The soils formed on sandstones in sessile oak forests (Quercetum montanum typicum Cer. et Jov. 1953) were researched in the area of Fruska Gora. On permanent sample plots established in management units ?Cortanovacka Forest-Hopovo-Velika Remeta? and ?Beocin-Manastir-Katanske Livade-Osovlje?, in the are of NP ?Fruska Gora?, aiming at the monitoring of the effect of light regime on the development of sessile oak progeny in the given environmental conditions, based on the morphogenetic characteristics of the soil and analytic values of the soil properties, and based on the soil classification by Skoric et al. (1985), the following two soil types were defined: acid brown soil (dystric cambisol), and illimerised soil (luvisol). Acid brown soil belongs to the form of medium deep soils, and illimerised soil is classified as deep soil.

The soils in sessile oak forests were studied at three localities in the region of Northeast Serbia. Brownised dystrict humus-siliceous soil was studied on gneiss in M.U. "Zlatica" - N.P. "Djerdap", in the forest of sessile oak with fescue grass (Quercetum montanum subass. festucetosum heterophyllae). Dystric acid brown soil on gneiss was studied in the region of F.E. "Severni Kucaj", M.U. "Ravna Reka", in the community of sessile oak and hornbeam (Querco-Carpinetum moesiacum), and in the region of the Teaching Base "Majdanpecka Domena" in M.U. "Crna Reka - Pek", in the forest of sessile oak with hairy sedge (Quercetum montanum subass. caricetosum pilosae) on schist's. Eutric brown soil was studied on amphibolite schist and on basic and neutral eruptive rocks in the region of N.P. "Djerdap", in M.U. "Zlatica", in the typical sessile oak forest (Quercetum montanum subass. tipicum).

The height-diameter curves of natural even-aged Hungarian oak, sessile oak and Turkey oak forests in the regions of Staro Oryahovo, Sherba, Tsonevo and Aytos Forestry Districts have been studied. In order to explore the shape of the curves and, in particular, their steepness, the steepness index SI of Douhovnikov (“the method of natural indicators”) was applied. The curves were divided into three groups according to it: flat curves, medium steep curves and steep curves. Both the traditional height-diameter curves and the corresponding relative curves of Tyurin were studied. Consideration of the traditional height-diameter curves gives a certain ground for investigating to-gether the height-diameter curves of Hungarian oak and sessile oak, disregarding the tree species. This inference was confirmed by comparing the relative height-diameter curves for Hungarian oak, sessile oak and Turkey oak with Tyurin’s uniform curve of relative heights. For these comparisons we used the Willcoxon test. A statistically significant great proximity in their shapes was found. As a uniform average curve of relative heights has been established for all tree species, this proximity indicates a possibility of creating a single fan of height-diameter curves for high Hungarian, sessile and Turkey oak.

Natural Stands

This research was carried out in natural stands of sessile oak (Quercus petraea agg. Ehrendorfer 1967) on Miroc mountain. Three comunities were investigated: Pure sessile oak forest (Quercetum montanum Cer. et Jov. 1953. s.l.), sessile oak-common hornbeam forest (Querco-Carpinetum moesiacum Rud. 1949. s.l.) and sessile oak-balkan beech forest (Querco-Fagetum Glis. 1971). Pure sessile oak forests are found on the following soils: dystric ranker and acid cambic soil on sandstone, dystric ranker and acid cambisols on phyllite, and acid cambic soil on schists. Sessile oak-hornbeam forests grow on sandstone, granite and schists. Sessile oak-beech forests are found on acid cambisol on phyllite and sandstone conglomerate. Various ecological conditions (exposition, slope, altitude, soil types and bedrock) on Mt Miroc caused the occurence of diverse sessile oak forest communities, while different states of these forest stands resulted from the implementation of management measures.

Characteristic Species

The sessile oak forests found on the northeast of the Iberian Peninsula are ascribed to the Lathyro-Quercetumpetraeae association and play a key role in understanding the ecology of this habitat, as this region represents its xeric limit. For this reason, we analysed the biodiversity patterns and current conservation status of the sessile oak forests in the region. To do so, we collected Braun-Blanquet inventories of 34 plots randomly distributed throughout the sessile oak forests. The results showed a relationship between the climatic conditions and the biodiversity variables. While the richness of the community increased with decreasing temperatures, the characteristic species found within the community decreased at these same temperatures. This result was due to the presence of most companion species in the cool zones at high elevations.Sessile oaks are found close to other communities, such as silver birches and Scot pine forests.On the other hand, in the warm areas at low elevations, the sessile oak community was more established, with plants typical of this type of forest. These slightly warmer zones with sessile oaks are very important in terms of conservation and more vulnerable to climate change and the thermophilization of the community, as has been studied. As such, protecting and managing these forests is key to conserving this community. Nevertheless, as current protection measures do not safeguard most of these forests, it is essential to define a conservation strategy to preserve them. Using the conservation status, we have established criteria to improve the conservation strategy for sessile oak forest on the NE Iberian Peninsula.

AbstractAimsOur aims were 3-fold: (i) to determine whether global change has altered the composition and structure of the plant community found in the sessile oak forests on the NE Iberian Peninsula over the last decades, (ii) to establish whether the decline in forest exploitation activities that has taken place since the mid-20th century has had any effect on the forests and (iii) to ascertain whether there is any evidence of impact from climate warming.MethodsWe assess changes in the plant community by comparing a current survey of sessile oak forest with a historical data set obtained from previous regional studies dating from 1962 to 1977. We analyse the regional changes in the community in terms of biodiversity variables, species composition and plant traits. Furthermore, plants traits such as plant life forms and chorological groups are used to discern any effects from land-use changes and climate warming on the plant community.Important FindingsThere has been a loss of diversity in the community and, in the hottest region, there is also a loss of species richness. The composition of the community suggests that, although significant changes have taken place over recent decades, these changes differ between regions as a result of the low impact global change has had in the western regions. For instance, while the tree canopy cover in the western sessile oak forests remains stable, the eastern sessile oak forests are still recovering from the former exploitation that led to a loss of their rich and abundant herbaceous stratum. In fact, the recovery process in the Catalan Pre-Coastal Range has constituted an increase in the Euro-Siberian plants typical to this community. Moreover, in the eastern forests, there is evidence that climate warming has impacted the thermophilization of the sessile oak forests found on the Coastal Range.

This paper presents a typology of oak forest communities in SW Poland. Numerical classification and ordination methods were applied to distinguish the main vegetation units and to identify the environmental gradients affecting their composition. The ecological preferences of the studied communities were analysed using both measured variables and Ellenberg indicator values combined with a modified permutation test. Six vegetation units were distinguished: the association Viscario vulgaris-Quercetum petraeae mainly occurs on shallow, skeletal soils on nutrient-poor substrates in dry habitats, the association Luzulo luzuloidis-Quercetum petraeae in oligotrophic, dry-mesic habitats on moderately steep slopes and plateaux, the association Calamagrostio arundinaceae-Quercetum petraeae in mesic, oligo- and mesotrophic habitats on gentle slopes and plateaux, the community Galium verum-Quercus petraea on ultrabasic substrates of serpentine monadnocks, the association Sorbo torminalis-Quercetum in dry-mesic, mesotrophic habitats on steep, sunny slopes with initial, but relatively mineral-rich soils, and the association Melico pictae-Quercetum roboris in mesic, mesotrophic habitats with deep soils and mineral-rich substrates on gentle slopes and plateaux. The species composition of the syntaxa identified here is mainly influenced by the type of bedrock (particularly its base-richness), soil reaction and nutrients. If there are no differences in base-richness, the second most important factors are those associated with land relief (especially slope inclination) affecting light availability and moisture.
