Decision Support to Improve Ridge-to-Reef Stewardship in an Era of Rapid Global Change Decision Support to Improve Ridge-to-Reef Stewardship in an Era of Rapid Global Change Our research team will deliver five new applied research products: (1) quantificationof how variation in the climate, wildfire, biological invasion, land-use, and diseaseprogression impact freshwater flow regimes, rates of carbon sequestration, and ridge-to-reef ecosystem health (Year 1); (2) prescriptions for stand-level stewardship at sub-catchment, watershed, and island-wide scales (Year 1 & 2); (3) evaluation of modeled stewardship outcomes (Year 2); (4) collaboratively built mitigation prescriptions and prescription evaluation criteria (Year 1 and 2); and (5) coproduced (Year 2 & 3) data and model-based landscape stewardship scenarios and a decision support tool(s) that can transparently reveal stewardship trade-offs and synergies. These products will support stewardship for freshwater resource conservation, carbon sequestration, and enhanced health of ridge-to-reef ecosystems. This suite of approaches will accelerate our understanding of current and future states of water resources, carbon storage and flux, and ridge-to-reef ecological health. Similarly, we will use in-hand and in-house empirical and forecasted datasets to model the spatial and temporal dynamics of water flux from vegetation, surface, groundwater, and near-shore sources in response to changing climate, land use, and non-native plant and pathogen spread. Finally, these actionable data products will used to collaboratively develop realistic stewardship scenarios and a decision support tool designed to optimize stewardship for site specific outcomes across ridge-to-reef systems of Hawaii Island. Scientifically, this co-production approach will engage the many factors that drive restoration success including: site-specific stewardship costs including accessibility and proximity, priority based on ecological and cultural value of the land unit being considered, geospatial information (extent and biomass of non-native species, soils, ownership type), as well as biocultural knowledge of stewardship practices for place. The work also will provide an unprecedented level of synthesized information that managers need to plan the recovery of Hawaiis native forests.
