A practical, illustrated survey of the animal kingdom emphasizing species that affect crops, orchards, forestry, and farm environments. It outlines classification and anatomy of major groups—vertebrates, birds, mammals, insects, mites, nematodes, molluscs and other lower forms—then treats life cycles, habits, and the beneficial or harmful roles of common field and garden animals. Substantial coverage is given to insect pests and parasitic worms, with guidance on identification and control measures adapted for agriculture. Domestic livestock are largely excluded, and concise entries and figures aim to make technical material accessible to agricultural students and practitioners.
