Bukit Timah Hill, an Oasis for Local Biodiversity (2/7)

Even if you have not scaled this 164-metre hill, chances are you would have driven by it along the Bukit Timah Expressway or Pan Island Expressway. Bukit Timah Hill is made of igneous granite, a rock that was so sufficiently present in Singapore that it was exploited to construct roads during the early days. Bukit Timah granite has been around since the Middle to Late Triassic period, that’s about 245 million years ago when dinosaurs roamed the Earth! Today, Bukit Timah Hill sits in a protected nature reserve and is home to many of Singapore’s native flora and fauna, including the endemic commelinid, Hanguana neglecta and two species of freshwater crabs.
