Blue carbon ecosystems (BCEs), such as mangroves, saltmarshes, and seagrasses, are important nature-based solutions for climate change mitigation adaptation but threatened by degradation. Effective BCE restoration requires strategic planning site selection to optimise outcomes. We developed a Geographic Information System (GIS)-based multi-criteria decision support tool identify suitable areas along the 2512 km-long coastline of Victoria, Australia. High-resolution spatial data on distribution, coastal geomorphology, hydrodynamics, land tenure were integrated into flexible model that distinguishes between passive active suitability. The was applied high-priority locations mangrove, saltmarsh, seagrass across different scenarios. Results indicate substantial potential in with 33,253 ha area identified, mostly (>97%) public land, which aligned criteria used tool. Restoration opportunities concentrated bays estuaries where historical losses have been significant. mapped outputs provide decision-support framework regional planning, while itself can be adapted other geographies. By integrating multiple distinguishing restoration, our approach offers new method targeting informing resource allocation. identified will also require collaboration managers communities, consideration socio-economic factors. With further refinements, incorporating analysis techniques, GIS-based tools help catalyse blue investments contribute goals at scales. This study highlights value identification provides transferable regions.

ABSTRACT In this viewpoint, we provide a scientific justification for statewide, standardized, coastal wetland monitoring program Hawaiʻi, USA. Hawaiian wetlands important habitat endangered waterbirds, invertebrates, plants, and the hoary bat (ʻōpeʻapeʻa; Lasiurus semotus ) as well support Indigenous food systems. Currently, numerous agencies groups in Hawaiʻi collect data on wetlands, but information is not typically shared methods are standardized. A with centralized database would allow managers to keep better track of progress toward restoration goals, population changes conservation‐reliant species, outbreaks impacts avian botulism, rates salinization, many other critical issues across space time. Monitoring combined targeted research could fill knowledge gaps about types, functions, values, biodiversity wetlands. Ultimately, improved gained from long‐term inform landscape‐scale actions adaptive management under sea‐level rise climate change.
