The Western chorus frog, Pseudacris triseriata, is the smallest living frog in Québec, measuring between 2.1 and 3.7 cm. It is found in the lowlands of the southwestern part of the province. It inhabits and reproduces in shallow water (ponds, ditches, flooded clearings). For several decades, the chorus frog’s situation has greatly deteriorated because of the destruction of its habitat. 

In spring 2000, the Western chorus frog was officially designated a vulnerable species under the Act Respecting Endangered and Vulnerable Species.

The Biodôme, Sainte-Anne-de-Bellevue Ecomuseum and the Ministère des Ressources Naturelles (MRN) are currently working with the Western Chorus Frog Restoration Team. The aim of this collaboration is to develop expertise in keeping them in captivity, hibernation, reproduction and maintaining a captive population. Such knowledge is necessary in case a survival population is needed in the event of a massive population loss in the frog’s natural habitat.
