Discover Curaçao’s Biodiversity Through Citizen Science
Curaçao is one of the most biodiverse islands within the Dutch Caribbean, boasting a remarkable variety of flora and fauna both above and below the surface. From vibrant coral reefs teeming with marine life to lush terrestrial habitats housing unique plant and animal species, this Caribbean paradise is a biodiversity hotspot. However, many of these species remain undocumented, making events like the City Nature Challenge Curaçao crucial for conservation and research.

What is the City Nature Challenge?
The City Nature Challenge (CNC) is a global event that encourages people to explore and document local biodiversity using the iNaturalist app.
Originally launched in 2016 as a friendly competition between Los Angeles and San Francisco, it has grown into a worldwide initiative involving over 1,000 cities.
This event provides a unique opportunity for citizen scientists, divers, nature lovers, and conservationists to contribute to scientific research while enjoying the beauty of their natural surroundings.
Why Curaçao Needs You!
Curaçao’s ecosystems are home to a vast array of species, including over 65 species of hard corals, hundreds of species of fish, rare seabirds, endemic reptiles, and diverse coastal and terrestrial plants. The more species we document, the better we can understand and protect them. By participating in the City Nature Challenge Curaçao 2026 (April 24-27, 2026), you can play a direct role in biodiversity conservation.
Curaçao is a Coral Island Worth Protecting
Curaçao’s rich geological history and a vibrant marine ecosystem supports its ecological and economic well-being.

- Capture images from different angles for better species identification.
- Upload your findings to iNaturalist with accurate location details.
3. Explore & Identify: Land-Based Biodiversity
Not a diver? No problem! Curaçao’s terrestrial ecosystems are just as fascinating. Take a nature walk and document:
- Native plants (cacti, mangroves, orchids)
- Birds (flamingos, hummingbirds, warblers)
- Insects (butterflies, bees, beetles)
- Reptiles (whiptail lizards, iguanas, snakes)
- Mammals (bats, rabbits, deer)
Tips for Better Observations:
- Focus on wild species—no pets or potted plants.
- Take close-up shots for better identification.
- Use iNaturalist’s AI assistance for species suggestions.

Curaçao’s Biodiversity: Why It Matters
A Marine Paradise
Curaçao’s coral reefs are home to some of the most diverse marine life in the Caribbean. The island sits outside the hurricane belt, allowing for healthy reef ecosystems to flourish. Our waters host:
- Over 400 species of fish, including endangered species.
- Rich seagrass beds that serve as nurseries for young marine life.
- Flourishing mangrove forests that protect coastlines and provide habitats for marine and bird species.
A Unique Terrestrial Landscape
On land, Curaçao’s biodiversity is equally impressive:
- Christoffel National Park is home to rare orchids, native bats, and the Curaçao White-tailed Deer, one of the rarest mammals in the Caribbean.
- Shete Boka National Park shelters endangered sea turtles nesting along the rugged coastline.
- Flamingo sanctuaries in the salt flats attract migrating and resident flamingos year-round.
By documenting these species, we can monitor their populations and support conservation efforts.
ID and Validator Kick Off Event: April 28, 2026
Help Verify Observations & Celebrate!
After the observation period ends, there will be an ID and Validation Kick Off Event on April 28, 2026. This event will be held at the Biblioteka Nashonal Korsou where marine biologists, conservationists, and nature enthusiasts are invited to:
- Verify species identifications on iNaturalist.
- Ensure data accuracy for scientific research.
- Network with other ocean lovers over food and drinks.
Whether you’re an expert or just eager to learn, this is a fantastic way to contribute while celebrating Curaçao’s biodiversity.
