Frogs and toads were monitored through visual and audio surveys during twice-yearly wetland visits between May-June 2006-2014. Frogs and toads were assessed by park staff for physical deformities, abundance and diversity

Calling frogs and toads are surveyed annually at permanent stations, three times during the spring and early summer, at least 15 days apart. Each survey is 3 minutes long. These surveys are conducted by park staff and volunteers.

Frogs, like all other amphibians, are declining all around the world, in both pristine and protected areas as well as suburban marshes bordered by highways. This decline is due to the combined effects of a number of factors, such as an increase in ultraviolet rays, chemical pollution, habitat destruction, overharvesting, climate change, the introduction of exotic species and the propagation of diseases and fungi. Part of La Mauricie National Park's mandate is to serve as a representative area in the protection and understanding of ecosystems. Monitoring the aquatic frog community is done through visual counts and catching frogs in transects.

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.

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.

This program captures counts of amphibian egg masses used to measure abundance and distribution trends in the breeding populations of Red-legged Frogs (Rana aurora) and Northwestern Salamanders (Ambystoma gracile) in the Long Beach Unit of the park. It is assumed that one egg-mass represents one breeding female. The Red-legged Frog is listed as a species of Special Concern (COSEWIC 2004). Surveys represent a complete visual census of selected representative lakes and wetlands (representing different wetland types, sizes and at variable distances from roads) and occur annually in the spring.

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.

All available bathymetry and related information for Frog Lake were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.
