Available in PDF, EPUB and Kindle. Book excerpt: Forestry is one of the most important foundations of the Scandinavian economies. Sustainable Forestry in Southern Sweden: The SUFOR Research Project reviews the findings from the eight-year research program first launched in 1997 that searched for applicable ways to maintain sustainable forestry in the region. Respected scholars and experts discuss ways to bridge the chasm separating the world of research with the world of trade and industry. Biodiversity, the impact of humans, environmental conditions, and other facets of sustainability are all presented and discussed in detail. The book is extensively referenced and includes several tables to ensure clarity of data.

This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, forest decline has become increasingly apparent. The decline in forest health was often reported to be associated with air pollution. The present study on Norway spruce stands in the Fichtelgebirge analyses various processes interacting within forest ecosystems. It covers transport and deposition of air pollutants, the direct effects of pollutants on above-ground plant parts, the responses of soil to acid rain, and the changing nutrient availability, and the accompanying effects on plant metabolism and growth. The role of fungi, microorganisms and soil animals in the decline of these stands is also assessed. The volume is concluded with a synthesis evaluation of the influence of different factors, and their interactions on forest decline.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Effects of site preparation methods on establishment and growth of different seedling types and clones of Norway spruce were examined in this project. Two studies were established in the southern parts of Sweden. The first study aimed at investigating the effects of mulch and scarification on growth of six clones of Norway spruce in the form of rooted cuttings. In the second study, interactions between scarification treatments, including non scarified control, mounding and soil inversion, and seedling types of Norway spruce were examined at two different locations. The three different seedling types used in the experiment were a 10 weeks old containerized seedling referred to as mini seedling, a 2 year-old containerized seedling and a 2 year-old hybrid seedling (grown both as a containerized- and a bare root seedling). Mulch and scarification reduced amount of competing vegetation. Bud break occurred earlier for cuttings planted in scarification compared to control and mulch. Gas exchange and the number of new roots were higher in planting spots covered with mulch. Mulch and scarification affected survival and growth of the cuttings after the second growing season positively. Height growth was 32 mm greater and biomass increment 6 g higher in plots treated with both scarification and mulch compared to the control. Clonal differences regarding gas exchange and growth were significant. Clone 1100 had poor biomass growth, height growth and gas exchange and the lowest amount of new roots. Clone 2136 achieved the highest biomass and height growth after two years. This clone had high gas exchange values and a large number of new roots compared to clone 1100. In this study, clonal effects on growth were greater than site preparation effects. Scarification increased survival of the mini seedlings. Differences in growth between the control and scarification treatments were relatively greater for the mini seedling than for the two larger seedling types. Interactions between s.
