Side slope stabilisation on unstable ground

The construction of forest tracks can be a real challenge if the underlying soil is very soft. If this is the case, geogrids can be used to stabilise the side slopes. The “Mechanically Stabilised Earth” system has already been used in flysch.

Long-term storage of roundwood – an overview of methods

The forest in Bavaria as a carbon store

Forests make an important contribution towards climate protection by actively removing carbon dioxide from the atmosphere. The carbon stocks in Bavarian forests are relatively high. But how high, exactly?

Sycamore pastures, an El Dorado for mosses and lichens

Pastures with sycamore trees are biodiversity hotspots. These traditionally cultivated landscapes are home to over 500 species of mosses and lichens. Therefore sycamore pasture conservation is needed.

Progressive mortality of Fraxinus species in Austria caused by Ash-dieback, in the context of Europe

Large parts of Europe have been affected by Ash dieback which resulted in massive tree mortality. So what can be learned from the prevention strategies in the countries where this disease has long been ravaging countless forests?
