National Park (NP) Con Dao has an area of 14,000 hectares nearly 6,000ha of land and water areas. The relationship of coral reefs, seagrass beds and mangroves have created a favorable environment for spawning, nursery and conservation of marine species. Shallow waters along the island is also home to many animal species distribution you like turtles, dolphins, dugongs (dugong) ... The biodiversity of the seas meant Con Dao National Nature Reserve marine in Vietnam.
gioithieu- As a relatively offshore islands, human activities do not change the nature of the large marine ecosystems. Coral reefs here retain the characteristics specific to the sea. The study showed that coral coverage was 42.6% average. In the study of coral reefs, with 74.2% of coral to achieve high coverage, only 2.8% of low government types. The density of reef fish in the study averaged 400 fish / m2. This value is very high compared to other coastal areas in Vietnam.
- Con Dao can be considered as a bridge to spread biological diversity from the center of the Indian Ocean - West Pacific to the coastal waters of Vietnam. Higher form of species of reef building corals. Ingredients molluscs are also considered the most diverse when compared to other national parks DAO
About biodiversity, shallow waters of Con Dao including coral reefs, seagrass beds and mangroves. In particular, coral colony is quite common, can be found in most coastal areas of the island. Type a fringing reef typically accounts for 59%, suggesting that this reef development conditions in a long time. Seagrass but not widely distributed but concentrated on large area, approximately 200 ha. Biodiversity facilitate the development of rare species. Research on the marine environment shows no marine pollution here.
Currently, Con Dao is the many sea turtles in Vietnam, with two common species of tortoise and the magnificent winter. There are 17 sand is recorded as breeding grounds of turtles, including four beaches are recognized as the mother turtle laying 1,000 annually. Con Dao is the only place in Vietnam exists a population of dugong (Dugong dugong) whose lives are inseparable from the sea grass.
To date, no studies on the relationship between coastal resources and ecosystems shallow Con Dao. Anyway, together with the existence of coral reefs, seagrass beds, mangroves and ecological relationship between them is a favorable environment for the breeding, nursery of many resources. The research of the Institute of Oceanography of fish eggs, larvae in Con Dao National Park to see the number of eggs was much higher than in other waters of Vietnam.
