| Silvopastoral systems of the Swiss Jura Mountains serve as a traditional source of forage and timber in the subalpine vegetation belt, but their vulnerability to land use and climate change puts their future sustainability at stake. We coupled experimental and modeling approaches to assess the impact of climate change on the pasture-woodland landscape. We drew conclusions on the resistance potential of wooded pastures with different management intensities by sampling along a canopy cover gradient. This gradient spanned from unwooded pastures associated with intensive farming to densely wooded pastures associated with extensive farming. Transplanted mesocosms of these ecosystems placed at warmer and drier conditions provided experimental evidence that... |

| Based on apprehending the conception of intensive use of woodland, 12 indices are selected from the aspects of economy, society, ecology and so on according to the principles of scientific systematization, collectible index and system inner linkage. A scientific evaluation index system for woodland intensive use is constructed. Range Standardization Method is adopted in order to eliminate the differences among indices; index weight is calculated by the objective variation coefficient weight method. Physio geographic condition, woodland area and forest resource of Wenhe Operating Zone in Yakeshi City, China are introduced. According to the 2004-2008 relevant statistical data, intensive use level of Wenhe Operating Zone is evaluated. Result shows that the... |

| This study describes organizational structure, functions, and facilities of forestry cooperatives in the United States. It evaluates their economic performance and explores current problem areas and potentials for future development. Cooperative organization provides woodland owners professional forestry assistance, in terms of forest management, marketing, and educational activities. Some cooperatives consistently provide these services at less than prevailing rates and obtain higher than average stumpage prices on a local basis. In addition, forestry cooperatives have the potential to play a great role in marketing alternative forest products, such as wood for energy. Woodland-owner organizations have a wide range of sizes, business activities, types of... |
