The paper shows the importance of a detailed study of various aspects of modern phytodiversity as an essential element of preservation of natural ecotypes for building national ecological network in the system of pan-European network. To do this, it is necessary to explore various aspects of natural and spontaneously formed vegetation. Based on the ecological specifics of the Middle Dnieper (Forest-Steppe of Ukraine), a detailed analysis of natural and artificially formed forests on the Dnipro cliffs, in ravine-beam systems and on the Dnipro floodplain is required. Peculiarities of forest vegetation conditions, distribution of tree species and ecological conditions of their growth are given. According to forest management data, the area covered with forest vegetation is 251341.3 hectares. The distribution of forest areas by edatopes is as follows: trophotopes — subors (78083.2 hectares, 31.07%), sugruds (77232.6 hectares, 30.73%), oak wood (72520.6 hectares, 28.85%) and pine forests (23504.9 hectares, 9.35%); hygrotopes — fresh conditions (183792.4 hectares, 73.13%), dry (34938.5 hectares, 13.90%), damp (19038.7 hectares, 7.57%), moist (11401.1 hectares, 4.54%), wet (1896.0 hectares, 0.75%) and very dry conditions (274.6 hectares, 0.11%). There are 62 types of forests areas covered with forest vegetation, which are dominated by fresh oak-pine forest (68319.9 hectares, 27.18%) and hornbeam oak wood (32871.8 hectares, 13.08%), a slightly smaller area occupied by fresh pine forest (17568.3 hectares, 6.99%), hornbeam-oak-pine sugrud (16952.2 hectares, 6.74%), maple-linden forest (15144.4 hectares, 6.03%) hornbeam-pine (13775.4 hectares, 5.48%) and hornbeam (9334.3 hectares, 3.71%) sudibrovas and dry maple-linden forest (12810.9 hectares, 5.10%). The composition of forest-forming species is quite diverse and is represented by 71 species of woody and shrubby plants. The main forest-forming species are Pinus sylvestris (116592.9 hectares, 46.39%) and Quercus robur (60049.7 hectares, 23.89%). Robinia pseudoacacia (26406.0 hectares, 10.51%), Alnus glutinosa (11391.7 hectares, 4.53%) and Fraxinus excelsior (7835.5 hectares, 3.12%) have slightly smaller areas, all other species occupy small areas. Identifying all the diversity of forest habitats will provide an opportunity to plan the conservation, reproduction and protection of phytodiversity, including species of sozophytes from different conservation lists, as well as to balance the provision of ecosystem services by tree plantations of the Middle Dnieper.

Scientific Value

Allocation in the forests of specially protected forest areas (SPFE) is one of the legal forms of preservation of unique in significance or location and small areas for the conservation of biological diversity of forest flora and fauna. In the forest districts of the Voronezh region, located in the forest steppe and steppe forest zones (13 and 9, respectively) during the forest inventory in 2003 11 types of specially protected forest areas (SPFE) was allocated, a total area of 54478 hectares. Together, this amounts to 13.1 % of the total area of forest fund. Studies have shown that the largest share of the area of SPFE comes on plots of forest on a radius of 1 km around the villages, gardening companies, resorts, holiday homes and camping (76.6 %), in the second place - natural monuments of regional significance (7.2 % ) , on the third-plantations of nectar-bearing plants (5.1 %). The lowest share falls on forest cultures and geographic areas of scientific value (0.1 %). The presence and spatial distribution of SPFE types in forest districts is uneven and their areas because of forest district belonging to the forest-steppe and steppe zones are different. The largest area of SPFE is in Voronezhskoe (3411.4 hectares) and Novousmanskoe (3933.8 hectares) forest districts. In some forest districts SPFEs were not allocated (Somovskoe), in other forest districts from 4 to 9 types were allocated. The greatest diversity of SPFE types is seen in Rossosh and Tellerman forest districts (9 types), as well as Anninskoe and Vorontsovskoe forest districts (8 types). Forest districts of forest-steppe zone is characterized by not only the greatest biodiversity of forest vegetation, but also a greater variety of types of SPFE compared with forest districts of the steppe forest vegetation zone. In selected types of SPFE, activities incompatible with their purpose and performed functions are prohibited from performing.

The following paper deals with the ecological and coenotical structure of the Regional Natural Monument Chelyabinsk city pine forest vegetation. The estimation was done by a cluster analysis with Sorensen-Chekanovsky (Bray-Curtis) distance measure and a flexible beta group linkage method - by non-metric multidimensional scaling, phytoindication and general discriminant analysis algorithms. The flora and coenotical structure of Chelyabinsk city pine forest plant communities are characterized by significant anthropogenic transformation. Forest-margin and meadow, ruderal and synanthropic species are insinuating and naturalizing in pine forest communities actively and supplanting typical pine forest species off communities. The studied pine forest flora synanthropic index is 32 percent. 15 plant associations were detected; its flora, dominant and constant species, coenotical structure and biotopes were characterized by principal ecological factors. The biotopes series of ecological factors replacement were identified. Biotopes series are specified by forest stand ecological structure, that determining ecological regime changes from semi-light to semi-shade and from more arid to more damp. Also biotopes form series from wet more variable moistening bad-aerated not-acid and salt enriched soils to acid aerated poor soils with contrast arid moistening. The detected Chelyabinsk city pine forest biotopes are characterized by not so fluctuation of principal ecological factors.

The Forest Vegetation of the Tolfa-Ceriti Mountains (Northern Latium - Central Italy)The forests of the Tolfa-Ceriti mountains (Latium, central Italy) were investigated through a phytosociological approach. 249 relevés were performed and treated with multivariate analysis. 13 woodland communities were identified, of which 7 belong toQuercetalia pubescenti-petraeae, 1 toFagetalia sylvaticae, 1 toPopuletaliaand 4 toQuercetalia ilicis. The thermophilous Turkey oak-forests occurring on the trachytic hills of the Ceriti Mountains and on the flysch substrates of the Tolfa Mountains were included inRubio peregrinae-Quercetum cerridisass. nova.Quercus cerrisandFraxinus angustifoliasubsp.oxycarpawoodland communities of the footslopes have been ascribed toFraxino oxycarpae-Quercetum cerridis, while the widespread mesophilus Turkey oak forests have been ascribed toMelico-Quercetum cerridis. Cephalantero longifoliae-Quercetum cerridishas been restricted to acid and oligotrophic soils.Quercus petraeawoodlands, occurring on trachytic substrates have been described as a new association namedCarici olbiensis-Quercetum petraeaeass. nova. All these mixed oak woods have been included in the allianceCrataego laevigatae-Quercion cerridisArrigoni 1997. The nomenclatural problems concerning the prior nameTeucrio siculi-Quercion cerridisUbaldi 1988 are also discussed. The beech forests of the higher altitudes have been included inFraxino orni-Fagetum sylvaticae, while theAlnus glutinosaravine woodlands have been described as belonging to the new associationPolysticho setiferi-Alnetum glutinosae. Secondary communities ofAcer monspessulanumandAcer campestredeveloped on flysch substrates, and ofErica arboreaandArbutus unedo(Erico-Arbutetum unedonis) developed on trachytic substrates, have also been identified. Finally two types ofQuercus ilexwood have been identified:Cyclamino repandi-Quercetum ilicis, on sandstones, and the new associationArbuto unedonis-Quercetum ilicisass. nova on volcanic soils. This latter community can be considered as a coenological and geographical vicariant in central Italy of the sicilianErico-Quercetum ilicis.

Purpose. Botanical analysis of existing vegetation in the territory of the “Beremitske” Nature Park for further zoning and selection of individual territories where reproduction of the original state of the phytocenosis is planned. Methods. Field research methods for the analysis of the taxonomic composition of the flora in the park, cartographic methods for zoning the area and historical analysis of the land use of the former landowners. Results. The conducted flora monitoring showed that in the studied territories the adventitious and synanthropic species predominated, in particular in the meadow-steppe areas the invasive and synanthropic vegetation was represented by Ambrosia artemisiifolia, Asclepias syriaca, Amaranthus retroflexus, Arctium lappa, Sonchus arvensis, Tanacetum vulgare, Medicago lupulina, Verbascum phlomoides, Urtica dioica. Among the wood forms Betula pendula, Robinia pseudoacacia, Picea abies, Pinus sylvestris, Pinus sylvestris Populus nigra, Alnus glutinosa, Carpinus betulus predominated. Among the rare plants we identified the accumulation of Iris sibirica in some meadow-swamp areas. The scheme of the park has been developed and the starting points at which flora reproduction is planned to be identified. Conclusions. The species composition of the phytocenosis showed the predominance of invasive vegetation species in some areas of the park. The growth sites of the endangered species of Iris sibirica have been found, and in the future will allow to design new ecological trails in the park and to reintroduce it to other suitable sites. The data obtained will allow to develop a scheme of restoration of the original floral biodiversity in the park, taking into account the identified features.

The Impact

Abstract Replacing native forests by alien tree plantations can lead to changes in the species composition of the understory. However, differences in the understory species spectrum can also be a part of the natural variability of forest stands. We have tested the suitability of the twin plots method for an evaluation of the impact of alien trees on the species composition of the understory. This research was conducted on an alluvial plain (SW Slovakia) that was originally covered by a hardwood floodplain forest. The study was based on 7 twin plots of black locust (Robinia pseudoacacia) and native forest plots, with a maximum distance of 100 meters between the members of the twins. The dissimilarity of the plots within the black locust forest was significantly lower than the dissimilarity between the twin plots. In addition, the dissimilarity of the plots within the hardwood floodplain forest was also significantly lower than the dissimilarity between the twin plots. Under the same environmental conditions, the higher dissimilarity of the twin plots was caused by major edificators and their impact on the understory vegetation. The twin plots method proved to be a suitable tool for analyses of the impact of alien trees on understory vegetation.
