The Can Gio Mangrove Biosphere Reserve is located in the coastal district southeast of Ho Chi Minh City. The reserve provides opportunities to advance environmental protection across a continuum of habitats, ranging from coastal areas to the boundaries of Ho Chi Minh City, the biggest industrial city in Viet Nam. The mangrove forest hosts the highest diversity of mangrove plant species, mangrove-dwelling invertebrates and mangrove-associated fish and shellfish species in the sub-region, and is regarded as the ‘green lungs’ of the city.

Designation date: 2000

Ecosystem-based network: Tropical Forest and Mangroves

Surface : 75,740 ha

• Core area(s): 4,721 ha
• Buffer zone(s): 41,139 ha (terrestrial: 37,339 ha; marine: 3,800 ha)
• Transition zone(s): 29,880 ha (terrestrial: 29,310 ha; marine: 570 ha)

Location: 10°31’12”N – 106°53’35”E

Ecological Characteristics

The Can Gio mangrove forest grew out of a comparatively recent brackish swamp with soil foundations created by the Saigon and Dong Nai Rivers. The development of the mangrove forest is dependent on high precipitation and a high density of rivers interweaving the area, which provide a rich and plentiful supply of alluvium in the estuarine regions. The soil formed in Can Gio has been created by a combination of clay alluvial depositions, vitriolic processes and a brackish water table.

Can Gio encompasses diverse habitats including mangroves, wetlands, salt marshes, mud flats and sea grasses. The ecosystem functions as the ‘green lungs’ of Ho Chi Minh City absorbing carbon dioxide and other polluting agents on a daily basis.

The mangroves contain a high diversity of floral and faunal species. These include mangrove species such as Rhizophora apiculate, Thespesia populnea and Acanthus ebracteatus. A high number of faunal species appear in the biosphere reserve including king cobra (Ophiophagus Hannah), saltwater crocodile (Crocodilus porosus), spot-billed pelican (Pelecanus philippensis) and fishing cat (Felis viverrina).

Socio-Economic Characteristics

There are no communities living in the core area and buffer zone with the exception of forest protectors and their households, forestry staff and a few fishermen who operate traditional shrimp-trappers in some canals within the mangrove forest. A permanent population of almost 70,000 inhabitants lives in the transition zone of the biosphere reserve. These include groups of non-indigenous local people, the majority of whom are Vietnamese. Minorities located in the reserve include Chinese and Khmer communities living together in concentrated communes and towns in the transition zone.

The main economic activities are agriculture, aquaculture, fishing, salt-pan, trading and tourism. Revolutionary forces made active use of the region during the wars against France and the United States of America in the nineteenth and twentieth centuries.

2. Dong Nai Biosphere Reserve

Dong Nai is the new name of the former Cat Tien Biosphere Reserve, which was designated in 2001. It is located in the Dong Nai province in the south-east of Viet Nam. In this region the plateaux of the central Vietnamese highlands give way to the Nam Bo Delta. The area includes typical landforms of the Truong Son Mountain range and the lowland rivers, streams, semi-plains, medium hills, relatively flat lands and scattered lakes, ponds and wetlands of the eastern Nam Bo Delta.

Designation date: 2001

Ecosystem-based network: Tropical Forest and Wetlands

Surface : 969,781 ha

• Core area(s): 172,223 ha
• Buffer zone(s): 346,844 ha
• Transition zone(s): 450,714 ha

Location: 11°35’35”N – 107°22’12”E

Ecological Characteristics

The Cat Tien tropical forest ecosystem forms part of the Indo-Pacific Biogeographical Region. Typical forest types include evergreen broad leaves forest, bamboo forest and other mixed forest. Cat Tien National Park provides protection for this continuous mosaic of forests. Within the park there is great variation in topography from steep hill areas in the north to large lowland areas, wetlands, riverine areas and cultivated fields in the south.

The area has been able to retain much of its original diversity due to the survival of areas of unmodified habitat and the suppression of hunting and other forms of disturbance. There are seven different habitat types and a total of 1,610 botanical species on five geographical landscapes. Of the known species 31 are listed as rare and 23 are endemic to Cat Tien.

The forest types and geographical sites function as habitats for the unique tropical fauna which include 6,085 species of mammals, 259 bird species, 64 reptile species, 33 amphibian species and 99 fish species. These include endangered species such as white-shouldered ibis (Pseudibis davisoni), Indochinese tiger (Panthera tigris corbetti), Asian elephant (Elephas maximus) and the critically endangered Javan Rhinoceros (Rhinoceros sondaicus annamiticus), one of the world’s rarest large mammals.

Socio-Economic Characteristics

There are 11 different ethnic groups living within the biosphere reserve. They can be divided into three main groups, which have different histories in the area and differ in land use strategies. These groups include recently migrated minorities from Northern provinces (such as Tay, Nung, Dao and H’mong), the Kinh or lowland Vietnamese, and the S’Tieng, Chau Ma and Chau Ro indigenous ethnic minorities that have lived in the region for several centuries.

Agriculture is the key production sector accounting for the livelihoods of about 90% to 95% of local people. Other main economic activities include tourism, aquaculture and fishing.

3. Cat Ba Biosphere Reserve

• Core area(s): 8,500 ha (terrestrial: 6,500 ha; marine: 2,000 ha)
• Buffer zone(s): 7,741 ha (terrestrial: 4,941 ha; marine: 2,800 ha)
• Transition zone(s): 10,000 ha (terrestrial: 5,600 ha; marine: 4,400 ha)

Location: 20°47’42”N – 107°00’38”E

Ecological Characteristics

The Cat Ba Biosphere Reserve is considered part of the Indochinese rainforest biogeographical province. It includes tropical humid forests, wetlands, mangroves and coral reef ecosystem types. The northern coastal region of Viet Nam has a humid, tropical monsoon climate with distinct wet and dry seasons. The area suffers from a high frequency of typhoons with 28% of all typhoons impacting the Vietnamese coastline appearing in this area.

There are 2,026 species found in the biosphere reserve including 199 phytoplankton, 89 zooplankton, 75 forms of seaweed, 23 types of mangrove, 160 corals, 475 zoobenthonic organisms, 119 fish, three seagrasses, 142 species of terrestrial fauna and 741 plants.

Many species are endemic and rare, the most significant being the globally important Golden-headed langur (Trachypithecus poliocephalus), restricted in range to Cat Ba Island, the largest of the 366 islands, and found nowhere else in the world.

The Hawksbill turtle (Eretmochelys imbricata) found in the Cat Ba region is inscribed on the IUCN Red List, while the seahorse (Hippocampus spp.) is also rare and threatened. Mangroves and seagrasses on Cat Ba function as nurseries for life in the bay and as protective buffers for local inhabitants from storm surges and typhoons driven by climate change and sea level rise.

Socio-Economic Characteristics

Cat Ba Island and its marine waters have a long history of human utilization for subsistence and cash crop agriculture, fishing, aquaculture and mariculture. Based on the evidence of archaeological remains, people have inhabited the Cat Ba area for at least 6,000 years ago. Two ethnic groups currently live in the area: the Kinh and Chinese-born Vietnamese. These ethnic groups are intermingled and not separated into different areas or communities.

The main economic activities are agriculture, fishing and hunting, with tourism also functioning as a key industry. The biosphere reserve has 42 archaeological sites containing prehistoric relics with traces from the Pleistocene era. Cultural artefacts and monuments on the island of Cat Ba include the remains of the temples Cac Ba and Cac Ong, while ancient citadels of the Mac dynasty are found on Xuan Dam. A number of festivals are celebrated including the dragon-shaped boat race, the Sea God ceremony and several fishery festivals all of which constitute popular tourist attractions.

4. Red River Delta Biosphere Reserve

Location: 20°32’11”N – 106°34’48”E

Ecological Characteristics

The Red River basin is shared by China, Laos and Viet Nam. The main Red River is approximately 1,140 km in length and covers over 500 km in Viet Nam. The coastal areas of the Red River Delta support a complex system of natural, semi-natural and agricultural vegetation types. The natural vegetation consists mainly of salt tolerant species and plant communities, including mangrove, salt marsh and dune vegetation.

The mangrove ecosystem comprises the mangrove forest and the adjacent intertidal area, which represent a transitional zone between the marine and terrestrial environments. There are 26 mangrove species found in the coastal zones of which the most dominant are Kandelia candel and Sonneratia caseolaris.

During spring and autumn migrations, huge numbers of birds stop on route from their breeding grounds in northern Asia to their wintering sites in the Indo-Malaysian and Australian regions. A total of 78 species of water birds have been recorded in the Red River Delta including 38 species of shorebirds. Eleven of these birds fall under the category of threatened or near-threatened species, including spoonbill sandpiper (Calidris pygmaea), black-headed ibis (Threskiornis melanocephalus) and Japanese paradise flycatcher (Terpsiphone atrocaudata).

Other animal species found in the reserve include the saltwater crocodile (Crocodylus porosus) and the seacow or Dugong (Dugong dugon).

In recognition of the fundamental ecological functions performed by its wetlands, Xuan Thuy was declared the first Vietnamese Ramsar Site in 1982.

Socio-Economic Characteristics

The Red River Delta consists of several ethnic groups resulting in a diverse culture. Families inhabiting the forest generally have two houses, one in the forest and one in town. The main economic activities are agriculture and fishery.

There are five large clans in the area. Each clan has several houses of worship dedicated to its founder-ancestors and large branches of a clan may build separate houses of worship of their own. There are 29 such houses of worship overall. The annual clan celebration gathers together the members of each clan and helps to strengthen relations and foster communal bonds.

The area is linked to many rivers and waterways leading to the Pacific Ocean and the Gulf of Thailand. These rivers receive alluvium from Cuu Long River, deposited mostly on the northwest side by sea currents, where it accumulates creating foundations for the development of mangrove forests.

The Mui Ca Mau Biosphere Reserve hosts a rich and varied biodiversity resulting from three types of ecosystem: marine, mangrove and a closed tropical rainforest ecosystem. Characteristic species include Bui (Ilex cymosa), Mop (Alstonia spathulata), Melaleuca forest (Melaleuca cajeputi), three-leave Dau dau (Euodia lepta) and Tram (Syzygium cinereum).

Due to its rich biodiversity many different species can be found in the area. These include the lesser short-nosed fruit bat (Cynopterus brachyotis), crab-eating macaque (Macaca fascicularis), lesser adjutant (Leptoptilos javanicus), painted stork (Mycteria leucocephala) and spot-billed pelican (Pelacanus philippinensis).

Socio-Economic Characteristics

About 20 ethnic groups inhabit the area the majority of which belong to the Kinh (more than 95%). Other groups include the Khmer and Hoa-Chinese. Major economic activities are agriculture, aquaculture, fishery and tourism.

Over 40 relics have been found in the Mui Ca Mau area. Several of these have become tourist attractions including the Quan Am Co Tu and Hung Quang pagodas and the Tan Hung temple. Another attraction is the Ca Mau floating market, situated in the middle of Ca Mau city on the Ganh Hao River.

The Cultural World Heritage Site of Hoi An is an ancient trading port bearing witness to the fusion of Vietnamese and European cultures.

Designation date: 2009

Ecosystem-based network: Tropical Forest and Marine, Coastal and Island Areas

Surface : 33,146 ha

• Core area(s): 2,471 ha (terrestrial: 257 ha; marine: 2,214)
• Buffer zone(s): 8,455 ha (terrestrial: 2,410 ha; marine: 6,045 ha)
• Transition zone(s): 22,220 ha (terrestrial: 3,523 ha; marine: 18,697 ha)

Location: 15°15’20”N – 108°23’10”E

Ecological Characteristics

Topographical formations of maritime-marsh origin lie to the east of the township of Hoi An in the villages of Cam Chau, Cam An and Cam Thanh, and stretch along the coast south of the Thu Bon River running past Trung Phuong (Duy Xuyen district). The most typical are deposits found at Cam Chau, which reach a maximum height of 0.8–1.2 m and comprise black, muddy sediment indicating the presence of organic matter. These deposits provide evidence of ancient seas which receded leaving behind swamps and marshes that gradually filled up. They are approximately 2,000 years old.

There are two core areas where long-term conservation focuses on preserving land/seascape diversity with a view to conserving ecosystems, habitats, species and genetic resources intact, and preventing disturbance by human populations. The corridor between the two core areas is considered the ecological buffer zone and transition area linking the river mouth (Cua Dai) and the archipelago. This zone contributes substantially to the recovery of marine ecosystems in the area.

The area boasts a very rich biodiversity. According to research, there are 947 kinds of creatures living around the marine area of the islets, including 178 species of fish, 122 species of seaweed, 134 species of coral, 144 species of shellfish, 25 species of crustacean and many other marine species. Characteristic fish species include the coral grouper (Epinephelus coralicola), bumphead parrotfish (Bolbometopon muricatum), angelfishes (Pomacanthidae) and the endangered humphead wrasse (Cheilinus undulates).

Socio-Economic Characteristics

Approximately 84,000 people live in the area. Fishery is the main economic activity but tourism is regarded as a sector with strong economic potential.

During the sixteenth and seventeenth centuries, Hoi An was a meeting place for migrants from different parts of Viet Nam and people from other countries, especially Japan and China. Christoforo Borri’s memoirs and other documents of the time make clear that early seventeenth century Hoi An contained Japanese and Chinese districts, each with its own governor and regulations. Later on the Dutch East Indies Company established a trading post in the township.
