Ringhotel Joachimsthal (Berlin)
Final COST STReESS meeting (Berlin)
Extreme events associated with climate change are affecting European forests, putting ecosystem services at risk. Assessing these risks is the driving force behind “STReESS”, an interdisciplinary COST Action community operating at the overlap of different disciplines. Our tree centred, bottom-up, approach allows us to assess mechanistic understanding of short- and long-term growth responses to climate-change induced stress, including crucial aspects as plasticity, mortality, and adaptation, which largely determine forest resilience. A powerful example of the strength of this concept is illustrated by interconnecting twittering trees across Europe creating a network enabling near-real time assessment of forest stress responses and establishment of early-warning stress detection features.
During the timespan of this meeting (11 april 2016 - 15 april 2016) one tree was being monitored just outside of the Ringhotel where the final COST STReESS meeting was. It tweeted in real-time about its condition.
Birch (Betula L.)
The birch is a tree which has a wide distribution, especially in the more northern regions (Scandinavia and Iceland). It can also be found outside of Europe, such as in Asia. It reaches its maximum height (20 m) at the age of 100 year but can become older in under good circumstances. The bark is smooth on young trees with a grey colour but can become very rough on older trees with a brownish color. Birch flowers in april and may. Brich grows best in wet to moist conditions and can not cope will with very compacted soils. Grows primarily on swamp-like soils. It is an extreme light-preferring tree sprecies (pioneer species) and is one of the first tree species to appear after a clearcut.
