The very first time I visited Chestnut Nature Park, I rushed through both the Northern and Southern trails within three hours. During this trip, the goal was to complete both trails as I had travelled a long way to get to the park. I was glad when the sign-up link for the guided walk appeared in the Whatsapp group as I really wanted a chance to slow down and find out what the park has to offer.
After doing a mini-trek up the snaking road that led to the entrance, I met up with Weijian, our guide, as well as the other participants. He started off the walk by showing us the map of the park and introducing the organisation that he represents, which is Friends of Chestnut Park. The group came about after someone/some people realised that residents who stay near the park are not even aware of its existence. It was something that surprised me greatly as the park is of substantial size and it would be hard to miss, especially as a nature lover. However, I guess people tend to miss what they don’t see and thus the group set out to educate people about the park and the biodiversity which lives within this space.
We entered a small loop in the northern part of the park and soon stumbled upon a fig tree. This particular fig tree was about 80 to 100 years old and the age was based on an estimation that was done for another fig tree of a similar size. Weijian highlighted the fact that this tree has been here since pre-war times, which serves as a reminder of how enduring biodiversity is compared to a human’s lifespan. It is also a keystone species that provides many functions such as food, shelter and the prevention of soil erosion.
I also managed to learn something new, which is that there are 3 monitor lizard species in Singapore. I’ve always thought there were just two – the Malayan water monitor (Varanus salvator) and the clouded monitor lizard (Varanus nebulous). The last one is the Dumeril’s monitor (Varanus dumerilii), which is apparently a rare and hard-to-spot species that was once deemed extinct in Singapore until an individual was sighted in 2008.

Another interesting species that we saw was the Cerulean Carpenter Bee (Xylocopa caerulea). I was only familiar with the chubby Broad-footed Carpenter Bee (Xylocopa latipes) that flits slowly from flower to flower with its unique, low-pitched buzzing. The colour of the bee was pretty mesmerising and upon further research, I found out that it is one of two species of blue-haired carpenter bees found in Singapore.

As a bonus, here’s a picture of a Malayan Colugo (Galeopterus variegatus) that we spotted later on. Needless to say, all of us were quite excited to see this cute creature hanging out on the tree.

One point that really stuck with me was actually something that Weijian mentioned at the very beginning. He said that the Friends of Chestnut Nature Park is a community effort for residents, by residents. I think it’s really meaningful to involve and engage the community in such efforts as it helps to inculcate a sense of ownership and belonging towards the park among the residents. In addition, it does feel like it would be a more sustainable initiative as the members are typically residents who stay nearby and it would be logistically easier for them to consistently check up on the park and get together to organise events/guided walks.
This was a great way to end off the field trip component of the BFF program and I have thoroughly enjoyed each and every one of them. Not only were they great stress-relievers, but they also imparted new knowledge and insights about the history and biodiversity of the parks I visited. It was definitely a good decision to join and complete BFF 2022 🙂
