by Ho Hua Chew, Anuj Jain & Alan Owyong

(ISBN: 978-981-14-3051-0)

Recommended reading:

This timely conservation book records with photos from above of the last remaining precious forest patches along the longest green corridor (24km) in Singapore, once a historic main Railway line to Peninsular Malaysia and branch line to Jurong.

See the Maps and discover the ecological and biodiversity importance of this long and narrow lifeline for local wildlife and communities.

Green gems like the little known river, Sungei Pang Sua, and its adjacent charming Woodland is home to many species of birds. Rare flora such as formerly presumed nationally extinct plants and rare fauna, such as the endangered Grey-headed Fish Eagle (Ichthyophaga ichthyaetus) and Violet Cuckoo (Chrysococcyx xanthorhynchus) have been recorded at Clementi Forest.

Find out why these last wilderness pockets should be conserved. The authors advocate a robust plan for the conservation and enhancement of the ecological connectivity of the Rail Corridor which is a priceless natural and historical-cultural heritage.

Wildlife Watching Walks for November 2019

Forest village trek at Thomson Nature Park

Date: SATURDAY 23 NOVEMBER 2019
Time: 9.00am to 11.30am
Cost: $13 per pax (adult or kid). Free for participants’ kids aged 6 years and below.
Location: Thomson Nature Park

Please note: This is an easy walk that goes on an uneven dirt path with sloping ground at certain spots, but do note that the return walking distance is between 4 to 5 km. If young kids are coming along, be prepared to carry them.

Walk Brief:

We explore the trails running through this newly opened nature park set in a former Hainanese village. The forest has taken over the remains of the village, but some of its ruins still exist, such as the spiral staircase of the house of the Fox family who were Eurasians who had lived there. Signage along the trails explain the nostalgic ‘kampong’ way of life. Fruit trees from past orchards persist, with rambutan, durian and jackfruit now enjoyed by the wildlife living there.

This park is a key conservation site for the critically endangered Banded Leaf Monkey, Singapore’s only other species of monkey. The Malayan Pangolin and Straw-headed Bulbul are two other globally endangered species who call this lush forest patch their home. And the forest streams here are crucial freshwater habitats for a diversity of damsel and dragonflies.

Hornbills and Hogs on Pulau Ubin

Date: SATURDAY 23 NOVEMBER 2019
Time: 5.00pm to 7.30pm
Cost: $13 per pax (adult or kid). Free for participants’ kids aged 6 years and below.
Location: Pulau Ubin

Walk brief:

We return to the lovely island of Pulau Ubin, this time to look for its famous resident hornbills and wild pigs. The Oriental Pied Hornbill is the only hornbill species still existing in the wilds of Singapore. Its other larger cousins, the Rhinoceros and Helmeted hornbills have both long gone extinct, as Singapore developed and its human population grew and spread. Hornbills have an incredible lifestyle. The female will imprison herself in a tree-hole nest for several months to take care of her eggs and chicks, with the male bringing food to them. As there are not many tall old trees with suitable holes, some nest boxes have been set up for them on Ubin.

Oriental Pied Hornbills live in large, loud family groups, so we’ll hear them before we’ll see them. The Wild Pig is the other iconic wildlife of Ubin. In the past, ‘wild boar’ meat was served at the food stalls on Ubin. It is now against the law to capture, kill or eat them. On Ubin, they roam the forests in search of fallen durian and rambutans. Many Ubin regulars still have fond memories of Priscilla, the piggy mascot at Chek Jawa who was always there during low tide on the mud flats. Our late afternoon to evening walk is timed to the hornbills about to go to bed while the pigs are just waking up from their afternoon siesta.

Please note: This is an easy walk that goes on the main roads and on uneven dirt trails. The return walking distance is about 3km.

Farewell, Subaraj

Subaraj Rajathurai
1963 – 2019

I was in college on my first journey into nature at Bukit Timah Nature Reserve. And even though this was a strange environment that I wasn’t particularly used to, it felt like coming home. I never turned back since.

A lot of people do give up their dreams, but are they happy? Do they look back in regret? I don’t. I’m a firm believer that if you have a passion, a dream, make it work. Because that’s who you are supposed to be.

Subaraj Rajathurai

Singapore has lost an amazing son, superb naturalist, master nature educator and passionate conservationist.

Subaraj Rajathurai was a walking encyclopedia and fountain of knowledge on biodiversity. He cared deeply for nature, fought for Mother Earth and gave unselfishly to us all.

A pioneer in nature conservation, Subaraj spoke fearlessly to protect our last wilderness — even when it was unpopular to do so. He continued being a voice for the voiceless, even during the last days of his life.

Subaraj inspired generations of students and budding conservationists. All will never forget the lessons he taught about the importance and beauty of the amazing natural world we live in.

All of us at Cicada Tree Eco-Place are devastated by the loss of a wise, caring and courageous friend. We will always miss his hearty laughter and huge personality.

Subaraj, your demise is a huge loss that can never be replaced. We owe you a debt of gratitude and will always strive to carry on your torch and legacy.

May you rest in peace with the songs of birds in the eternal jungle.


Read about Subaraj’s lifetime of contributions to nature conservation, as reported in The Straits Times, The New Paper and TODAY newspapers. Watch this poignant Singapore Tourism Board Passion Made Possible feature celebrating his life:

Subaraj Rajathurai – wildlife consultant and nature guide

In memory of Subaraj Rajathurai – self-taught naturalist, wildlife expert and a Singaporean whose passion inspired us all. He will be missed.
