Singapore's longest green corridor was unveiled on Sunday morning by the National Parks Board (NParks) and the South West Community Development Council (CDC).
When completed by the end of 2014, Tengah Nature Way will be lined with trees and shrubs to help the movement of small animals like birds and butterflies.
The 13-km stretch will connect the Bukit Timah and Central Catchment Nature Reserves in central Singapore, to the Western Catchment area where the SAFTI live-firing area is located.
It will comprise community gardens and greenery planted along roads in residential areas to bring biodiversity closer to the neighbourhood.
The green corridor will also create a route for small animals to travel between the two wooded areas in central and western Singapore.
Tengah Nature Way will be the longest of seven nature ways in Singapore.
The others are located in Punggol, Tanglin, Admiralty, Yishun, Tampines and Kheam Hock.
Work has already started on the longest green belt with plants lining more than half the 13-km stretch.
These were planted by NParks and about 21 community groups, corporate organisations, schools and South West District neighbourhoods.
They include Hillgrove Secondary School, NatSteel and Almukminin Mosque.
"It is wonderful to see so many people stepping forward to green up Tengah Nature Way and their neighbourhoods," said outgoing chief executive of NParks Poon Hong Yuen.
"Through this initiative, we hope more people will develop a deeper appreciation for Singapore's rich biodiversity and join us to take ownership of our City in a Garden."
