"Forestry" examines all aspects of the industry, from the planting of new seedlings to the inner workings of a sawmill and a pulp and paper mill. This engaging picture book uses a combination of fact and fiction to introduce young children to the people, machines and environmental concerns involved in one of America's most important resource-based industries. The America at Work series fills a need for primary-level information on natural resources, and "Forestry" helps children appreciate the work involved in bringing forestry products to their homes.
