Wildlife on St. Martin / Sint Maarten

Most part of the island is nowadays very developed, but still features a variety of habitats giving home to a great range of native and non-native fauna. Exploring St. Martin with an ‘experts eye’ and a close look, the interested traveler distinguishes species living in their natural habitat like coral reefs and sea grass beds, the lagoon in the center, many salt ponds, seaside forests and mangrove wetlands, ephemeral tropical forest up the hills and dry scrubland in the middle of the island.

St. Martin / Sint Maarten is proud of its natural heritage, and recently both sides of the island have created protection programs.

‘La Reserve Naturelle’ on the French side created a nature reserve, comprising sea and terrestrial areas. The Dutch side with its ‘Nature Foundation St. Maarten’ founded the ‘St. Maarten marine park’ including several small islands, and a terrestrial park is planned for the next future.
