Amazon Tours / Brazil – Vegetation and flora of the
Amazon Rainforest biome can be divided into
Campinarana,
dense and
open Tropical Rainforest,
Pioneer Formations, Savannah (
Cerrado),
Steppe - Savannah (
Caatinga) and secondary vegetation.
Campinarana
Campirana is a type of vegetation which is restricted to the upper Rio Negro, in the northern Amazon region.
It is subjected to an ombrophilous climate, characterized by sudden, strong rainfalls (about 4.000 mm / year) and high temperatures (average > 25°C).
Due to the lack of nutrients in the soil, it is characterized by a tall and thin vegetation that occurs in depressed, mostly swamped areas.
A tipical species of Campinarana is the
palmeirinha or
piaçabarana (
Barcella odora).
Dense Tropical Rainforest
The dense tropical or ombrophilous rainforest (
floresta ombrófila densa) is the predominant vegetation of the Amazon rainforest.
It occurs as
alluvial (see also:
ecosystems) and
lowland rainforest in the
Amazon Basin and as
submontane rainforest on the scarps and ondulated plains of the
Guianas and
Guaporé highlands (see also:
geology).
Open Tropical Rainforest
Simplified, the open tropical rainforest (
floresta ombrófila aberta) is a transitional vegetation between the Amazon and the Cerrado.
It is characterized by more spacious trees with a less dense canopy stratum.
It occurs in
tropical climate, with a long dry season of up to 4 month and average temperatures
of about 25°C – Brazil Travel / Tours.
