Evaluating management strategies to optimize coral reef ecosystem services: Ecosystem Model Data for Puako, Hawaii

Description

Coral reefs provide a wide range of ecosystem services that are valued differently by different users. Managers are challenged to comprehensively address the full suite of pressures that act simultaneously on these ecosystem state variables and dynamics. We developed a decision-support tool using an ecosystem model, Ecopath with Ecosim, that ranks the efficiency of potential management strategies in evaluating ecological and socio-economic trade-offs based on multiple indicators for coral reef ecosystem services in Puako, Hawaii Island. Our results indicate that current management is inadequate to prevent further declines in coral reef resources and that improved fishery management can mitigate the detrimental effects of expected bleaching-related coral mortalities on the ecosystem services in the next 15 years. The scenario that minimized conflicts between stakeholders was "Only Line Fishing" and to a lesser extent a reduction in fishing effort. Results include the biomass (tons per square kilometer) for several groups of marine organisms (invertivores, coralivores, planktivores, browsers, grazers, sharks, reef fishes, sea turtles, invertebrates, corals, algae, and plankton) for 2017 and 2032 under the current and alternative management scenarios and the relative performance of the indicators under six management scenarios in 2032 and compared to current management. The data are available from the Dryad Digital Repository: https://doi.org/10.5061/dryad.4sh45

0 Output data for Ecopath Puako modeling project. These data are the results of the EwE model output and were used to create the figures in the MS. The columns represent the alternative scenarios and the values are the model output biomass data per functional group. The first cluster (columns B-H) represent the biomass at the end of the simulations with a severe (50%) bleaching-related coral mortality and the second cluster (columns J-P) represent the biomass at the end of the simulations with a low (10%) bleaching-related coral mortality. https://datadryad.org/bitstream/handle/10255/dryad.168673/OuputDataSet.xlsx?sequence=1

0 Input data for Ecopath Puako modeling project. These data include: Table 1: Functional groups and vital rates. For each functional group it states, a number, trophic level, biomass (t/km2), the production to biomass ratio (per year), consumption to biomass ration (per year), the ecotrophic efficiency (unitless) and the production to consumption ratio. Table 2: Diet matrix. Each row is a prey group and each column is a predator. The values in the matrix are the proportions of prey items in the diet of the predator. Table 3: Vulnerability Matrix. Each row represents a prey group and each column a predator group. The values represent the vulnerability of that prey group to the predator. A high value represents a top-down control and a low value represents a bottom-up control. https://datadryad.org/bitstream/handle/10255/dryad.168672/EcopathInputData.xlsx?sequence=1
