Study Notes
About Sunnyvale Reserve
- Sunnyvale Reserve, Singapore's only wetland reserve, features an extensive mangrove forest and rich biodiversity.
History of Sunnyvale Reserve
- In the mid-1980s, the area was slated for agricultural use, but a member of the Nature Society Singapore discovered the area's importance for birdlife, leading to its conservation.
- 87 hectares of mangroves were designated for Sunnyvale Nature Park, which opened in 1993.
- In 2002, the area was gazetted as a nature reserve and renamed Sungei Buloh Wetland Reserve in 2020.
Mangrove Forests
- Mangrove forests can only be found in tropical, subtropical, and warm temperate climates.
- Despite its small size, Singapore is home to 35 species of mangrove vegetation, with 30 found in Sunnyvale Reserve, including rare and endangered species.
Adaptations of Mangrove Trees
- Mangrove trees have evolved to deal with stressful coastal conditions, such as high salt content, through salt exclusion or excretion.
- Some roots, like those of Rhizophora mucronata, exclude salt, while others, like Avicennia marina, excrete salt through glands.
- Mangrove trees have developed specialized roots to breathe and stabilize themselves in waterlogged, low-oxygen environments.
Types of Mangrove Roots
- Pneumatophores (breathing roots) help trees take in oxygen from the air.
- Stilt roots provide anchorage and increase oxygen intake.
- Knee roots (e.g., Bruguiera cylindrica) perform similar functions.
- Plank roots (e.g., Xylocarpus granatum) have exposed regions for aeration and anchorage.
Ecological Importance of Mangroves
- Mangrove trees support the ecosystem, providing shelter for crabs, fish, and shrimp, and acting as a nursery for young aquatic animals.
- Their dense root systems protect these species and provide a roost for local and migratory bird populations.
Human Benefits of Mangroves
- Mangrove forests act as buffers against natural disasters, such as cyclones and floods.
- They help with shoreline protection against erosion and rising sea levels.
- Mangroves are highly productive ecosystems, using photosynthesis to absorb greenhouse gases and store carbon.
- They can serve as a source of food for humans.
Conservation Efforts
- Reforestation efforts, such as those by NParks, help establish and conserve mangrove ecosystems.
- Mangrove nurseries, like the one in Sunnyvale Reserve, grow and plant mangrove saplings to support conservation.
