Monitoring Frogs & Toads

Management practices that enhance the environmental health of your farm are also capable of producing an abundance of frog and toad species. Because of their sensitivity to changes in water quality and land use practices, monitoring frog and toad populations can help you assess the environmental impact of your management practices.

What Is It?

Monitoring frogs and toads involves learning the calls of the different species and then listening for them three times a year at one or more points on your farm. A free audio cassette tape from which to learn the calls is provided.Image

Who Does It?

Any interested member of the family can learn the frog and toad calls and do the listening counts. Working with others can add to the effectiveness and enjoyment of your monitoring activities.

When?

Listening counts should be done once, at twilight or later, during each of the three count periods: early spring, late spring, and summer.

Time Required

A listening route with three sites might take an hour, depending on the length of the route. The actual time spent listening is five or ten minutes. Preparation time needed to learn the calls will vary from person-to-person.

Materials

At home, you will need an audio player to learn the calls. On the counts, you will need a pencil and clipboard, a flashlight, the Frog and Toad Identification Guide, and copies of the Frog and Toad Record Sheet. The guide and a master copy of the record sheet are provided.
