Reviews

"This visually striking and readable title describes what happens to ecosystems when alien plants or animals are introduced by accident or intention. . . The examples throughout are thought-provoking, the illustrations outstanding, and the concluding words on steps to take to keep aliens out are helpful and practical. Doyle, who specializes in environmental art, provides handsome, double-paged portraits of animals both native and new to their natural habitat, using a footnote to clue readers into which are which. Fascinating." —Kirkus Reviews

"From the book title and first line of text to the information-packed, full-page color illustrations, this overview of ecological missteps is nonstop intriguing. . . Lively personal-interest reading, this picture book for older children is fast moving, clear, and well detailed." —Booklist

"The spreads are beautifully illustrated with animals and plants that almost seem to jump off the pages. Everything depicted is labeled, and a helpful key designates which ones are native, endangered or threatened, alien, or extinct. . . Visually appealing, it should capture the interest of browsers." —School Library Journal
