Pulau Ubin, also simply known as Ubin, is an island situated in the north east of Singapore, to the west of Pulau Tekong. The granite quarry used to be supported by a few thousand settlers on Pulau Ubin in the 1960s, but only about 38 villagers remained as of 2012. It is one of the last rural areas to be found in Singapore, with an abundance of natural flora and fauna. The island forms part of the Ubin–Khatib Important Bird Area (IBA), identified as such by BirdLife International because it supports significant numbers of visiting and resident birds, some of which are threatened. Today, the island is managed by the National Parks Board, compared to 12 agencies managing different areas of the island previously.
Singapore is an island city-state and country in maritime Southeast Asia, located at the end of the Malayan Peninsula between Malaysia and Indonesia as well as the Straits of Malacca and the South China Sea. It is heavily compact and urbanised. As of 2023, Singapore has a total land area of 734.3 square kilometres (283.5 sq mi). Singapore is separated from Indonesia by the Singapore Strait and from Malaysia by the Straits of Johor.
The Sungei Buloh Wetland Reserve is a nature reserve in the northwest area of Singapore. It is the first wetlands reserve to be gazetted in Singapore (2002), and its global importance as a stop-over point for migratory birds was recognised by the inclusion of the reserve into the East Asian Australasian Shorebird Site Network. The reserve, with an area of 130 hectares, was listed as an ASEAN Heritage Park in 2003.
Pulau Semakau is located to the south of the main island of Singapore, off the Straits of Singapore. The Semakau Landfill is located on the eastern side of the island, and was created by the amalgamation of Pulau Sakeng, and "anchored" to Pulau Semakau. The Semakau Landfill is Singapore's first offshore landfill and now the only remaining landfill in Singapore.
Singapore has about 65 species of mammals, 390 species of birds, 110 species of reptiles, 30 species of amphibians, more than 300 butterfly species, 127 dragonfly species, and over 2,000 recorded species of marine wildlife.

The wildlife of Singapore is surprisingly diverse despite its rapid urbanisation. The majority of fauna that still remains on the island exists in various nature reserves such as the Bukit Timah Nature Reserve and the Sungei Buloh Wetland Reserve.
Igneous rocks are found in Bukit Timah, Woodlands, and Pulau Ubin island. Granite makes up the bulk of the igneous rock. Gabbro is also found in the area and is found in an area called Little Guilin, named for its resemblance to Guilin in South China. This area is in Bukit Gombak. Sedimentary rocks are found on the western part of Singapore, which is mainly made of sandstone and mudstones. It also includes the southwestern area. Metamorphic rocks are found in the northeastern part of Singapore, and also on Pulau Tekong, off the east coast of Singapore. The rocks are mainly made up of quartzite, and also make up the Sajahat Formation.
The Singaporean government has established four nature reserves in Singapore. There are Bukit Timah Nature Reserve, Central Catchment Nature Reserve, Labrador Nature Reserve, and Sungei Buloh Wetland Reserve.
