One of the findings of this facility was that around 8 solid cubic meters (Fm) or cubic meters (m3) of wood grow back per hectare of forest every year. The annual cutting rate, i.e. the average amount of wood to be felled each year, is only around 5 solid cubic meters per hectare (Fm/ha).

One of the most important principles is formulated as follows: The character of a mixed forest characterized by oaks is to be maintained, whereby the consistent use of strong deciduous trees in the area close to the core is excluded. The old trees should therefore be left standing for the most part. A renunciation of timber use and revenue in favor of a recreational forest characterized by old trees!

Nevertheless, the preservation of the oaks in particular requires a lot of intervention by the foresters: beech and hornbeam trees in particular, which take the light away from the oaks, have to be felled. Oaks don't live forever either, so the urban forestry department takes advantage of opportunities to replant young oak forests on smaller open spaces.

"For many hundreds of years (the oaks) had withstood the storms of time, survived countless generations, wet and dry years, wars and revolutions (...) - many hundreds of times they had seen the years come and go and the people. Much love and reverence of many generations had surrounded them. Many times I have sat there by the old oaks in the forest, on the red trestle or with no other goal than to be close to the game and the forest and to find a counterbalance there in the silence of nature against the worries and hardships of the day, against excessive responsibility and for decisions that determine the fate of tens of thousands. (...) That is all over now. What lasted for centuries had to be ended in these days."
