Opacuincola eduardstraussi is a critically endangered species of fresh water snail native to New Zealand.
This snail has been found in only one location in a stream in Twinforks Cave, Paturau in the Tasman District of New Zealand. The population trend of this snail is unknown at present but it is regarded as potentially threatened by land clearance, water pollution and damage by cattle. [3]
In 2013 the Department of Conservation classified Opacuincola eduardstraussi as Nationally Critical under the New Zealand Threat Classification System. [1] The species was judged as meeting the criteria for Nationally Critical threat status as a result of it occupying a total area of less than 1 hectare. It is found only in one location and is also classified as Data Poor under the threat classification system. [1]
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
