Belize's Marine Ecosystem: The Living Wealth of San Pedro

The Belize Barrier Reef Reserve System: Structure, Diversity, and Value

The Belize Barrier Reef Reserve System (BBRRS) is a natural wonder running more than 185 miles (297.73 km) along the coastline, forming an intricate chain of coral reefs, offshore atolls, several hundred cays, mangrove forests, and seagrass meadows. The BBRRS encompasses seven protected sites, including the Hol Chan Marine Reserve—San Pedro’s primary marine attraction—and is famed for its rich habitats supporting over 500 fish species, 65 coral species, and numerous marine mammals, turtles, and seabirds.

Central to Belize’s economy, the reef supports fisheries, provides coastal protection, sustains tourism revenues, and secures food resources for more than 40% of Belize’s population. The coral reefs and adjoining ecosystems, such as mangroves and seagrass beds, are interconnected—the destruction of one habitat can ripple across the entire system, affecting both biodiversity and human livelihoods.

Key Habitats and Their Functions

• Coral Reefs: The backbone of biodiversity, providing habitat, breeding, and feeding grounds for marine species, and acting as natural breakwaters against storms7.

• Seagrass Beds: Essential for manatees, turtles, and juvenile fish, seagrass meadows also trap sediments and improve water clarity.

• Mangroves: Nurseries for fish and crustaceans, barriers to coastal erosion, and vital for carbon sequestration.

The Economic and Social Value

The economic services provided by the reef—including fisheries, tourism, and coastal protection—are estimated to be worth over US$500 million annually for Belize, underscoring the high stakes involved in conserving this ecosystem. San Pedro, as a gateway to marine tourism, sits at the heart of this blue economy, balancing job creation, community well-being, and resource sustainability.

The State of San Pedro’s Coral Reefs: Threats, Trends, and Conservation Status

Recent Challenges to Reef Health

Despite its resilience, the Belize Barrier Reef has not been immune to global and local stressors. The last decade has seen worsening coral bleaching, climate-induced stress, and disease outbreaks. The 2023–2025 period was particularly severe, with the fourth recorded global coral bleaching event impacting the Mesoamerican Barrier Reef—including Belize’s portion—with temperature-induced bleaching, reductions in live coral cover, and increases in coral disease prevalence.

Main Threats to San Pedro and Belize’s Coral Reefs:

• Coral Bleaching and Thermal Stress: Elevated water temperatures have led to multiple bleaching episodes, most recently in 2023–2024, reducing coral resilience and increasing vulnerability to disease.

• Coral Disease: Stony Coral Tissue Loss Disease (SCTLD) has rapidly spread since its 2019 appearance in Belize, leading to high coral mortality in certain sites.

• Overfishing: Overexploitation of herbivorous and predatory fish, particularly before the ban on harvesting parrotfish in 2009, altered ecological balances vital for reef health.

• Pollution and Sedimentation: Inadequate wastewater management, agricultural runoff, and plastic pollution degrade water quality and exacerbate algal overgrowth on reefs.

• Coastal Development: Expansion of tourism infrastructure disrupts sensitive habitats (mangroves, seagrasses), contributing to erosion and habitat fragmentation.

Detailed Discussion

Coral species such as Elkhorn and Staghorn corals have been hardest hit, pushed to the brink of extinction by disease, bleaching, and storm damage. Over 80% of some key coral populations have been lost since the 1980s. Reef fish, notably the Nassau grouper, were once a staple of Belizean fisheries but are now protected with strict seasonal closures, size limits, and no-take zones during spawning.

Yet, the news is not all grim: Intensive coral restoration, new fishing regulations, and increased stakeholder awareness are producing real, positive changes in reef resilience and biodiversity—a testament to what community-centered, science-based interventions can achieve.

Key Reef Fish, Sharks, and Endangered Species: Profiles, Status, and Protection

Reef Fish Biodiversity in San Pedro

Hol Chan Marine Reserve and its surrounds are teeming with reef fish—parrotfish, snapper, angelfish, grouper, and wrasse—each playing a unique role in maintaining coral health.

Notable Fish:

• Parrotfish: As primary grazers, they keep algae in check, ensuring coral larvae can settle and thrive. Banning their harvest was a turning point for reef recovery in Belize.

• Nassau Grouper: A keystone predator, now endangered due to historical overfishing at predictable spawning sites; subject to strict protection and closed seasons.

• Snappers and Wrasses: Contribute to the food web’s complexity and are indicators of overall reef health.

Shark Species: Guardians of Belize's Reefs

Belize’s waters, especially near San Pedro, support a diversity of shark species, from docile nurse sharks at Shark Ray Alley to the occasional awe-inspiring.

Key Sharks and Their Protection:

• Nurse Shark (Ginglymostoma cirratum): Plentiful in shallow reef waters; their protection has contributed to Belize’s marine tourism appeal.

• Caribbean Reef Shark, Blacktip, and Hammerhead: Present in deeper and atoll waters, crucial for maintaining the trophic structure; most are now regulated through licensing and closed seasons, with certain atolls designated as total no-take zones for sharks.

• Whale Shark (Rhincodon typus): The world’s largest fish visits Belize from March to June for seasonal feeding, protected through regulated, low-impact ecotourism.

All shark fishing for critical species and within designated marine reserves is subjected to permits, with outright bans for threatened species and moratoriums on finning and meat exports during closed seasons19.

Antillean Manatees: Belize’s Gentle Giants

Belize is home to the Caribbean’s largest population of Antillean manatees, with hotspots near Belize City and southern lagoons—but their numbers near San Pedro are lower, reflecting ongoing threats from boat collisions, habitat loss, and pollution.

Conservation status: Endangered, protected under Belizean and CITES laws.

Key threats: Boating traffic (collisions), fishing gear entanglement, and degraded water quality. Notably, the number of fatal manatee-boat collisions has increased as tourism and watercraft traffic grew. Conservation interventions include speed limits, establishment of no-wake zones, and education for boat operators and tour guides.

Tour operator engagement: Operators in San Pedro and nearby marine reserves participate in observation, reporting of sightings and strandings, and public awareness—reinforcing manatee protection across their habitats.

Sea Turtles: Iconic and Imperiled

Three sea turtle species nest and forage around Ambergris Caye: Loggerhead, Green, and Hawksbill turtles. The loggerhead and green turtles commonly nest on nearby beaches, including Robles and Rocky Point, while hawksbills are rarer but can be seen in deeper reef areas and atolls.

Recent status:

• Loggerhead and Green Turtle: Endangered (IUCN); protected by Belize law and subject to rigorous nest monitoring and protection during nesting season (May–November).

• Hawksbill Turtle: Critically endangered; vulnerable due to egg harvesting, illegal shell trade, and habitat disturbance.

Tour operators engage with turtle monitoring programs (e.g., Hol Chan Marine Reserve’s Turtle Project), and visitors are routinely briefed on responsible turtle viewing. Disturbing nests, handling turtles, or purchasing turtle-shell souvenirs is strictly illegal.

The National Red List: Belize’s At-Risk Marine Species

The 2025 National Red List of Threatened Species for Belize highlights the vulnerability and endangered status of multiple coastal and marine species, influencing conservation prioritization, enforcement, and tourism regulations.

Coral Restoration and Community Action: Success Stories from San Pedro and Belize

The Power of Coral Restoration: Fragments of Hope at Laughing Bird Caye

Belize is credited with one of the Caribbean’s premier coral restoration stories: the work of the non-profit Fragments of Hope (FOH), which has pioneered large-scale replanting of critically endangered Elkhorn and Staghorn corals since 2006.

Results and Impact:

• Over 160,000 nursery-grown corals have been out-planted across multiple Marine Protected Areas, with >80,000 at Laughing Bird Caye alone.

• Restored sites show consistently higher survival rates during bleaching events compared to natural stands—demonstrating the value of genetic diversity and community engagement.

• FOH collaborates with local fishers and guides, training them not just as coral gardeners but as reef stewards and educators for visiting tourists.

Building Resilience: Workshops and Post-Storm Response Initiatives

San Pedro was the location for recent capacity-building events—including a 2025 multi-stakeholder coral protection workshop and specialized post-storm response training for reef brigades. These initiatives, supported by NGOs, the Ministry of Blue Economy, and international conservation partners, equip community members, tour guides, and scientists to monitor reef health, conduct rapid response after hurricanes, and restore damaged corals.

Stakeholder consultations, a hallmark of Belize’s approach, ensure that ecological science is paired with traditional and local knowledge—balancing conservation with economic realities in a way that resonates both locally and globally.

Community-Based Marine Planning: San Pedro at the Heart of Bold Belize

The Resilient Bold Belize Initiative and Marine Spatial Planning

Belize’s national Marine Spatial Planning (MSP) process, under the Resilient Bold Belize (RBB) initiative, represents a bold new framework for sustainable ocean management. The vision: expand high- and medium-biodiversity zones to protect up to 30% of Belize’s ocean territory by the end of 2026, with an immediate goal of tripling coral reef protection from 7% to 20% by 2025. San Pedro, as a stakeholder-intensive site, has hosted workshops where fishers, tourism representatives, and community groups help identify priority conservation areas, assess impacts (e.g., sargassum influx), and propose solutions that don’t displace jobs or traditional activities.

Key aspects of Belize’s marine spatial planning and its relevance for visitors:

• Community Empowerment: Policies are shaped through bottom-up consultation, empowering stakeholders including tour operators, fishers, and residents.

• Zoning: New biodiversity protection zones prioritize non-extractive uses—especially ecotourism and scientific research—while restricting fishing, anchoring, and extractive activities.
