Within the Nineteen Nineties, the proportion of broken wooden was nonetheless round 30 per cent. This broken wooden can nonetheless be reclaimed, however it fetches decrease costs. In complete, Federal Forests incurred prices of 32 million euros attributable to damages final 12 months.
The commonest tree in Austria, the spruce, is most affected by local weather change. The proportion of timber will in all probability lower from round 60 to 40 per cent (see graphic). Adapting the forest to the altering weather conditions is a “century venture”, says Schöppl.
Final 12 months Federal Forests invested 15 million euros in forest administration, of which seven million went to combating bark beetles alone. These investments repay anyway, mentioned the co-chairman Andreas Gruber. Just because a 3rd of the federal forest areas are so-called protecting forests. Particularly on alpine slopes, will probably be cheaper to keep up these than to construct technical limitations to guard in opposition to avalanches and landslides.
Forest building
For a forest to thrive beneath altering situations, its composition should additionally change. To attain this, timber should develop that may address the situations in 50 years’ time.
“With local weather change in thoughts, you will need to plant totally different tree species,” says Simon Jansen from the Division of Forestry on the College of Pure Assets and Life Sciences to KURIER. This will even unfold the danger. It isn’t nearly the kind of timber, says the researcher. As a result of tree species adapt to the situations wherein they develop over generations. Should you count on much less rainfall in a area sooner or later, it might be value attempting to make use of seeds from areas which were drier up to now.
The federal forests are essentially depending on pure regeneration of the inhabitants, though in some areas this should be achieved. Final 12 months, workers planted one and a half million younger timber. The choice was tailored to the weather conditions anticipated within the respective forest space. A complete of 35 totally different tree species have been planted, most of them larch, but in addition 140,000 silver firs and 80,000 drought-resistant oaks.
Nonetheless, there isn’t any cause to concern that Austria will run out of forest areas attributable to local weather change. In a long-term comparability, these have truly turn into bigger attributable to sustainable administration.
