Managed beech tree decidious forest
The station is located in a managed beech tree forest near Beberstedt in the district Eichsfeld, it serves as a comparison to the unmanaged beech tree- mixed forest of the National Park Hainich.
At the site an aluminium tower was erected in 2001. It is 46 m high and towers 10 m above tree crown. Power is provided by 230 V line from near the forester's house Geney.
The tower is similar equipped as the Hainich tower.
In the trailer is a modem, which allows checking for the data from Jena.
