FROG HEAVEN

In an apparently empty weedy area in the autumn woods, late rains begin a cycle of life in a Delaware vernal pool, providing a breeding place for 14 species of amphibians, as well as snakes, invertebrates and plants. Wechsler, an experienced naturalist and photographer, provides a clear explanation of the interdependence of the species and their surroundings and the importance of seasonally flooded pools not only in Delaware but across the country. His beautifully reproduced color photographs show the pond throughout the year from a distance, as well as many close-ups of its inhabitants. (A few require careful scrutiny and reading of the surrounding text for understanding.) After following the Delaware pond through four seasons, the author concludes with more general information about ephemeral pools and student action that helps preserve them. Endmatter includes a glossary, a few suggested readings (half are other books on amphibians by the author), two websites and an index. Attractive and informative, this will be welcomed by young naturalists and their teachers. (Nonfiction. 8-12)
