Amphibians, a diverse class of animals encompassing frogs, toads, salamanders and newts, exhibit a unique lifestyle, transitioning from aquatic larvae to terrestrial adults. Notable for their permeable skin and ectothermic nature, these organisms are integral to both aquatic and terrestrial ecosystems.

Amphibians are strong indicators of environmental health due to their sensitivity to ecological changes. However, their global decline, attributed to factors like habitat loss, pollution, climate change, and diseases, underscores the urgent need for conservation efforts.

Prince Edward Island is home to 10 amphibian species.

The Amphibian Life Cycle

Egg Stage

Larval Stage


Adult Stage

The life cycle of amphibians varies between species, and some may skip certain stages, adapting to their specific environments. 

Amphibian Surveys

Common surveys used to monitor amphibians include cover board surveys and call surveys

Cover board surveys involve the use of artificial cover objects, such as wooden boards or metal sheets, placed on the ground to attract and provide shelter for amphibians and reptiles. 

Call surveys include monitoring an area of interest by listening to frog calls at peak hours of activity and distinguishing between all species that are present.

Because amphibians are so sensitive to pollution, monitoring the whereabouts of these creatures helps us to better understand the overall health of an area!
