Costa Rica is known for its stunning biodiversity, lush rainforests, and pristine beaches. However, the country recently suffered a devastating environmental loss: the death of Jícaro Reef in Bahía Culebra, Guanacaste. The reef, once teeming with marine life, has succumbed to rising sea temperatures, uncontrolled tourism, and coastal development. This event raises urgent questions: How can travelers help protect Costa Rica’s marine ecosystems?

What Happened to Jícaro Reef?

According to researchers from CIMAR-UCR (Center for Marine Science and Limnology at the University of Costa Rica), Jícaro Reef experienced a total collapse due to coral bleaching, caused by prolonged ocean temperatures exceeding 33°C (91.4°F)—far above the ideal 28°C (82.4°F) for coral health (CIMAR-UCR). The reef had already been under stress from coastal development, pollution, and excessive tourist activity, which accelerated its demise.

The Importance of Coral Reefs in Costa Rica

Coral reefs are critical ecosystems that provide habitat for over 25% of marine species. They also protect coastlines from erosion and support local fishing and tourism industries. The loss of Jícaro Reef is a stark reminder of how climate change and human activities threaten these delicate ecosystems.

Responsible Tourism: How to Enjoy Marine Life Without Harming It

If you’re visiting Costa Rica and want to explore the marine world responsibly, here are some ways to minimize your impact:

1. Choose Sustainable Tour Operators

Opt for snorkeling and diving excursions with operators who follow strict eco-friendly guidelines. Look for businesses that:

• Use electric boats to reduce pollution.
• Limit the number of visitors to avoid overcrowding.
• Educate tourists about marine conservation.
• Follow the “Leave No Trace” principles.

🌱 Recommended Eco-Friendly Operators:

• Green Circle Experience (sustainable electric vehicle tours + eco-conscious experiences)
• Bahía Aventuras (responsible marine tours in Uvita)
• Dolphin Tour Costa Rica (certified dolphin and whale watching in the Golfo Dulce)

2. Use Reef-Safe Sunscreen

Many traditional sunscreens contain harmful chemicals like oxybenzone and octinoxate, which contribute to coral bleaching. Use mineral-based sunscreens made with zinc oxide or titanium dioxide (Environmental Working Group).

3. Respect Marine Life and Their Habitat

• Do not touch or step on corals. Even a slight touch can damage delicate coral structures.
• Do not feed marine animals. It disrupts their natural diet and behavior.
• Avoid using single-use plastics, which often end up in the ocean.

Conservation Efforts and How You Can Help

Costa Rica has long been a leader in marine conservation, but the country still faces challenges. Here are some initiatives you can support:

• Restoration Projects: Organizations like Raising Coral Costa Rica and Fundación Keto work on coral restoration by growing and transplanting coral fragments.
• Marine Protected Areas (MPAs): Support efforts to expand marine reserves, such as Cocos Island National Park, a UNESCO World Heritage Site.
• Citizen Science: Participate in volunteer programs that help monitor marine biodiversity.

The loss of Jícaro Reef is a wake-up call for conservationists, policymakers, and travelers alike. While climate change plays a significant role in coral bleaching, responsible tourism can help protect Costa Rica’s remaining marine ecosystems. By choosing sustainable travel options, respecting marine life, and supporting conservation efforts, visitors can help ensure that Costa Rica’s oceans remain vibrant for future generations.
