Abstract : 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)
