Panel hears evidence of seagrass decline and explores restoration, permitting and water-quality steps
Summary
Staff presented data showing high-salinity seagrass beds are shrinking (about 1% per year, with local rates higher), and the committee discussed regulatory gaps, restoration options and the need for a water-quality standard to protect SAV beds; public commenters urged active restoration pilots and funding.
DMF staff told the advisory committee that updated analyses show high-salinity submerged aquatic vegetation (SAV) beds in North Carolina are declining at roughly 1% per year from 2006–2020 and that continuous beds are fragmenting into patchy stands. Charlie Dean summarized APNEP findings showing concentrated losses along deep edges of beds and local losses approaching 3% per year in some places. "We're losing a little over 1% of our high salinity seagrass per year," he said.
Staff and committee members framed water quality—particularly light penetration related to nutrient and turbidity conditions—as the primary long-term driver of SAV decline. Dean said the nutrient-criteria work at the Division of Water Resources is moving slowly through regulatory channels and may not reach the Environmental Management Commission for a vote until 2027; he called a regulatory water-quality solution “our biggest issue.”
The CHIP will examine both passive and active restoration approaches. Dean said land-based culture of SAV plants may be permitted under existing aquaculture or collector permits, while in-water cultivation via bottom-leasing or restoration leases likely would require legislative action. He warned that donor-bed impacts, disease transmission and invasive-species risks will need monitoring and mitigation if transplanting or seed-based restoration expands.
Public commenters pressed for pilot projects and funding. "We already have a model that is successful," said Glenn Skinner, who described Virginia's eelgrass restoration program and urged the committee to prioritize restoration pilots and seek legislative funding. Chris Elkins, a recreational fishing stakeholder, urged that forage-fish dynamics and shrimp-trawl bycatch be accounted for in restoration and research planning.
Staff said they are working on permitting guidance within the CHIP and coordinating with partners (including The Nature Conservancy and APNEP) to clarify when active restoration is appropriate and what permitting steps would be required. Committee members encouraged staff to prepare short, practical materials and to bring draft chapters to the August meeting for more detailed review.
