Our team of the University of Vienna spent the last 2 days on a retreat at Drosendorf Castle in Lower Austria. In the wonderful ambience of the snow-covered castle we could fully concentrate on discussing how to specify and parameterize our planned dynamic multi-species models. The models we will use to simulate range shifts of alpine plant species under future climate change scenarios.
Finally this years‘ field season has started: Last week we began with the biomass removal of the above-ground neighborhood vegetation on our low-competition plots in Obergurgl and on Mt. Schrankogel. To our pleasure we could relocate almost all of our more than 3.000 marked individuals on Mt. Schrankogel and of the 4.700 individuals in Obergurgl. Now everything is prepared for the measurements which will start on the 26th of July on Mt. Schrankogel.
From 9th to 13th of May the 30th European Vegetation Conference with the topic Plant communities in a changing environment took place in Bratislava. Among the 150 participants also 2 members of the Microclim project were present. Kryštof Chytrý gave a talk on „Factzors driving the distribution and beta diversity of the Central European forest-steppe and a poster by Norbert Helm on „Drivers of meta population dynamics of a high mountain flora in the Central Alps“.

We successfully finished the first field season on Mt. Schrankogel. Between 1st July and 22nd August 30 researchers took part in the first MICROCLIM field survey at Mt. Schrankogel in Ötztal Valley, Tyrol. Under the sometimes harsh weather conditions geographers from the University of Innsbruck buried soil temperature loggers on 900 positions that were selected based on a stratified random sampling. The logger positions cover an elevational gradient from 1.800 m to 3.497 m in the summit area. At each of the 900 logger positions field botanists recorded the vegetation on a 1×1 m square using the Braun-Blanquet method. Based on the vegetation records we selected 30 random occurrences of 59 plant species that are frequent on Mt. Schrankogel and which are representative for the different habitat types. On each selected sampling point we measured parameters related to vitality and reproduction of two individuals of each species. In total 3.300 individuals were measured and 250 different vascular plant species recorded on the whole Schrankogel site in 2021.
We especially want to thank Lydia, Serafin and the stuff from Amberger hut for their precious support during the whole field season!
