FrogWatch Ontario

FrogWatch Ontario is a fun, easy amphibian monitoring project for people of all ages. It's a great activity for schools, families, cottagers, and community and naturalist groups across the province


FrogWatch Ontario is part of the national initiative, FrogWatch Canada, administered by Naturewatch. Adopt-A-Pond is the provincial coordinator of the program. FrogWatch Ontario is a partnership between Toronto Zoo's Adopt-A-Pond Wetland Conservation Programme, NatureWatch, the David Suzuki Foundation, Nature Canada, the University of Ottawa, and Wilfrid Laurier University.

You can listen for frog and toad calls in the spring and summer and help to save amphibians in Ontario! Adopt-A-Pond can help you learn to identify frogs visually and by their calls using our online resources! Contact Adopt-A-Pond to receive a hard copy of our FrogWatch Ontario Package or see our on-line Amphibians of Ontario guide to learn more about the frogs in your area. All data collected online is shared with the Natural Heritage Information Centre (NHIC) and the Ontario Reptile and Amphibian Atlas at Ontario Nature.

Why should I participate?

Over time, trends in Frogwatch observations may detect measurable climatic change in Ontario! Frogwatch data also contributes to scientific databases on frog distributions in Ontario.

  1. Frogwatch Observations help scientists:
    • track climate change using phenology (the study of times of recurring natural phenomena) data
    • identify positive and negative population trends
    • learn about range and distribution of frogs and toads (especially in the northern extent of known ranges)
  2. It's a fun, easy family or community activity which can lead to protection of wetland habitat & species
