Book excerpt: The greatest threats to Europe's birds and biodiversity come from loss and degradation of habitat. This book brings together more than 190 bird and habitat conservation experts from all over Europe, to examine the threats to Europe's eight major habitat types, and propose policies and actions to protect and restore them. Although the emphasis is on birds, particularly the 40 percent of European species with an unfavourable conservation status, many recommendations would help conserve all elements of biodiversity in the wider European environment. "An important contribution to the conservation of biodiversity in Europe" - Peter L Nielsen, European Commission. "An extremely valuable reference for bird conservationists in any continent" - The Wilson Bulletin.
Download or read book Repeated Manual Release in a Young Plantation written by Philip M. McDonald and published by . This book was released on 1994 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
