Since the founding of Singapore in 1819, more than 95% of its estimated 590 square km of vegetation has been cleared. At first for short-term cash crops and later because of urbanization and industrialization. 61 of its original 91 bird species has been lost leading to many native forest plants not being able to reproduce because of loss of seed dispersal and pollination.
In Singapore, the former has been the most common method until recently, with sand the predominant material used. Due to a global shortage and restricted supply of the required type of sand (river and beach sand, not desert sand), Singapore has switched to polders for reclamation since 2016 — a method from the Netherlands in which an area is ...
The Singapore Index on Cities' Biodiversity would measure performance and assign scores based on three categories. [8] [unreliable source?] Biodiversity – the number of plant, animal and other species that exist in a city; The services that these plants and animals provide, such as pollination and as carbon sinks

The tree in question was a Hopea sangal, or Chengal pasir tree, a rare tree reputed to have given Changi its name. In addition, the tree was standing in a tree conservation area, which forbids any unauthorised felling of a tree with a girth above 1 metre. The tree in question had a girth of 3.4 metres. [2]
Estimates made in 2003 have said that the rapid habitat destruction will culminate in a loss of 13-42% of populations in all of Southeast Asia. [5] To combat these problems, the Singaporean government made the Singapore Green Plan in 1992 and the new Singapore Green Plan in 2012 to continue it. The plan aims to keep tabs on the unstable ...
Plants are mainly used to beautify the landscape of Singapore. The national flower is a hybrid orchid, Vanda Miss Joaquim. [1] Large tropical tree. As in any tropical rainforest Singapore is home to a number of very large trees from the families Apocynaceae, Dipterocarpaceae, Fabaceae, Malvaceae and others.
In shifting agriculture, after two or three years of producing vegetable and grain crops on cleared land, the migrants abandon it for another plot. Land is often cleared by slash-and-burn methods—trees, bushes and forests are cleared by slashing, and the remaining vegetation is burnt. The ashes add potash to the soil.
