Effect of vegetation on natural regeneration of mixed silver fir forests in lowlands: a case study from the Rogow region in Poland

Popis výsledku v původním jazyce

Silver fir Abies alba Mill. represented a historically high proportion of the natural species com- position in Central Europe, but at present, due to forest management, game damage, climate change, and human activities, its share is extremely low. This paper aims to determine the abundance, species diversity, height structure, and especially the effect of competition level (1-4) and vegetation cover (mosses, herbs, ferns, grasses, Vaccinium, Rubus, tree litter) on the natural regeneration in a fenced forest stand with dominant fir in the tree layer. Research was conducted on 27 research plots in a lowland mixed forest (194 m a.s.l.) in the Rogow region of eastern Poland. Stand volume of the studied stand was 301 m3/ha at the age of 60 years, with a fir share of 75%. The abundance of natural regeneration reached 52,667 recruits/ha, 63% of which was fir. Fir represented 74% in the initial (height 0,5 m) regeneration, while it only composed 8% of the advanced regeneration (height 0,5 m). Comparing tree layers, a decrease in the share of fir and European beech Fagus sylvatica L. and an increase of European larch Larix decidua Mill. and Scots pine Pinus sylvestris L. was observed in natural regeneration. Fir measured the lowest average height (24 cm) of all 15 occurring tree species (average height 43 cm). The mean height of natural regeneration was significantly positively correlated with vertical diversity. The tallest regeneration individuals were observed in the Rubus cover. The number of regenerations significantly (p less than 0,05) increased with vegetation cover and species richness. The highest density of fir was observed in the moss cover. The competition level had a significant (p less than 0,05) positive effect on the vertical and species diversity of natural regeneration, while its effect was negative on the proportion of fir. In terms of vegetation species, grasses had the largest effect on natural regeneration, while mosses had the lowest. Silver fir is very sensitive to silvicultural interven- tions, and it is necessary to support it with effective silviculture approaches during the ongoing climate change.
