Abstract Population-based studies of endangered plant species are key methods for assessment of the status for these plants at any territory. Plant species of the Orchidaceae family are sensitive components in natural ecosystems. That is why determination of the status for their populations can be considered as indicators for the status of natural ecosystem position as a whole. Investigations of three Orchidaceae species populations (Orchis militaris L., Epipactis palustris (L.) Crantz, Malaxis monophyllos (L.) Swartz) were carried out in Central Russia (Republic of Mordovia). Abundance, density, structure and dynamics of populations of these species were studied. Species composition of accompanying flora was established for each rare species. Some morphometrical parameters of individuals for the studied species were measured. Features of ontogenetic spectrum for Orchis militaris and Epipactis palustris populations were shown.

Awned sedge (Carex atherodes Spreng.) fertilized with 224 kg/ha 16-20-0 plus 112 kg/ha 0-0-60 in shallow water over clay soil in May 1972 and on wet ground on the same plots in October 1972 was not different from controls in yield or chemical composition in 1972 or 1973. All yields in 1973 were less than from corresponding treatments on the same plots in 1972. Plots mowed once and twice each year averaged about 7,500 kg/ha forage, 620 kg/ha protein per year compared with 3,000 kg/ha forage and 520 kg/ha protein for six mowings from late May or early June to September. The latter, however, produced only about one third as much forage in 1973 as in 1972, though its chemical quality either did not decline or tended to increase during the season. Protein and P percentage in first cuttings declined from May to September. There was little change in Ca. Near-maximum fibre content occurred by late June in undisturbed sedge. Analytical data compared favorably with those reported for upland or meadow grasses. On balance, two mowings per year seemed optimum regarding yield and chemical composition. More frequent cuttings soon weakened the stand and therefore apparently would be desirable only as preparation for introduction of other hay, or other cover for wildlife or for elimination of lake margin growth.

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.)

Abstract A description is provided for Anthracoidea intercedens, an ovariicolous smut of Carex species causing destruction of ovaries. Some information on its dispersal and transmission and conservation status is given, along with details of its geographical distribution (Asia: China, (Heilongjiang), Russia (Far East, Kamchatka region, Uda region, Ussuri region, Zeya-Bureya region), Europe: Finland, Hungary, Lithuania, Norway, Poland, Russia (Karelian-Murmansk region), Sweden) and hosts (Carex atherodes, C. drymophila, C. lasiocarpa (principal host), C. sordida, C. gotoi (C. songorica subsp. gotoi) and C. rhynchophysa).


The long-term floristic research in the City of Kharkiv, as well as analysis of the literature data and CWU herbarium materials recorded 95 species, 65 genera and 38 families of plants in the present water and wetland flora of the city. Of these, 18 species occur in the water bodies, and 77 species in the wetlands. An annotated list of the water and wetland flora is compiled. All species are provided with the data on their distribution within the city, habitat conditions, types of geographic range and conservation status. Geographical analysis revealed the general correspondence of the city flora to the typical flora of the region. The city flora is represented by the groups of species with five regional types; the Circumpolar (35 species, 36.8 %) and the Eurasian (26 species, 27.3 %) types are the most speciose. In terms of conservation importance, 15 recorded species require protection ‒ two species of water vascular plants and 13 species of wetlands. Of these, four species are listed in the Red Data Book of Ukraine (Anacamptis coriophora, Anacamptis palustris, Dactylorchiza majalis, Epipactis palustris); seven species are in the list of plants that require special protection in the Kharkiv Region (Carex pseudocyperus, Nuphar luteum, Parnassia palustris, Ranunculus circinatum, Typha laxmannii, Valeriana officinalis, Vallisneria spiralis); three species are listed in Annex II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES II) (Anacamptis coriophora, Anacamptis palustris, Epipactis palustris); one species (Epipactis palustris) is in the list of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES); and two species are in the Red List of Macrophytes (Nuphar lutea and Glyceria arundinacea). One species is also a member of а plant association listed in the Green Data Book of Ukraine, and two species are the members of vegetation groups in the Green List of Kharkiv Region. Five invasive species were found in the city flora: three water species (Pistia stratiotes, Vallisneria spiralis, Elodea canadensis) and two wetland species (Echinocistis lobata and Bidens frondosa).
