Animal ofthe Month
Lutrogale perspicillata (Geoffroy, 1826)
Otters can be spotted quite regularly in groups of two to more than 10 in our mangroves, mudflats, and other coastal areas. Cute as they may be, otters smell quite pungent, particularly near where they leave their spraints (otter defecation) to mark their territory on land. If you spot otters, do not touch, chase, or corner them, as this may frighten them. Instead, watch them from afar.)

Cicada Tree!
It is believed that the Cicada Tree (Ploiarium alternifolium) got its name after local folks saw cicadas perched on this shrub. Native to Singapore, this plant can be found in secondary forests and near water bodies such as freshwater swamps and reservoirs. When the wind blows, its glossy red-edge leaves dance and move like fingers! It has light pink-tipped white flowers which attract bees, butterflies and birds. The fruit splits open like an umbrella when ripe and releases numerous seeds.

Colour-changing magic
Commonly known as Butterfly Pea plant, the flowers of Clitoria ternatea is one of the key ingredient for the colour changing drink which is taking over the world by storm. Dried flowers are boiled to produce a blue solution, and it changes to purple when lemon juice is added! In traditional Peranakan culture, the blue pigment is also used for popular dessert like Kueh Salat. Butterfly Pea plant is widely cultivated in home gardens and the roots can improve soil quality by fixing nitrogen. Click on the button to learn more.

Happiness Tree
The Happiness Tree (Garcinia subelliptica) is a common sight in the rural landscapes of Okinawa, Japan. The tree’s hard, dense wood can withstand fire and physical stresses from strong winds and are often planted in gardens to provide a barrier for houses from fire and destructive typhoons. The tree’s evergreen, thick glossy leaves also provide shade from the relentless sun. In that sense, the Happiness Tree brings joy by protecting families from natural disasters like fires and typhoons supporting a happy family life

Traveller’s Palm
Did you know that the Traveller’s Palm (Ravenala madagascariensis) is not a true palm? It belongs to the Strelitziaceae family and it is a close relative to the Bird of Paradise plant (Strelitzia reginae). Native to Madagascar, the Traveller’s Palm is popular in tropical landscape because of its enormous leaves which are arranged in a fan shape. It produces big, erect inflorescence like that of Heliconias. However, it seldom blooms in Singapore due to the wet weather. Its fruit are brown capsules, enclosing numerous seeds covered with bright blue arils.

View AllPlant diversity in Bukit Timah Nature Reserve
Over the years, biodiversity surveys have been done in Bukit Timah Nature Reserve (BTNR) to document Singapore’s green treasures. 1250 plant species have since been recorded in BTNR (Ho, B.C. et al. 2019) in Singapore’s first Nature Reserve and researchers continue to find species new to science, species previously unknown in Singapore, and species thought to be extinct.

05 Sep, 2019The science behind companion planting
Gardeners have long known that some plants naturally repel insect pests and placing them near susceptible plants helps to protect them, also known as companion planting. Scientists examined one such pairing and found that French marigolds help protect tomato plants from glasshouse whiteflies. They determined that the marigolds emit a chemical called limonene in the air which repels but does not kill whiteflies.
22 Jul, 2019Trees Keep Cities Cool
The cooling effect of a small forest in the city has the profound effect of cooling the environment. Summer daytime temperatures can be lowered by 3.4 degrees Celsius. Hard city surfaces take in heat from the sun in the day and gradually give off the heat in the night. Trees however not only shade those surfaces, they also release water into the air through transpiration, cooling the surroundings. The study showed that for maximum cooling benefit, the tree canopy cover must be greater than 40 percent of an area. This information is useful for city planners to develop more livable neighbourhoods.
