Sights and sounds of Gillman’s rich biodiversity
In this video, we also see the site of a recent massive slope failure in Telok Blangah hill park, which serves as a cautionary tale for Gillman Forest, which grows on steep hill slopes in some parts of the area.
This video features the song of the hill mynah heard around the northern fringe of Gillman Forest, where the elevated walkway links Alexandra Arch to Telok Blangah hill park.
Since the hill mynah is one of the indicator species identified by NParks’ ecological profiling exercise as part of the science-based approach to urban development and nature conservation, Gillman Forest should be protected as a vital habitat and ecological corridor for wildlife (including the critically endangered straw-headed bulbuls too).
“There are six indicator species that the connectivity map is based on: three mammals - the Annandale’s rat, Sunda pangolin and treeshrew - and three birds, the hill myna, blue-winged leafbird and white-rumped shama.
NParks said these species were selected as they are sensitive forest dwellers that prior studies have shown can be coaxed to use wildlife corridors, provided a suitable habitat is created for them there.
Their movement pathways would provide a conservative estimate for the routes that other animals will take, said Dr Tan Puay Yok, NParks’ chief science and technology officer, who was part of the team that first explored the use of the methodology.”
