The preservation of habitat trees is an important task that must have a place in urban planning.
As a treasure trove of biodiversity, selected trees can grow old and thus ensure the preservation of biodiversity in built-up areas - without much effort.
With the tree torso, which is only a few meters high, we thus secure a valuable habitat for wood-dwelling species that are dependent on old tree structures.
The measure is an arboricultural alternative to felling and serves to preserve and promote biodiversity in the course of the daily increase in land encroachment.
However, leaving tree torsos in place can lead to conflicts of interest, as aesthetic appeal is lost via radical pruning. However, the advantages outweigh the disadvantages:
Diseased trees do not need to be replaced. With crown pruning for public safety, they can be left as a tree torso for several more years.
No replanting, no watering concept, hardly any follow-up costs, and yet a safe and (traffic) worthy tree remains, which offers added value on various levels.
You can cost-effectively preserve diseased trees that are weakening in the course of climate change but need to be secured.
You increase awareness of the local population in case of larger intervention measures on trees that characterise the townscape.
You show a transparent, nature conservation and environmental policy positioning.
You prevent possible conflicts due to a lack of transparency and ensure acceptance.
You act proactively in the interest of nature conservation at a time when action is essential
You create habitat islands to ensure biodiversity and set a good example by creating public awareness and providing information
A damaged tree is worth more in its multiple functions than a replanting, and even more than a felling.
This knowledge must be put into practice.
