Introduction, Methods, and Caveats

Essential Fish Habitat (EFH) policy documents and current Ecosystem Status Report (ESR) indicators [1] were reviewed and aligned where possible, with gaps highlighted. Three key policy documents were reviewed in detail and aligned with existing indicators:

  • South Atlantic Food Webs and Connectivity Policy – January 2025
    • Connects EFH and food web considerations, identifies research needs
    • Includes fish food habits data identifying top 10 prey by FMP
    • Includes food web model for the South Atlantic region
  • Climate Variability and Fisheries – March 2018
    • Connects changing ocean conditions with fish distribution shifts and changing timing, identifies research needs
    • Notes these shifts present challenges for management and new fishery opportunities
    • Requests annual summaries of climate indicators tracking ecological, social and economic trends
    • Requests climate vulnerability analysis and management strategy evaluation focused on climate robustness
  • Marine Submerged Aquatic Vegetation - June 2014
    • Describes ecosystem services provided by SAV and recent declines in this EFH
    • Outlines monitoring and research, planning, management, and education and enforcement to protect and restore SAV

Additional policies identify species with EFH and HAPC potentially impacted by each activity, and identify specific threats, best management practices and research needs. These may be reviewed for alignment with existing indicators if time permits:

  • Beach Dredging and Filling, Beach Renourishment and Large-Scale Coastal Engineering – September 2023
  • Energy Exploration, Development, Transportation and Hydropower Re-Licensing - November 2024
  • Alteration of Riverine, Estuarine and Nearshore Flows Policy – June 2014
  • Artificial Reef Habitat Policy Threats to EFH – September 2017
  • Marine and Estuarine Non-Native and Invasive Species Policy – June 2014
  • Interactions Between Essential Fish Habitats And Marine Aquaculture Policy – June 2014

Policy objectives without current indicators were identified. Information gaps that might be filled with Citizen Science programs were then identified, along with what those programs would need to deliver.

All policy documents were reviewed by the author. Initial matches with ESR indicators were taken from the ESR summary which used Claude Sonnet 4.5 to produce a draft summary and R code to compile indicator descriptions as described here. After initial matches were made, pertinent ESR sections were reviewed by the author to validate matches and provide indicator details.

Policy Document Summary

South Atlantic Food Webs and Connectivity Policy

This document outlines 9 policies and 9 research and information needs.

Research needs are broader and so considered separate from policies here. Both are aligned with existing indicators in the following tables.

Overall, while two food web policy related indicators are reported in the 2021 ESR, at least 3 additional policies can be assessed with indicators derived from the existing food web model. Two others could potentially be addressed with more labor intensive updates to the existing food web model by integrating spatial capabilities and existing literature. Some literature information on invasive species diet is available [2,3]. Contaminant studies are not included in the ESR, perhaps due to limited work in the South Atlantic region [46].

High: many ESR indicators align with habitats

Research and information needs are already partially addressed by existing CVA [7,8] and ESR indicators, and by current MSE efforts [9]. Collaboration between the Council and NOAA/other partners to identify clear priorities and objectives for research is a practical next step. Many current ESR indicators have the potential to address specific Council needs; collaboration to tailor the indicators for specific uses is recommended. A structured decision process to identify and analyze ecosystem issues (similar to Pacific FEP Initiatives, North Pacific Action Modules, or Gulf Fishery Ecosystem Issues) could help achieve these goals.

Climate Variability and Fisheries

This document describes historical and projected ocean conditions in the South Atlantic, climate effects on fish, habitats, and fisheries, information gaps and research priorities, and relationships with SAFMC management. Here, stated management policies and research priorities are aligned with existing indicators. This policy was last updated in 2018, before the 2021 ESR and 2023 CVA were released.

Landings of currently unmanaged species

Moderate: resources required to compile information from multiple sources

Many current ESR indicators directly address Climate Variability and Fisheries policy statements. Current gaps related to species distribution shifts and forecast conditions could be filled with existing information. DisMAP indicators summarizing species distribution from the SEAMAP survey are available. Regional ocean model forecasts are available for the South Atlantic region, but resources are required to process, evaluate, and translate these outputs into indicators for management review. Some Councils already receive reports of unmanaged species landings compiled by NOAA Regional Offices. However, these reports focus on commercial landings because there are few information sources for recreational landings of unmanaged species.

Prioritize and tailor existing indicators to species based on CVA

Moderate: resource intensive depending on priority species

There are multiple ways to move forward with Climate Variability and Fisheries policies and research priorities given existing indicators and analyses. An initial step is collaborative Council and NOAA review of current indicators to prioritize a subset for refinement and annual updates. The CVA results could help identify a subset of species or a representative species for each FMP for initial focus. Considerable effort towards understanding the social and economic context and community climate vulnerability already exists [10,11] and can contribute to these efforts. Note that the last research priority here is identical to the second research priority identified in the Food Webs and Connectivity Policy.

Marine Submerged Aquatic Vegetation

Submerged Aquatic Vegetation (SAV) or seagrass is an important habitat in the South Atlantic, found primarily in North Carolina and Florida coastal waters. SAFMC has designated SAV to be Essential Fish Habitat (EFH) for managed fish (snapper-grouper species and cobia) and invertebrates (Penaeid shrimp and spiny lobster), as well as a Habitat Area of Particular Concern (HAPC) for snapper-grouper species.

The Council does not directly manage many of the activities and conditions that affect SAV. The overall policy goal in this document is to support actions that protect and restore SAV throughout the South Atlantic. These actions require collaboration with the four South Atlantic states: North Carolina, South Carolina, Georgia, and Florida, as well as local authorities.

High: subset of information from current indicators

Existing ESR indicators for SAV, coastal habitat attributes, land use and ocean economy align with SAV policy. Additional indicators of SAV benefits to dependent managed species could be derived from current indicators for commercial and recreational landings and value. However, comprehensive SAV indicators and research would require dedicated effort from multiple partners.

In general, research priorities for SAV require more coordination and collaboration with state and local partners relative to the priorities above for food web connectivity and climate fisheries interactions. However, the research objectives are clearly stated and well focused. Initial steps could include evaluation and prioritization of ESR indicators for relevance to SAV extent and % change. A longer term project could consider habitat-climate vulnerability analysis as was done for Northeast US Atlantic habitats [12], which would apply not just to SAV but to all Council designated EFH and HAPC.
