    Opis:
    The mycorrhizal status of 24 plant species considered as endemic, endangered in Poland and included in the IUCN Red List of Threatened Plants is reported. Selected plants and rhizosphere soil samples were collected in the Tatra Mts (Western Carpathians). Individuals of seriously threatened taxa were obtained from seeds and inoculated with available AM fungal strains under laboratory conditions. AM colonisation was found in 16 plants; 9 species were of the Arum-type, 4 - Paris and 3 taxa revealed intermediate morphology. The mycelium of the fine endophyte (Glomus tenue) and dark septate fungi (DSE) were observed in the material collected in the field. 20 AMF species (Glomeromycota) found in the rhizosphere of the investigated plants were reported for the first time from the Tatra Mts. The results provide information that might be useful for conservation and restoration programmes of these species. Application of AMF in active plant protection projects is discussed.

    Opis:
    Carex disperma Dewey reaches its south-eastern range limit in north-eastern Poland. It has often been confused with Carex loliacea L. In this paper the diagnostic features of both species are presented. A total of about 47 reliable localities of C. disperma were recorded within the present borders of Poland. Less than one-third of them have only been confirmed recently. They are aggregated in large forest complexes in north-eastern Poland (Romincka, Białowieża, Borki, Augustów and Knyszyn Forests). A list of localities of C. disperma based on herbarium records, credible literature data and the author's own data is provided, as well as maps of distribution of both C. disperma and C. loliacea in Poland. The existence of C. disperma × C. loliacea hybrid was not confirmed. Considering the number of localities, dynamics and population sizes of both species it is clear that C. disperma is a species with higher conservation value than C. loliacea. Unlike C. disperma, the latter species is not threatened with extinction in Poland. The resources of C. disperma are very limited and the species needs conservation measures such as creating sufficiently large nature reserves where appropriate hydrological conditions can be maintained.

    Opis:
    We present a study of the distribution, ecology and conservation status of Cupressus atlantica, an endemic tree of the High Atlas (Morocco). The main populations of this species grow in a reduced area along the N’Fiss valley in the Central High Atlas and are gradually receding. Particular populations are increasingly fragmented and the total area covered by the cypress woodland has decreased to less than a third of the surface occupied in the 1930s. Overgrazing reduces the woodlands’ regenerative capacity, and the exploitation of the wood, linked to traditional uses by the rural society of the N’Fiss valley, directly reduces the number of trees. Great efforts being made to protect the species by the Haut Commissariat aux Eaux et Forêts are having some effect in recent years.

    Opis:
    Continuous monitoring of the size of wildlife population is a basic requirement for proper wildlife management. Therefore, this study assesses the conservation status of Roan antelope in Old Oyo National Park. A reconnaissance survey was carried out to the park to determine the areas of concentration of Roan antelope. The study was carried out for four months (March-June, 2018) using line transect method and direct sighting. The data collected were analyzed using descriptive statistics. The study revealed that the highest population of 34 individuals of roan antelope was recorded in the month of March, while the least population of the roan antelope was 8 in the month of July. Marguba range has the highest percentage of 28.2%, followed by Oyo-Ile with the population of 27%, while Sepeteri and Tede has the population of 22.4% respectively. The population structure of Roan indicates that the female roan antelope had the highest population of 35, followed by the young ones with the population of 27, while the male has the least number of observation of 23. The vegetation distribution revealed that Riparian forest vegetation zone has the highest number of individual with 24 observation, follow by Isoberlina doka (23) while Diospyrus mespillisformis and Afzelia africana recorded 19 respectively. The population of roan antelope could then build up to sustain the effective breeding population size. Uncontrolled burning activities by poachers and variations in seasons changed the habitat of Roan Antelope and this has threatened most of the plant species that provide shelter and food for the animals. It was therefore recommended that the vegetation types should be protected from adverse late burning by poachers as this is necessary for saving the vegetation for dry season feeding of roan antelope.

    Opis:
    The habitat 1110 ‘Sandbanks that are slightly covered by sea water all the time’ is protected in 766 Natura 2000 sites in Europe. Due to its significant structural and functional diversity in particular European countries, there is a necessity of working out specific site indices for the state assessment. Methodology of the monitoring and assessment of habitats from Annex I, II, IV, and V of Habitat’s Directive is gradually expanding; therefore, the first assessment of the state of 1110 habitat in Poland was an expert judgement. The aim of this work was the presentation of methods used in the ‘Sandbanks that are slightly covered by sea water all the time’ state assessment in selected European countries and presentation of the assumptions for the assessment in Poland. This paper is a continuation of the series concerning marine habitats assessment issue. The first article focused on habitat 1160 ‘Large, shallow inlets and bays’.

Ze względu na znaczne zróżnicowanie strukturalne i funkcjonalne siedliska w poszczególnych rejonach istnieje konieczność wypracowania specyficznych dla danego regionu wskaźników do jego oceny. Metodyki monitoringu siedlisk i gatunków z załączników I, II, IV i V Dyrektywy siedliskowej są stale uzupełniane, jednak w Polsce dotychczasowa ocena siedliska 1110 była oceną ekspercką. Celem pracy jest prezentacja kryteriów stosowanych do oceny stanu siedliska 1110 w wybranych krajach oraz przedstawienie ogólnych założeń do przeprowadzenia takiej oceny w miejscach występowania tego siedliska w Polsce. Niniejsza praca stanowi kontynuację cyklu artykułów dotyczącego metodyk oceny stanu siedlisk morskich. Pierwszy artykuł został poświęcony siedlisku 1160 ‘Duże i płytkie zatoki’.

    Opis:
    Planning effective conservation measures in relation to particular habitats and species, which are the subjects of protection, require, above all, assessing their conservation status and identifying factors that have influenced this state. Although the scope of monitoring and the number of investigated species and habitats from Annex I, II, IV and V of the Habitats Directive is gradually increasing, no formal assessment of 1160 habitat has been performed so far. Methodological guidelines don’t include any assumptions to investigation and valuation of this habitat. In Europe the habitat 1160 is protected in 462 Natura 2000 sites. Due to its significant structural and functional diversity in particular European countries, there is a necessity of working out specific site indices for the state assessment. The aim of this work was the review of methods used in the ‘Large, shallow inlets and bays’ state assessment in selected European countries and presentation the assumptions for the assessment in Polish special area of conservation: PLH220032 Puck Bay and Hel Peninsula.

    Opis:
    Dionysia involucrata Zaprjag. (Primulaceae) is known as critically endangered endemic species of Hissar Mountains in Tajikistan. It is reported from few localities mainly in Varzob River valley and its tributaries. The species inhabits steep or overhanging faces of granite rocks in narrow river gorges. During the research all known populations of D. involucrata were examined in respect of the habitat conditions and species composition of vegetation plots. We analyzed the population extent of the species in its range in Tajikistan and the main threats in order to assess its conservation status. The detrended correspondence analysis was performed on a matrix of 65 relevés and 49 species (vascular plants and mosses), to classify the phytocoenosis with domination of D. involucrata according to their floristic composition in relation to other petrophytic vegetation units. Using our field data regarding present extent of occurrence and area of occupancy we conclude that the threat category of D. involucrata should be reassessed from critically endangered to endangered. The species shows decline tendency in extent of occurrence, area of occupancy as well as in number of locations. The vegetation plots with domination of D. involucrata have relatively high level of separateness due to different species composition. We define the new association – Dionysietum involucratae – representing chasmophytic vegetation of submontane and montane zone in Middle Asia (ca. 1000–1600 m a.s.l.). The plots of Dionysietum involucratae were found mainly on granite rocks, on very steep or overhanging faces, on southwestern or southern exposition. The association is rather poor in species with inconsiderable contribution of mosses. Despite the diagnostic species, Campanula incanescens, Carex koshewnikowii and Scutellaria hissarica were the most abundant and frequent taxa within the researched patches of vegetation.

    Opis:
    The material heritage of the Great Poland village should be considered inseparable with the spiritual values. That what is now characteristic for Greater Poland is the result of the centuries-old processes. This is apparent both in the settlement, construction, customs, folklore and cooking. The settlement landscape of Greater Poland was shaped by the medieval settlement, the rise of the feudal manor, various colonization actions from the XVII to the XIX century, including the Olęder settlement, the activity of the Prussian Commission for Settlement. In the XIX century processes of enfranchisement in the form of pooling, separation, and parceling and the industrial development have led to reconstruction of the village. The land reform in the interwar period, from 1925 and the PKWN decree on agricultural reform of 1944 have completed the changes. The clear imprint in all areas of life left the boundary of partition, which divided for over 100 years the homogeneous body which was Greater Poland. Differences between the parts of Greater Poland belonging to the Prussian and Russian partition despite the passage of more than 90 years, are still visible. The rural heritage of Greater Poland is preserved in the spatial configurations, with gables of houses set to the rural road, especially in the southwestern Greater Poland. It's also still the readable Olęder settlement, in the Nadnoteckie areas (marsh lanes - Polish rzędówki bagienne), and in the vicinity of Nowy Tomyśl, Lwówek and Trzciel (the dispersed settlement) and in the Pyzdrska Forest (river floodplains on the Warta and Prosna). Great Poland can boast a very large amount of preserved palaces, mansions, residences, parks and farms. Many of them represent a high artistic, architectural and spatial composition level. The dense settlement network which was already during the Middle Ages caused that there are in Greater Poland a lot of churches, both brick and timber and half-timbered churches, often very valuable. The agricultural landscape is characterized by windmills, mills, sugar mills, distilleries. Monuments of the railways are also noteworthy. Many objects are individually protected by registration in the register of monuments. Only 9 ruralistic formations in the region are listed in the register of monuments. Only 1 cultural park around of Żerków and Śmiełów was established until now. It is necessary to mention the numerous risks, the unfavorable changes which are taking place in a village in the last 20 years. There are also many positive aspects of 145 numerous operations. Just even to mention the Local Action Groups, Village Renewal movement, the Culinary Heritage network, various folk festivals associated with traditional food, etc. This article outlined only in a summary form the problems of an extremely rich and diverse heritage of the village of Great Poland.

    Opis:
    Taxus baccata L. is a rare species threatenedwith extinction in Greece, as in other parts of Europe. This paper deals with the ecological status of the species in the area of NE Chalkidiki northern Greece, where the species appears in one of the greatest populations of the country. Site, standand yew population characteristics were studied in the area that species occupies. Eleven sample plots were marked, and on each plot, the height and diameter at breast height (DBH) were measured for all yew trees, as well as for all the individuals of the rest tree species, with diameter at breast height greater than 4 cm. Tree vitality of all trees was also estimated according to IUFRO classification. Yew radial growth was studied using tree-ring analysis. Tree natural regeneration was investigated within subplots of different dimensions and according to two height classes. Results showed that yew population occurs in stands dominated by beech, presenting a mean density of 301 trees per hectare, with a total population of 430 trees with DBH above 4 cm. It forms the secondary stand, and dominates in the stand understorey, accompanied with Fagus sylvatica and Ilex aquifolium, while it appears rarely in the overstorey. Yew tree vitality was foundto be quite high, and significantly higher than that of beech. Radial growth of the sampled trees follows a slow and constant annual increment gradually decreasing by tree age. Yew natural regeneration was foundto be relatively low, 1341.8 individuals (seedlings and saplings up to 1 m) per hectare. Management and in situ conservation of the species in the area should focus on species protection measures, andon specific silvicultural treatments for creating favourable conditions for species growth.

    Opis:
    In the mountains of the north-central Sicily (Italy), a small and isolated population of Sicilian fir (Abies nebrodensis) has survived to the present day. It is the most unique species of the Sicilian flora, not only because of its taxonomic position, but mostly because of its endemic and relict status and the serious risk of extinction. The single natural population of this extremely rare species is currently represented by only 30 mature individuals scattered over a small area in the Madonie Mountains. This species has experienced intensive population decline since the end of the 17th century, and its situation became extremely critical in the first decades of the 19th century due to deforestation and overgrazing. Consequently, Sicilian fir was considered to be extinct about three decades before being rediscovered on the Madonie Mts. in 1937. Sicilian fir is recognized as one of the most endangered coniferous species in the world. It is classified as critically endangered by IUCN, and also included in the list of 50 most endangered plant species in the Mediterranean region. Currently, the limited population size, a small proportion of reproductive individuals, habitat loss, ongoing and projected climate change, and hybridization with other species pose serious threats to survival of this species. Therefore, it is extremely important to maintain actions focusing on in situ and ex situ conservation in order to preserve and protect the existing resources of Sicilian fir, which represents the natural heritage unique to the Mediterranean.
