“…Our study demonstrates the highest abundance of naturally regenerated spruce seedlings on uncleared areas, which may be a result of increased microhabitats, whereas according to Ilisson et al [34] Picea abies do not prefer any particular microsite. One of the key factors responsible for the lower regeneration of spruce in the extracted plots is the absence of dead wood, since it decreases the pressure of competitive species, for which decomposing material is not an optimal substrate [1,[35][36][37].…”

A strong windstorm in November 2004 resulted in a huge blown-down spruce forest area in the southern part of the Tatra National Park in the Western Carpathians in Slovakia, Central Europe. The aim of this work is to study the vegetation composition of spruce forest at differently managed sites four years after this disturbance. Four study areas were selected for this purpose: (i) an area where the fallen trees were extracted and new seedlings were planted; (ii) an area, which was hit by a forest fire after the extraction; (iii) an area where no active management was applied; (iv) a reference forest unaffected by such disturbance. A total of 100 plots were selected, 25 of each area type. The result of DCA and CCA analyses consistently indicated that after this short period the non-extracted and extracted areas are currently most similar to the reference forest area, while the fire affected area differed. A one-way ANOVA comparing species cover for the different plot sizes indicated some significant differences between the extracted and non-extracted plots. The abundance of certain species commonly occurring in spruce forests, such as Dyopteris carthusiana agg., Vaccinium myrtillus and Avenella flexuosa, correlated weli with the non-extracted plots, compared to the extracted plots. Coverage of these species was lowest on burned plots. The lowest Shannon-Wiener’s diversity values were recorded in burned plots. This was most likely a consequence of mono-dominant competitive species spread, (mainly Chamerion angustifolium) which profited from the altered ecological conditions following the fire. Although some differences were also registered in the Shannon-Wiener diversity index between the remaining research plots, however these were not statistically significant. The most important results of our investigations include the extensive influence of fire disturbance on vegetation. Study revealed that the wind-disturbed area is able to regenerate sufficiently without human intervention

“…In our work, this was mainly evident in Chamerion angustifolium. Investigations by Ilisson et al [34] showed that the Shannon-Wiener's diversity is highest in areas with moderate damage then followed by heavily damaged areas. The diversity of intermediately disturbed forests is higher than in the final succession stages.…”

“…General forestry practice prescribes salvage harvesting after heavy storm damage because of the fear of insect outbreaks and fire hazard (Ilisson et al 2007). For this reason only 1.55% of total area of spruce forests in the High Tatra Mts damaged by wind was left to natural succession.…”

“…Due to fear of insect outbreaks and fire hazard, harvesting fallen timber after storm damage is a standard forestry practice (Ilisson et al 2007). Harvesting directly affects both composition and function of arthropod communities through the reduction and redistribution of organic matter, compaction, changes in plant cover, and modification of microclimate, which all affect the distribution, composition activity of the soil biological communities (Mar-Oribatida in windthrown stands of the High Tatra Mts 933 Table 1.…”

Community structure of soil oribatida (acari) two years after windthrow in the high tatra mountains

Abstract:In November 2004 a catastrophic windstorm destroyed a large part of the spruce forest in the Tatra National Park (Slovakia). The majority of the windthrown area was cleared; only a small part was left uncleared, thereby allowing regeneration by natural succession. The aim of the present study was to assess the impact of the different forestry practices on soil Oribatida. Three different stands were selected for the study, where sampling took place in June and The mean abundance of adults and juveniles was several times higher in stands left for natural development (NEX) than in EXT stands. The highest species richness was observed in REF, followed by NEX and EXT stands. Ordination method showed differences in species composition between studied treatments. Furthermore, a much lower abundance of Hermannia gibba, a dweller of leaf litter and upper soil layers, was recorded in cleared stands compared to the other stands. Indeed, windthrown stands had an obvious lower species richness than control stands. The ordination method used demonstrated a significant influence of both treatment and sampling date on the abundance and species richness of Oribatida. The present study showed that clear-cutting of wind-damaged spruce forest markedly decreases the abundance of soil Oribatida compared with windthrown forest stands left to natural succession.

Natural regeneration of windthrow areas is an important issue when planning forestry measures after forest disturbances. Seedling recruitment was investigated in storm-damaged hemiboreal mixed forests in eastern Estonia. The establishment and growth of seedlings from natural regeneration was registered for tree species in soil pits and in mounds of uprooted trees in stands that were either heavily or moderately damaged. Seedling growth is expected to be better in large but shallow soil pits created by uprooted Norway spruce [Picea abies (L.) Karst.] and poorer in small but deep pits created by the hardwoods in the area, silver birch (Betula pendula Roth.) and European aspen (Populus tremula L.). The most abundant regenerating species was birch. Pits hosted larger seedling numbers than mounds, due to soil instability in mounds. Rowan (Sorbus aucuparia L.) showed significantly faster growth than the other seedling species. Norway spruce pits were preferred to pits of other species by both birch and spruce seedlings. Black alder [Alnus glutinosa (L.) J. Gaertn.] did not show a preference for pits of a certain species of uprooted tree. Both spruce and rowan preferred hardwood mounds over spruce mounds. Storm severity also affected species composition: birch predominantly occurred on pits and mounds in heavily disturbed areas, while spruce was more abundant in the moderately damaged areas. The effects of advance regeneration and surrounding stands on seedling microsite preferences should be considered in future research and subsequent management recommendations.
