Abstract
Context
Wetland classifications aid decision-making for conservation purposes. Multiple classifications exist for the Murray–Darling Basin, Australia, including the Australian National Aquatic Ecosystem (ANAE) classification and ones for each Basin State. The Basin ANAE classification lacks clear definitions of wetland types and is misaligned with international conservation frameworks. Most State-based classifications cannot be used to support wetland management at Basin-scale.
Aims
Our objective was to provide a simple, consistent, standardised classification of wetlands for the Basin to support for decision-making on conservation policy and management.
Methods
We assessed the applicability and compatibility of existing classifications on the basis of principles of adequacy of definition, consistency, information quality and reproducibility. We merged datasets of vegetation communities from each Basin State into vegetation classes used by New South Wales, which aligned most closely with these principles. We mapped wetland extent within protected areas and areas that receive managed environmental flows.
Key results
We identified nine major wetland types. Only 8% of their extent was within protected areas and 12% within the actively managed floodplain.
Conclusions
Basin wetlands are poorly protected and continue to rely on occasional high, natural, unregulated flows for their persistence.
Implications
Our synthesis presents a consistent typology of wetlands that can be used to improve conservation policy and management.
