Mandai mangroves, Western Johor Straits, Singapore
JEWEL IN JEOPARDY

By Joseph Lai, 2nd September 2003

Sungei Buloh Wetland Reserve, located in a district fondly referred to as Kranji by many, sits pretty along the scenic waterway of Western Johor Straits.

Though much change had been effected by our nation's underlying need for water, the damming of several river systems, namely, Kranji, Sarimbun, Poyan and Tengah, did not seem to eliminate the 'naturalness' one still feels and sees especially from the vantage point of a boat ride along this strait. In a word, it is a visual feast &endash; one which is fundamentally enhanced by the remaining coastal vegetations that had survived such change and the diversity of coastal birds that grace the sky above.

At the heart of this naturalness, Sungei Buloh Wetland Reserve sits like a crown jewel. 'Gem' was how Senior Minister Lee Kuan Yew described Sungei Buloh in his congratulatory note written in the Visitor Book during a recent visit. He is not alone in this sentiment. Of the 5000 Singaporeans 'from all walks of life' solicited for feedbacks to URA's Concept Plan 2001, 'they all felt there was a need to protect nature areas and Sungei Buloh was mentioned at the time' - Mr. Wong Tuan Wah, Director of Park Management, National Parks Board (ST, Nov 12, 2001).

Indeed, this gem is highly valued and a great price has been paid for it.

'The land was actually zoned for an agro-technology park. It would have been a profitable economic venture. Instead, we decided to turn it over to the birds', said Prime Minister Goh Chok Tong when he opened Sungei Buloh as Singapore's first wetland nature park in 1993. 'Considering that we have a very high population density of about 4,400 persons per sq km, this is a big commitment to nature conservation', he said (ST, Dec 7, 1993). Come December 2003, another 10 years of 'opportunity cost' or investment would have been added to this value.

However, one should not forget the crown for the jewel.

The gem that Sungei Buloh is has in the millennia been set securely in the 'silver' and 'gold' of adjacent ecosystems. All are linked as close ecological partners, and any detrimental changes to one may affect the others irreversibly. Recent exclusion of Sungei Mandai from URA's draft plan poses questions about this vulnerability. If ecological links are 'broken', our crown jewel and all our investment may be lost at sea forever.

Prof. Murphy D. H., a well-loved lecturer whose decades of tutorage at the National University of Singapore had moulded several generations of biologists, had this ecological link firmly in mind when he wrote his paper 'Birds, Mangroves and Man: Prospects and Promise of the New Sungei Buloh Bird Reserve' published in 1990. (Essays in Zoology, Papers Commemorating the 40th Anniversary of the Department of Zoology, National University of Singapore)

Simply put, the bird life at Sungei Buloh will be adversely affected should ever Mandai mudflats be reclaimed. His study revealed that 'Mandai does not provide the conditions required for roosting waders but the mudflats next to the Mandai mangroves are a major feeding area for the birds that roost at Sungei Buloh.'

Clearly, the management of Sungei Buloh Wetland Reserve cannot be confined within its boundary. At stake are not only the birds, but the collective investment put in through years of commitment and hard work by the National Parks Board, volunteers, NGOs and business partners alike. Also at stake are the opportunity cost invested in Sungei Buloh ever since and our reputation as a serious conservation strategist. Sungei Buloh's destiny is ecologically tied to Mandai mudflats. Undoing it could jeopardize everything we hold dear.
