The rich diversity of the ecosystems of Ha Long Bay, Lan Ha Bay, and Bai Tu Bay means that the areas have a high level of biodiversity in terms of both plant and animal species. This diversity isn’t just limited to the land, as the great variety in marine ecosystems present makes for a highly diverse marine life as well.
Most of the islets and islands are covered in vegetation
Many of the karsts are decorated with thick patches of subtropical, evergreen forests which cling to the islands. If it is the right season, many flowers such as orchids bloom on the rocks decorating the peaks with little bursts of colour. These cliff face gardens make the perfect habitats for coastal birds.
Monkeys are a common sight, with Cat Ba being famous for its endangered Cat Ba Lamur
The underwater landscapes of Ha Long Bay are equally as fascinating as those above sea level with areas of tropical ocean, salt water flooded forests, coral reefs and mangrove forests.
The diverse marine ecosystems means it’s a great place to do some snorkelling
The coral reef system is made up of 163 different species of coral which create a fascinating and colourful underground world whilst also proving a home for hundreds of species of marine wildlife including fish, shellfish, squid and cuttlefish. In addition to the colourful rainbows of fish, the bays are also home to larger animals such as seals and dolphins.
Mangroves are common and serve as the home of many different animal species
The tropical rainforests on the larger islands are home to many different types of mammals, including several endangered species. Deer, weasels, squirrels and different types of monkeys can be found in the larger forested areas.
