For the primary time final yr, extra useless than residing pangolins had been shuttled to the Wildlife Healthcare & Analysis Centre at Mandai, Singapore’s zoo complicated, the organisation has confirmed.
Some 23 Sunda pangolins hit by automobiles had been ferried to the centre by conservation teams in 2022, based on newest statistics from wildlife rescue centre Acres. A lot of them didn’t survive.
It is a enormous leap from official numbers from 2016 to 2021, when a median of three to 9 pangolin roadkills had been reported a yr. Since 2021, the common has crept as much as 20 circumstances a yr. 2023 was a document for pangolins hit by automobiles.
To this point this yr, the variety of pangolin casualties has been low. The primary roadkill of the yr was on Sunday, World Wildlife Day, in a residential space close to fragmented forest patches, Eco-Enterprise understands.
Although absolutely the variety of casualties appear small, Singapore’s Nationwide Parks Board (NParks) estimated in 2016 that there are about 100 wild pangolins left. The conservation company has since stopped publishing inhabitants estimates, with NParks reportedly saying that it is because the numbers have been onerous to pin down.
The tropical city-state has claimed to be one thing of a refuge for this critically endangered mammal. Whereas poaching of untamed pangolins, the world’s most trafficked mammal, is rampant elsewhere in Southeast Asia, the creature has been comparatively secure from the wildlife commerce in Singapore.
“
Singapore ought to cope with the foundation explanation for pangolin endangerment – deforestation – as an alternative of simply treating the signs.

Not completely, although. In January, an air drive common was caught making an attempt to promote a pregnant pangolin for S$1,400 (US$1,050) on Telegram. The animal, which had been fed fruit and greens as an alternative of its pure weight loss plan of ants, was recovered in a sting operation by NParks.
In response to Eco-Enterprise’s queries on the most recent statistics, NParks mentioned that the principle threats to pangolins in Singapore are habitat loss and alteration, in addition to highway site visitors accidents. “This contrasts with the most important threats that this species faces regionally, which embrace poaching and unlawful commerce,” mentioned NParks’ group director of conservation, Lim Liang Jim.
Nparks additionally mentioned that the spike in pangolin deaths could possibly be as a consequence of “better public consciousness about pangolins and wildlife, and easy methods to go about reporting such circumstances”.
In Singapore, pangolins have been spared the extent of poaching they’ve suffered elsewhere – one pangolin is poached from the wild each three minutes globally, primarily for its scales to be used in conventional medication, based on conservation group WWF. In Singapore’s case, the largest menace is urbanisation.
Native conservationist Dr Ho Hua Chew advised Eco-Enterprise {that a} “obtrusive issue” contributing to the decline of pangolins in Singapore is the lack of remaining secondary forest as a consequence of growth for housing, industrial estates, transport amenities and army initiatives.
“Roadkills are inevitable as roads have multiplied and vehicular site visitors has change into extra intense and the inexperienced panorama has change into extra fragmented and concretised,” he mentioned.
Secondary forests and survival
Dr Ho cited areas reminiscent of Mandai Lake Highway, Kranji Woodland, Decrease Seletar, Bukit Gombak, Bukit Mandai and Dover as the place growth has eliminated pangolin habitat and meals sources. Pangolin roadkill sizzling spots embrace Mandai Highway, the place there was deforestation to increase Singapore’s zoo complicated, and Bukit Timah Expressway, a highway that dissects two nature reserves.
Among the many most up-to-date patches of secondary forest to go is in Tengah, the place a “forest city” is being constructed. Tengah forest, about half of which has been razed since development started in 2017, was a key connection level to allow pangolins to maneuver between the Western Catchment forest and the Central Catchment Nature Reserve, noticed Dr Ho.
In contrast to Singapore’s thriving populations of otters and civets, forest-dependent Sunda pangolins don’t fare properly in city environments, and are sometimes rescued by animal welfare teams with accidents from making an attempt to navigate razor-wired fences and different obstacles.
In August 2023, a pangolin was discovered within the extremely urbanised housing property of Toa Payoh. It was limping. It’s possible that the pangolin wandered out of Bukit Brown forest or the remnant of Toa Payoh grave hill forest, as a consequence of disturbances brought on by the development of the North-South Hall, a highway that may join Singapore’s northern area to the town, mentioned Jimmy Tan San Tek, a neighborhood conservationist.
NParks has been working to preserve Singapore’s pangolin inhabitants by making a community of nature parks that encompass Singapore’s nature reserves to function ecological buffer zones. The company can also be making an attempt to enhance connectivity for wildlife by establishing nature corridors that act as “ecological stepping stones”.
Nonetheless, Tan mentioned most of Singapore’s conservation efforts have targeted on nature reserves and buffer parks, not on the island’s secondary forests, that are residence to different endangered species, such because the straw-headed bulbul. Secondary forests reminiscent of Clementi forest, Bukit Brown forest, and the remaining half of Tengah forest, are at risk of being destroyed or fragmented additional, since they’re zoned for growth, he mentioned.
Secondary forests account for about one-fifth of Singapore’s land space and are susceptible to growth, as a result of they don’t seem to be protected by legislation. In accordance with a paper printed final yr, Singapore may convert 7,331 hectares of secondary forest – an space 1.2 occasions bigger than that of all of the parks and nature reserves mixed – over the subsequent 10 to fifteen years, based on the nation’s city growth plan.
Tan mentioned that in some areas the nature corridors are too skinny to allow pangolins to maneuver comfortably across the island. As an example, the 100 metre-wide nature hall at Tengah is “grossly inadequate” to make sure that pangolins can burrow safely, since they are going to discover themselves in uncomfortably shut promixity to the housing growth, Tan has argued.
Additional inhabitants declines could be anticipated in the event that they proceed to lose forest habitats and ecological connectivity, and expertise inbreeding as populations change into more and more remoted, Tan mentioned.
Dr Ho famous that whereas efforts to create wildlife corridors in Singapore are laudable, such efforts are pointless if the remaining patches of secondary forest are drastically curtailed or worn out. “There may be an pressing have to be constant in our conservation work – for the sake of the long-term survival of not solely the Sunda Pangolin however all of our remaining wildlife,” he mentioned.
“The necessity to protect extra of the remaining forests outdoors the character reserves needs to be the overarching focus of our conservation efforts,” Ho mentioned.
Singapore, which manufacturers itself as a “metropolis in nature”, dedicated to finish deforestation by 2030 when it signed a pledge with 130 different nations on the COP26 local weather talks in 2021.
“By the point Singapore heeds the no-deforestation by 2030 settlement, there might not be a lot forest left for the pangolins to proceed surviving within the wild,” Tan mentioned.
Singapore ought to prioritise recycling beforehand developed lands as an alternative of sacrificing the forests for housing and different developments, he advised.
