The Pantanal is
one of the largest and most spectacular freshwater ecosystems in the
world, with an exceptionally high biodiversity. It is located south of
the Amazon basin, at the crossroads of Bolivia, Brazil,
and Paraguay. It covers an estimated area of 175,000 square kilometers,
about half the size of California. Numerous distinct ecological systems
exist within its confines.
Tributaries of the Paraguay River flood and recede every year,
rhythmically transforming the region from floodplains to grassy
savannahs. In addition to critical habitats for a diverse and highly
concentrated array of vegetation and wildlife, the Pantanal’s
hydrological system supports and provides certain invaluable ecosystem
services to local communities, such as water purification, nutrient
storage, sediment trapping, flood control, storm protection, and
climate stabilization.
Located in the center of South America, the Pantanal forms a link
between the biomes of the Amazon, the Cerrito savannah and the Chacos
of Bolivia and Paraguay. The region lies at an altitude of less than
150 meters and the landscape is virtually flat. During the rainy season
up to 80% of the territory is inundated, forcing out most of the local
population, who temporarily migrate to the surrounding towns and
villages. Beyond rivers and various forests, the Pantanal is a complex
system of marshlands, floodplains, lagoons and interconnected drainage
channels.

There is a fear that the Pantanal wetland may disappear by 2050.
According to Conservation International, deforestation in the Brazilian
Pantanal has quadrupled in recent years. Already,17 percent of the
original vegetation has been lost in the region.
The envisioned wilderness would encompass most of this marsh
land as well as some adjoining uplands. The proposed Pantanal
Wilderness is shown below in a satellite view of the earth. The location
of the Bolivian Altiplano and the cities of Santa Cruz, Cuiaba and
Campo Grande provide for orientation of the viewer. Wildlife corridors
would connect it to the Amazon jungle to the north, the Cerrado of
Brazil to the northeast, and the dryer Chacos to the south and west.
The Andes Mountains and the Altiplano would overlook the wilderness
region from the west.

The Pantanal Megafauna Chart below
lists prospective wildlife inhabitants, current and envisioned (such as
the Sitatunga Antelope from Africa on the left), that would most probably
thrive in the Pantanal wetland. Those with a darker gray background are
proposed new inhabitants not native or naturalized to South America.
Where endangered, the categories are indicated; (CR, EN, VU & LR)
or extinct in the wild (EW) according to the IUCN.
