The Story of Saving Macritchie So Far

Recently, I’ve seen Facebook posts about the Cross Island Line on my newsfeed posted by those outside of my usual echo chamber of environmentally-conscious, nature-loving friends. The Cross Island Line debacle has finally surfaced into mainstream public consciousness. People are talking about the impacts of building an MRT line through a forest our city in a garden. This comes almost two years after it was first announced as part of the 2013 Population White Paper, which led to lively but unsustained conversations about it. A petition started by a concerned individual began to garner signatures. It was discussed at the Singapore Future Sustainability Symposium. Nature groups conducting walks in Macritchie Forest drew attention to the matter by incorporating it in their guide notes. An alternate route was proposed by Nature Society Singapore in a position paper submitted to the government.

What’s changed now? The debate has grown to include interwoven perspectives about our (under)valued biodiversity and natural heritage, treasures for the next generation, benefits of connectivity, difficult questions about development versus preservation, fissured environmental laws, and lessons in stakeholder engagement.

This is in response to the newly-released environmental impact assessment (EIA) report solely on the environmental baseline and soil investigation works that are required for future construction of the line. Notably, this is the first phase of the EIA, upstream of a future study that will assess the construction and operation of the underground train tunnels.

This EIA report has over 1,000 pages and 7 chapters, and is available for viewing at LTA by appointment only. There are no digital copies, making details about the EIA vaguely translated at best – a defensive move given the lack of legal requirement for EIAs to even be produced, much less open to public scrutiny. Information here on the EIA have been personally noted, and I take responsibility for any inaccuracies. [Update 19/2/2016: The LTA has now released the EIA online in full for public viewing here, a move made after the lack of transparency was raised in a letter to the Straits Times.]

The time is ripe for a decision by LTA to select one of two viable options proposed in the report:

Option 1 (Green): 1.8km route cuts across Macritchie/CCNR from the Singapore Island Cross Country Club to the Pan Island Expressway (PIE)

Option 2 (Blue): 9km route skirts around it Macritchie/CCNR from the southeast of SICC, beneath to Lornie Road and parallel to the PIE

The engineering feasibility of the Cross Island Line likely depends on soil investigation works to map out the geology of the area for both options. For Option 1, the train tunnel ought to go through Bukit Timah Granite for structural stability, and this is the reason why 16 boreholes (instead of 72 originally planned) will be drilled 50-70m underground for analysis.

Importantly, the EIA studied the impacts of soil investigation works on surface water quality (groundwater quality was studied without intrusive testing), ambient noise, vibration, ambient air quality, and ecology and biodiversity.

Option 1 presents particular concerns. Even though a rather robust Environmental Mitigation and Monitoring Programme has been recommended to reduce almost all impacts to acceptable levels of minor to moderate or negligible, there still remains the possibility of accidental events . Uncontrolled site runoff, spills from construction fluids, roadkill and damage to vegetation from vehicle movement could all occur – the likelihood of which could fluctuate based on how well measures are observed.

The language of the EIA has diffused into media reports, with words like impact receiving attention. Translated from the Impact Significance Matrix, impact is a composite of sensitivity/vulnerability/importance of receptor/response and magnitude of impact (with factors of extent, duration, scale and frequency). Typically, we want to minimise impact to minor or negligible, especially if they are in highly sensitive areas such as areas directly within the reserve. The type and likelihood of impact is also important. The phrase “as low as reasonably practicable”, stylised as ALARP, is also mentioned as a caveat to the limits of engineering ingenuity, standards, protocols and emergency action plans to reduce these impacts.

The construction of a Cross Island Line is one that has particular pressure points which lie outside the scope of the EIA report:

1. Macritchie / CCNR is the largest nature reserve in Singapore. While it is gazetted by law, it has not been accorded blanket protection.
2. The biodiversity and habitats found in Macritchie are unparalleled and scarce. Flora and fauna species are already endangered and cannot be found elsewhere, while the high urban cover of Singapore has reduced primary and secondary forests to these few remaining patches in our nature reserves.
3. The costs of picking Option 2, the route that skirts around the reserve, have not been clarified by LTA yet.

A concerted move by environmental groups to push for a “zero-impact policy as a starting point to avoid long-lasting impacts on the environment” is making itself visible and vocal on social media platforms, garnering support from the masses with each share and like. The Love Our Macritchie Forest movement, fronted by the Toddycats, the BES Drongos, and the Herpetological Society of Singapore, is putting pedal to the metal – or in this case, boots on the ground.

March for Macritchie is a series of guided tours in March initiated by Love Our Macritchie Forest that the general public can sign up for – and decide for themselves the values that they place on biodiversity intrinsically, as educational tools, or for wonder to be experienced by themselves or their children.

“You can’t miss what you don’t know.”

This slogan captures precisely the motivations for me to be part of the Love Macritchie movement. You can’t miss what you don’t know about the local biodiversity housed in our forests – a part of our terrestrial environment that still remains audaciously non-urbanised. And you won’t miss it until it’s gone. (Pictured here are some of the animals found in Macritchie.)

Such is the impassioned, heartfelt plea from environmentalists such as myself to not only minimise the impact of the Cross Island Line, but to reduce the impact to zero. This is not unachievable, given the fact that there is after all, literally another option on the table present as a thinner (and hence detailing fewer impacts) bound report: the alternate Lornie Road route, Option 2.

EIA (Phase 1) of CRL announced: where do we go from here?

On 5th February 2016, Phase 1 of the Environmental Impact Assessment (EIA) was announced by the Land Transport Authority (LTA). The report concluded that:

1. Site investigation works will have moderate impact on the environment, if mitigating measures are taken.
2. As such, soil testing will still go ahead.

Soil testing works involves deep drilling into the ground of the forest, and is done to determine the soil composition of the potential construction site of the Cross Island Line (CRL), as part of risk assessment protocol.

While we, the BES Drongos and other concerned individuals from the Love Our MacRitchie Forest movement have been hoping for the forest to be left undisturbed, the fact remains that drilling will still go ahead.

However, as much as we are disappointed with the EIA outcome, our voices have not been ignored. Following concerns from various nature groups, LTA has decided to:

• Reduce the number of boreholes from 72 to 16;
• Confine drilling to public trails and non-vegetative areas; and
• Employ more non-intrusive (no physical alteration) methods in soil investigation.

Furthermore, an alternative route first suggested by the Nature Society is currently being considered as a viable second option. The suggested route will skirt around the nature reserve instead of cutting directly through it, which means less direct disturbance to the forest ecosystem.

So what can we do? Where do we go from here?

While we can’t reverse the decision made by LTA, if you are concerned about this issue, here’s what you can do to help:

1. The EIA will be open for public viewing for the next 4 weeks; book an appointment to go down and view it.
2. Help spread the news and raise awareness! Tell your friends, your family or anyone who you know cares about this. If lots of people go down to view the EIA, it will show LTA how much the public cares.
3. Voice your support for the alternative route. The alternative route is now our best (and last) bet to reduce significant impacts on the forest.

You can contact LTA [Ms Michelle Chan (email LTA_CRL_CCNR_EIA@lta.gov.sg or call 6295 7437)] to view the EIA and give your feedback. Please note that you can view it by appointment ONLY, at Land Transport Authority, 1 Hampshire Road (Blk 11 Level 4, Room 2), Singapore 219428

In addition, to show your support for the alternative route, you can sign the petition here: http://www.tinyurl.com/lta-crl

The Central Catchment Nature Reserve (CCNR) is home to 400 species of trees, 200 species of birds, 400 species of insects and 150 species of mammals and amphibians. If you’d like to learn more about the biodiversity found in the CCNR, please do sign up for our walks!

Toddycats and Drongos Unite!

This week the Drongos had some special guests with us, the Toddycats! The Toddycats are nature and environment volunteers with the upcoming Lee Kong Chian Natural History Museum, and they run another trail in MacRitchie, called the Venus Loop that is located further down Upper Thompson. The Toddycats also manage the Love Our MacRitchie Forest movement, which was launched in response to the proposed Cross Island Line (CRL) that would cut through MacRitchie. The Toddycats hope to educate the public through their walks about the fragile ecosystem and stunning biodiversity we have here through their trails, and the Drongos are hoping to follow in their footsteps. So in a way, the Toddycats are our mentors, and we certainly learnt a lot from them on this trail.

This trail was also pretty special because it was the first time our volunteers were presenting to non-Drongos, and we are proud to say that they are shaping up to be promising guides!

However, we all certainly still had a lot to learn, as the Toddycats amazed us with their uncanny ability to spot all sorts of biodiversity along the trail. So for today’s post, there are a whole lot more animals, and we hope that with more experience we can someday be as sharp as the Toddycats in spotting such amazing creatures!

This Ornate Coraltail (Ceriagrion cerinorubellum) was flitting around near the boardwalk. The Coraltail is a damselfly, which is not the same as a dragonfly, even though they look very similar. Both dragonflies and damselflies are from the order Odonata but are generally classified into two different suborders, with dragonflies under Anisotera and damselflies under Zygoptera. The most obvious difference between dragonflies and damselflies is that damselflies have a long, slender body as compared to dragonflies, which have shorter, stockier bodies.

We were very lucky for this trail as we spotted both a Malayan Blue Coral Snake (Calliophis bivirgatus) and Wagler’s Pit Viper (Tropidolaemus wagleri )(photo below), highly venomous snakes that we had not seen since our first recce of the trail. A fun (and rather frightening) fact that we learnt from the Toddycats was that the Malayan Blue Coral Snake is also known as the Hundred Paces Snake, because its venom is so powerful that a person can only make it about a hundred paces after being bitten before they die. Ouch.

It seems that the snakes like to bask near the boardwalk because the vegetation is not as dense there and thus has more sunlight. Because venom takes a while to make, it a good thing to remember that snakes generally will not attack non-prey animals (for example, us) unless they are highly threatened or cornered, so if you ever see a snake, give it some room and back away slowly so as to not startle it. Always ensure that the snake has an escape route, and you should be fine!

Another interesting reptile we saw today was a Clouded Monitor Lizard (Varanus nebulosus), named as such because it has beautiful yellow cloud-like markings on its back. Monitor lizards are closely related to Komodo Dragons (the largest lizards in the world which grow up to 3 meters long), but thankfully all the Monitor Lizard species in Singapore are unable to grow that big.

This Common Sailor butterfly (Neptis hylas papaja) was resting on some Resam ferns (Dicranoptris linearis). Both the Common Sailor and Resam like the sun, and both are common species found on nature reserve fringes.

Speaking of butterflies, we found this fantastical caterpillar (Eudocima smaragdipicta) creature so strange that it really seems otherworldly. Other than the weird Pokémon ball-looking patterns found on its body, the oddly shaped “head” at the end of the caterpillar facing up in this photo is actually its tail! The caterpillar uses its false head to give the impression of a rearing snake as it raises its behind, serving as a defense against birds and other hungry predators.

While we are on the topic of fake snakes, we also found the flower of the Rattan Plant (above) and the resulting fruit (below). The scaly fruit develops in between the “cups” of the long, segmented flower, and the cups only fall off after the fruit is ripe, exposing the fruit bunches.

As most of us know, the main stem of the plant is often used to make furniture and other products (like canes), but did you also know that the fruit produces a red resin known as “dragon’s blood” and is often used to dye violins?

Well, that is about it for this trail! We would like to give special thanks to the Toddycats Chloe Tan, David Tan, Yi Yong, Sean Yap and Amanda Lek for taking the time to come down to our trail with us! We hope that as we develop our own stories and gain experience as guides that we will one day make you guys proud. (:
