The impact of game on forest regeneration continues to increase in Switzerland

Forest regeneration is strongly influenced by game browsing in many regions – with rising tendency. Despite methodological challenges, the studies in this issue show a consistent picture: more climate-resistant tree species such as oak, maple and silver fir are particularly affected. This endangers the protective function and slows down or even prevents the transformation into tree-rich mixed forests and their adaptation to climate change. In particular in the Alps and to some extent on the Central Plateau, silvicultural forest management aims cannot be achieved. Currently, the available heterogeneous data do not allow a detailed, regionally differentiated assessment of game influence. In order to identify and compare less pronounced changes, the creation of a coordinated, nationwide monitoring system is required. This will also make it possible to determine the success of the measures in game areas across cantons. There is sufficient knowledge available for action to be taken in relation to hunting and forestry. Targeted hunting measures to reduce game populations in affected regions, proactive forest management and a strengthening of the constructive dialogue between the hunting and forestry services are urgently required. In addition, it is necessary to examine adjustments to the hunting and forestry bases, regulations, management plans and implementation practices to achieve the goals in a swift and timely manner.
