Wetland Prioritisation Decision Support System (DSS) Great Barrier Reef Catchment
Description and method logic
To strategically prioritise wetlands for investment. The DSS operates at two scales. The primary DSS prioritises wetland aggregations within the GBR catchments and uses GIS analysis methods to priroritise existing catchment scale datasets. The secondary DDS is used to prioritise individual wetlands using local expert knowledge and GIS analysis.
The decision support system (DSS) aims to use biophysical, socio-economic, community capacity, threat data and expert consultation to identify high priority wetlands for strategic investment and to achieve greater accountability and transparency in wetland prioritisation.
The development of the wetland DSS involved a number of steps including a review of international and national literature and decision support systems, data assessments, data processing and workshopping with nominated experts and stakeholders.
The DSS operates at two scales. The primary DSS prioritises wetland aggregations within the GBR catchments and uses GIS analysis methods to priroritise existing catchment scale datasets. The secondary DDS is used to prioritise individual wetlands using local expert knowledge and GIS analysis. Primary and secondary wetland DSS tools have been developed in separate MS Excel workbooks which provide the user with the capacity to view prioritisation results, assign priorities to criteria and, for the secondary DSS, input data for wetland criteria.
The Primary and Secondary DDSs were tested at a series of workshops with regional and local decision makers. The results were then interrogated and feedback received for the participants. The DSS and associated reports have been externally peer reviewed and a sensitivity analysis has been undertaken.
The DSS could be improved as new data becomes available and as experience grows in using the system.
The wetland DSS is based on a multi-criteria assessment method to determine wetland priorities and allows different alternative views to be assessed through weighted measurable criteria. Criteria were developed and then assessed and weighted in a series of expert panel and stakeholder workshops. Weighting allowed for value judgements to be made about the criteria and their importance when making a decision.
Criteria groupings of the method
Wetland values, threats and capacity generated by analysis of available data, current NRM frameworks, wetland types and different decision makers and stakeholders in the GBR catchment.
Facilitator familiar with use of the DSS and understanding of the criteria, participants with high level of information on the criteria, assumptions and uncertainties.
MS Excel workbooks, DSS Primary and Secondary tools, spatial datasets.
Criteria by category
Physical and chemical
Management and planning
Natural resource managers, including NRM bodies, community groups, government agencies, local government.
