Description: The fir trees occurring in the area reach heights of up to 51 m, diameter at breast height of over 1.40 m and volume of over 40 m³. The beeches also attain considerable dimensions. The trees are 250-300 years old and the firs are among the oldest and strongest in Germany. According to the assessment, most of the giant trees were felled in the 1920s, but the area was still considered worthy of protection.
