Since the present climate in Switzerland includes abundant rainfall, the climatic changes should not present any serious danger of the ground drying out. In fact, higher precipitation levels are predicted. So it would seem that climate is likely to become more luxuriant rather than more dry. These conditions – together with the entry of nutrients with the rainfall – favour the growth of ash and maple but not of oak. Even with an increase in stressful dry summer periods, a consideration of the broad areas of distribution of indigenous species shows they possess a sufficiently great adaptability. Research into the effects of physiological stress on fir trees from different provenances shows in particular that those with local origins are better adapted to the habitat than those from elsewhere. The danger of an increase in storms should be countered by strategies aimed at increased resistance – through mixed plantation regulation and thinning out – rather than avoidance strategies. Ecoforestry is basically well armed for this task. It should be even more orientated towards the adaptability and resilience of forests.

New Situation

When climatic changes are taken into account in forestry management, the question arises of the choice of tree species in order to adapt the forests to increased temperatures and stress arising from lack of water. The oak could be the main species accommodating itself to the new situation up to an altitude of about 900 m. A maximal development of this genetic inheritance adapted to our soils and the reinstallation of a network of oak forests would in fact give a new boost to the exceptional biodiversity linked to this species. In canton Vaud, the application of a sylviculture favourable to the oak would concern a relatively small and reasonable area of approximately 8,000 hectares, which corresponds to less than 20% of the surface theoretically adapted to this species, with a rhythm of rejuvenation of about 40 hectares a year.
