Raumer, H-G: Die Hochmoorwälder des süddeutschen Voralpengebietes: Moorökologische Bedeutung und zukünftige Entwicklung im Klimawandel - Raised bog forests in the South German prealpine bog region, ecological importance and development in global change scenarios, Telma, 48, 13-48 (2018)
Raised bog forests cover more than 50% of the not cultivated bog area of the prealpine bog region. 568 sites in 391 bogs are allocated to 13 raised bog forest types (defined by vegetation composition and structure) and differentiated in the precipitation gradient from 1730 to 815 mm/a. Animals (mainly invertebrates) where allocated to the different bog forest types. An exemplary table shows the great importance of a broad variety of forest types to maintain biodiversity of, unfortunately not well explored, animal groups. The hydrological importance of raised bog border forests is highlighted by the stabilisation of the akrotelm of the open raised bog plain, this is quantified by the development of the Feßlerfilz test site between 1969 and 2015. To get a better understanding of the water retention in bog forests, the decompo- sition degrees after VON POST (1924) are allocated with the hydraulic connectivity measured in undis- turbed peat cores in the laboratory. The simulation of the development of the site in two scenarios of global climate change indicates that in a dry scenario only very few raised bogs directly at the alpine fringe remain stable. In the dry belt, heather forests should get in the focus. In the whole gradient oligotrophic basins of former peat cuts are sanctuar- ies for wet raised bog communities and their allocated species. The control of nutrient input is essential for their maintenance.
