Advances in water management of southern Brazilian sub-tropical wetlands using bio-indicators

摘要

This study presents a new criterion for water management in southern Brazilian sub-tropical wetlands through the use of biological indicators. The emergent aquatic macrophyte giant grass Zizaniopsis bonariensis, was used to define a suitability index. Hydrological scenarios were combined with the suitability index, allowing the selection of good habitat water levels. The results showed the importance of biological indicators' inclusion in the criteria list for water management Under some conditions predicted by traditional hydrological procedures this emergent macrophyte species would be stressed.
