Book Description
Excerpt from Phytogeographic Survey of North America: A Consideration of the Phytogeography of the North American Continent, Including Mexico, Central America and the West Indies, Together With the Evolution of North American Plant Distribution But with the settlement of the continent and the exploitation of its resources, such as the drainage of its swamps, the removal of the original forests and the construction of irrigation works in arid districts, the original condition of the land surface and its vegetation will be changed forever. It is important, therefore, for this generation of botanists and scientists to leave in printed form, in photographs, in maps and in other illustrations 3 record of the original appearance of the country before the march of civilization has destroyed primeval conditions. This from the standpoint of the botanist is an important matter, because all future botanic and forestry work must be based on con siderations of what was the character of the native growth. Fully recognizing this fact, the writer at the suggestion of the editors of Die Vegetation der Erde, undertook ten years ago to write a sketch of the Vegetation of North America, and this volume is the outcome of the study of American vegetation, begun over twenty years ago.
