Assessment purpose

 Management effectiveness, Prioritisation, Values/Services

Assessment criteria

 Socio-cultural, Significance, Physical and chemical, Management and planning, Flora, Fauna, Economic

Method type

 Desktop, expert panel

Timescale

 Medium term – The DSS could be re-run for the GBR catchments. Additional time would be required to use improved or new data. The DSS could also quickly be adapted for use in other regions with limited modifications.

Scale

 Landscape/Catchment, Region, Site/habitat

Wetland system

 Estuarine, Lacustrine, Marine, Palustrine, Riverine

Description and method logic

Method purpose

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.

Summary

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.

Method logic

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.

Review

Recommended user

Natural resource managers, including NRM bodies, community groups, government agencies, local government.

Strengths

  • Inherent flexibility which allows the system to be applied to multiple management objectives and outcomes.
  • Ability to use data in different formats.
  • Ability to work at multiple scales.
  • Ability to provide transparency to decision making process.
  • Enables ownership by decision makers.
  • Able to be updated as data is improved.

Limitations

  • Accuracy, availability and relevancy of the criteria data used in making the tool
  • Need to use in a workshop setting with facilitator familiar with system
  • System supports rather than makes decisions
  • Can't calculate amount of funding required for each wetland
  • Doesn't recognise individual wetlands in their catchment context or connectivity with other systems.
