Water availability as a key factor of forest dynamics in protected areas - long-term perspectives inferred from tree rings
Walter Oberhuber, University of Innsbruck (AT)
Tree ring studies provide a long-term perspective of tree growth and stand dynamics and allow evaluation of forest stability in response to environmental variability. The impact of environmental extremes and climate change on tree growth was determined in two contrasting forests located within protected areas in the upper Inn valley: a drought-exposed Scots pine forest (Tschirgant-Bergsturz) and a grey alder dominated riparian forest (Mieminger and Rietzer Innauen). Results revealed compelling evidence for drought-induced Scots pine mortality and invasion of alder stands by conifers.
