115 pages. "A reconnaissance level biophysical survey of the Yukon Territory was conducted during 1975. 22 ecoregions were recognized and described in terms of the biophysical data available, either collected during the survey or from literature reviewed. The primary feature used to segregate and describe the ecoregions was the vegetation on different landforms under a regional climate. This was augmented by describing the distribution and extent of permafrost, geological history and terrain features." - from Abstract. Average wear. Usual library markings. 20" x 16" colour map of the ecoregions of the Yukon laid inside back cover. Sound reference copy. Book

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
