The article presents the results of the research of recreational and health stands in Kremenets district of Ternopil region. The total area of these forests is 5868.2 hectares. Studies of the typological structure of the forests were carried out according to the methods of AlekseevPohrebniak Forest Typology of Forestry Ecological School. MapInfo Professional 12.0 and a vector map of Ukraine were used to construct a map-scheme of the research region. The typological variety of recreational and health-improving stands is represented from subors (В) to dubravas (D). Thus, dubravas are the largest share among them (72.9% of the total area covered with forest vegetation). The share of the area of sudubravas is 17.7% of the total area covered with forest vegetation; the rest is subors (9.4%). Forest managers have identified 14 types of forests on the territory of the research facility. Thus, there are only 2 types of forest in the subors, 8 types of forest in the sudubravas and 4 types of forests in the dubravas. The most common type of forest in Kremenets district is fresh hornbeam forest represented 71.6% of the total area covered with forest vegetation. The share of fresh hornbeam-oak-pine forest reaches 17.1%; a slightly smaller share is represented by fresh oak-pine subors — 9.4%. The forest species diversity is represented by 22 species of trees. Thus, among these tree species, the largest area is occupied by Common Oak (Quercus robur L.) — 40.6% of the total area covered with forest vegetation, and 29.1% — by Scots Pine (Pinus sylvestris L.). Stands of artificial origin (78.0% of the total area covered with forest vegetation) are dominant; the rest of stands have natural origin (22.0%). The age structure of stands is unbalanced. Middle-aged stands dominate (57.9% of the total area covered with forest vegetation). The share of maturing, young and matured forests ranges from 9.0 to 14.9% of the total forest area. In terms of relative completeness, stands with a density of 0.71–0.8 dominate which is 37.7% of the total area covered with forest vegetation. The share of stands with completeness of 0.61–0.7 (29.9%) and 0.81–0.9 (14.5%) is slightly smaller. The bonitete classes are dominated by stands of the I bonitete class — 51.3% of the total area covered with forest vegetation. Thus, the share of II, Ia and III bonitete classes varies from 7.1 to 23.3% of the total forest area

The paper presents the findings of a study of species diversity of forests in the Kharkivska Oblast. The study was conducted on the territory of ten forestry enterprises and the State Enterprise Kharkiv Forest Research Station and the Homilsha Woods National Nature Park on an area of 282.3 thousand ha (area is subordinated to the State Forest Resources Agency of Ukraine). The purpose of the study was to analyse the species diversity and typological structure of forests in the Kharkivska Oblast. The study of species diversity was carried out based on analysis of the subcompartment database of the VO Ukrderzhlisproekt. The plantations were classified by the trophotope on the territory of the research facility in accordance with the main methodological provisions of the Ukrainian forestry and forest typology. A diagrammatic map of forests and dominant species (common oak and Scots pine) was compiled using the MapInfo Professional 12.5 software package and a vector map of 12 forestries in the Kharkivska Oblast. It has been established that 56 species of trees grow in the Kharkivska Oblast. Among these tree species, the predominant ones are common oak (53.4%) and Scots pine (32.7%). The distribution of plantations by trophotope is characterised by certain features. For example, dubrava conditions prevail in the stands (65.6% of the total area covered by forest vegetation), subor forests are 3.5 times less represented, and sudubravas and pine forests are the least common. Among the forest types, the most common are fresh maple-linden dubravas (43.7%) and fresh oak-pine subors (18.9%). The practical significance of the study is that the analysis of species diversity and typological structure of forests must be taken into account during the planning, organisation, and conduct of forestry activities in the Kharkivska Oblast

Where nature protection is concerned, the expert assessment of an environment poses questions about its natural and cultural heritage and its potential, about how representative it may be, about biodiversity in all its facets and about its development or potential threats to its existence. Although the forest was the dominant habitat in the original natural European landscape, for a long time nature protection has devoted too little attention to it. There are diverse threats and deficiencies. However, in the Swiss forests positive developments are discernible. Thus nature protection is one of the basic functions of the forest, nature reserves are being created, the area of the forest is increasing, as are reserves of deadwood, and greater importance is being given to regeneration suited to the site. Nevertheless much remains to be done to really achieve the goal of biodiversity and sus-tainability. For this purpose segregative and integrative measures are required. Since diversity needs surface area, in the first place it must be possible to set aside as forest reserves a quarter of the total forest area, spread over the whole country and preferably as natural forest reserves, in order to start the process of a long-term restoration to the natural state. Here the conservation of natural self-regulating processes supersedes classical nature protection. With a series of further integrative measures, biodiversity must also be promoted over the whole remaining forest area and in the areas of transition to other habitats. An abundance of varied structures is the key to diversity of species. A more courageous attitude to wilderness and “untidiness” when dealing with the forest is to be recommended. Nature experiences in wilderness areas give the population the possibility of discovering diversity and natural processes and encourage respect for the innumerable other species and habitats.

The diversity of mangrove vegetation is a community that has different characteristics from other communities. Diversity is an important component in mangrove management, but so far the availability of data related to mangroves is still very minimal, including those related to the species diversity of mangrove forest vegetation in the region. This study aims to obtain data on species diversity of vegetation found in the mangrove forest area of Dusun Besar Village, Pulau Maya District, Kayong Utara Regency. Method used was a combination of path and plot method, and the determination of the location and research path location were carried out using purposive sampling. The results of observation and data analysis showed that the dominant vegetation species with the highest importance value index (INP) for seedlings, saplings and trees was the Avicennia marina, namely the INP value of seedlings 37.04%, the INP values of sapling 65.24%, and the value of INP a tree rate of 65. Based on the results of the most dominant analysis found the species of  Avicennia marina with a value of C = 0.03430 for seedling, C = 0.04729 for sapling, and C = 0.04736 for tree level. The diversity of mangrove forest vegetation species in Dusun Besar Village for seedlings, saplings and trees is low because it has an H 'value <1, and the abundance of mangrove vegetation species was not evenly distributed in each forest area because it only has an e value <1.Keywords: Dusun Besar Village, Mangrove Forest, Species Diversity

AbstractPollen is the main food for honeybee broods and young workers and so colony development and reproduction rely heavily on pollen availability, both spatially and temporally, in the environment. Intensification of agriculture and climate seasonality are known to alter honeybee foraging patterns and pollen intake through changes in resource availability in temperate regions; however, little is known about how honeybees respond to such environmental factors in tropical regions.Pollen species collected by honeybees in a Neotropical agricultural region of Colombia were identified. The effects of landscape structure (landscape Shannon Diversity Index, forest area in 1000 m around the apiary) and climate seasonality (mean monthly precipitation) on the amount, richness and diversity of pollen collected by the honeybees were evaluated for all pollen species together and pollen species segregated according to forest and anthropic areas (croplands, grasslands, woodlands, urban areas).Honeybees were found to be much more associated with anthropic than forest pollen species regardless of landscape structure or precipitation. However, the amount, richness and diversity of pollen from all species and forest species responded positively to landscape diversity and forest area, suggesting an advantage for honeybees in obtaining small quantities of pollen from forest species, in spite of being well-adapted to forage in anthropic areas. Precipitation was found not to be related to the overall amount and overall richness of pollen collected by honeybees, suggesting that climate seasonality was not an important factor for pollen foraging. Nonetheless, overall pollen diversity was negatively affected by precipitation in less diverse landscapes, while anthropic pollen diversity was negatively affected in more forested landscapes. These findings are compared with those from temperate regions, and the implications for honeybee productivity and survival, and their interactions with Neotropical native species, are discussed.

Biodiversity is important for maintaining of forest ecosystems functioning and in their resistance to anthropo-climatic challenges. Assessment of species diversity and species ecomorphic analysis is the basis for determining their current status, rational use and protection. At the end of the nineteenth century, Belgard A. L. (1950) in his system of ectomorphs using terminology presented by Dekandol (1956) and Warming (1903), had proposed a «trophomorph» category that reflected species relation to soil richness. Analysis of trophomorphs reflects diversity of soil conditions in different biotopes within forest ecosystems. The article gives an analysis on vascular plant trophomorphs distribution in various forest biotopes of Oril river valley. Flora and vegetation surveys in forests of Oril river valley were carried out by A. L. Belgard and T. F. Kirichenko since the 30s of the 20th century. The latest data on forest vegetation state within the Oril river valley were given in the works of Y. Gamulja and V. Manyuk. Generalized bioecological analysis of flora Oril river valley was represented in the monograph of B. Baranovsky, V. Maniuk, I. Ivanko, L. Karmyzova «Flora analysis of the Oril National Park». As is known, edaphic conditions of plant habitats in a first place are determined by soil fertility depending on the plant nutrients availability. Soddy-forest soil on sandy terrace of Oril river valley has a relatively low content of humus and total nitrogen: 2 and 0.04 %. Under these conditions, pine phytocenoses were ocсurred that represented exclusively by artificial plantings. Soils in the depressed area of Oril river floodplain are much richer in humus and nitrogen content (10 and 0.37 %). Here, arboreal and shrubby vegetation is represented by communities with common oak. On the second terrace of Oril river valley, forest vegetation is represented by artificial pine forests. Microcenoses with black locust, amorpha and willow occurred on elevated areas of sandy terrace (arena). In the depressed area of the arena, microcenoses with aspen and birch, aspen, Tatarian maple, amorpha, black locust were occurred additionally to pine communities. In the Oril floodplain, native arboreal and shrubby vegetation is represented mainly by communities with common oak. In depressed areas of the floodplain, microcenoses with white poplar, black poplar, aspen, Tatarian maple, amorpha, willow (Salix alba, S. fragilis), osiery (Salix cinerea, S. triandra),  and alder are fragmentarily occurred. In conditions of elevated areas of the floodplain, 196 vascular plants species were found, and 105 species in depressed areas. On the second terrace, 38 plant species grow on the elevated areas, and 54 species on the depressed ones. Flora includes 45 adventive plant species. In depressed floodplain areas, oligotrophs are represented by 7 species, mesotrophs by 126 species, megatrophs by 50 species, and in elevated areas: 7, 126 and 25 species, respectively. In depressed areas of arena oligotrophs are represented by 4 species, mesotrophs by 29 species, and megatrophs by 11, elevated areas: 7 and 21 species respectively, and megatrophs were absent.

Oak forests occupy relatively small area of about 1 % (seed origin - less than 0.4 %) of the total forest area in Russia, which continues to decline steadily. The problem of restoring sustainable oak forests of seed origin is one of the most painful. In Shipov forest of Voronezh region from 1875 to 1950 15.1 thousand hectares of crops was created, of which only about 2 hectares survived, the vast majority died or it is a small admixture in stands of natural origin.

Abstract • Key message The aim of the study was to distinguish orchards from other lands with forest vegetation based on the data from airborne laser scanning. The methods based on granulometry provided better results than the pattern analysis. The analysis based on the Forest Data Bank/Cadastre polygons provided better results than the analysis based on the segmentation polygons. Classification of orchards and other areas with forest vegetation is important in the context of reporting forest area to international organizations, forest management, and mitigating effects of climate change. • Context Agricultural lands with forest vegetation, e.g., orchards, do not constitute forests according to the forest definition formulated by the national and international definitions, but contrary to the one formulated in the Kyoto Protocol. It is a reason for the inconsistency in the forest area reported by individual countries. • Aims The aim of the study was to distinguish orchards from other lands with forest vegetation based on the data from airborne laser scanning. • Methods The study analyzed the usefulness of various laser scanning products and the various features of pattern and granulometric analysis in the Milicz forest district in Poland. • Results The methods based on granulometry provided better results than the pattern analysis. The analysis based on the Forest Data Bank/Cadastre polygons provided better results than the analysis based on the segmentation polygons. • Conclusion Granulometric analysis has proved to be a useful tool in the classification of orchards and other areas with forest vegetation. It is important in the context of reporting forest area to international organizations, forest management, and mitigating effects of climate change.

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.

The study aims to assess the scale of forest loss (mostly caused by logging) on breeding sites of the local Black Stork breeding population in the Rivne region of Ukraine, within the Polissia nature zone. The study is based on a GIS analysis of the Global Forest Watch data in intersection of circular buffers of different sizes around 141 Black Stork nests. Forest logging was detected on 38,3% of breeding sites in the region, in 100 m buffers around nests. On more than 14% of breeding territories (in 100 m buffers) forest loss exceeded 20% of the total forest area. Therefore, logging is one of the major threats for the local Black Stork population. The method used for the forest loss detection by a GIS analysis seems to be effective for the search of territories with the violation of protection regime for rare birds when resources are limited.

Summarization of the potential of introskeletal erosion (ISE) was done on the basis of field surveys in the &Scaron;umava Mts., Krkono&scaron;e Mts. and Jesen&iacute;ky Mts. areas. The results give a rough estimation of the ISE extent in mountain forests of the Czech Republic. They indicate that in the mountainous areas of the Czech Republic there are 46,535 ha of forest lands endangered by these processes, which represents 10.1% of mountain forests and 1.7% of the total forest area in the country. The worst situation is in the Krkono&scaron;e Mts., where the considerable ISE potential is on 30.5% of forest area (in the Jesen&iacute;ky Mts. 16.6%, in the Novohradsk&eacute; hory Mts. 13.3%, in the &Scaron;umava&nbsp; Mts. 8.2%). Because these areas are relevant production and water protection areas, the ISE processes have to be studied carefully and forest lands have to be protected, also using special technologies for forest protection and restoration. &nbsp;
