It was cold, it was damp from below - fortunately not from above.
The Erding Forest Owners Association had invited a sizeable group of people, headed by district chairman Rainer Mehringer and district forester Marcus Nißl, through the forest near the forest pool of Maria Thalheim, which belongs to the Heiliggeist Hospital Foundation Erding.
Maria Thalheim - "Autumn forest walk" was in the announcement, but that was a sham.
Rather, it was about concentrated factual information, including on the future issue of climate-proof forest conversion.
For Mehringer, according to all known projections, one thing is certain: "We will get the climate of northern Tuscany here." However, the district chairman thought in the periods of time that a forest owner must have in mind: 50 to 100 years.
Sure: Trees need that long until they are ripe, i.e. ready to be harvested.
Some key statements: The spruce is now a high-risk tree species and will be more or less displaced in the periods mentioned. Mehringer and Nißl agreed that the bread tree of the past will be largely ousted by the fir tree. But “bringing them up” is a difficult subject, as the excursion made clear. The fir is not only very popular with forest owners and foresters, but also with roe deer. And that has consequences. Treatments against game browsing are a must. It is the white color that the game does not like. Nißl spoke of a "deterrent" that is absolutely non-toxic, but still falls under the Plant Protection Act.
What this remedy does not prevent, the participants in the round were presented drastically: So-called sweeping damage occurs when roe deer tries to get rid of the young horns on the trees. The trees can be so battered that they are considered a total failure.
"Well, it has been properly worked up!" Mehringer scratched his head as he had to marvel at the disaster. Nißl knew what to do: if you work on large areas and have many different tree species, in his experience the pressure on the individual tree species is not as great as the fir tree. The fir tree has different location requirements than the spruce tree. “She can play with the light,” said the forester. In other words, if one or the other of the large trees under which the fir is to emerge is harvested, more light comes down. But grass and blackberries shouldn't get that big. "Otherwise we'll have the mice again."
Elsewhere, the foundation has grown the flutter ash on a larger scale and has already got it high.
At another point again, the participants were able to marvel at how it works when no natural regeneration is possible: Beeches planted in rows under the spruce stand.
The removal of the spruce is then a "fine art", according to Nißl.
"You should really leave that to the specialist companies."
