Forest regeneration within the treeline ecotone in the Giant Mountains under climate change

Original language description

Natural regeneration of mountain spruce forests began in the Giant Mountains 25 years ago after a reductionnof severe and long-enduring air pollution. This process has been influenced by climatic change.nThe aim of our contribution was to present background data for the potential elevational shift of sprucenregeneration under conditions of climate change. These upslope shifts may also depend on constraintsnsuch as climate extremes, unfavourable soil conditions, absence of ectomycorrhizal symbionts, and lack ofnmicrosites suitable for seedlings. Since 2014, we have studied the main driving factors affecting Norwaynspruce regeneration, and in particular soil conditions, ectomycorrhizal symbionts, ground vegetation cover,nand forest health, in six transects across the treeline ecotone located on a NW-to-NE transect throughnthe Giant Mountains. Microclimatic measurements showed that the mean difference in growing seasonntemperature between the montane spruce forests and forests at the treeline was −0.54°C. The modelnHADGEM2 predicted that in 20 years the temperature at the treeline will be similar to the current one atnmontane elevations. The difference in prevailing soil types between the montane spruce forests and forestsnat the current treeline (i.e. podzol vs. ranker type) could be an important factor limiting success of thenupslope spreading of spruce. Furthermore, areas covered by microsites favourable for natural spruce regeneration,nespecially spruce litter patches, decaying wood, mosses, and Avenella flexuosa stands, werenshown to decrease with increasing elevation. It is likely that spruce will move upslope in response to climatenchange, but the process is likely to be slow or even blocked for some periods, especially by unfavourablensoil conditions and climatic extremes.
