 Hikkaduwa Coral Reefs

 

Hikkaduwa coral reefs are located on the southwest coast of Sri Lanka, about 100 km south of Colombo . The reefs lie just offshore of Hikkaduwa town and are part of the Hikkaduwa Marine National Park, which was declared a wildlife sanctuary in 1979 and later upgraded to a national park in 2002.

 Hikkaduwa features fringing reefs, which grow close to the shore and are connected to the land. These reefs are among the most accessible and are known for their biodiversity and beauty. The reef supports over 60 species of hard corals and more than 170 species of reef fish. Common fish include parrotfish, butterflyfish, angel fish, groupers, and moray eels. It is also home to marine turtles such as the green turtle (Chelonia mydas) and hawksbill turtle (Eretmochelys imbricata).Sea cucumbers, starfish, and crustaceans like crabs and shrimps are also found in abundance.

According to the Department of Wildlife Conservation (Sri Lanka), Hikkaduwa’s reef is an ecologically important marine habitat that supports threatened and endemic species' study by the National Aquatic Resources Research and Development Agency (NARA) highlights that the coral cover in Hikkaduwa has significantly declined due to human activities but still retains critical habitat value.

 Environmental Threats are :

Coral bleaching caused by rising sea temperatures.

Pollution from tourism, especially from boats and beachside hotels.

Physical damage from people walking on corals or breaking them.

Overfishing and unsustainable snorkeling/diving practices

A 1998 global coral bleaching event affected over 90% of coral reefs in Sri Lanka, including Hikkaduwa (source: UNEP and IUCN reports).Research by IUCN Sri Lanka shows that despite partial recovery, coral health is still vulnerable due to ongoing pressure from tourism and pollution.

Hikkaduwa Marine National Park offers protection under Sri Lankan law, limiting fishing and coral collection, Coral replanting projects are ongoing to restore damaged reefs, Environmental education programs for tourists and local communities have been introduced. The reef is a major tourist attraction, drawing visitors for glass-bottom boat rides, snorkeling, and diving. Tourism provides local employment and income, but also increases pressure on the fragile ecosystem.

 Hikkaduwa coral reefs are a rich natural treasure of Sri Lanka, important for biodiversity, tourism, and environmental health. However, they are under threat from both natural and human pressures. Continued conservation efforts, awareness, and sustainable tourism practices are essential to protect this valuable marine ecosystem.
