Florianópolis has a native Atlantic Forest-type vegetation. This vegetation has an extremely diverse and unique mix of vegetation and forest types. The main ecoregion is the coastal Atlantic forest, the narrow strip of about 50–100 kilometers (31–62 miles) along the coast which covers about 20 percent of the region. This forest extends as far as 500–600 kilometers (310–372 miles) inland and its range is as high as 2,000 meters above sea level. Altitude determines at least three vegetation types in the Atlantic Forest: the lowland forest of the coastal plain, montane forests, and the high-altitude grassland or "campo rupestre".
