Diversity of Tree Species in Singapore

Singapore is home to a diverse range of tree species, both native and exotic. The city-state has made significant efforts to conserve its natural environment and biodiversity, including its trees.
Native Trees and Biodiversity
Singapore’s native trees play a crucial role in maintaining the city-state’s biodiversity. Some of the most common native tree species include the Rain Tree, Angsana, and Pink Mempat. These trees provide habitats and food sources for a variety of animals, including birds and insects.
Conservation efforts have been made to protect these native trees, with initiatives such as the Heritage Tree Scheme managed by the National Parks Board. This scheme aims to conserve Singapore’s mature trees, including native species, and recognize their significance in the city-state’s landscape.
Exotic and Urban Trees
In addition to its native trees, Singapore also boasts a variety of exotic and urban trees. These trees have been introduced to the city-state over the years, and many have become iconic symbols of Singapore’s urban landscape.
One such tree is the Tembusu, a large evergreen tree with a dense canopy that provides shade and shelter. Another popular urban tree is the Pterocarpus Indicus, also known as the Angsana, which has bright yellow flowers and is commonly planted along roadsides and in parks.
The Samanea Saman, also known as the Rain Tree, is another exotic tree species that has become a familiar sight in Singapore. This tree has a wide canopy and provides ample shade, making it a popular choice for parks and outdoor spaces.
Overall, Singapore’s diverse range of tree species, both native and exotic, plays an important role in maintaining the city-state’s environment and biodiversity. Efforts to conserve and protect these trees are crucial in ensuring their continued presence in Singapore’s landscape.
Conservation and Heritage

Heritage Trees and the Heritage Tree Scheme
In Singapore, trees play a vital role in the city’s landscape and identity. The National Parks Board (NParks) has identified and recognised individual majestic trees in the city that are of botanical, social, historical, cultural, or aesthetic value. These trees are known as Heritage Trees and are conserved under the Heritage Tree Scheme.
To be considered a Heritage Tree, a tree must have a girth size of at least 5m or meet one of the other criteria mentioned above. The Heritage Tree Scheme is an advocacy programme that encourages the conservation of Singapore’s mature trees. By supporting the Heritage Tree Scheme, you can help to identify, recognise, and conserve these trees.
The Singapore Botanic Gardens‘ Tembusu tree is an example of a Heritage Tree. This tree is older than the 155-year-old Gardens and is now protected as a Heritage Tree. Fort Canning Park is another location where you can find Heritage Trees.
Greening Efforts and Community Involvement
Singapore is known as the Garden City for a reason. The city’s greening efforts are a testament to its commitment to sustainability and environmental conservation. NParks is responsible for the management of Singapore’s parks and green spaces, including the Sungei Buloh Wetland Reserve, a UNESCO World Heritage Site.
Community involvement is a crucial aspect of Singapore’s greening efforts. You can participate in tree-planting activities and other community events organised by NParks. By doing so, you can contribute to the city’s efforts to create a sustainable and green environment.
In conclusion, Singapore’s trees are an integral part of the city’s identity and landscape. The Heritage Tree Scheme and greening efforts are essential in ensuring that these trees are conserved and protected for future generations to enjoy.
