inserted in the Atlantic Forest Biome, considered the richest in biodiversity in the entire planet (some also consider a small occurrence of the Pampa Biome in Torres - RS).
Currently, less than 10% of the original area of the Atlantic Forest remains, and yet its floristic and faunal biodiversity is exceptional, and much of this is due to the fact that the region has a gradient of altitude, humid climate and a great diversity of natural environments such as: beaches; sandbanks; dune fields; wetlands in general; ponds; rivers, and various types of forests.
A variety of forest biomes stand out, such as:
Regarding fauna, the geopark project area basically covers the Atlantic Forest Zoogeographic Region, and as with the flora, the fauna is quite diverse, according to the different existing environments, and in addition there are a significant number of endemic species (ie exist only in a certain natural environment), which is one of the facts that justify the existence of Conservation Units, such as the Aparados da Serra and Serra Geral National Parks in Cambará, Jacinto Machado and Praia Grande; Itapeva State Park and Itapeva Lagoon APA both in Torres; and Silveirão APA in Mampituba.
Among the various species of animals occurring in the geographical region of the Geopark we can highlight:
