Wee Yeow Chin

Description

Education

Dr. Wee Yeow Chin is a botanist by training. He obtained his B.Sc. (Hons.) in 1961 from the then University of Malaya in Singapore; his M.Sc. in 1964 from the then University of Singapore; and his Ph.D. in 1976 from the National University of Singapore.

Pineapple agronomist

He started his career as an agronomist in 1964 with the Malayan Pineapple Industry Board. Based in the Pineapple Research Station in Pekan Nenas, Johor, Malaysia, he eventually became the Chief Research Officer responsible for the planning, coordinating and implementing the research aimed at improving the canning pineapple. It was his work on the flowering of pineapple that earned him his Ph.D. 12 years later.

Academic career

In 1977 he took up a teaching position with the then Department of Botany of the University of Singapore. For the next 20 years he taught undergraduates and guided postgraduate students in their research on non-flowering plants that included algae, mosses and ferns. His was also interested in wayside trees and their use in the greening of Singapore, publishing numerous papers and authoring books on ferns, wayside trees and medicinal plants. He retired as Associate Professor in 1997 just as the Departments of Botany and Zoology merged to form the Department of Biological Sciences.

Conservation activist

Dr. Wee has always been actively involved in nature education and conservation. He served as Secretary of the then Malayan Nature Society (Singapore Branch) from 1978 to 1990, to take over the post of Chairman when the incumbent left for his sabbatical in 1990. In 1991 he became the founding President of the Nature Society (Singapore) [NSS] when the Singapore branch broke away from the parent Malayan Nature Society. His term as President was at a time when the society was suddenly thrust into the role of a lobby group championing the local nature conservation scene.

Singapore was then fast losing its nature areas to development, with most of its population housed in high-rise apartment buildings. In the late 1980s, under the prodding of Richard Hale who was then Chairman of the Conservation Group, government agreed to set aside a piece of degraded mangrove at Sungei Buloh for a bird sanctuary. In 2001 the area was officially recognised as a Nature Reserve, the first area in 23 years since independence to be declared a Nature Reserve. Following this success, the society published its Master Plan for the Conservation of Nature in Singapore in 1990. As Hon. Chairman of the Malayan Nature Society (Singapore Branch), Dr Wee received the Green Leaf Award on behalf of the society. This award was given to organisations for outstanding contributions to environmental protection and preservation.

Flushed with success, the Conservation Committee of the society began a series of campaigns to get government to protect the many areas listed in the Master Plan – as long as there was an abundance of birdlife. Filled with enthusiasm but lacking in behind-the-scene connections, the local leadership engaged in media confrontations when government failed to respond positively. Members were then new to conservation and more than a little naïve, to say the least. Eventually every single non-gazetted area listed in the Master Plan ended up being developed.

But there was one other success. This was in our battle to save the Lower Peirce forest, a gazetted Nature Reserve, from been cleared for a golf course. The almost daily media confrontation was led by Dr Wee, who was then President of NSS when the Conservation Committee Chairman declined to take up the fight as the area was not rich in birdlife. With its 80-page “environmental impact assessment” and a popular signature campaign, we succeeded in getting government to drop its plans for the golf course. And till today, the society can boast of only two major conservation successes: Sungei Buloh, in persuading government to conserver an area, and Lower Peirce, in persuading government not to destroy a piece of protected mature forest for a golf course.

Dr. Wee stepped down as President in 1995 to travel the world as an eco-tourist, studying and photographing the flora and fauna outside the Southeast Asian region that he had all the time only read about or interacted with in the Singapore Botanical Gardens. In between his travels he wrote popular articles and gave talks on various nature themes.

Ten years later Dr. Wee once again got actively involved in NSS when he, together with a few others, started the Bird Ecology Study Group [BESG]. The recognition of this group was to meet with strong resistance from the existing Bird Group that objected to the creation of a competing group dealing with birds. BESG was eventually accepted by the society as another Special Interest Group as its aims of encouraging the study of bird behaviour complemented the existing Bird Group’s recreational birding activities.

BESG set up a website (http://www.besgroup.org) that posted all aspects of bird behaviour that most birdwatchers encountered in the field but generally failed to document. This was a website just waiting to be formed, something the birdwatching community urgently needed. After six years and more than 2,300 posts on bird behaviour, the website has become a phenomenon with birdwatchers and nature enthusiasts throughout the world. And thanks to the information provided by contributors, birdwatchers are now more aware of what birds around them do.

Unfortunately, due to continuous internal bickering, the BESG broke ties with the NSS on 1st January 2012 and is now operating as an independent group.

In July 2014 Dr Wee was appointed Honorary Museum Associate, Lee Kong Chian Natural History Museum, NUS for his contribution to the field of natural history. In November of the same year he was awarded the Outstanding Science Alumni Award for his role as green advocate through his involvement with the Nature Society (Singapore) as Secretary and Chairman, and the Nature Society (Singapore) as founding President during 1978-1995.

Extra curricular activities

Dr Wee was involved in a number of nature-related activities outside his teaching duties. He was a trustee of the Nature Reserve Board (1987-89) and continued being a member of the Nature Reserves Committee (1990-96) with the formation of the National Parks Board. In 1992 he was appointed a director of the National Council on the Environmental, continuing to serve till 1997 after the organisation became the Singapore Environment Council. He was also actively involved in the Singapore Green Plan, being a member of the Work-Group on Nature Conservation (1992-93). He also served as Chairman of the Inter-Varsity Council on the Environment (1995-97). He was actively involved with the Singapore Gardening Society since the 1980s and is currently its Patron.
