Accelerating climate change exerts strong pressure on Europe's mountain flora
Date:4/20/2012

exposed to a characteristic dry season in summer. In the higher altitudes, precipitation mainly falls as snow during winter and spring and snowmelt is crucial for water supply of mountain plants during the arid growing season.

Harald Pauli added, "The observed species losses were most pronounced on the lower summits, where plants are expected to suffer earlier from water deficiency than on the snowier high peaks. Climate warming and decreasing precipitation in the Mediterranean during the past decades fit well to the pattern of shrinking species occurrences. Additionally, much of the Mediterranean region is projected to become even dryer during the upcoming decades".

Georg Grabherr, chair of GLORIA, said, "Impacts of climate change, either through warming or combined with increased drought stress, are likely to threaten alpine plants not only on the continent, but even on the world-wide level. A number of mountain plants may resist or find colder substitute habitats somewhere in a rugged mountain terrain. Continued species monitoring will be vital for tracing ongoing ecological impacts on the diversity of alpine plant life".
