Preserving and developing old trees and thus creating habitats
The older a tree, the more species use it. This is in part due to the deadwood that can be found on old trees. Mature trees with big canopies are also unequalled when it comes to CO2 storage, providing shade, and evaporative cooling. They are monuments of times passed and we feel drawn to them. Old trees in forests or in cultivated areas often fall victim to the pressure of exploitation. Let’s give trees in gardens (and) in the city a chance!
The following collection of Internet links was selected as an example and does not claim to be complete.
- Information on the preservation of old trees and biotope wood as well as on arboriculture:

- Guidelines on Biotope wood - Information on old trees as habitats, tree inspection, biotope wood structures, and their inhabitants:
TU Berlin: Leitfaden Biotopholz (naturschutz-und-denkmalpflege.de)
- Significance of trees in public spaces - ecological factors, liability, precautions:

- How trees improve our climate - trees as natural air conditioners, trees as green lungs, habitat preservation, choice of the right tree, tree protection, and preservation of old trees:

- Almost all of Vienna's trees in open spaces in roads, in parks, and in forest-like areas are identified in a publicly accessible map (so-called tree register). The trees are even sorted according to their canopy diameters. Why not visit a tree with a diameter of more than 15 metres near you? Have fun!
