Covering over 50% of the island, Dominica's rainforests feature towering trees, dense undergrowth, high humidity, and exceptional biodiversity—including many endangered and endemic species.
At higher elevations, persistent mist creates cloud forests with stunted trees, epiphytes, and unique flora and fauna adapted to cool, saturated conditions. Many species exist nowhere else.
On the leeward (western) coast, lower rainfall supports dry forests with deciduous trees, open canopies, and species adapted to seasonal drought.
Coastal zones where saltwater meets freshwater host salt-tolerant mangrove trees, providing critical nursery habitat for fish and coastal protection.
Clear, warm coastal waters support vibrant coral reefs teeming with marine life—popular for snorkeling and diving.
Shallow coastal seagrass meadows stabilize sediment and serve as vital habitat for juvenile fish, conch, and sea turtles.
River mouths mixing fresh and saltwater create nutrient-rich nurseries for fish and crustaceans, supporting local fisheries.
Fast-flowing rivers cascade from the interior, providing freshwater, hydropower potential, and habitat for aquatic species like freshwater crayfish.
Inland lakes such as Boeri and Freshwater Lake offer recreation, habitat, and water supply.
Including salt marshes, mudflats, and mangroves, these transitional zones buffer storms and filter runoff.
Dominica's "Nature Isle" nickname reflects its extraordinary ecosystem diversity packed into a small area, much of it protected within national parks like Morne Trois Pitons (a UNESCO World Heritage Site).
