Understanding the relation between biodiversity and land management

  • Effects of browsing (fencing experiment): Deer appears to be a prime disturbance in shaping tree diversity in European forests. I maintain a fencing experiment in broad leaved forest, where deer was excluded a different times after regular thinning[1][2].
  • Effects of anthopogenic nitrogen (Acatec and Leopoldina) A new project emerges in which I investigate the adverse effects of N-fertilizer in agriculture and of atmospheric N-deposition versus the enhanced growth in forests and its effect on climate mitigation. This is in fact an old topic[3][4] but a new attempt in an early stage.

Biodiversity experiments

  • Grassland experiments (The Jena Experiment) Starting the new Institute MPI-BGC in Jnea I was able to initiate the establishment of a biodiversity experiment in grassland. This experiment is now running for almost 20 years, and it is the largest installation of this kind worldwide[5].
  • Tree experiments (Biotree, Douglas Fir Experiment, Abies Experiment). In Parallel to the Jena experiment the biodiversity experiment BioTree based on trees was started. In Co-operation with the State Forest of Thuringia 3 sites were planted in various ways to investigate the effects of tree mixtures[6][7]. In continuation of the BioTree experiment a number of common gardens were established to investigate the performance of various species of Abies and of Pseudotsuga species in a changing climate[8][9].
  • Deadwood Experiment (BeLongDead) and Fungi. A major debate in nature conservation and forest management exists concerning the survival of xylobionts that inhabit dead wood. Therefore I initiated a major dead wood-experiment, in which more than 1000 logs of 13 tree species were exposed in all kinds of managed and un-managed forest in three regions of Germany. It turns out that not the total volume of dead wood but the diversity of tres species is important to maintain the xylobionts[10]. The main prerequisite for wood dwelling insects is, however, the colonization by fungi. Therefore, DNA based investigations on wood-fungi reveal the importance of tree species[11]
  • Genetics of the genus Oak and Fagus: The evolution of even common tree genera remains obscure. The huge diversity of Oak and the obscure distribution of Fagus shall be analyzed by DAN-sequencing in a European consortium. For baseline information see [12].
  • Forest Birds: Birds are taken by environmental agencies to assess the ecological conditions of ecosystems. In Germany, the abundance of a “basket” of indicator species was downscaled to 80% of a theoretical 100% value in the hope that by nature conservation measures with taking forest out of management the abundance of these species would reach 100%. I could show that nature conservation has no effect. Confining the study to non-migrating forest birds I show that the abundance has increased since 1970 in managed forests, making conservation measures redundant.

Forestry and Wood Industries

  • Depite a huge volume of information of forests and wood industries, even a compendium such as the OECD assessment on The State of European Forests avoids to showing a wood flow budget. For Germany the estimates about annual harvest range between 60 to 90 Mill m3/yr. One reason is the uncertainty of fuel wood for energy. In a European consortium we try to revise the national balances of wood flow. This is important because only by including wood for energy a comparison of climate mitigation effects of managed versus unmanaged forests become meaningful. The project is in progress, but the underlying problems are addressed in [13].

2nd Edition of the textbook “Plant Ecology”, Springer Verlag

  • I edited a text book “Plant Ecology” in 2002. It is time to revise this textbook. I hope that the new edition will be available in 2019. This text book deals with ecology in 5 Parts: (1) Molecular ecology, (2) Physiological ecology, (3)Ecosystem Ecology, (4) Community Ecology, and (5) Global Ecology.
