This measure tracks changes in presence and absence of three amphibian species at 43 potential breeding sites. Each site is visited twice (where possible), to estimate and account for detection probability the Western Toad (Bufo boreas), Columbia Spotted Frog (Rana luteiventris), and Long-toed salamander (Ambystoma macrodactylum). Mount Revelstoke National Park will monitor these amphibian species using this protocol once every 3 years.

Amphibians are vulnerable to an array of
environmental changes because of their
permeable skin, a complex life history, and a dependence on moist terrestrial or wetland habitats. These attributes make them excellent indicators of the health of aquatic ecosystems. Amphibians can indicate problems of air and water pollution, drought, habitat loss and
fragmentation, the introduction of non-native species such as sport fish and bullfrogs, and the emergence and spread of infectious disease. Amphibian occupancy is determined using auditory and visual encounters surveys.
We surveyed the presence of four native amphibian species in wetlands throughout the eastern section of Banff National Park. This dataset represents detection or non-detection for each of the four species. We performed auditory and visual surveys of 60 pre-determined breeding sites . We surveyed each site two times during a sampling period between mid-April and the end of May.
Kootenay National Park samples 28 randomly selected potential amphibian breeding sites (out of possible 66) to determine presence or absence of amphibian species. Each of the 28 sites is visited 3 times every 2 years and all detected species are recorded.
Yoho National Park samples 28 randomly selected potential amphibian breeding sites (out of possible 66) to determine presence or absence of amphibian species. Each of the 28 sites is visited 3 times every 2 years and all detected species are recorded.
Annual visual surveys are used to assess annual occupancy of breeding western toads at 10 known breeding ponds. Because of their reliance on wetland habitat for breeding, western toads are used as a measure of aquatic ecosystem health. The western toad is the only amphibian native to Haida Gwaiii and was designated as a species of special concern by COSEWIC in 2002.
Amphibians worldwide are facing declines and possible extinction. Wood frogs (Lithobates sylvaticus) are the only amphibian in Kluane National Park and Reserve. They are considered an important component of wetlands and are highly valued by Southern Tutchone peoples. Threats to wood frogs in Kluane are primarily the loss of habitat due to climate change and infection by diseases such as chytrid fungus.
The Elk Island National Park annually monitors the change in amphibian occupancy by using call counts, including data collected by citizen scientists.
The health of individual amphibians, amphibian populations, and their wetland habitats are monitored in the oil sands region and at reference locations. Contaminants assessments are done at all sites. Amphibians developing near oil sands activities may be exposed to concentrations of oil sands-related contaminants, through air emissions as well as water contamination. The focus of field investigations is to evaluate the health of wild amphibian populations at varying distances from oil sands operations.
