Hotwater Physa, Physella wrighti, is an aquatic snail known globally from one location at Liard River Hotsprings Provincial Park, a small hotsprings complex located in north-central British Columbia (BC). The snail was first collected in 1973 and scientifically described in 1985 (Te and Clarke 1985). Liard River Hotsprings Provincial Park is a unique system of thermal springs that provide consistently warm lotic and lentic habitat for several populations of locally endemic animals and plants. The warm shallow marsh and aquatic environments do not freeze and allow vegetation to thrive throughout the year. Biologically, this species has likely persisted in the Liard River Hotsprings complex since the retreat of the glaciers (Remigio et al. 2001). However, the species has an isolated and localized occurrence and its distribution is limited to the Liard River hotsprings complex, which makes it vulnerable to the risk of extinction due to anthropogenic or catastrophic events. The threats to Hotwater Physa are from potential changes to the hotsprings habitat resulting from recreational activities within the park. Future interest may arise outside the park for oil and gas exploration, or renew for hydroelectric development, in which case further assessment of the threat to the source of the geothermal water outside the park will be required. The recovery goal for Hotwater Physa is to maintain and protect the population(s) of Hotwater Physa within its natural geographic range and within its current variation of abundance at Liard River Hotsprings. As such, recovery is considered biologically and technically feasible.
