SummarySalvage cutting is a frequent operation to remedy the dieback of silver fir trees (Abies alba Mill.), which results in reduced stand canopy density and formation of forest gaps. This study was conducted in the beech-fir forest range of mountainous Croatia. The aim of the study was to determine microclimate conditions and natural regeneration in large and small forest gaps. Microclimate elements were measured and the density of plants from natural regeneration determined within forest gaps, in forest gap edge areas, and in control plots. Soil temperatures were significantly affected by changes in forest gap sizes with respect to the values of air temperatures, and were highest within the gaps as compared to gap edge areas and control forest stands. Microclimate had a significant affect on the number of small seedlings of silver fir and common beech in the large forest gaps, while this was not the case for the small forest gaps.

“…Abies alba, which extends to the north-eastern border of its geographic range in Poland declined in abundance in all geographic regions (including mountain, highland and lowland populations) and in all types of plant communities, even in an associations optimal to this species, i.e., in primeval mountain forests without a direct human impact (e.g. Jaworski & Kaczmarski 1990) and upland mixed fir forest (Mazur 1989;Maciejewski 1998;Tracz 2014). Factors responsible for this process can be divided into three groups: abiotic, biotic, and anthropogenic ones, all of which hamper the natural regeneration of the species and cause the dying of trees (Sierpiński 1977), but this issue was not the aim of this study.…”

“…A majority of previous studies on silver fir focused on habitat preferences and dynamics of the species in forest communities with high abundance of this tree species, particularly beech forests and spruce-fir forests that occurred in the lower forest belt in the mountains and in mixed fir forests and the Carpathian beechwood in highlands (e.g., Matuszkiewicz J. 1977;Wojterski 1983;Mazur 1989;Izdebski et al 1992;Maciejewski 1998). During the present studies in two areas of the central part of the Roztocze Highlands, SE Poland, where silver fir reaches the limits of its massive occurrence, the species was found to be a significant admixture in a broader range of plant communities: pine forests, mixed coniferous forests, lime-hornbeam forest, maple-lime forest, xero-thermophilous oak forest, ash-alder forest, and bog alder forest; the two latter types more frequently in river gorge section areas of the SW escarpment zone of the region.…”

Abies alba and Senecio rivularis - two of 44 mountain species reported from the Roztocze Highlands, SE Poland were objects of the study. Both species reach the north-eastern limits of their occurrence in this region. In case of Abies alba, the extent of its habitat niche and possibility of adaptation to alternative niches at the range limits were investigated in two areas of the Roztocze Highlands - the Roztocze National Park (RNP) and gorge sections of four river valleys (RV) of a mountainous character. In both landscapes, fir prefers mineral soils that are too leachy for deciduous species and even for spruce. In the RV sites, fir seems to have a much broader ecological scale and often colonizes organic soils with wet mixed coniferous forests with spruce, ash-alder, and bog alder forests. The studies on Senecio rivularis are an example of long-term ecological studies at the population level, conducted in the RNP since 1987, e.g., in terms of changes in the size structure of individuals compared to the changes in the surface area covered by this population. A nearly 3-fold increase in the area inhabited by the population was accompanied by changes in the spatial organisation of the population and individual size structure dynamics, which reflects the intensification of intra- and interspecific competition, and indicates condition changes in the population area.

Stand structure of an uneven-aged fir–beech forest with an irregular diameter structure: modeling the development of the Belevine forest, Croatia

This study focuses on the problem of irregular diameter structure in a silver fir-beech selection (plenter) forest with a ''surplus'' of large diameter trees and a lack of natural regeneration and small diameter trees. We sampled 274 plots (900 m 2 each) in the Belevine research site (266.24 ha) in the mountain region Gorski Kotar (Croatia), where diameter (dbh) distribution, diameter increment, and natural regeneration were analyzed in detail. A low density of natural regeneration, weak annual recruitment of small (10 cm dbh) diameter trees (only five trees per hectare), delayed diameter growth of trees, and a low annual rate of trees reaching the next dbh class were attributed to the current irregular dbh structure. The stand development prediction for the next 50 years is based on a simulation model, which considers the current diameter structure, increment, recruitment, and future cutting regime. Intensive cutting in the first of five 10-year cutting cycles (intensity higher of 25%) is needed to initiate natural regeneration and to accelerate growth of young silver fir trees. In the next 50 years, the irregular diameter structure will be gradually improved.
