“…This association is often interpreted as fire disturbance facilitating the local establishment of Picea (e.g. Molinari et al 2005). However, in Sudenpesä the increase of fire occurs after the initial increase in Picea with fire frequency declining once Picea becomes fully established.…”

“…The stand-scale establishment of Picea has frequently been linked to local disturbance, most commonly in southwestern Scandinavia where the increase of this species often coincides with an increase in anthropogenic disturbance (e.g. Molinari et al 2005;Bjune et al 2009). The absence of fire, once Picea becomes established, is also evident elsewhere throughout Fennoscandia where Picea has the ability to alter the fire regime from a fire prone to a predominantly fire free environment (e.g.…”

“…While the cause of this delayed establishment remains uncertain, a shift in climatic condition, specifically continentality (Giesecke et al 2008), during the early-Holocene, as well as local natural or anthropogenic disturbances (e.g. Molinari et al 2005;Bjune et al 2009) appear to have facilitated the spread of Picea. A change in fire frequency; from a fire prone pinedominated forest to a fire free spruce-dominated environment is concomitant with the spread of Picea (Ohlson et al 2011;Clear et al 2014).…”

Forest vegetation composition, including\ud dominant keystone species and floristic diversity, is driven\ud by natural and anthropogenic disturbances. Disentangling\ud these complex interactions to identify the role of species\ud competition, climate and disturbances in boreal forest dynamics\ud is challenging. Here, pollen and charcoal data are\ud used to reconstruct Holocene vegetation and fire history at\ud the local stand-scale within an old-growth Picea abies\ud (Norway spruce) forest hollow in southern Finland. The\ud aim is to reconstruct vegetation history with specific emphasis\ud on the mid-Holocene expansion of Picea and the\ud decline in deciduous species in relation to fire history.\ud Early-Holocene forest development and vegetation dynamics\ud are primarily driven by climatic variations. The\ud spread of Picea at approximately 5,200 cal BP does not\ud coincide with local natural or anthropogenic disturbance or\ud a decline in deciduous species and is consistent with its\ud regional expansion, suggesting climate as the most likely\ud control over the late establishment of this taxon. The mid-\ud Holocene decline in deciduous species corresponds to an\ud increased fire frequency suggesting a higher anthropogenic\ud disturbance (also considered as the primary reason for the\ud loss of floristic diversity in southern Finland). The ‘natural’\ud fire frequency in this local stand-scale boreal forest is lower\ud than that observed in the recent past (i.e. the time of significant\ud anthropogenic impact), yet the present-day absence\ud or low frequency of fire remains within the range of natural\ud variability observed during the early- and mid-Holocen

“…The tree species that generally dominate natural forest stands on mesic soils in Scandinavia are Norway spruce (Picea abies L. Karst), Scots pine (Pinus sylvestris L) and birch (Betula pendula Roth and Betula pubescens Ehrh) (Götmark et al 2005;Molinari et al 2005;Speed et al 2013). Other species that may be present, but in lower abundancy, include aspen (Populus tremula L), rowan (Sorbus aucuparia L), goat willow (Salix caprea L) and oak (Quercus robur L).…”

In the establishment phase, several management alternatives could be applied that affect the species composition of the future stand. In this study, tree seedling data from experiments with planted Norway spruce (Picea abies L. Karst) and naturally regenerated species, mainly Silver birch (Betula pendula Roth), were used for six simulated pre-commercial thinning (PCT) scenarios. The scenarios included both monocultures and mixed stand alternatives with various initial spacing of the planted Norway spruce (0, 1600 or 2800 seedlings) and selection of main stems based on relative heights. Further stand development and individual tree growth were simulated until final harvest. Potentially, based on findings of the seedling measurements, the stands could be mixed with five to six species, but the browsing pressure from ungulates reduced this possibility since the height growth for all species except Norway spruce was highly affected by browsing. The simulated mixtures had a small variation between the PCT scenarios for the maximum mean annual increment (about 10 %). Although the growth was similar for Norway spruce, the proportion of birch in the final stands differed from 3 to 21 % between treatments and none of the highdensity planting treatments generated a mixed Norway spruce-birch forest at the time of final felling.
