This was the third and final year of the study of sagebrush types occurring in the 11 western states. Final results of the survey of woody types of sagebrush, all of which occur only in the western United States, show that there are many more types than has been realized, and that these types cover nearly twice the usually estimated acreage. The mapping of about twenty different types is completed, and publication on this work should be forthcoming within a year. Project Number 64.
