BELongDead (Contributing project)

Long-term Monitoring of Deadwood (BELongDead)

Research without DFG funding

The longterm experiment was established by Prof. E.-D. Schulze (emeritus, MPI Biogeochemistry in Jena) in the second phase and is coordinated by Prof. Dr. Wolfgang Weisser (Technical University of Munich, Chair for Terrestrial ecology) since the third phase.
BELongDead is not a funded project but an experiment that allows scientists from various fields of interest to investigate ecological degradation processes of dead wood.

Figure: The photo shows a row of deadwood logs in a shady summer forest.

Hypotheses

What is the meaning of deadwood in ecosystem processes?
What is the influence of the surrounding habitat?
How is the settlement of species and the decomposition of deadwood?
How does decomposition affect the carbon cycle and microorganisms on the soil surface?

Experimental setup

2008 the following tree species were put into each forest VIP in the three regions of the Biodiversity Exploratories in three replicates (in total 1,140 deadwood logs):
Beech, oak, maple (sycamore maple, mountain maple and field maple in mixture), lime tree, cottonwood tree, hornbeam, ash, birch and cherry (one log per VIP), as well as pine, larch, Douglas fir, and spruce.

Each deadwood log has a center diameter of 30cm and a length of 4m.

At the beginning of the experiment, a soil sample was taken next to each log, dried and stored, and a log slice was cut and stored.
