註釋"This bulletin serves a two-fold purpose. First, it is a final report of the Black Bear Study, Federal Aid in Wildlife Restoration (Pittman-Robertson) Project W-71-R. This is a cooperative study begun in 1963 by state, federal and private agencies to investigate the problem of black bear damage to coniferous forests and gain new information with regard to black bear biology and populations. The project became inactive in 1969 with the death of the principal investigator. The project was reactivated in 1973 to allow for consolidation and publication of study findings. The second purpose is to provide persons concerned with black bear a useful and informative guide. Basic information concerning black bear damage to coniferous forests, biology, population and a summary of past and current management in Washington is provided. Hopefully, with this bulletin, the man in the field, whether a forester, a state wildlife agent or other, can find answers to the numerous questions and problems encountered"--Preface.
