The Pantanal

The Pantanal is one of the largest wetlands in the world,

presenting great diversity and complexity due to its ecological

relationships bounded to the flood regime. This regime is

maintained by the connectivity between the plain and the

plateau, where the main rivers that supply this biome rise.

Because of its natural resources, the Pantanal presents high

socioeconomic value. However, the current development model

in the region has been resulting in irreversible degradation,

threatening the functionality of this natural system and the

survival of traditional livelihoods. From the definition of the

essential factors for the maintenance of the ecological function of

the Pantanal and its main threats, it is possible to assess its

conservation status and risk of collapse.

The Red List of Ecosystems

The Red List of Ecosystems was developed by the

Commission on Ecosystem Management of IUCN (CEM) to

assess the conservation status of the natural systems in

different scales. The application of the criteria is essential for

evaluating the risk of collapse of the ecosystems and is

considered a powerful tool for long-term conservation planning.

Red List of Ecosystems

Since 2012, IUCN Brazil, PROVITA and the Commission on Ecosystem Management (CEM/ IUCN) started mobilizing institutions interested in applying the methodology to provide support for decision making processes related to the conservation of Brazilian biodiversity. A working group was formed, joining representatives of different sectors of society. This group is responsible for developing case studies in several regions of the country, including the Pantanal Wetlands as an important experience for promoting a national Red List of Ecosystems.

Methodology

Thirteen ecosystem units were defined for the assessment of

the Pantanal biome by crossing the vegetation maps of the

Project RADAMBRASIL (1982) and the flood regime data,

according to PADOVANI (2010). The criteria A and B were

applied to quantify the reduction in the geographic distribution

and evaluate the ecosystem loss.

Preliminary Results

With the application of criteria A and B, we came to the

conclusion that one ecosystem is Critically Endangered, three

are Endangered, three were considered Vulnerable and six

are Least Concern.
