The Vienna Woods (Wienerwald) is one of the most important forest areas in Europe. Covering more than 4,400 hectares, the City of Vienna Forestry Department is working to make the forest climate-resilient in the long term and to preserve its valuable ecosystem services.

The Wienerwald is mainly composed of near-natural mixed deciduous forests dominated by beech and oak, complemented by black pine, ash, and maple along watercourses. This diversity provides habitat for over 2,500 animal species, 1,700 plant species, and around 600 fungi species – a true natural jewel on the edge of the city.

Yet the forest is also feeling the effects of the climate crisis: drought, heat stress, and increasing recreational pressure are taking their toll. This makes forward-looking, sustainable management all the more important.

Measures for a climate-resilient forest

Within the Wienerwald project, damaged areas are being reforested, natural regeneration is being promoted, and monocultures are gradually being converted into stable mixed forests. At the same time, protective functions such as erosion and water protection are being strengthened, and near-natural management methods are applied – in sensitive areas, even horse logging is used instead of heavy machinery.

The project demonstrates impressively how regional climate action can have an impact right on Vienna’s doorstep. Every contribution helps stabilize the forest, store CO₂, and preserve valuable habitats.
