Have you ever wondered what would happen to the world if every human were to disappear? Perhaps you would’ve thought that since climate change is due to humans, the climate would reverse back to pre-humanity conditions, but this will take a long time (around 100,000 years actually). So what are some immediate effects, especially on our little island? Let’s take look!
Do you know that NParks conducts frequent trimming of weeds in Singapore’s reserves? This ensures that native plants are not smothered by these invasive species and maintains the ecosystem balance in our reserves. An example of an invasive species is the Dioscorea sansibarensis, or Zanzibar yam.
It is a climber which is native to Africa. What makes it so dangerous to its environment is that essentially, the entire plant is toxic. The “yam” part of the plant is often harvested for use in making hunting poison (or even poison for suicide or homicides)! As an invasive species, the Dioscorea has been recorded to overwhelm canopies with its leaves, preventing plants below its leaves from photosynthesising. Wildlife might consume parts of the plant and risk poisoning themselves too. Many areas suffering from this plant’s overgrowth have failed to recover naturally 😦
Imagine if there are no humans around to eradicate these invasive species in our reserves – many of our native species will be out-competed! If keystone plants and primary forests are affected, it might cause a detrimental impact in larger scales.
There are monkeys jumping on the bed!
Ever seen these large banners informing park-goers to refrain from feeding the monkeys?
The reason for this is to prevent these macaques, or wildlife in general, to be dependent on humans for food. Unfortunately, most macaques in Singapore are already used to getting scraps of human food and might even attack people in hopes of getting something to eat. In fact, we always warn our participants who go on our tours to keep any plastic bags they have in their bags as these macaques have associated plastic bags with food!
Without humans, there isn’t much to stop these macaques from invading the urban areas for food and territory. Thus, if everyone were to vanish, human-dependent wildlife will definitely be the first to expand into our homes in search for new habitats and food.
Of course, it is very unlikely for us to disappear in a snap. However, it is interesting to think about what the world would’ve looked like or behaved without anthropogenic interruptions. What are some situations you think might arise from the sudden disappearance of humans? Feel free to share them in the comments below!
Do you have a five-dollar bill? If you do, have you taken a close look at the design of the bill? If you take a closer look, you’ll notice a large tree in the background of the bill but have you wondered what that tree was?
Well, you might’ve guessed based on the title of this post that it is the Tembusu tree!
The Tembusu tree (Fragraea fragrans) is an evergreen tree from the family Gentianaceae that can be found in Singapore. In fact, the Tembusu tree featured in the five-dollar bill is found at Botanic Gardens, where it is deemed by NParks as a Heritage Tree.
Fragraea frangans. Its name resembles the word ‘Fragrance” doesn’t it? Well, that’s because frangans means fragrance in Latin and the Tembusu tree’s name arose from the sweet smell that its flowers give off.
The most distinctive feature about the Tembusu tree is its deeply fissured bark. When I was first introduced to the Tembusu tree, the guides even told me that the Tembusu tree looks “out of place” in Singapore because of its thick bark that resembles insulation (which is odd for a tree native to South East Asia, where temperatures are almost hot all year round).
When you come across older trees, you might notice a distinctive branching pattern in the Tembusu tree. With sufficient space, the branches of the Tembusu tree will grow out horizontally before abruptly growing vertically again, creating a sharp bend in its perpendicular branching pattern that is a signature of the Tembusu tree.
The Tembusu tree’s flowers start out white and mature into a yellow hue and give off a strong, sweet scent during the morning and evenings. Its fruits, when ripe, are round berries that are contain lots of seeds which provide food for many different species.
The wood of the Tembusu tree is hard and durable, making it commonly used for building houses, bridges, rafters and chopping boards amongst other things in the past. That being said, perhaps let’s spare the 150-year-old Tembusu tree in Botanic Gardens, shall we?
What is it: Huh? Colugo? Simi lai eh?? (translation: what on earth is that?). Well, given its elusive nature and well camouflaged body, it is not surprising that these creatures are not commonly spotted by visitors to our nature parks. Colugos are arboreal (meaning tree dwelling) gliding creatures belonging to the order dermoptera and family cynocephalidae, of which there are 2 extant and 2 extinct species . The species we have in Singapore is the Malayan Colugo or, if you are feeling particularly intellectual, you can tell your friends that you have seen a Galeopterus variegates!
How does it look like: Given that a picture paints a thousand words, let’s look at a picture of one. We can see that the Malayan colugo has fur that is mottled grey (2) or brown that is sometimes tinged with green. It is this abstract pattern that allows it to blend in so well with the canopy, making it difficult to spot.
Additionally, it has two large, forward facing eyes bestowing it with fantastic binocular vision . This could be what allows it to judge distances accurately when gliding from tree to tree. Complete with its small cupped ears, its face is certainly one that is very cute indeed! However, its party trick are its huge membranes (scientifically known as patagium) that extend from limb to limb, even in between its digits in order to give it as large a surface area as possible . Just like Batman’s cape, these membranes allow it to glide amongst the canopy, hence giving rise to its other common name, which is the flying lemur. Here’s a picture of its pretty insane looking patagium in action!

What does it eat: The diet of the Malayan Colugo consists mainly of leaves, flowers and young shoots along with some insects . It even consumes durian flowers which might not seem like good news for those durian lovers out there! However, it also performs crucial ecological functions such as seed dispersal  so it’s a pretty important member of the forest as well!
Where can you find it: The Malayan Colugo is mainly found in nature reserves such as the Central Catchment Nature Reserve (CCNR) as well as Bukit Timah Nature Reserve (BTNR). Outside of nature reserves, parks such as Bukit Batok park also harbour some populations . I have also personally seen a few at Hindhede nature park (which is next to the BTNR) as well as on trees growing next to the golf courses of the Singapore Island Country Club.
Other interesting trivia: Did you know that the Malayan Colugo can glide up to 100m  while losing only 10m in elevation? Also, having lived in trees all its life, you might think that the colugo would be an adept climber but it is far from it! It uses a clumsy hopping motion  to move up and down trees which is not exactly the most elegant method of locomotion. Lastly, the colugo rarely ever ventures to the ground, not even to defecate! Here’s a picture of it defecating from a tree!
As you can see, it has to lift its tail and wrap the membrane over its body just to take a poop. Looks really weird doesn’t it! Attached below is a fascinating video on how the colugo hops up trees and glides. Enjoy!
Well, that’s all from me today. I hope that this post has given you folks a better understanding of the colugo, which is just one of the many interesting creatures inhabiting our forests. Until next time!
I think most of us have swooned over a cute picture of a fluffy white baby seal or a small kitten with innocent round eyes. If you are like me and love animals, well good news! World Animal day is happening October 4th this year.
World Animal Day aims to raise the status of animals in order to improve welfare standards around the globe . On this day, the animal welfare movement across the globe is united to celebrate their efforts and are given an opportunity to increase awareness and education about animal welfare. Through such actions, there are hopes to create a world where animals are always recognised as sentient beings and full regard is always paid to their welfare.
October 4th is chosen for this cause in honour of St. Francis of Assisi – an animal lover and patron saint for animals, whose feast day falls on this day . 1931 was the first year it was celebrated internationally and it has been going on for 88 years since !
So… what are people doing?
World Animal Day is celebrated in a diverse manner around the world, with different focuses on conservation of biodiversity, protecting endangered animals, and supporting animal welfare.
A simple search on the World Animal Day website will lead you to a long list of events happening in each continent. There are art shows in Taiwan, releasing of native birds back into the wild in India, and a dog walk under the moonlight in South Africa .
What can I do in Singapore?
Don’t feel left out of all the amazing activities happening globally, you can do your own part in showing love to all animals here in Singapore too!
Start with a trip to Singapore Zoo, Jurong Bird Park, River Safari, Night Safari or S.E.A. aquarium. There is a plethora of knowledge to learn from these places, not to mention you get to observe and fall in love with non-native animals.
Singapore’s biodiversity is much more vibrant than most would think, besides the boars at Pulau Ubin and Long-tailed Macaques at Bukit Timah, there are numerous species of animals that can be spotted across the island. Take a walk in any of our nature reserves or parks to spot some scaly, furry, hairy or slimy locals. Of course, you can sign up for our guided walk at Macritchie Reservoir Park where we are able to help identify various species of animals too.
Take some time or money out to any of the many animal welfare groups and conservation efforts in Singapore. Head down to any of the animal shelters relocated at Sungei Tengah Road and lend a helping hand for a day or more. Garden City Fund, WWF Singapore and Wildlife Reserves Singapore are a few of the many conservation efforts we have protecting our animals and their habitats.
If you have been thinking about getting a pet as a companion, ADOPT! There is a wide range of homeless pets waiting for your tender love – dogs, cats, guinea pigs, rabbits, hamsters and even fishes! Do your research on which animals will suit you and your family’s lifestyle the best. After you are well informed of the costs and responsibilities being a pet owner entails, head on down to any of the animal shelters and choose your new family member, then shower them with love and care for the rest of their life. That being said, do not make rash decisions and only adopt if you are capable of and in an environment suitable for caring for an animal.
Spread your joy and love for animals this World Animal Day! Wish all the birds, lizards, insects, mammals or fishes you come by a happy World Animal Day, taking time to appreciate them a little more than usual.
At long last, Singapore has stepped up its conservation game! This year, on World Elephant Day (12th August), the National Parks Board (NParks) announced a ban on the domestic trade of elephant ivory, effective from 21st September, 2021 onwards . Selling ivory or ivory-made goods would be prohibited, as well as the open display of such products for sale. We will be joining other countries such as the United States, China and Taiwan in fighting against illegal ivory trafficking. In fact, our ban could turn out to be the most stringent, according to WWF . It’s great to hear that our government’s stance on this issue is far from half-hearted!
Wildlife Trafficking in Singapore
Did you know, illegal wildlife trade is actually prevalent in Singapore? Given our elevated global standing and strategic location, Singapore is a popular pitstop for illegal transactions on their way to their intended destinations . The large hauls of elephant ivory and pangolin scales seized earlier this year are proof of this .
The Why in Illegal Wildlife Trade: Elephant Parts
While it’s heartening to see Singapore’s determination in cracking down on wildlife trafficking, the problem needs to be targeted at its root – demand. Live animals and dead animal parts alike are heavily trafficked all around the world. What exactly is driving this? Well, unfounded beliefs on the properties of animal parts and the cultural symbolism of the ivory are just some factors.
There are beliefs in medicinal properties of animal parts, such as having the miraculous ability to cure various health ailments. Yet, these beliefs aren’t scientifically backed and so are merely myths. To me, this makes the whole issue more tragic. Imagine having your teeth brutally pulled out just because people think it’s a panacea to their illnesses, and your kin is slowly dying out due to this misplaced belief! In Myanmar, more elephants are being poached as demands for their body parts increase . Nothing is spared – their trunks, feet, skin, and even penis are used in traditional medicine. Their hide, for instance, is thought to cure eczema.
Moving on to the next point, ivory is highly valued, partly due to its rarity, and is carved into products ranging from religious figurines to even cutlery . Owning anything ivory says something about one’s status in some countries like China, which means that elephants are being sacrificed to indulge people who wish to flaunt their social standing and affluence… where are the ethical implications of this ? Aside from being a social symbol, some people desire ivory for spiritual fulfilment .
They perceive accessories made out of ivory such as bangles and amulets as capable of warding off bad luck and malicious supernatural beings. This is part of the reason for the pervasive ivory trade in countries such as Thailand. There, people donate to gods and receive amulets in return, which are believed to bring good fortune and protect wearers from harm . They are also readily sold in public. Amulets can be made of several types of materials, including – you guessed it – ivory ! It seems ironic to me that in a country where elephants are the national animal, people act in ways that contribute to the devastation of the very animal they revere.
More Action Needed
International trade in ivory has been prohibited since 1990, when the Convention on International Trade in Endangered Species (CITES) placed the African elephant under Appendix I – identifying the species as being threatened with extinction, and thus prohibiting trade in elephant parts (excluding exceptional circumstances) . While this has been beneficial for elephant populations, poaching is still pervasive, and domestic markets on ivory should be shut down to ensure fuller protection of elephants. Some countries have yet to outlaw the ivory trade, such as Japan . These legal markets thus undermine efforts against elephant poaching as they continue to generate demand and promote illegal ivory trafficking.
Additionally, stricter enforcement is needed in countries where domestic ivory trade has been prohibited, for the ban to be truly effective. Despite the ban on the sale of ivory in China implemented at the end of 2017, Chinese demand for ivory is still going strong . Those who are adamant in acquiring ivory products can circumvent the ban by flying to other countries to do so, such as Laos, Myanmar and Thailand, where the ivory sale is legal or the enforcement of ivory bans is lacking .
Why Conserve Elephants
Great numbers of elephants are hunted down each year for their tusks . All species of elephants – African bush, African forest and Asian – are not spared. Some people may wonder, why should we protect them? Well, some arguments for protecting biodiversity include conserving nature for its intrinsic value – the existence of elephants is in itself valuable and they are hence worth conserving; and the importance of the role of elephants in the ecosystem.
Elephants are keystone species – such species are critical for the maintenance of ecosystems . They can be considered ecosystem engineers, affecting the physical landscape or characteristics of their habitat. For example, elephants are crucial in seed dispersal – eating the seeds of plants, they end up ‘planting’ new vegetation by excreting the seeds as they move from place to place . They are capable of using their tusks to dig for water as well, providing other animals with a source of water . Without their presence, entire ecosystems are greatly affected.
Let’s have a closer look at forest elephants! Smaller in size and less prominent compared to their counterparts, their population is declining. It has been speculated that more than half the population were killed between 2002 and 2011, largely fuelled by ivory demand (and habitat destruction) . This is worrying, given their ecological importance. Forest elephants are crucial for the growth of new trees – they ingest the seeds of trees and excrete them, prompting germination (their dung serve as fertilisers!) . Furthermore, recent research has revealed that the feeding habits of forest elephants could enhance forests’ ability to act as carbon sinks . Their preference for eating young trees and “early succession” plants (the first vegetations to grow in cleared or open forest areas) has been found to promote the growth and proliferation of larger woody trees, which are capable of storing more carbon . Given the current climate crisis in which the increase in global carbon emissions is showing no signs of stopping, we really need our forests at their best carbon-storing capacity! This underlines the importance of conserving forest elephants as part of efforts against climate change.
Cracking Down on Ivory… How Far Must We Go?
Imagine needing to list the Woolly mammoth as a protected species to protect existing elephants? …What? If you found this absurd, you’re not alone, because I felt the same! This was suggested by Israel at the CITES conference this year, in which all 183 countries onboard the agreement meet to discuss details . As ridiculous as this sounds, there’s some logic underlying it. As global temperatures rise, permafrost melts (such as in Siberia) revealing mammoth tusks that have long been preserved under ice . Given how mammoth ivory trade is largely unrecorded and unregulated, there is a concern that illegal elephant ivory is being passed off as mammoth ivory (the two are not easily discernible), thus highlighting a loophole in the system . To have to label an extinct species as ‘endangered’ to better safeguard their existing kin… it truly shows how difficult it is to comprehensively deal with the illegal wildlife trade.
There you have it! I hope you learnt something new from this post. Thanks for reading!
