Vienna fights for its city trees: green life despite heat and rain!

The city of Vienna faces a major challenge: heat waves, heavy rain and other weather extremes increase the over 500,000 city trees. These trees are essential for the city climate, because they donate shadows, cool their surroundings and improve air quality. But how does Vienna protect its green lungs in times of climate change? An important component of the strategy is the intensive care of these valuable trees, such as [Econews] (https://oekoneews.at/gesunde-stadtbaeume-fuer-ein-Besseres-Stadtklima-so-Schuetzt--seine-Untungee-Unbunge-Unbunge-Unbunge.

To guarantee healthy growth and a high quality of life to guarantee the trees, the city plants between 4,000 and 4,500 new trees every year. The young plants need special attention in the first four years because they need a lot of water and care. In the hot summer, 150 employees are ready to ensure that no tree stays dry. Around 50 casting vehicles use up to 400,000 liters of water every day to supply the trees with sufficient moisture.

efficient irrigation systems

The irrigation takes place by over 1,000 automatic irrigation systems and around 25,000 "casting bags", each store 75 liters of water. These casting bags are attached around the tree trunk and in addition it is poured directly into the tree disc. These measures are particularly important to improve the living space conditions of the trees and to arm them against the increasing climatic challenges. According to Schwammstadt, every second city tree suffers from stress, not only from the consequences of climate change, but also through compressed soils, road salt and air pollution.

trees work like natural air conditioning systems: they offer windbreak, filtering fine dust and cooling through evaporation. In order to maximize their cooling capacity, Vienna promotes the sponge city principle. This concept enables improved storage of rainwater in the root room and protects the trees from heat stress. Through innovative irrigation systems and sustainable construction selection, both the urban climate and the living conditions of the plants are to be optimized, as [https://www.umweltbundamt.de/themen/klima-energie/werkzeugen-der-derbank/stadt-strassenbaeume-im-kassel) describes.

robust tree species for a greener future

Another part of the strategy is the selection of heat -resistant tree species. Over 25 suitable species are in use in Vienna. These were specially selected for the changed climatic conditions. The focus is on planting robust trees that not only survive but also thrive. Thanks to committed care, the failure rate for young trees is only 0.5 percent, which shows that Vienna is on the right track to keep its city trees healthy and alive.

This shows that the care of the city trees is not only a question of aesthetics, but also the quality of life for the Viennese population. Healthy trees not only contribute to improving the microclimate, but also offer an important habitat for animals and plants. The clear goal is to continue to bloom Vienna's green lungs in times of change. According to the motto: "Healthy trees, healthy city" Vienna remains committed and creative in his efforts to make the city green and worth living.
