Two Volumes. Illustrated with numerous photographs and figures. Small 4to. Original full green cloth bindings, lettered and decorated in gold. Hardbound. Arthur George Tansley (1871-1955), English botanist, a pioneer in the science of plant ecology. He coordinated a large project to map the vegetation of the British Isles. In this work Tansley showed how vegetation is affected by soil, climate, the presence of wild and domesticated animals, previous land management, and contemporary human activities. He also reviewed all known accounts of British flora and then linked the two themes, thereby demonstrating which factors are important in influencing the various types of vegetation. Very nice set. **PRICE JUST REDUCED! PLANTS W132
