THE APPLICATION OF WEB-BASED DECISION SUPPORT TOOLS AND THE VALUE OF LOCAL INFORMATION IN PRIORITIZING BARRIER REMOVAL IN NORTHWEST LOWER MICHIGAN, USA
Connectivity loss in freshwater ecosystems has threatened both biodiversity and ecosystem services worldwide, but restoration projects are usually costly, time-consuming, and require the consideration of trade-offs among multiple objectives. Web-based decision support tools (DSTs) have been developed to facilitate decision-making processes in watershed management by providing ecological and socio-economic data, spatial analysis models, and visualizing the result. However, DSTs are underutilized by decision makers, regardless of the usefulness of these tools. In this study, we reviewed eight web-based DSTs, evaluated their performance under limited data, and revealed the complementarity among DSTs to address some key concerns from managers and stakeholders. Restoring habitat connectivity in rivers of northwest lower Michigan, USA, was used as a case study due to the abundance of both DSTs and local inventory data. The results suggested that while some DSTs could produce outcomes insensitive to local data availability, the trade-offs among users’ objectives might influence the cost and effectiveness of DSTs’ outcomes. Improving DSTs’ ability to incorporate objectives consistent with policy and from multiple stakeholders across management scales can mitigate the gap between DSTs and management decisions while making the process transparent and efficient.
