WILD HARMONY: THE CYCLE OF LIFE IN THE NORTHERN FOREST William O. Pruitt. Saskatoon, Western Producer Prairie Books, c1960, 1983. 179pp, paper, $10.95. ISBN 0-88833-101-0. Grades 11 and up. Reviewed by Elaine Balpataky. Volume 12 Number 1 1984 January Books about the North often refer to the fragility of its ecosystems. This book brings readers to a detailed understanding of that fragility by taking them into the world of animals, plants, and native people who live in Canada's sub-arctic northern forest. The reader enters the vole's tunnels, "pads with the lynx along a hare's trail," follows the life of a spruce tree from its germination as a tiny seed dropped by a bird, through its growth, maturity, uprooting, and "travels" to its final resting place on the Arctic tundra. The reader also learns what can happen when exploitation replaces careful management and conservation in the North. Originally published in hardcover as Animals of the North (1960), this edition includes an "Epilogue for the Eighties" in which the author, a professor of zoology at the University of Manitoba, makes a plea for political action based on sound ecological research to protect and preserve the stability of the sub-arctic. Recommended for intermediate or senior classes studying the development of Canada's north. Also recommended for the student or general reader who is interested in wildlife.
