empty gun emplacement at the park) and the old gun casemates) and the fort's tunnels (the so-called Labrador Secret Tunnels). Ecological projects Seagrass monitoring operations The National Parks Board, National Biodiversity Centre, TeamSeagrass and volunteers from the public regularly conduct surveys and monitoring of the seagrasses found in Singapore, in inter-tidal areas such as Chek Jawa and Pulau Semakau. The seagrass meadow at Labrador Nature Reserve is one of the monitoring sites. These surveys are part of Seagrass-Watch, a global seagrass assessment and monitoring programme spanning 18 countries with more than 200 monitoring sites worldwide. Non-destructive scientific surveying methods developed by Seagrass-Watch are adopted. Data gathered is then fed back to Seagrass-Watch Headquarters, which then analyses the trends and condition of seagrass habitats at the local, regional and global scale. Survey on intertidal sponges The National Parks Board, National Biodiversity Centre and the Tropical Marine Science Institute jointly launched a collaborative project to survey and identify the intertidal sponges around Singapore. The inter-tidal area of Labrador Nature Reserve is one of the 24 locations. Although sponges are commonly found on Singapore's shores, they are poorly known due to the limited studies conducted. The 1-year study yielded a total of 102 species of intertidal sponges. One species new to science, Suberites diversicolor, was described and a large number of 40 species of intertidal sponges were recorded for the first time in Singapore. Transportation Since the 8 October 2011, the Labrador Park MRT station on the Circle line (located just beside the entrance of the road leading to the park) offers a mode of public transport to the park. SBS Transit Ltd bus service 408 (available on weekends and public holidays only) used to be another mode of public transport to the park until 31 July 2016 (the bus service was officially terminated on the following day).
