Book Description
Douglas-fir seedlings on the Arcata Resource Area, Bureau of Land Management, U.S. Department of the Interior, in central coastal California, were released by chain sawing and grubbing competing vegetation around them at different frequencies (0, 2, and 3 grubbings) over a 5-year period. After 5 years, average Douglas-fir stem diameter (measured at 12 inches above mean groundline) of seedlings grubbed at ages 1,2, and 5 was 0.91 inches, and of seedlings grubbed after the first and fifth growing season was 0.95 inches. Both were significantly larger than counterparts in the control (0.57 inches). Tanoak, the most competitive species, constituted 84 percent of total plant cover in the control after 5 years, but only 25 percent on treated plots. Combined shrubs varied little between the untreated control and treated plots and averaged about 7 percent of total foliar cover. Grasses were not present in the control and only for the fifth year in treated plots. The most abundant forb, a hedge nettle, increased greatly in density in both control and treated plots. These relationships and others denoted in the paper yield valuable ecological information on species and community dynamics in both a natural and treated environment. Crew time (no overhead or travel costs) for the three grubbings was 52 hours and for the two grubbings was 44 hours.

Book Description
The book contains papers presented at a meeting by eucalyptus experts, scholars, consultants and company managers from different countries and regions. The authors report: (1) the most recent advances in eucalyptus research from different perspectives — genetics, breeding, cultivation techniques, soil nutrition, plantation management, wood utilization, etc.; (2) the world-wide extension and development of the cultivated eucalyptus as a strategic forest tree with great economic, environmental and social significance; (3) plantation management merging ecological, environmental and legal concerns in operations practised by the private sector; (4) new approaches to utilization of eucalyptus woods. This book also represents a successful combination of academic research and practical operation in managing commercial eucalyptus plantations.
