Has Site Productivity Changed? A Case Study in the Eastern Swabian Alb, Germany,the growth district Northern part of the Eastern Swabian Alb were conducted to detect and quantify site-related growth changes. Height growth served as an indicator for site productivity and its changes. A statistical sampling design guaranteed the representation of growth of trees with different ge

Growth Patterns in Forests of the Canton of Berne, Switzerland, Based on Inventory Data,ent observa- tions emerged during the last century. Gurnaud (1878), working in France, elaborated rules for the application of repeated measurements in estimating increment; this procedure is known as the control method. These rules were first applied in Switzerland by Biolley in 1890 to the forest

Diameter and Basal Area Increment in Permanent Growth and Yield Plots in Switzerland,plots of the growth and yield research. A number of these plots have been periodically measured for more than 100 years. The plots are not systematically distributed over Switzerland. The periodic resolution of the measurements lies between 4 and 10 years. In the study, the diameter increment is use

A Comparison of Analytical Approaches for Detecting Diameter Growth Trends: Case Studies from Switzorest inventories. Each of the three approaches has distinct advantages and disadvantages. To evaluate the effects of the three approaches on the detection and description of growth trends, they are applied to three identical areas: Switzerland, the Toppwald region in the Canton of Berne and the sel

Zur Schubbemessung von Stahlbetonbalkens. In recent years, the condition of European forests has been systematically surveyed. For evaluation and interpretation of actual forest conditions long-term observations are needed. Only a few forest characteristics have been monitored over long periods of time. One of these characteristics is fo

The sampling sites are mostly small lakes in the timberline zone located between 68°30’ N and 70°00’ N and at elevations ranging from 75 m a.s.l. to 515 m a.s.l. A total of 1023
