Appreciating the value of frogs and toads and what they contribute to our environment is the focus of Frogwatch USA, a class offered through Edmonds Parks & Recreation on four Wednesday nights in April. The course, which starts April 7, runs from 7-8:30 p.m. at the Frances Anderson Center, 700 Main St.

Through classes and field trips, instructor Thayer Cueter of the Edmonds-based Just Frogs Foundation will cover collecting and reporting information about frog and toad populations here in Washington and promoting an appreciation for the diversity of frog and toad species in the United States. There is a $20 advance registration fee and $5 supply fee due at first class. Children 10 and older are welcome if registering with an adult.

To register, call Edmonds Parks & Recreation at 425-771-0230 or visit www.reczone.org.
