“…The Optimal stage reached the highest values of growing stock and basal area that distinguished it from the other stages; however, the stand maintained the differentiated structure. A similar structure was registered by several authors [7,29,37,66,67], confirming that forest stands dominated by shade-tolerant tree species could be strongly diversified in all stages.…”

Old-growth forests are a unique source of information for close-to-nature silviculture. In the National Nature Reserve Dobročský prales (Slovakia), a remnant of mixed old-growth forests of the Western Carpathians, we analyzed changes in tree species composition, stand structure, and creation and closure of canopy gaps. The results were based on data from forest inventories of an entire reserve conducted in 1978 and 2015, extended by detailed measurements in a research plot of 250 × 250 m. We observed the expansion of common beech (Fagus sylvatica L.) at the expense of conifers (Abies alba Mill., Picea abies L. Karst.) in all layers of the stand. Due to a lack of conifers in the category of saplings >130 cm and an abundance of coniferous deadwood, we hypothesize that this development will lead to the dominance of beech. All development stages revealed a reverse J-shaped diameter structure; however, they differed in the majority of basic stand characteristics (e.g., growing stock, basal area, tree density, deadwood volume). Most of the structural indices did not differ between development stages, confirming a relatively high degree of structural differentiation throughout the development cycle. The total gap area reached 18%, with the dominance of small gaps ≤100 m 2 . Nevertheless, only canopy gaps >100 m 2 formed by the mortality of three or more trees were of higher importance for the extensive establishment of natural regeneration.

“…Based on the sapling data, 11 years were added to the age of trees which were cored on 100 cm height above the ground, and 9 years to those which were cored at 80 cm, to get the real age. These values are similar to a study of Samonil et al (2009) who found an average time of 14 years of growth for an individual to reach the height of 1.3 m.…”

“…This allows a reconstruction of the disturbance history based on tree-ring series. However, studies using dendroecological methods for detecting disturbance frequencies and intensity in virgin forests are still scarce (e.g., Nagel et al, 2007;Samonil et al, 2009;Splechtna et al, 2005;Szewczyk et al, 2011;Szwagrzyk and Szewczyk, 2001;Zielonka et al, 2010) as coring trees in the rare remaining virgin forests is usually prohibited.…”

“…Instead, most disturbances were associated with discrete windthrow events. Such discrete events were found to cover 14.3% of the respective areas (Samonil et al 2009), and were similar to other beech-fir Carpathian forests (Ulanova 2000). Hence, the natural disturbance regime in the Romanian Carpathians, although likely to be variable among forest types and sites, does not appear to include large scale disturbances (e.g., fires, insect outbreaks).…”

“…Schelhaas et al (2003) found no evidence of large scale disturbances in the Central Pannonic region, which included the Romanian Carpathians. Furthermore, Samonil et al (2009) found no evidence of stand replacing events in the past 200 years in the flysch region of western Carpathians for a mixed beech (Fagus sylavtica)/silver fir (Abies alba)/Norway spruce (Picea abies) forest, a type of ). Instead, most disturbances were associated with discrete windthrow events.…”

The potential of large carnivores as conservation surrogates in the Romanian Carpathians

Conservation shortcuts such as umbrella species have been long used for regional protection of species whose distributions are poorly known. Although the European large carnivores-brown bear, gray wolf, and Eurasian lynx-might seem to be robust candidates as umbrella species, their actual effectiveness has been challenged. We used 10-km resolution distribution maps of mammals (n = 10) and birds (n = 55) of European conservation concern in the Romanian Carpathians, and a temporal sequence of land cover maps (1990, 2000, and 2006) to examine: (1) the spatial overlap in distribution between large carnivores and bird and mammal species of conservation concern, (2) changes in forest cover for the Romanian Carpathians during the post-communist period in relation to the distribution of species, and (3) priority conservation areas using carnivores as umbrella species. Approximately 55% of the bird and 80% of mammals species included in this study would potentially benefit from using large carnivores as conservation surrogates. The changes in forest cover during 1990-2006 were concentrated in the Eastern Carpathians, where up to 45% of the forest per mapping unit was clearcut during the study period. Implicitly, the areas of occupancy of the background species were most disturbed by clearcutting in the Eastern Carpathians. We propose that the large carnivores could act temporary as umbrella species in areas that are still relatively undisturbed, such as Southern and Southwestern Carpathians. This alternative conservation strategy will allow Laurenţiu Rozylowicz and Viorel D. Popescu contributed equally to this research. time for (1) the new established protected areas to start efficiently and (2) the forestry practices to switch from mostly uncontrolled clearcutting, lacking landscape scale management to ecologically-based practices.
