HabitatThis 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 Kuiti.[1] 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.[2] Conservation StatusIn 2013 the Department of Conservation classified Potamopyrgus doci as Nationally Critical under the New Zealand Threat Classification System.[3] 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.[3] References1. ^1 {{cite journal|last1=Haase|first1=Martin|title=The radiation of hydrobiid gastropods in New Zealand: A revision including the description of new species based on morphology and mtDNA sequence information|journal=Systematics and Biodiversity|date=February 2008|volume=6|issue=1|pages=99–159|doi=10.1017/S1477200007002630|accessdate=}} 2. ^{{cite web|title=Potamopyrgus doci|url=http://www.iucnredlist.org/details/198891/0|website=The IUCN Red List of Threatened Species|publisher=IUCN|accessdate=5 September 2015}} 3. ^1 2 {{Cite journal|last=Grainger|first=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|publisher=|volume=28|pages=1-29|via=Department of Conservation}} External links
