No, they do not talk to the trees. Nevertheless, baume uwe niedenthal and reinhard hegwein have a lot to say. Although the contact of the two engineers with the trees of the market community is basically purely visual. As long as the circumference of the trunk is not measured and a "license plate" is affixed is attached. The two employees of maschinenring franken are "certified tree inspectors" and currently on the road in the community.
A digital tree cadastre
Their tools are a bandmab, a hammer and a special device that gives a number to each tree. An "outdoor tablet" is also very important, on which the location and condition of the tree can be entered. In this way, a digital tree cadastre is created, which will be handed over to the community in the end.
Burglind" is almost forgotten again. Also that the storm that hit on 3. January moved across the country, causing great damage with unimagined violence. A not insignificant proportion of this was due to falling branches or uprooted trees.
The duty of care
What to do if you are responsible for many trees – like the mayors of the municipalities. "Road safety obligation" heibt das im amtsdeutsch. Which means that a municipality has a duty of care for its trees. Somewhat difficult when you have about 500 of them, like burgermeister klaus faatz in muhlhausen and its suburbs. Not only that it was a lot of work for the municipal building yard to be constantly behind all the grun. The employees also had to receive professional training. Two member municipalities of VG hochstadt – gremsdorf and lonnerstadt – have had an employee specially trained for this work.
Muhlhausen and vestenbergsgreuth went another way. The market towns have contracted out the inspections and entrusted them to the machinery ring. For the first time, by the way, all the trees of the municipality are now surveyed, numbered and mapped according to the geo-system.
ondition is classified
The "tree inspectors" are trained for about five days on the move in the community. Create" 80 to 100 trees they per day. "We do not look whether a tree is already or valuable", says uwe niedenthal. Only traffic safety is decisive for him. For the engineers, this means that they will carry out a "visual inspection" of the site, the crown, the trunk and the root zone undergo. With the help of GPS, the location is recorded in a digital cadastral system. The relevant data – identification number, tree species, trunk circumference – are recorded. In addition, the condition of the tree, which can be classified as "good, medium, poor, dying, dead", must be taken into account is classified.
The stage of development of the trees is also decisive in the classification: trees in the "juvenile phase", trees in the "mature phase" and trees in the "mature phase" trees up to 25 years of age need to be inspected less often than trees in the mature or old age phase. In addition, trees in inhabited areas need to be checked more frequently than trees in remote locations. Simply because the "expectation of safety" the local area is higher than outside it. And because a higher traffic volume is assumed in the inner cities.
Once the data has been evaluated, it is made available to the municipalities. Inspection lists are drawn up and the urgency and frequency of the inspections are determined. Muhlhausen spends about nine euros per tree for the first inventory. Lower costs are then incurred for future appraisals.
Start maintenance work
As mayor klaus faatz informs, next monday church and municipality will start tree maintenance works. The work was entrusted to a company that is on site with a lifting platform. The first trees to be inspected are the lime tree at the church and the trees at the cemetery. Two trees will probably have to be cut down. After that, the trees of the community receive their maintenance pruning. According to the two tree experts, these are mainly lime trees, oaks, but also many fruit trees.
