Introduction

[ Home ]

This is a collection of color photographs (35mm slides) and descriptions of range vegetation types (= range cover types) taken across western North America. Included are most of the major range or native grazing types traditionally featured in Range Management texts and generally accepted by workers in Range Science and Range Management. The collection is not complete. There are still range types, a few of them major types, to be "collected" and added to this publication (eg. Florida Everglades, Great Lakes forests, Pacific Northwest rain forests, some of the more restricted desert communities). Contrariwise, included herein are some range types that formerly were very important but that were destroyed by European man (and usually ignored in texts or references) and that exist only as ecological remnants or as of local or historic importance (eg. bamboo canebrakes, California bunchgrass prairie, southern mesophytic forest). As with essentially all works on vegetation this is a started not a finished product.

The range types were arranged under headings of the major biomes (or plant formations if the reader wishes to think more restrictively in terms of vegetation): grasslands, shrublands (deserts and chaparral), tundra, alpine, savanna, forest. The wetland communities of marsh and swamp were included with grassland and forest, respectively, for convenience. 

Range subtypes (or whatever term is preferred for the major subunits of dominance or cover types) were often shown at the levels of range site (= ecological site, a term purposely avoided in these descriptions/discussions), habitat type (a term not used with range shown), natural community, vegetation series, etc. depending upon the definitive published authority from the region, state, or county in which the vegetation or land unit occurred.  

Below is a list of various topics included in the introduction portion of this presentation.  

Acknowledgements

Contributions of numerous colleagues and assistants are detailed and the author assumes full responsibility for content 

Grazing Land

Range as native grazing land or natural pasture encompassing both rangeland and forest range as major categories is defined and described in context of historical application and practical meaning. 

Range Cover Types

Range vegetation is designated by cover types identified by the society for Range Management and Society of American Forester and by Forest-Range Environmental Studies Ecosystems and Kuchler units. 

Vegetation

Range plant communities are based primarily on climax or potential natural vegetation rather than on preclimax, seral stages. 

Literature Cited

Major sources for description and classification of the native vegetation are discussed and their uses given for various purposes. 

Names

Scientific nomenclature employed is explained and objectives in choice of scientific names is specified; sources (eg. flora) are discussed and their role described.

Materials

Equipment, firm, formatting procedure, etc. is explained.
