Excerpt from Forest Research Activities: Forest Management, Range Management, Forest Products, Forest Economics, Forest Survey, Forest Influences; February 1, 1939 Utilizing a request for advice and assistance by the local Soil Conservation Service office to further test the applicability of aerial photographs for Forest Survey purposes, two members of the Survey staff spent October and November on the Placerville ]?roject Area. In previous work on the Lakeport Quadrangle it had been found that significant differences in timber-stand conditions could easily be recognized on the photographs. However, it was also found that many of the areas thus delineated would not fit into any of the hitherto-used stand classes because they were made up of, not one, but two or more different classes. To arbitrarily force them into one or another class would be to introduce considerable varia tion in their composition, as regards both the major element and its associates. Such a-procedure would also add to the problem of attaining consistency between mappers. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
