Available in PDF, EPUB and Kindle. Book excerpt: The paper describes the characteristic vegetation types and their ecology in the Yukon Flats Region, Alaska, and associates aerial photographic patterns with these types. The discussion includes the physiographic setting, vegetation patterns, forest fires, bog succession, the selection of sample sites, vegetation sampling, photographic interpretation, composition and structure of vegetation, and radar and thermal imagery. Appendix A lists the scientific and common names of plants, while Appendix B tabulates selected soil samples from vegetation stands. Ground and air reconnaissance were used to select 43 stands representative of the common plant communities. Ten individual trees were harvested by meter increments, and stem, branch, and leaf components were weighed. Three kinds of vegetation type maps were constructed from an examination of aerial photography by application of the ground data to photo interpretation. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This monumental work by the world's preeminent authority on Arctic floras--the first comprehensive, up-to-date botanic manual for this region--is the product of the author's more than forty years of study of circumpolar floras. The book describes and illustrates all flowering plants and vascular cryptograms known to occur in Alaska, the Yukon, the Mackenzie District, and the eastern extremity of Siberia. Some 1,974 taxa, belonging to 1,559 species, occur in this region; all are described. For 1,735 of these, the book provides detailed description, nomenclature, plant drawing, and range maps. In each case, one map gives distribution in the Alaskan region; a second, on circumpolar projection, gives worldwide range. This volume is the first major flora to assemble such comprehensive range data and to provide such maps. An analytic key to all species described is provided for each genus, and there is an artificial key to families. An Introduction describes the past and present climatic, geologic, and ecologic character of the regions covered, the history of botanical collection in these regions, and the book's treatment of botanical and taxonomic details; and lists the plants of neighboring regions likely to occur. Glossary, plant authors' list, bibliography, and indexes are provided. The superb drawings were prepared by Dagny Tande-Lid, and eight pages of illustration in color are included.
