Cần Giờ Mangrove Forest is a coastal wetland and mangrove ecosystem located in the Cần Giờ district of Hồ Chí Minh City in southern Vietnam. Designated as a UNESCO MAB biosphere reserve in 2000, it lies near the mouths of the Saigon River and the Dong Nai River, acting as a buffer between urban Hồ Chí Minh City and the South China Sea. The area combines tidal wetlands, estuaries, lagoons and upland zones, forming a landscape shaped by riverine and marine processes and influenced by regional infrastructure such as the Phu My Bridge and the Ben Tre–Tra Vinh Coastal Road.

Geography and Environment

The forest occupies a deltaic plain at the southeastern edge of Hồ Chí Minh City adjoining the Tiền River distributary and the Vam Co River system, with elevations near mean sea level and extensive tidal flats. Geomorphology reflects sedimentation from the Mekong River and the Dong Nai River, coastal dynamics of the South China Sea, and human interventions like the Saigon River Tunnel and regional dike construction. The climate is tropical monsoon, with influences from the South China Sea monsoon and occasional effects from Typhoon Durian-scale storms, producing wet and dry seasons that determine salinity gradients and mangrove zonation. Hydrological connectivity links to the Saigon River Delta, adjacent estuaries, and regional aquifers affected by groundwater withdrawal in Hồ Chí Minh City and neighboring Dong Nai Province.

History and Conservation

Historically, the area was inhabited by communities associated with the Nguyễn dynasty coastal economy and later impacted by colonial-era development under French Indochina, wartime operations during the First Indochina War and the Vietnam War, including campaigns that influenced land use and mangrove cover. Post-war reclamation and aquaculture expansion mirrored national policies such as land reforms associated with the Đổi Mới economic reforms and state forestry projects. Conservation milestones include designation under the Ramsar Convention-related wetland initiatives, recognition by UNESCO as a biosphere reserve, and management plans influenced by international programs like IUCN initiatives and bilateral partnerships with agencies from Japan, Australia, and the World Bank. Restoration projects have drawn on experiences from mangrove rehabilitation in Bangladesh, Thailand, and programs associated with the Asian Development Bank.

Biodiversity

The reserve supports mangrove species such as Sonneratia alba, Avicennia alba, and Rhizophora apiculata, alongside salt-tolerant vegetation and seagrass beds that provide nursery habitat for estuarine fishes linked to fisheries of the South China Sea. Fauna includes populations of Long-tailed macaques historically reported in the region, a variety of coastal bird species observed in inventories parallel to those at Lancang-Mekong wetlands, and estuarine crustaceans exploited by local fisheries. The site functions as habitat for migratory waterbirds on flyways connected to the East Asian–Australasian Flyway and hosts amphibians and reptiles comparable to assemblages in Cat Tien National Park and Con Dao National Park. Biodiversity assessments have employed methods similar to those used in Smithsonian Institution and WWF coastal studies, documenting ecosystem services including carbon sequestration akin to blue carbon projects at Sundarbans and sediment trapping comparable to mangrove systems in Borneo.

Human Use and Tourism

Local livelihoods combine traditional fishing, aquaculture, honey collection, and small-scale agriculture shaped by policies from Hồ Chí Minh City People's Committee and provincial administrations. Community-based management models reference frameworks promoted by CARE International and Oxfam for sustainable coastal resource use, and ecotourism initiatives echo models from Phu Quoc and Ha Long Bay with boat-based tours, canopy walkways, and interpretive centers. Tourist access connects via routes from central Hồ Chí Minh City served by regional transportation infrastructure like the Ho Chi Minh City–Long Thanh–Dau Giay Expressway and local ferry services. Educational programs collaborate with institutions such as Vietnam National University, Ho Chi Minh City and NGOs, balancing visitor services and conservation goals while confronting pressures from urban expansion, industrial zones like Cai Mep–Thi Vai Port and proposed coastal development projects.

Management and Protection

Management is administered by the People's Committee of Cần Giờ District in coordination with the Hồ Chí Minh City Department of Agriculture and Rural Development and national agencies including the Vietnam Administration of Forestry. Protection measures align with international guidelines from UNESCO MAB, IUCN protected area categories, and national legal instruments such as the Law on Biodiversity (Vietnam). Conservation strategies emphasize mangrove restoration, sustainable aquaculture, and integration of ecosystem-based adaptation to sea level rise scenarios studied by agencies like the IPCC and regional climate centers. Partnerships with international donors—examples include projects funded by the Global Environment Facility and technical assistance from FAO—support monitoring, capacity building, and community engagement, while enforcement addresses illegal logging and conversion pressures in coordination with the Vietnam People's Public Security and provincial environmental inspectorates.
