Orinoco Delta is one of the eight natural regions of
It is covers the whole of
Delta Amacuro State and a few square
Monagas State and Sucre State , comprising all the
mouths of the
Orinoco . It is divided into two sections: the
principal, at the northernmost part of the system, located between
Caño Manamo and the left shore of Caño Araguao , where the majority
of villages are established, including the state capital,
and the secondary, between the right shore of Caño Araguao and Río
Warao people live in the region.
The delta is fan-shaped, formed by the
Orinoco River as it splits
into numerous distributaries , called caños, which meander through
the delta on their way to the sea. The main distributary is called the
Rio Grande, which empties south-southeast through the southern portion
of the delta, and the second major distributary is
Caño Manamo ,
which runs northward along the western edge of the delta. The area of
this region it's approximately 43,646 square kilometres (16,852 sq
Orinoco Delta is characterized by being non-centric, lagoon
lacking, and oceanic , somewhat similar to the delta of the Niger
River . Daily tides bring sea water up the "caños", causing the
"macareo" or pororoca and revsering the flow direction of water, at
least on surface.
The predominant vegetation is in the
Orinoco Delta swamp forests
ecoregion. Along the coast and the river margins there are stretches
Amazon-Orinoco-Southern Caribbean mangroves , specifically the
Guianan mangroves ecoregion. To the west, and closer to the coast,
there are patches of the
Orinoco wetlands ecoregion.
The delta includes large areas of permanent wetlands as well as
seasonally-flooded freshwater swamp forests . The river margins of the
delta are fringed with mangroves .
