In the mountainous canton Grisons, much visited by tourists, the forest has always had an important role to play. New challenges are now presenting themselves. The article goes more closely into two themes on the Grisons forestry agenda dominating in the next few years: the increased use of timber and climate change. With the increased demand for logs and the new sawmill in Domat/Ems new opportunities are offered to the canton for more intensive use of the raw material, wood. This depends on a reduction in production costs and a positive attitude of the population towards the greater use of wood. A series of measures from the Grisons Forestry Department should be of help here. The risk of damage to infrastructure is particularly high in a mountainous canton. The cantonal government of the Grisons has commissioned the Forestry Department to define the situation concerning the possible consequences of global warming on natural hazards and to propose measures which may be taken. The setting up of extensive measurement and information systems, the elaboration of intervention maps, the estimation of the danger potential in exposed areas outside the building zone and the maintenance of existing protective constructions through the creation of a protective constructions register, all form part of the government programme for 2009 to 2012. In the Grisons, forest owners and visitors will have to become accustomed to the fact that their forests must again produce more wood and that, on account of global warming, protective forests will become even more important than they already are today.

Trends in windthrow management during the last 50 years in Lower Valais (essay) A review on the measures taken in forests hit by storms during the last 50 years reveals the mind-set behind the evolution of management operations. In the 1960s, to remove all dead wood in a stand was perfectly normal due to timber prices. Between 1984 and 1990, vast sums of money were pumped into the improvement of forest structures facing the threat of a general forest dieback. As a consequence, only few of the windthrow areas caused by storm Vivian remained with no intervention. Vivian also marked the beginning of manifold research activities and practical terrain examination in windthrow gaps. Conclusions of this first research phase resulted in a critical assessment of the windthrow areas caused by Lothar in 1999, considering different goals than systematic removal of damage wood and the prevention of bark beetle outbreaks. Since the 1990s, retaining timber after windthrow has been lively discussed, as well as the maintenance of the protection function against natural hazards and opportunities for biodiversity. Several handbooks were developed and successfully used for the planning and defining of top priority measures in damaged forests that resulted from disturbances in 2011 and 2012 in Lower Valais. These recent disturbances together with the certainty that storms will recur led to the formation of a task force in the canton Valais, aiming to organize both logistics and funds, as well as to define management priorities regarding a next hazard.
