Potamopyrgus doci is a critically endangered species of fresh water snail native to New Zealand.
Habitat
This snail has been found in only one location in a spring at the exit of Ruakuri Cave, in the Waitomo Caves, north west of Te Kūiti. This habitat is only a few square metres in size but is within a protected area. However, there is recreational rafting in the cave and agriculture upstream may result in a decline in water quality. Despite this the population trend is regarded as being stable.{{cite iucn |author=Collier, K. |date=2013 |title=Potamopyrgus doci |volume=2013 |page=e.T198891A2544395 |doi=10.2305/IUCN.UK.2013-2.RLTS.T198891A2544395.en |access-date=12 November 2021}}
Conservation status
In 2013 the Department of Conservation classified Potamopyrgus doci as Nationally Critical under the New Zealand Threat Classification System.{{Cite journal|last1=Grainger|first1=N.|last2=Harding|first2=J.|last3=Drinan|first3=T.|last4=Collier|first4=K.|last5=Smith|first5=B.|last6=Death|first6=R.|last7=Makan|first7=T.|last8=Rolfe|first8=J.|date=November 2018|title=Conservation status of New Zealand freshwater invertebrates, 2018|url=https://www.doc.govt.nz/globalassets/documents/science-and-technical/nztcs28entire.pdf|journal=New Zealand Threat Classification Series|volume=28|pages=1–29|via=Department of Conservation}} 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.
