新加坡淡水蟹(Johora singaporensis) is one of the three known species of crabs endemic to Singapore. This means that it is unique to Singapore and not found anyw在这里 else in the world. It is listed as critically endangered by the 国际 Union for Conservation of 自然 (IUCN) and is among the top 100 most threatened species worldwide. The crab has very stringent habitat requirements and is known to exist in five freshwater streams in Singapore (Bukit Timah 自然 Reserve, Bukit Batok和Bukit Gombak), but surveys conducted by N公园 and 新加坡国立大学 showed that the population has declined at Bukit Timah 自然 Reserve, possibly due to stream acidification, while it thrives at the other two sites.
To conserve this critically endangered species, a two-year research programme was started by N公园 and the 国家 University of Singapore (新加坡国立大学) in January 2013. This collaboration seeks to establish a feasible method for monitoring the species, evaluate the current condition of the sites w在这里 the crabs were found, and recommend remedial actions to ensure that the crab can continue to thrive in its natural environment. The study also serves to identify potential locations for population enhancement.
2014年3月27日至29日, researchers and officers from N公园, 新加坡国立大学, Wildlife Reserves Singapore (WRS), 国际 Union for Conservation of 自然 (IUCN), members of other 政府ernmental agencies and NGOs convened in the inaugural Freshwater Crab Conservation Roundtable meeting to discuss and develop an overall species conservation strategy for this endemic species. “Conservation Strategy for the Singapore freshwater crab Johora singaporensis” lists various problems faced by this species and directs ongoing and future conservation management efforts. 圆桌会议之后, a working group led by N公园 was formed to implement the 新加坡淡水蟹 Conservation strategy.
Currently N公园 is working closely with 新加坡国立大学 and WRS on a long term population enhancement and monitoring programme, as well as on the establishment of a breeding programme for Johora singaporensis.
