Celebrate Earth Day this April by pledging to restore nature by planting trees into our surroundings. Here are six reasons why trees are the gifts that keep giving to our City in Nature!

1. Increased well-being

 

Our trees provide many intangible gifts. Walking under the shade of trees makes us feel cooler and more relaxed, and even just looking at them can help us to recover from physical ailments! 

In medical institutions, views of trees and other greenery have been shown to help patients recover faster. On a bigger scale, trees all over our City in Nature provide many important services – they act as natural “air conditioning” to remove heat, double up as giant air filters to improve air quality, and also absorb rainfall to reduce flooding.

2. Snacks

Feeling peckish?

That pack of belinjau crackers actually comes from the seeds of the Belinjau (Gnetum gnemon), a native tree that is Critically Endangered in Singapore! The seed kernels are flattened, dried, and fried to produce the crackers with the distinctive slight bitter taste.

This cone-producing tree grows naturally in our rainforests and coastal forests, reaching up to heights of more than 20 m. Its young leaves, flowering shoots and fruits are also edible when cooked!

3. Dye

You may have seen this Critically Endangered tree blooming along our streets, but did you know that it can be used to produce dye? 

Rich in tannins, the bark of the Yellow Flame (Peltophorum pterocarpum) produces a natural yellowish-brown dye, which is used in the traditional batik industry in Java, Indonesia. Other than batik, the dye is also used to give a light yellow colour to leather during tanning.

4. Dental fillings

A Critically Endangered native tree, the Gutta Percha (Palaquium gutta) produces latex which is durable, mouldable, waterproof, and non-conductive for electricity and heat. 

This makes it extremely useful for a variety of purposes – insulating submarine and underground cables, making handles for tools and medical instruments, and of course, filling in root canals. It is used as a non-toxic dental filling for patients allergic to synthetic fillings. 

5. Medicine

Various parts of the critically endangered Tongkat Ali (Eurycoma longifolia) are said to have medicinal properties. 

While it may be most known for its use as an aphrodisiac, the roots have also been used in indigenous medicine to treat fevers and high blood pressure, as well as in poultices for ulcers and wounds. 

Other than the roots, the young leaves and bark of this native tree have also been used in general tonics and treatment for stomach pains. 

6. Dessert

Here’s another gift of trees for the foodies! The fruits of the Cheng Tng Tree (Scaphium macropodum) are what produce the jelly-like substance in the popular local dessert cheng tng. 

When soaked in water, brown, spongy fibres around the seeds absorb water and expand, forming a nutrient matrix for them to germinate (or in the case of cheng tng, eaten by us)! 

This native Endangered tree can be found growing naturally in the inland forests in our nature reserves, such as Bukit Timah Nature Reserve and Central Catchment Nature Reserve.

Interested in learning more about trees that make up our urban forest? Check out trees.sg, our online map which shows the locations of over 500,000 trees, features interesting bites of information on unique tree species, and even lets you show some love to your favourite tree by leaving it a treemail and giving it a hug!

As Singapore moves towards becoming a City in Nature, we will safeguard and extend Singapore’s natural capital island-wide. This will be the next bound of our urban planning to create a liveable Singapore for all.

Are you part of our movement to plant a million trees across Singapore over the next 10 years. The OneMillionTrees movement will take place throughout the island, including streetscapes, gardens, parks and park connectors, nature reserves and nature parks. The community is key to the success of this movement. Click here to learn how you can contribute to the movement.

Mature trees are part of the natural heritage of Singapore, serving as important green landmarks in our City in a Garden. These trees help us identify with and stay rooted to the place we call home. The Heritage Tree Scheme, started in 2001, advocates the conservation of Singapore’s mature trees. Learn more about how you can nominate a tree for this scheme.
