history

Castle oak in 1900

The oak belonged to the former park of Eisolzried Castle, which was completely demolished at the turn of the 19th century. 1737 was in the Salbuch the high Nobility Ruffini Hofmarsch Eisolzried by a lovely Aich-Wäldls reported that the Castle anger ed. The oak stands there as a leftover. The tree photographer Friedrich Stützer, inspector of the royal Bavarian state railway in Munich , wrote in his tree book The largest, oldest or otherwise strange trees in Bavaria in words and pictures :

“It will probably not be easy again to mark a lonely footpath with such a powerful signpost, as is the case with our signposts in Eisolzried, which is near Dachau. [...]
What is generally true of the oak, that it is a symbol of indomitable strength and strength, is particularly true of this tree. Despite its 700 years of age, there are still no traces of beginning decay to be seen on its majestic growth. The mighty trunk has a circumference of 8 at man height, and a circumference of over 9 meters at 3 meters; the mean diameter is 2½ meters. The first branches branch off at a distance of 6 meters from the ground, of which the stronger ones themselves have a circumference of almost 4 meters. The height is measured at 25 meters, as much as the horizontal development of the very regular treetop, which in the summer can be seen as a huge ball of leaves over the flat moorland.
Assuming that the fresh external appearance also corresponds to a healthy, rot-free interior, the wood mass of the tree is calculated to be 65  stars or about 22  fathoms of wood; a strong post for a signpost! "

- Friedrich Stützer : The largest, oldest or otherwise strange trees in Bavaria in words and pictures. 1900.

In 1900, Friedrich Stützer stated that the tree had a height of 25 and a trunk circumference of eight meters at a height of about 1.5 meters. It had a regular full crown with a diameter of 25 meters. He estimated the age of the oak at 700 years. At that time she had reached the peak of her growth potential. In the past century the oak trunk has become even stronger, but the crown volume has decreased a little. Years ago, lightning struck the crown, leaving a 40 centimeter wide groove to the ground.

The oak was placed under protection by ordinance of July 8, 1997 . On December 9, 2003, an unknown perpetrator carried out an arson attack in the hollow trunk with gasoline, which she survived.

In recent years the oak has been surrounded by a construction fence. In addition, a larger production hall was built on the spot where a small wooden hall had previously stood. The roots were damaged by the development, so that the water balance of the oak is disturbed. The hall also influences wind conditions and reduces solar radiation. The Bund Naturschutz therefore sees the oak as endangered.

description

The oak begins broad and massive at the bottom and tapers slightly towards the top. The trunk is completely hollow, open on one side and marked with a lightning groove. The trunk opening is provided with a close-meshed wire mesh. The crown, which begins at a height of about five meters, is formed by several rather strong branches, some of which have fractures at the ends. The height of the oak was given in 1990 as about 16 meters with a crown diameter of 14 meters.

The German tree archive was in 2001 at the site of the smallest diameter (waist) on a circumference of 8.59 meters and in 1994 at one meter height of 9.60 meters. At Champion Trees , a joint project of the German Dendrological Society (DDG) and the Gesellschaft Deutsches Arboretum (GDA), the oak tree is 9.06 meters high and 1.3 meters high, the so-called breast height diameter (BHD), specified. The oak is one of the ten strongest , naturally grown single-stem oaks in Germany .

The age of the oak is given differently in the literature. The Lower Nature Conservation Authority estimates it to be around 600 years old. The forest scientist Hans Joachim Fröhlich assumed an age of around 700 years in 1990. In 2009, the German Tree Archives stated 350 to 700 years. The oak stands on barren scree, so that the age is higher than that of most similarly strong oaks.
