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 exist and are in use at international, multi-country, national and local levels as well as for consumer use.
The Sumatran water shrew is a red-toothed shrew found only in the Padang highlands of western Sumatra, Indonesia. Its natural habitats are streams in montane forests.
