Bottomland Forests

Carrying out its assignment Poltava-city green belt bottomland forests with short-term flooding, has significant anthropogenic impact, needs constant research of forest biogeocoenosis present day condition. There have been done the complex research of bottomland forests with short-term flooding which are located in the range of Poltava-city green belt. Forest types according to O. L. Belgard have been noted. Soil and geobotanical characteristics, soil sections macromorphological peculiarities have been given, results of soil water extracts analysis in the investigated forestry have been noted. Throuout the complex researches of all components of forest biogeocoenosis the learning of forest and environment coorelation that is due to anthropogenic effect is topical. Especially it concerns the big cities green belt of industrial regions that suffer from the human direct influence or indirect consequences of his living. Thereby the National special-purpose program «Forests of Ukraine» for 2010–2015 was approved the aim of which is a complex study of this category of forest-steppe zone forest biogeocoenosis. For this reason was made an accent to investigate all-round the Poltava-city green belt forests related to Poltava Region throuout the regional special-purpose program of forestry integrated development «Poltava region forests by 2015». To identify the soil and geobotanical characteristics of biogeocenosis and physical and chemical piculiarities of bottomland forests with short-term flooding adaphotop we will consider the most typical sample plots of different plantations according to its forest stand that grows in relatively identical conditions. Forest areas of Poltava-city green belt belongs to the eastern soil and climatic forest-steppe zone of Poltava Region and is situated in forest-stepp belt of Left bank of Dnipro inside the Dnipro and Donetsk dimple. The most common soils are deep, low humic chernozem and middle clay-loam soil. There are mulch and sandy, agrilloarenaceous soils in river valleys. The picture of exploration area ground structure looks in such a way. The most common ground species of the area is a loess-like clay loam. There are sands observed near the river bed of Vorskla and clay on steep slopes. Soddy-meadow and chernozem-meadow, sandy loam and clay loam soils are involved in the bottomland forests formation. Typical chernozem occupies significant territories, which is formed by herbaceous grouping of mesoxerophytes, euxerophytes and xeromesophytes. Floodplain soils are divided into three parts: riverine, central and terrace near flood plain. In the riverine part is formed the most light mechanical components of interbedding soils formed on new derived silt from slightly humic layers. There are a low percent of humus (not more than 1 %) and nutritional chemicals. Thereby their fertility is low. In the central part of floodplain had been formed the sandy loam and clay loam soils with stronger profile on the massive, often calcareous or carbonaceous parent rock material. In cases of flood the water is widely overflowed and stay for a long time rich in sludge particles. It is the richest soils of the floodplain. The done research gave us the opportunity to clear up that the bottomland forests with short-term flooding of Poltava-city green belt are consist mainly of oak, aspen and alder forests. The formation and distribution of the main associations of floodplain forests depend on the regime of floodplain, trophotop and relief inhomogenuity. It was noticed that it can be found three more typical natural forest vegetations related to bottomland forests with short-term flooding inside the Poltava-city green belt: Dc' 3 (moist linden oak forest with hairlike sedge), Dn / 4 (alder forest with muddy tall herbaceous vegetation), Dc / 2 (live aspen forest with). It was noticed, that in all investigated plant formations the forest site type is sandy loam with different variations: live (SP / 2), moist (SP / 3), muddy (SP / 4). Different variations of soil has been investigated. There is no carbonate in soils of the investigated biogeocenosis. Water extract analysis tell about the lack of salinity properties, dry particles ranges (0,05–0,2 %), pH is alkaline. Detailed soil and geobotanical characteristics and establishing peculiarities of bottomland forests with short-term flooding adaphotop will give opportunity to reconstruct the existing Poltava-city green belt plantations and organize the stationary investigations with the aim of their more rational employment and saving.

The forest site capacity using was quantitatively assessed for the stands of the main forest-forming species of Ukraine, Scots pine and common oak, taking into account natural zones and forest types. The tables of productivity of modal and highly productive pine and oak stands have been developed. It has been found that the stands use an average of 50–75 % of the forest site capacity of lands. The average weighted value of the capacity used by pine forests was 68–76 % in the Polissya zone, 70–78 % and 68–73 % in the Right-bank and Left-bank Forest-Steppe zones respectively, and 54–78 % in the Steppe zone. For oak stands, the value was 71–75 % and 63–71 % for the Right-bank and Left-bank Forest-Steppe zones respectively and 65–75 % for the Steppe zone. The basis for increasing the productivity of forests was confirmed to be the differentiation of forest management systems and individual forestry activities on a zonal and typological basis.

The incidence of ash dieback in the forest-steppe part of Sumy and Kharkiv Regions was analysed taking into account the type of forest site conditions, the stand age, relative stocking density, site index class and the proportion of European ash in the stand composition. Ash dieback is quite widespread in inspected stands of the Left-Bank Forest-Steppe of Sumy and Kharkiv Regions. The disease spreads similarly in natural and artificial stands. It was more often revealed in the fresh fertile forest site conditions, however, such forest site conditions are the most spread and the most favourable for European ash. It was found that ash dieback incidence tends to grow with a stand aging and lasts up to the stand’s age of 80. It can be explained by the development of stem and collar rots which occur later. Ash dieback incidence is the highest in the stands with 40–70 % of ash in their composition, at a relative density of stocking over 0.5 in the stands of different site index classes.

The age structure of European ash stands in the forest fund of ten forest enterprises from Sumy, Kharkiv and Poltava regions was analyzed considering forest site conditions, stand origin, site index and ash proportion in the forest composition. The average age of ash stands is 68 years for the Left-Bank Forest-Steppe. On average from 46.1 % to 81.6% of European ash stands survive up to the V age class. The average age of ash stands is the highest in the forest-steppe part of Sumy Region in D2 and D3, in Kharkiv Region in D1, and in Poltava Region in C2 and C3. The average age is the highest (75 years) in artificial seed stands in Kharkiv Region, in natural seed (86 years) and vegetative (77 years) origin in Sumy Region. The survival of pure and almost pure ash stands is the highest in Kharkiv Region and the lowest in Poltava Region. In the legislatively adopted maturity age (VIII age class) survival of European ash with its proportion of 80–100 % is 26.5 %, 13.1 % and 3.2 % in Kharkiv, Sumy and Poltava Regions respectively. Correction of the main felling age in forests that are possible for exploitation is suggested considering the possible loss of timber quality as a result of forest damage by different causes.

The results of the integrated assessment of prospects for use of Douglas fir (Pseudotsuga Menziesii (Mirb.) Franco) in botanical gardens and arboretums in five regions in the forest-steppe zone of Ukraine are presented. In most cases, there was a fresh fertile forest site type, and in one, there was a dry fertile site. The indicators of growth, stem quality, available seed production and self-seedlings were determined. The comparison was realized with the native species, English oak, which is traditionally grown in the regions in given forest conditions. According to the results of the integrated assessment, Douglas fir in most cases was noted a perspective species in the Ukrainian forest-steppe zone and can be used for the creation of forest plantations, protective stands, and landscaping. The climatic conditions for the regions of the study were different in the average annual rainfall and the Selyaninov’s hydrothermal coefficient.

The taxonomic and ecological composition of the autochthonous land mollusc fauna in different parts of the plain Ukraine was analyzed on the basis of the personal data, collection materials of the State Museum of Natural History of the NAS of Ukraine in Lviv as well as numerous literature sources. Excluding representatives of the genus Helicopsis, the taxonomy and species composition of which in the territory of Ukraine still require clarification, and the steppe part of the Crimean peninsula, in four landscape zones of Ukraine, currently, a total of 109 species of land molluscs, which are autochthonous for at least part of the analyzed territory, are registered. The maximum species diversity (103 species and 2 representatives of the genus Helicopsis) is recorded in the zone of deciduous forests, followed by the right-bank part of the forest-steppe zone. The smallest number of the autochthonous species of land molluscs was noted for the right-bank part of the steppe zone. Within the Ukrainian Polesie and the forest-steppe zone of Ukraine, the taxonomic diversity of land molluscs decreases from west to east. The number of the registered autochthonous species decreases, respectively, by 1.5 and 1.7 times, and the generic diversity by 1.3 and 1.5 times. In the steppe zone, the main centre of the species diversity is the Donetsk Upland, located in the east of the country. In taxonomic and ecological composition, land mollusc complexes of the right-bank part of the forest-steppe zone are closer to the zone of deciduous forests, in its left-bank part – to the left-bank steppe. In general, the spatial differentiation of land mollusc fauna in the plain territories of Ukraine is more strongly associated not with the boundaries of landscaped zones, but with the location of these territories with respect to the Dnieper bed and with some uplands, where the species diversity of land molluscs of the zone of deciduous forests and forest-steppe zone (Podolian Upland) and the steppe zone (Donetsk Upland) is concentrated.

The plot of study is Cheboksary and its suburbans and located on the joint of two landscape zones: a forest zone and a forest-steppe zone. The border between the zones goes along the Volga River, which establishes favourable environment for recreation. There has been observed slope type of areas on the right bank of the Volga River of the Cheboksary and Kuybyshev Reservoir. It has 3º and more incline, with washed-off soil and broadleaved woodland (relict mountainous oak woods), subjected to considerable land-clearing. In the immediate bank zone of the Volga River, where abrasive-soil-slipping and abrasive-talus processes mostly develop, the main types of natural areas have been marked out: 1) Abrasive landslide cliffs at the original slopes of Volga Valley of 60º steepness, more than 15 m high, with permanent watering as a result of underground waters leakage; 2) Abrasive cliffs of terraces above flood-plains of 2 m high; 3) Abrasive cliffs of original slope of the valley of the river Volga of 2 m high, with distinctive abrasive niches in the lower part of the slope or temporary concentration of caving demolishing material. Left coast is lowland plain, the part of taiga landscape zone. Low terraces above flood plain of Volga are formed by sand with loam layers, with sod-podzol sandy and sandy loam soil in combination with marshy soil, with fir-pine forest, with from lichen bogs to sphagnum bog; in lowlands, on old felling plots, on abandoned peat mines deciduous forests with mostly birches and aspens prevail.

Forest Typology

Natural forests have their own ancient history, for this reason, their composition and structure reflect their existing conditions. In the artificial forests, only growth class and plantations general conditions can be in part the indicator of this residence. O. L. Belgard investigated natural biogeocoenosis and artificial cultural geocoenosis and worked up the detailed forest typology. The peculiarity of O. L. Belgard typology is biogeocoenological approach to the understanding and forest investigating based on G. M. Vysotskiy, G. F. Morozov, V. M. Suchkov ideas.  O. L. Belgard accepted the conception of forest biogeocoenosis the components of which are phytocoenosis, zoocoenosis, microbiota, climatope and adaphotope. Rozsoshentsy forestry consists of 87 planning compartments with a total area of 3130.0 hectares, is a part of National Enterprise “Poltava forestry” and is situated on its southern part on the territory of Poltava administrative district and Poltava city. There are no publications in the science literature that could systematically reflect the results of investigations taken place in Rozsoshentsy forest area.  Different scientists in different times investigated particular types of vegetations; the general characteristic of forests was specified in some works. The aim of our work is the forest typology investigation, ecological and biological, typological, soil and geobotanical peculiarities of natural and artificial forests of Rozsoshentsy forest area. For the fist time the investigation of natural and artificial forests of Rozsoshentsy forest area of Poltava-city green belt has been started according to the method of O. L. Belgard forest typology. Groups that were investigated inside the forestry are related to hydrotopes of bottomland forests with long-term flooding, bottomland forests with short-term flooding, noninundated with arena and ravine forests.  The forest type is defined by accessories to specific trophotope and hydrotope and connected with floodplain factor of certain place of existence. The main place in definition of ecotope peculiarities takes vegetations that fully reflect the dimensionality of conditions. There are some plant associations inside the forest type that give an idea about coenosis from the floristic point of view.  One or several associations can correspond to each forest type with direct species structure of tree, bushy and herbaceous layers. Artificial forests typological characteristic based on three taxonomic rank units: forest growth conditions type, ecological structure type and forest stand type. It was found out that the main forest types in structure of investigated forest area are oak, pine, sticky alder and aspen, poplar and birch forests. It means that main forest forming types are six types of wood.  Rozsoshentsy forest area of Poltava-city green belt dendroflora has 33 tree and bushy types, 24 genuses, 14 families, 2 rooms. The most popular forest types on the investigated territory according to the forest typology are new oak and pine trees – 31.9 % , new pine forests – 9.1 %, new and dry maple and linden forests – 27.2 % and 6.3 % correspondently. Forest accounts for 5.3 % of forested areas with excessive wet ground. The investigation that was carried out gave us an opportunity to find out four natural forest vegetation types: (new linden and hornbeam forest with wide grasses), Dn4 (alder forest with moist tall grasses), Dc3 (wet aspen forest with aise-weed), De3 (wet white poplar forest); and two types of artificial forest vegetations: De3 (wet white poplar forest) and AB1 (birch forest with dryish miscellaneous). Different variations of soils have been investigated. It was found out that in investigated natural phytocoenosis the type of forest growth conditions is clay loam with different variations: new (СГ2), wet (СГ3),  moist (СГ4); and wet sandy loam (СП3); in artificial cultural phytocoenosis the sandy loam is wet and dryish. The prevailing soil types on the territory of Rozsoshentsy forestry are dark grey podzolized forest loam, typical chernozem and podzolized hard loamy chernoozem, but in floodplain of the river Vorskla  is a peat-bog soils. The content of humus is 7–8 %. The depth of ground water deposits connected with deposits of brown-red underclay (impermeable horizon) and ranges according to the relief elements and soil degree of erosion from 15 to 34 m. Carbonates are absent in soil of Rozsoshentsy forest area. Water extract analysis tells about the lack of salinity, dry particles ranges between 0.05–0.2 %, PH is mostly alkaline. Detailed ecological and biological characteristics and establishing peculiarities of Rozsoshentsy forest area adaphotope will give an opportunity to reconstruct the existing Poltava-city green belt plantations and organize the stationary investigations with the aim of their employment and saving.
