OUR NATURAL HOMES

In a work subtitled ``Exploring Terrestrial Biomes of North and South America,'' Collard (Do They Scare You?, 1993, etc.) introduces 12 land biomes with brief descriptions of the plants, animals, and climate of each. A double-page layout with two or three paragraphs introduces each biome, accompanied by a full-color scene of typical flora and fauna. While visually appealing (and reminiscent of museum dioramas), the illustrations can be at odds with the text, e.g., the description of the boreal forest, or taiga, notes that spruce trees ``are packed so closely together they block out light for other plants,'' while the scene shows a vast grassy area with a scattering of spruce trees in the background. A world map that brings the book to a close shows the 12 biomes with color variations that in some cases are so slight, readers will have difficulty distinguishing between temperate deciduous forests and temperate grasslands. The text lacks precision, e.g., ``This biome is a temperate place—it rarely gets too hot or too cold.'' Too hot or too cold for what? Of limited use. (glossary) (Nonfiction. 7-10)
