Journey to frog heaven. If you’re walking in the woods, you can tell that winter is changing into spring by the riot of sound that fills the air. The quacking, piping, and creaking that you hear are the sounds of frogs singing their love songs. Follow those sounds and they may lead you to a vernal pool. A vernal pool is a special pond that’s just right for frogs, salamanders, and other animals. The ecology of the pool is special, too. That’s what makes it frog heaven. With fascinating facts and stunning photographs, Doug Wechsler takes young readers to a vernal pool in a forest to show how wood frogs, tree frogs, salamanders, and other creatures survive and thrive in this Society of School Librarians International Honor Book.
