About the Ecosystem

Wetlands are similar to swamps, but generally smaller, although there is no strict rule for telling them apart. They are environments where water is the fundamental component, forming a permanent or semi-permanent layer. They occupy the lowest positions in the landscape, in areas of flat topography. The plant and animal species found there are specially adapted to these conditions. They provide important ecosystem services: runoff regulation, filtering of surface waters and biodiversity conservation. This ecosystem also includes marshes and caraguatales, dense plant formations dominated by the caraguatá plant that develop in flood-prone areas.

BirdsThreatened

A small bird endemic to the region's wetlands and reed beds. The Curve-billed Reedhaunter is characterised by its reddish-brown plumage and its distinctive downward-curved bill, a unique adaptation for feeding among the reeds. It lives exclusively in tall grasslands and marshlands, where it searches for insects and small invertebrates. It is an indicator species for the health of wetlands.
