November falls within shorebird migration season at Sungei Buloh Wetland Reserve, bringing Singapore’s role in a much larger ecological network into focus. Across the island, Bukit Timah Nature Reserve protects another precious habitat: tropical rainforest surviving within a densely developed city. Together, Singapore’s two ASEAN Heritage Parks show how urban life and conservation can share limited space.
Two Parks, a Lasting Commitment
Sungei Buloh became Singapore’s first ASEAN Heritage Park in 2003. Bukit Timah followed on October 18, 2011—not 2019—giving regional recognition to two contrasting ecosystems: coastal wetlands and inland rainforest.
Their histories reflect sustained conservation decisions. Sungei Buloh opened as a nature park in 1993 and became a legally gazetted nature reserve in 2002. Today, it encompasses 202 hectares of mangroves, mudflats, ponds and forests. Its expanded landscape provides feeding grounds, shelter and opportunities for visitors to understand wetland ecology.
The two heritage parks sit within a broader system managed by the National Parks Board, or NParks, which oversees more than 400 parks and four nature reserves. These categories have different purposes: recreational parks complement the reserves that safeguard Singapore’s natural ecosystems.
A Singapore Stopover on a Continental Journey
Along Singapore’s northwestern coast, Sungei Buloh connects the city-state to the East Asian–Australasian Flyway. Between August and April, visitors may encounter whimbrels, common greenshanks, common redshanks and Pacific golden plovers feeding or resting in its wetlands.
For these birds, the mudflats provide essential feeding and roosting habitat during migration. For visitors, watching different bill shapes probe the mud reveals how several species can share one feeding ground.
Resident wildlife adds to the experience. Estuarine crocodiles, smooth-coated otters and monitor lizards inhabit the reserve alongside herons and kingfishers. Observing them from designated visitor areas makes conservation tangible without turning wildlife encounters into performances.
A Small Forest with Remarkable Diversity
Bukit Timah offers a different encounter: forest trails leading towards Singapore’s highest natural point, approximately 163 metres above sea level. Its significance extends well beyond the climb.
A comprehensive biodiversity survey conducted between 2014 and 2018 generated 22 scientific papers, strengthening knowledge of the reserve’s plants, animals and physical environment.
In their published synthesis, NParks specialists Lena Chan and Geoffrey Davison wrote that “there is still remarkable diversity, and new records and new species continue to accumulate.” Their findings emphasised the scientific importance of conserving even a small, isolated forest.
Building Connections for Wildlife and People
Conservation also depends on what happens beyond reserve boundaries. Eco-Link@BKE reconnects Bukit Timah and Central Catchment nature reserves across the expressway that separated them.
Animals recorded using the ecological bridge include pangolins, lesser mousedeer and common palm civets. The crossing helps wildlife move between habitats and supports genetic exchange. It is not a public canopy walkway: access is restricted because of its ecological sensitivity.
The parks’ public value therefore reaches beyond sightseeing. They support scientific research, environmental learning and encounters with nature—benefits that cannot be reduced to visitor spending alone.
Singapore’s heritage parks offer a practical lesson for growing Southeast Asian cities: protecting nature requires space, patient management and connections between habitats. From a migrating shorebird to a forest mammal crossing an expressway, their success is measured in the lives those decisions help sustain.
