Also, the greatest value are groups of meadow and shrub steppes, which include rare groups listed in the Green Book of Ukraine, namely the formation of four species of Stipa lessingiana, S. pennata, S. pulcherrima, S. tirsa and Сarexhumilis. The main threats to the existence of the natural complex of this area, which may arise in the event of increased economic impact, are drainage and plowing of floodplains, terracing and reforestation of meadowsteppe slopes of beams.

Forest typological and ecological properties are presented and the representation of natural complexes of the object of the Emerald Network of Ukraine «Dergachivskyi forest» (UA0000283 Dergachivskyi forest) in the territory of the Kharkiv region is covered, it has a total area of 8860.32 hectares. This object is located in the Dergachiv forestry of the State Enterprise «Kharkiv Forest Research Station» in the north-western part of the Kharkiv region. The studied area is a wavy plain with a well-defined valley-beam relief and a developed ravine-beam network. Forest areas covered with forest vegetation are represented by plantations of 24 tree species. The main forestforming tree species Quercus robur (8965.9 hectares, 87.94%); Pinus sylvestris occupies a much smaller area (671.1 hectares, 6.59%). Other tree species occupy minor areas: Betula pendula (128.8 hectares, 1.26%), Tiliacordata (98.8 hectares, 0.97%), Fraxinus excelsior (98.8 hectares, 0.97%), Robinia pseudoacacia (56.1 hectares, 0.55%), Acer platanoides (51.3 hectares, 0.50%) and others. Forest areas covered with forest vegetation are represented by 12 edatopes, covering all trophic groups and moisture levels from dry to moist. The most common types of forest vegetation conditions are fresh (7485.7 hectares, 73.43%) and dry (1922.3 hectares, 18.86%) oak woods. There are 18 forest types in the forest areas covered by forest vegetation, the most common of which are fresh maple-linden oak woods (7485.7 hectares, 73.42%), a slightly smaller area is occupied by dry maple-linden oak woods (1922.3 hectares, 18.86%); much smaller area is occupied by fresh oak-pine forest (496.6 hectares, 4.87%). Quercus robur grows in 6 forest types, the most common of which are fresh (7069.0 hectares, 78.84%) and dry (1882.7 hectares, 21.00%) maplelinden oak woods. Within this area, a number of Emerald forest habitats which are listed in Resolution 4 of the Berne Convention have been identified. So on the bases of the carried-out researches the following settlements of the Emerald network are revealed: E1.71, G1.11, G1.41, G1.A1, G3.4232.

The importance and significance of the conservation of the Emerald Object “The lower part of the Uda River Valley” (UA0000295) in botanical and general ecological aspects is discussed in detail. It is located on the outskirts of Kharkiv with an area of 13,381.0 ha. The studied area combines floodplains of regions occupied by meadows, shrub fragments and forest vegetation, and pine forests with artificial pine plantations. Areas of the loess plateau with arable land and deciduous forests, as well. List of the leading plant species, area's, main ecological and biotic features of identified habitats under Resolution 4 of the Berne Convention, in particular, C1.222, C1.32, C1.33, C3.34, D5.2, E1.2, E2.2, E3.4, F9.1, F3.247, G1.11, G1.21, G1.41, G1.8, G3.4232, G1.A4, G1.A1 for the Emerald Object are presented. The largest areas are occupied by biotops of lowland bogs with sedge and reed thickets without stagnant water (D5.2). There are plain hay fields (E2.2) and wet and moist meadows with a predominance of grasslands (E3.4) and deciduous forests in medium rich and rich soils (G1.A1), fresh and dry forests, and Sarmatian-type forests (G3.4232). The typological diversity of the forest of the territory, the area covered with forest vegetation is 11,585.0 ha, were outlined. Oak (Quercus robur L.) (8,091.5 ha, 69.83%) with a predominance in its plantations of fresh maple-linden oak and Scots pine (Pinus sylvestris L.) (2,529.8 ha, 21.84%) with a predominance of fresh oak-pine sedge are the main forest-forming species. Some species have appropriate conservation status in Ukraine (Botrychium lunaria (L.) SW., Dactylorhiza incarnata (L.) Soo s.l., Epipactis palustris (L.) Crantz, Anacamptis coriophora (L.) R.M. Bateman, Pridgeon & M.W. Chase (Orchis coriophora L.), A. palustris (Jacq.) R.M. Bateman, Pridgeon & M.W. Chase (Orchis palustris Jacq.), and several species are protected at the regional level (Centaurium erythraea Rafn., C. pulchellum (Sw.) Druce, Dianthus stenocalyx Juz., Inula helenium L., Iris pseudacorus L., Filipendula ulmaria (L.) Maxim., Caltha palustris L., Geum rivale L., Parnassia palustris L., Sanguisorba officinalis L., Valeriana officinalis L.)

The current state of biotope’s vegetation cover by natural and spontaneous origin of the Khukhra and Riabyna river valleys was researched, which are left-bank tributaries of the Vorskla river, as fragments of the preserved landscape within one of the western spurs of the Central Russian Upland. They are listed as perspective objects of the Emerald Network — Riabyna river valley in Sumy region (UA0000427) and Khukhra river valley in Sumy region (UA0000429). The obtained new data on environmental significance are data for the primary database formation in the monitoring organization of these territorial objects. The researched areas are mainly floodplains, small segments of pine terraces and slope’s fragments of these rivers native banks. The presence numbers of biotopes from Resolution 4 of the Berne Convention (C1.222; C1.223; C1.224, C1.32; C1.33; C1.4; C2.33; C2.34; C3.51; D5.2; E2.2; E5.4; F9.1; G1.11; G1.21; G1.22; G1.A4; G1.A1) are given for both explored objects, in addition, for the valley of the Riabyna river are indicated E1.3; E3.4, and for the Khukhra river — C3.4; E1.2. We have not confirmed the existence of such biotopes as C3.4, E1.3, C1.4 for these objects. Also, the presence of Sarmatian-type pine forests (G3.4232) was noted, which are timed to the elevations of pine terraces. Biotopes with constant excessive moisture are ubiquitous in the waters of low-flow artificial ponds. Eutrophic and mesotrophic vegetation of slow-flowing waters often occurs in shallow water along riverbeds. Biotopes groups of dwarf annual amphibious plants were observed only in fragments. Lowland swamps with sedge thickets without stagnant water are widespread in the floodplain, although they occupy small areas. Biotopes flooded pasture and hay meadows are a variety of options coenotic (herbaceous and cereal, wet and moist high-grass meadows). Biotopes of riparian shrubs, willow and willow-poplar floodplain forests are distributed in small fragments in the riverbed of floodplains. Mixed riparian floodplain and gallery forests occur in low-lying areas at the transition from the floodplain to the pine terrace. In general, shrub and forest vegetation on the terraces of these rivers are currently quite limited and fragmentary. Due to the reduction in the use of hayfields, in the floodplain the presence of indigenous forest remnants is quite relevant, which should be a source for their restoration in large areas. Important environmental object in these areas, as part of the Emerald Network is the local population of Ostericum palustre, and in the valley of the Khukhra river discovered a large population.
