NOAA Seeks Public Input on Expanded Coral Reef Conservation Efforts Through New Environmental Impact Review

The National Oceanic and Atmospheric Administration (NOAA) has initiated a critical update to its comprehensive strategy for coral reef preservation, announcing its intent to prepare a supplemental Programmatic Environmental Impact Statement (PEIS) for its Coral Reef Conservation Program (CRCP). This move, outlined in a Federal Register notice on May 19, 2026, signals a significant evolution in federal efforts to combat the escalating threats to coral ecosystems. The supplemental PEIS will assess the environmental implications of new and expanded conservation and restoration techniques, reflecting advances in marine science and the urgent need to adapt to shifting ocean conditions. Public input is currently being sought to help shape this vital environmental review.

Background of the Coral Reef Conservation Program

NOAA's Coral Reef Conservation Program operates under the mandate of the Coral Reef Conservation Act, which empowers the agency to protect, conserve, and restore coral reefs by maintaining healthy ecosystem functions and promoting sustainable use for the benefit of local communities and the nation. In July 2020, NOAA published its original PEIS for the CRCP, establishing a framework for assessing the environmental impacts of its funded activities. This foundational document has guided CRCP operations across various U.S. regions, including Florida, Hawai'i, Puerto Rico, and the U.S. Pacific Remote Island Area, as well as providing support to international regions like the wider Caribbean and the Coral Triangle. The program coordinates efforts across several NOAA line offices and collaborates with federal, state, local, and private organizations.

Evolving Threats and New Approaches

The decision to draft a supplemental PEIS stems from the recognition that scientific understanding and restoration methodologies have advanced considerably since the 2020 assessment. Furthermore, coral reefs face intensifying threats from diseases, invasive species, and fluctuating ocean conditions, necessitating more dynamic and adaptive conservation strategies. The original PEIS remains valid for its described activities, but the introduction of new actions and expanded methods requires a fresh environmental review under the National Environmental Policy Act (NEPA).

Key Expansions in Conservation Activities

The supplemental PEIS will specifically analyze the environmental impacts of several key expansions to the CRCP's toolkit. These include:

• Expanded Coral Collection: This involves collecting entire coral colonies for scientific research, for use in coral nursery broodstock, for large-scale restoration initiatives, for rescue during disease outbreaks and thermal events, and for long-term preservation in gene banks.
• Enhanced Nursery Operations: The program will increase support for land-based coral nurseries, including their expansion, maintenance, and the co-culturing of herbivores to assist in algae control.
• Larger-Scale Restoration: New restoration activities will cover larger areas, approximately 1,000 square meters (1,000 m^2), equivalent to two basketball courts. These efforts will incorporate selectively bred corals for improved genetic diversity, as well as preconditioned corals designed to be more resilient to environmental stressors. Advanced site preparation techniques, such as stabilizing loose coral and rubble and installing three-dimensional structures, will also be employed to enhance the survival of outplanted corals.
• Broader Ecosystem Interventions: This category includes propagating and releasing additional herbivores like fish and snails for algae control, implementing new methods to manage unwanted invasive and nuisance species such as soft corals, and exploring techniques to increase coral larval settlement through methods like playing natural sounds on reefs.
• Mitigating Ocean Condition Shifts: The program will expand its capacity to address temporary changes in ocean conditions, including thermal events and disease outbreaks. Strategies involve the temporary evacuation of corals to specialized ex-situ facilities, relocating coral nurseries to deeper, cooler waters, shading priority coral populations, and in-situ coral feeding.
• Watershed Restoration Integration: The CRCP will also broaden its watershed restoration activities to include in-situ mangrove nursery operations and restoration, recognizing the critical link between watershed health and coral reef vitality.

Framework for Environmental Review

NOAA will continue to employ a tiered environmental decision-making framework, established in the original PEIS, to ensure compliance with NEPA and other natural resource protection statutes. While the programmatic review assesses a broad range of potential impacts, actual environmental effects will be evaluated through site-specific, project-level reviews.

Alternatives Under Consideration

The supplemental PEIS will analyze four distinct program-level alternatives:

• No-Action Alternative: This alternative represents the continuation of CRCP operations as described in the original PEIS, without the integration of any new actions or expanded methods.
• Alternative One: This option proposes eliminating in-water activities aimed at restoring viable coral populations, such as in-water coral restoration and intervention techniques, and also removing activities that reduce physical impacts to coral reefs, like marine debris removal and buoy installations.
• Alternative Two: This alternative maintains the current CRCP operations, including in-water restoration and intervention activities and the reduction of physical impacts, essentially mirroring the no-action alternative, but it mandates the implementation of additional discretionary conservation and mitigation measures, and it includes the new actions and expanded methods.
• Alternative Three (Agency's Preferred): NOAA has identified this as its preferred alternative. It reflects the continuation of existing CRCP operations as outlined in the original PEIS, with the direct addition of all the new actions and expanded methods.

Public Participation is Crucial

The NEPA process commences with a public scoping period, inviting federal, state, and local agencies, as well as other interested parties, to contribute. The objective of this scoping process is to identify potential significant environmental impacts, substantial new circumstances requiring analysis, and to clarify issues that are insignificant or already addressed. It also seeks to identify related environmental documents and other review requirements. Written comments on this notice are due by June 18, 2026, and can be submitted via the Federal e-Rulemaking Portal or by mail.
