Although selection forests have clear advantages over age-group forests in view of their total growth performance, their net product and their stability, not to mention the sustainability of their beneficial effect, the proportion of this type of forest is insignificantly small in Germany and also in mixed forest in the mountains. It is therefore all the more surprising that scarcely any discernable efforts have been made to increase the proportion of selection forests. For a conversion, an alternative model for the treatment of the stands is adopted, whereby it is no longer the encouragement of the growth to maturity of individual trees in the stand which is aimed for, but rather the transformation of the whole stand to a selection forest using available stand elements and elements created by an early initiation of regeneration. Based on his experience in the forestry district of Kirchzarten in the Black Forest, Germany, the author describes the procedure for a successful conversion. This is to be started as soon as possible, that is to say when the crown height of the trees is about 18 metres and with corresponding usable dimensions, using small group shelter-wood cuts, a so-called initial femel cut. To get the conversion started it is advisable to remove whole groups of predominantly badly situated and overgrown trees. The stand will be additionally structured later through further interventions at short intervals. In the process, here and there really well situated trees will actually be left to stand solitar y, in other places w hol e self-cont aine d groups will b e created and else where valuabl e mixed s tand elements will be selected for permanent preservation, this in order to create a situation in which there are about 35 overstorey trees per hectare. On the basis of his own cost calculations, the author comes to the conclusion that the conversion is, from a financial point of view, superior compared with the age-group forest in that it brings higher proceeds more quickly and more often.

The convulsions which seized southern Germany and Switzerland between 1520 and 1540 included the expulsion of Duke Ulrich of Württemberg (an ally of the Swiss) from his duchy of Württemberg; his intrigues to recapture his duchy by raising peasants in the Black Forest already in the throes of popular rebellion; and the beginnings of Reformed Protestant preaching by Huldrych Zwingli in Zürich. Any of these circumstances could easily have led to outright war on both banks of the Rhine. The Swiss were reluctant to give any support to Duke Ulrich, or to the peasants, though Zürich came to the aid of the Forest Town of Waldshut where Balthasar Hubmaier preached the new doctrines (and later Anabaptism). Konstanz, too, embraced Protestantism, to the chagrin of the Catholic Inner cantons. That effectively put an end to the city’s hopes of joining the Confederation.

Raids and Retaliation

The Swiss mounted raids across the Hochrhein and the Alpine Rhine, as well as taking possession of the bishop of Konstanz’s castles. The Swabian League responded with sorties south of the Rhine. These raids were mostly for booty and were followed by rapid withdrawal: there was no obvious strategic purpose behind them. Both sides employed mercenaries. It is doubtful whether the Swiss had any long-term intention of seizing the southern Black Forest or the Hegau, though military access to the four Austrian ‘Forest Towns’ was an important aim. Nevertheless, individually Zürich and Schaffhausen had territorial ambitions in the Klettgau and Hegau, respectively.

In Norway, shallow landslides are generally triggered by intense rainfall and/or snowmelt events. However, the interaction of hydrometeorological processes (e.g., precipitation and snowmelt) acting at different time scales, and the local variations of the terrain conditions (e.g., thickness of the surficial cover) are complex and often unknown. With the aim of better defining the triggering conditions of shallow landslides at a regional scale we used the physically based model TRIGRS (Transient Rainfall Infiltration and Grid-based Regional Slope stability) in an area located in upper Gudbrandsdalen valley in South-Eastern Norway. We performed numerical simulations to reconstruct two scenarios that triggered many landslides in the study area on 10 June 2011 and 22 May 2013. A large part of the work was dedicated to the parameterization of the numerical model. The initial soil-hydraulic conditions and the spatial variation of the surficial cover thickness have been evaluated applying different methods. To fully evaluate the accuracy of the model, ROC (Receiver Operating Characteristic) curves have been obtained comparing the safety factor maps with the source areas in the two periods of analysis. The results of the numerical simulations show the high susceptibility of the study area to the occurrence of shallow landslides and emphasize the importance of a proper model calibration for improving the reliability.
