The so - called Campos de Altitude (Altitude Fields) is an
ecosystem
of the
Atlantic
Rainforest
biome
that occurs in the higher elevations (> 1.500 m) of the
tropical and
seasonal
rainforest ecosystems.
The predominant elements are herbaceous and brushy
species such as poaceae, syperaceae, asteraceae and mimosaceae. The lower brushy species
frequently occur in the middle of a dense gramminoid carpet. The disjoined character and the geographical isolation
of this ecosystem are relevant factors for the occurrence
of
biodiversity
and endemism.
