Ozone levels are decreasing, but exposure of forests remains high

Forests in Europe still suffer from excessively high ozone levels. The good news is that ozone concentrations are declining slowly but steadily.

Cycles and importance of the larch budmoth

The grey larch budmoth is a small moth that reproduces in masses in a regular cycle of eight to ten years. Its caterpillars feed on larch needles, which causes larch forests to turn reddish brown during a mass outbreak.

Sooty bark disease – the first discovery in Bavaria

The sooty bark disease infests maple species, is found in Austria and Switzerland, and has now made its way to Germany. What does this mean for the future of the maple?

Utilisation of the sweet chestnut

Roasted chestnuts are a pleasure. But the fruits of the sweet chestnut are not the only thing we can use from this special tree. It also provides delicious honey and valuable wood.

Spreading dynamics of the European spruce bark beetle in the Black Forest National Park

The goal of the research is to identify the locations that are preferred by I. typographus and thus would be particularly at risk for infestation. To achieve this, the specific characteristics of landing sites are analyzed to determine the preferred stand and terrain structures that are preferred during dispersion.
