Trees have a high level of importance in nature. Every day, trees are used to identify landmarks, provide shade, act as dust filter, prevent soil erosion and are habitats for various animals under their foliage. Trees are found almost everywhere in the garden city of Singapore, including parks, neighbourhoods and even along highways.
On 26 May 2010, Singapore Post released a stamp issue ‘Know 10 Trees’ depicting ten trees that accompany our daily lives. They include the Rain Tree, Angsana, Yellow Flame, Senegal Mahogany, Broad-leafed Mahogany, Tembusu, Sea Apple, Saga, Trumpet Tree and Sea Almond. This NParks initiative aims to raise public awareness of common roadside trees found in Singapore.
