Free-standing beeches in the area of the slope of Hochwalddistriktsteig.
The sampling site for beech in the NP Bavarian Forest is situated in the west of the Markungsgraben (a ditch) in an altitude of 1,120 to 1,220 metres. It is exposed to the south and southeast.
The beeches, especially in areas above 1,180 metres (although since the year 2000 also in lower altitudes) were isolated by the successive dieback of old spruce in the 1990s. Moreover, many of them were damaged by falling spruce crowns. This has resulted in an increased exposure to atmospheric conditions and immission. Nevertheless, the ratio of beeches is significantly higher in the new grown forests than in the old forests.
