One of the first notions of nature reserves in Singapore was thought up by the then-Singapore Botanical Gardens Superintendent N. C. Cantley who, in 1882, proposed that select areas of land be preserved. In as early as 1883, the Bukit Timah Nature Reserve (as it is now known) was established, making it the inaugural nature reserve in Singapore.[2] The Singapore Nature Reserves Act officially came into action in 1971. In 1984, nature reserves took up some 2,000 hectares (4,900 acres) of the country's land.[2] This figure has been increased to 3,000 hectares (7,400 acres), as of 2009.[3]
Owing to rapid urban development, the country is in need of more land for things such as housing, which is deemed more important than nature reservation. One possible issue faced by the biosphere reserves in Singapore is that they will be turned into nothingness by the government when the need arises.[4] There was an instance when the government had wanted to reclaim part of Chek Jawa, but this was opposed by conservationists and it was ultimately not reclaimed.[8]
