Some Botanical Problems of the Arctic and Subarctic Regions

Abstract

Northern vegetational problems include primarily those of flora and of plant communities. A "comprehensive, descriptive flora, with keys and illustrations" has not been developed for boreal North America, but published regional lists are noted here. The study of plant communities must be correlated with climate (including microclimate and climatic change), soils, and the evolution of land forms. Training of field workers is discussed, and examples are given of problems met in the field. An outline of problems derived from the study follows the text.
