Bangladesh is blessed with a diverse range of forests that play a crucial role in maintaining ecological balance and supporting biodiversity. Covering about 17% of the total land area of the country, forests provide livelihoods, environmental protection, and economic benefits. The forests in Bangladesh vary based on geography, climate, and biodiversity. This article explores the different types of forests found in Bangladesh, their locations, sizes, wildlife, forest resources, and their contributions to the country’s development.
Types of Forests in Bangladesh
Bangladesh has mainly three types of forests: Evergreen and Semi-evergreen Forests, Deciduous Forests, and Mangrove Forests. Additionally, there are smaller categories such as Social Forestry and Plantation Forests.
1. Evergreen and Semi-evergreen Forests
Location and Size
Evergreen and semi-evergreen forests are found mainly in the northeastern and southeastern regions of Bangladesh. The most notable ones include:
Chittagong Hill Tracts (CHT) – The largest forested region in Bangladesh.
Sylhet Division – Home to several smaller forest patches.
Mymensingh (Madhupur and Bhawal Garh) – Semi-evergreen forests.
These forests cover about 8,000 square kilometers, primarily in the districts of Bandarban, Rangamati, Khagrachari, Cox’s Bazar, Sylhet, and Moulvibazar.
Wildlife
These forests are rich in biodiversity, home to many rare species, including:
Mammals: Asian elephants, clouded leopards, barking deer, wild boars, and slow lorises.
Birds: Hill myna, hornbills, eagles, and various species of parakeets.
Reptiles: King cobras, pythons, and monitor lizards.
Forest Resources
These forests provide timber, medicinal plants, bamboo, fuelwood, and other non-timber forest products (NTFPs).
2. Deciduous Forests (Sal Forests)
Location and Size
Deciduous forests, locally known as Sal forests, are primarily found in:
Madhupur (Tangail, Mymensingh)
Bhawal (Gazipur)
Dinajpur
These forests once covered vast areas but have been reduced to around 2,000 square kilometers due to deforestation and agricultural expansion.
Wildlife
Though the biodiversity is lower than that of evergreen forests, some key species found here include:
Mammals: Rhesus macaques, wild boars, and jungle cats.
Birds: Woodpeckers, owls, and drongos.
Reptiles: Cobras and kraits.
Forest Resources
Sal trees (Shorea robusta) dominate these forests, providing high-quality timber used in furniture and construction. These forests also support honey production, mushrooms, and medicinal plants.
3. Mangrove Forests
Location and Size
The Sundarbans, the world’s largest mangrove forest, is the most significant forest in Bangladesh, covering about 10,000 square kilometers, spread across Khulna, Bagerhat, and Satkhira districts.
Wildlife
Mangrove forests host a unique ecosystem, supporting a variety of species:
Mammals: The famous Royal Bengal Tiger, spotted deer, wild boars, and otters.
Birds: White-bellied sea eagles, herons, and kingfishers.
Reptiles: Estuarine crocodiles, mudskippers, and snakes.
Aquatic Life: Fishes, crabs, shrimps, and dolphins.
Forest Resources
The Sundarbans provide timber (Sundari, Gewa, and Goran trees), honey, beeswax, and fishery resources.
4. Social Forestry and Plantation Forests
These forests are created through afforestation programs, primarily in:
Coastal areas (Noakhali, Barisal, Bhola) to prevent erosion.
Roadsides, embankments, and rural lands to provide livelihood and reduce deforestation pressure on natural forests.
Wildlife and Benefits
Though not as biodiverse, these forests attract small mammals and birds while providing timber, fruits, and firewood.
Role of Forests in National Development
1. Environmental Benefits
Carbon Sequestration: Absorbs COâ‚‚, reducing climate change effects.
Water Cycle Regulation: Prevents droughts and maintains groundwater levels.
Soil Conservation: Protects against soil erosion and desertification.
Biodiversity Conservation: Supports unique ecosystems and endangered species.
2. Economic Contribution
Timber and Non-Timber Products: Contributes to the economy through the furniture and construction industries.
Fisheries and Honey Production: The Sundarbans alone generate millions in revenue from fishery resources and honey collection.
Tourism: Nature tourism in the Sundarbans and hill tracts boosts local businesses.
3. Livelihoods and Community Development
Employment: Thousands of people, especially in rural areas, depend on forests for their income.
Social Forestry Programs: These create sustainable jobs for farmers and reduce pressure on natural forests.
4. Disaster Management
Coastal Protection: Mangroves act as natural barriers against cyclones and tidal surges.
Climate Resilience: Helps Bangladesh adapt to climate change by mitigating floods and erosion.
Challenges and Conservation Efforts
Despite their importance, forests in Bangladesh face significant threats:
Deforestation and Illegal Logging
Encroachment and Land Conversion
Climate Change and Rising Sea Levels
Poaching and Wildlife Trafficking
To combat these issues, the government and NGOs have initiated:
Afforestation and Reforestation Projects
Strict Forest Protection Laws
Community-Based Conservation Programs
Ecotourism and Awareness Campaigns
Conclusion
Bangladesh’s forests are invaluable assets that sustain biodiversity, provide economic benefits, and protect the environment. Preserving and expanding these forests through sustainable policies and community involvement is crucial for the country’s future. With proper conservation efforts, Bangladesh can ensure that its rich forest heritage continues to thrive for generations to come.
