The Chek Jawa Tour

The route to Chek Jawa wetlands on the island of Pulau Ubin is a very interesting one, especially in the early mornings. Making it to Changi Village (it seems to take forever in a bus!) and after standing in the queues at the Changi Ferry Terminal, one finally gets to board an old fashioned wooden bumboat. Step into one and metropolitan Singapore is easily forgotten.

Pulau Ubin is a rural village where some of the last kampong villages of Singapore can be seen. It is also home to Chek Jawa, a preserved coral reef area with an impressive collection of marine life and associated ecosystems. Without the pressures of urban development, the island has become a popular tourist attraction where people can relax in the laid back surroundings, cycle, camp and enjoy it's rich biodiversity not too far away from the mainland. There's also a curious family of Pied Oriental Hornbills who've been granted permanent residence in the island and seem to be quite happy with the attention they get from the NParks staff and visitors. Speaking of attention seekers, there are lots of wild boars and their piglets too.

I once chanced upon an opportunity to volunteer at the Ubin-HSBC Volunteer Hub (managed by friendly NParks staff) as a guide for the Chek Jawa inter-tidal walk. I liked the place, I had a lot of time on my hands and the job was simple enough; introducing the different marine species and habitats to small groups of visitors. My only concern was public speaking because so far, I have successfully dodged about 98% of situations in life that involved any type of public speaking. It didn't require a biology background, however, mine certainly helped me during training. Training was on the job and we followed experienced guides on their tours and learnt by observation. Reading up was entirely up to us. There were only a few tours during a given month, as it was tide-dependent and most of the marine life is visible only during the inter-tidal period.

The relatively small area of Chek Jawa is prized for having six distinct ecosystems (coastal forest, rocky shore, mangroves, sea grass lagoon, sandy bank and coral rubble) lying very close to one other. This makes it an ideal area for researchers to observe and study various inhabitants that occupy these different ecosystems and their associations during varying tides. Experienced NParks staff dubbed "hunters" go early before the tours start and look for specimens on the sea grass lagoon and sandy banks. Their findings are displayed in plastic trays as temporary exhibits for the benefit and education of tour participants. This exhibit is an added bonus to see a larger collection of species that are not always visible during the walk to inexperienced eyes. The staff try to maintain a fine balance between the disturbance to the fragile environment (by human impact) and using specimens for public outreach /conservation efforts. The specimens are released when the tour groups wrap up.

Part of the challenge of being a tour guide will be to learn to adjust the facts to cater to people from different backgrounds. The audience can vary from people with a strong science background (more questions to answer!), to those from non-science backgrounds, to children (who have short attention spans) so not everyone will enjoy too much details. During one of my trainings, I was mildly annoyed to see a group of housewives ask the tour guide at each exhibit if these animals were edible and some went on to speak of their memorable experiences in trying out various seafood dishes. Not everyone sees the place with the same level of appreciation but what they all need to take back from the tour is some awareness and initiative to do what little they can to preserve these habitats.

Unfortunately, the Chek Jawa tour was put on hold for the rest of the year as the floating pontoon was due for upgrading, so my training will have to be completed when it resumes in early 2013. On a positive note, I think it'll be quite interesting to see the changes to the species populations and ecosystems when it re-opens after a prolonged period of minimal human impact by visitors to the area. Assuming the upgrading works are done carefully, that is.
