However, only a small number of detailed assessments in selected regions have confirmed a climate response on the part of forest vegetation.<\/p>\n<p class=\"a-plus-plus\" style=\"text-align: justify\">This study aimed to analyse the relative contributions of temperature and other factors to range shifts in forest vegetation by comparing old and revisited relev\u00e9s in Swiss forests.<\/p>\n<p class=\"a-plus-plus\" style=\"text-align: justify\">In order to investigate such range shifts, we revisited 451 relev\u00e9 plots in forests in all parts of Switzerland. Collected data comprise two independent samples, one dating from the 1950s (age 60 sample) on 126 plots and the other dating from the 1990s (age 15 sample) on 325 plots. We defined an indicator value for elevation to estimate the upslope and downslope range shifts of forest species. The influence of different site factors on range shifts was assessed by variance partitioning using Landolt\u2019s (<span class=\"a-plus-plus citation-ref citationid-c-r23\">2010<\/span>) averaged species indicator values. Vegetation changes were analysed by balancing both increasing and decreasing frequencies of plant species.<\/p>\n<p class=\"a-plus-plus\" style=\"text-align: justify\">Our findings show significant differences between the two survey periods, where the averaged species indicator for elevation varied greatly in both the age-60 and the age-15 samples. In addition, a significant upslope shift in the herbaceous forest layer (herbs and tree regeneration) of about 10\u00a0m per decade since the mid-twentieth century is evident. Downslope shifts were detected in the shrub\/tree layer at lower elevations, which may be explained by factors other than climate warming.<\/p>\n<p class=\"a-plus-plus\" style=\"text-align: justify\">To date, the impact of global warming on tree species composition in Swiss forests has been weaker in comparison to the effects arising from forest management and land use change. Understorey vegetation, however, shows a strong signal of upslope shift that may be explained most adequately by a combination of climate change and other factors.<\/p>\n<p class=\"a-plus-plus\" style=\"text-align: justify\"><a href=\"http:\/\/link.springer.com\/article\/10.1007\/s13595-014-0409-x\">Read the full paper.<\/a><\/p>\n<p class=\"a-plus-plus\" style=\"text-align: justify\">\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Meinrad K\u00dcCHLER, Helen K\u00dcCHLER, Ang\u00e9line BEDOLLA, Thomas WOHLGEMUTH WSL Swiss Federal Research Institute, Z\u00fcrcherstrasse 111, 8903, Birmensdorf, Switzerland Key Message: An analysis of plant species range shifts in Swiss forests shows that, to date, the impact of global warming has been weaker in comparison to the effects arising from forest management and land use change.
