Pyrolo-Pinetea and Vaccinio-Piceetea classes in the Burla ribbon pine forest vegetation cover.

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 Gulf Of Finland

Biogenic pollution of water bodies and their eutrophication is one of the most serious environmental problems of our time. One of the sources of water pollution with biogenic substances is forests, which belong to the background sources of biogenic load. Currently available methods for assessing the removal of nutrients from the forest vegetation cover do not provide the desired results, which causes an urgent need for their improvement. This article describes the method developed by the authors of geoinformation modeling of removal of biogenic substances from the forest vegetation cover to water bodies, taking into account the spatial distribution of vegetation in the catchment area, its species composition and absorption of biogenic substances during their migration. The Eastern part of the Gulf of Finland was adopted as the object of testing of the developed method. this is due to the fact that eutrophication processes are actively manifested within its water area. The volume of the background biogenic load on the Gulf of Finland, formed during the decomposition of the fall of the natural vegetation cover in the catchment area, was determined based on the specific removal of biogenic substances from plant communities and their absorption during migration “plant community — water object”. The total background biogenic load on the eastern part of the Gulf of Finland, formed as a result of decomposition of natural vegetation cover, was 170.21 t/year for the northern catchment for nitrogen, 12.14 t/year for phosphorus, and 207.31 t/year for the southern catchment for nitrogen , and 15.68 t/year for phosphorus. The data obtained do not contradict the results of other authors who study the background biogenic load on the Gulf of Finland. The method can be effectively used in the development of measures to reduce the nutrient load on water bodies and planning of economic activities in catchments.

Rate Of Succession

The Grand Bend succession can be divided into three periods: a colonizing stage, up to 1600 years; a transition period from 1600 to 2900 years; and a persistent stage from 2900 to at least 4800 years. The colonizing stage is dominated by grasses, Juniperus spp. and Quercus prinoides. Transition begins when persistent species invade at certain points; the earliest species are usually Quercus velutina × rubra, Rhus aromatica, and Prunus virginiana. During the transitional period the patches of persistent vegetation grow until they coalesce. This marks the inception of the persistent stage during which the vegetation cover is predominantly oak–pine forest. Hence the path of succession does not differ from point to point but the rate of succession does. It is argued that the existence of distinct successional stages and the mode of transition between them support the organismal concept of vegetation.

Forest typological and phytososological biodiversity of forest vegetation of Slobozhansky National Park is shown. The park covers 5244 hectares and includes the main parts of the run off valleys of the left-bank Merla River tributary, which belongs to the Vorskla River basin in the Kharkiv region. The main forest-forming species of the Slobozhansky National Nature Park are Pinus sylvestris L. (2779.3 hectares, 59.84%), Quercus robur L. (1451.8 hectares, 31.26%). Minor areas are occupied by Betula pendula Roth (138.3 hectares, 2.98%), Alnus glutinosa (L.) P. Gaertn. (122.5 hectares, 2.64%), Populus tremula L. (45.0 hectares, 0.97%) and other species. Areas covered with forest vegetation are represented by 16 edatopes: all trophotope and almost all hygrotopes, except very dry. Among the trophotopes subors (2015.2 hectares, 43.39%), oak wood (1504.4 hectares, 32.39%) and sugruds (1042.2 hectares, 22.44%) predominate, and the part of pine forest is insignificant (82.5 hectares, 1.78%). Among hygrotopes, the majority are with fresh conditions (4060.6 hectares, 87.43%), much smaller areas are dry (268.4 hectares, 5.78%), damp (184.3 hectares, 3.97%), moist (124.4 hectares, 2.68%) and wet (6.6 hectares, 0.14%) conditions. There are 17 types of forests in the Slobozhansky National Park areas covered with forest vegetation. Fresh oak-pine forest (1780.6 hectares, 38.35%), fresh maple-linden forest (1453.6 hectares, 31.30%), fresh linden-oak-pine sugrud (756.8 hectares, 16.30%) are dominated. Pinus sylvestris plantations grow in 10 forest types. The most common types of pine forests are fresh oak-pine and fresh linden-oak-pine sugrud. Quercus robur growth in 7 forest types, the most common of which is fresh maple-linden oak wood. The distribution of forest typological differences on the territory of the park of vascular plants rare species populations, which have different sozological status is analyzed. Annex I to Resolution 6 of the Berne Convention includes the following species: Dracocephalum ruyschiana L., Jurinea cyanoides (L.) Rchb., Iris pineticola Klokov. A number of species have the appropriate conservation status in Ukraine (Diphasiastrum complanatum (L.) Holub, Lycopodium annotinum L., Dracocephalum ruyschiana, Pulsatilla pratensis (L.) Mill. Sl, Allium ursinum L., Iris furcata M. Bieb., Iris pineticola, Fritillaria meleagris L., F. ruthenica Wikstr., Tulipa quercetorum Klokov & Zoz, Epipactis helleborine (L.) Crantz, Listera ovata (L.) R. Br., Neottia nidus-avis (L.) Rich., Platanthera bifolia (L.) Rich., Stipa borysthenica Klokov ex Prokudin) and 22 species at the regional range.
