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:
The aim of this study was to provide a phytosociological and ecological characterization of meadow communities in the Łąki w Komborni Natura 2000 site (SE Poland), assess the trends in their transformation, and indicate the major threats impacting on their conservation. The study was conducted in 2015–2016. Three types of meadow communities were distinguished (alliances Molinion, Arrhenatherion, Filipendulion), due to the absence of the species characteristic for associations. The species richness noted per relevé differed significantly between the types of meadows (Kruskal–Wallis test: H = 21.65, p < 0.05). The highest floristic biodiversity (H' = 2.99) was noted for the meadow patches classified as in the Molinion alliance and the lowest (H' = 2.50) was found for the patches from the Filipendulion alliance. Mean values of the ecological indicators (F, R, N) differed between the meadow communities. The greatest disparity was noted for the mean values of the soil moisture indicator (from 6.42 to 7.45). Patches classified in the Filipendulion alliance were developed on the wettest soil substratum, whereas the patches classified in the Arrhenatherion alliance were predominant on a relatively dry substratum. The abandonment of traditional management practices (grazing, mowing) has contributed to transformation of the Molinia meadows, disappearance of characteristic species and succession of shrubs. The Molinia meadow habitat should be conserved by improvement of protection measures (appropriate mowing regime and removal of biomass) to conserve a high species richness and the rare and protected plant species.
Celem pracy była charakterystyka fitosocjologiczna i ekologiczna zbiorowisk łąkowych na obszarze Natura 2000 Łąki w Komborni (SE Polska) oraz ocena kierunków zmian wraz ze wskazaniem głównych zagrożeń. Badania przeprowadzono w latach 2015–2016. W kompleksie wyróżniono trzy typy zbiorowisk, które ze względu na brak gatunków charakterystycznych dla zespołów oraz znaczne przekształcenia fitocenoz podano w randze związku (Molinion, Arrhenatherion, Filipendulion). Zbiorowiska różniły się bogactwem gatunkowym (H = 21.65, p < 0.05). Najwyższą bioróżnorodność florystyczną (H' = 2.99) miały płaty ze związku Molinion, a najniższą (H' = 2.50) ze związku Filipendulion. Średnie wartości wskaźników ekologicznych (F, R, N) były różne dla wydzielonych zbiorowisk. Największe różnice zanotowano w średnich wartościach wskaźnika wilgotności gleby (od 6.42 do 7.45). Na podłożu najbardziej wilgotnym dominowo zbiorowisko z Filipendulion, a na stosunkowo suchym zbiorowisko z Arrhenaterion. Brak tradycyjnego użytkowania (wypas, koszenie) spowodowało przekształcanie łąk trzęślicowych, zanik gatunków charakterystycznych oraz postępujący proces sukcesji. Z uwagi na duże bogactwo gatunkowe, obecność rzadkich i chronionych taksonów istnieje potrzeba zachowania siedliska łąk trzęślicowych na badanym terenie wraz z koniecznością wprowadzenia zabiegów ochronnych (koszenie, usuwanie biomasy).

Opis:
Badania terenowe przeprowadzono metodą kartogramu w latach 1997-2005 na obszarze Ińskiego Parku Krajobrazowego. Przedmiotem badań były rośliny naczyniowe z następujących grup syntaksonomicznych: Lemnetea minoris, Isoëto-Nanojuncetea, Potametea, Littorelletea uniflorae, Phragmitetea, Scheuchzerio-Caricetea nigrae i Oxycocco-Sphagnetea. Celem pracy było przedstawienie aktualnego stanu flory roślin naczyniowych na siedliskach torfowiskowych i wodnych oraz omówienie zagrożeń i problemów związanych z ochroną flory. Na podstawie przeprowadzonych badań oraz w wyniku analizy materiałów literaturowych ustalono listę 141 gatunków roślin naczyniowych. Po raz pierwszy odnotowano występowanie 11 gatunków, natomiast 17 taksonów uznano za wymarłe lub zaginione. Zaobserwowano proces ubożenia flory Parku, związany z negatywną presją człowieka. Na podstawie zamieszczonych w niniejszej pracy wyników można wskazać rejony występowania rzadkich i zagrożonych gatunków roślin oraz cenne pod względem florystycznym obszary, które powinny zostać objęte ochroną prawną.
Field studies based on the cartogramme method were carried out in the Ińsko Landscape Park in 1997-2005. The study was focussed on vascular plants representing the following syntaxonomic groups: Lemnetea minoris, Isoëto-Nanojuncetea, Potametea, Littorelletea uniflorae, Phragmitetea, Scheuchzerio-Caricetea nigrae and Oxycocco-Sphagnetea. The study was aimed at presenting the current status of the vascular plant flora in peatland and aquatic sites, and at discussing threats and problems related to protection of the Park’s flora. Based on results of the study and the analysis of available literature a list of 141 vascular plant species was established. The presence of 11 species was recorded for the first time, while 17 taxa proved extinct or lost. The progress of floral impoverishment was observed in the Park due to the adverse anthropogenic impact. Presented results indicate areas supporting rare and endangered plant species as well as floristically valuable areas which should be granted legal protection.

W artykule omówiono zmiany w stanie zachowania wybranego zbioru materiałów rękopiśmiennych wchodzących w skład Archiwum Księży Zmartwychwstańców w Rzymie. Pokazano zniszczenia wywołane na skutek procesów starzeniowych papieru, wilgoci, owadów i grzybów pleśniowych. Zwrócono też uwagę na inne czynniki związane z użytkowaniem dokumentów w okresie ich powstania: niekorzystnych zdarzeń losowych i przechowywania w niewłaściwych warunkach. Ręczny zapis przekazu treściowego na podłożu papierowym stanowi dla historyków i badaczy przeszłości niewyczerpalne źródło informacji, podjęto więc działania, których celem była próba zdiagnozowania negatywnych zmian w stanie zachowania i wyeliminowania widocznych zagrożeń oraz wytypowanie tych elementów zasobu, które wymagają profesjonalnych prac konserwatorskich.
Il documento affronta i cambiamenti nello stato di conservazione di una raccolta selettiva di materiali manoscritti appartenenti all’Archivio dei Padri Resurrezionisti di Roma. Vengono mostrati i danni causati dall’invecchiamento della carta, dall’umidità, dagli insetti e dai processi di ammuffimento. L’attenzione è stata rivolta anche ad altri fattori legati all’uso dei documenti durante il periodo di provenienza: eventi fisici avversi e conservazione in condizioni inadeguate. La registrazione manoscritta del messaggio su carta è una fonte di informazione indispensabile per gli storici e i ricercatori del passato, pertanto sono state adottate misure per cercare di diagnosticare i cambiamenti negativi nello stato di conservazione ed eliminare le minacce visibili, oltre a selezionare gli elementi della fonte che richiedono un lavoro di conservazione professionale.
The paper addresses changes in the state of preservation of a selected collection of manuscript materials belonging to the Archive of the Resurrectionist Fathers in Rome. The damage caused by the aging of paper, moisture, insects and mold processes has been shown. The attention was also paid to other factors related to the use of documents during the period of their origin: adverse physical events and storage in inappropriate conditions. The handwritten record of the message on paper is an indispensable source of information for historians and researchers of the past, therefore, measures were taken to try to diagnose the negative changes in the state of preservation and eliminate the visible threats, as well as to select those elements of the resource that require professional conservation work.

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.

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:
The problems of landscaping of Poland become in recenttimes significant. On a level with the protection of the natural environment they become the determinant of national culture, its environmental and aesthetic awareness. The article presents the role of the alley in shaping the identity of the Polish cultural landscape, including in the background of legal requirements. The road or a street apart from acting communication functions is also an element which orders the space. In many places of Poland, both the city tissue, this with historic values as well as former transport routes through various measures, including spatial transformations have been undergone and continue to undergo major reconstruction, which is often equivalent to the destruction of tree stand primarily. The remaining alleys in the contemporary perception of the urban landscape are the cultural heritage, mindlessly destroyed by more than 60 last years. Different activities superimpose here, both planning and cultural activities supported by most flawed, ineffective legislation, which provides no effective protection of alleys and the historic tree stand for today at roads, in the sacral and sepulchral setting-ups. Many historic alleys do not longer exist, although today's roads and streets were mostly carried out along the historic trails. The article focuses on the causes of this phenomenon. The article presents the history of legislation on the greens, which existed in Poland since the XVIII century, the rules on the order of planting and maintaining trees on public roads from 1922, from 1936, which had a significant impact on shaping the identity of the cultural landscape in Poland.

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:
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:
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.

The present study documents the ethnomedicinal and conservation status of 91 herbs belonging to 81 genera and 66 families in tehsil Banda Daud Shah during 2012-2013. The information about conservation and ethnobotanical was collected through questioners and personal interviews during fieldwork using the IUCN 2001, Red Data List Categories and Criteria. Among these 36 species were found to be rare, vulnerable (30 species), infrequent (13 species), endangered (8 species) and dominant (4 species). From the present investigation we concluded that most plant species are going to become endangered because the natural vegetation area was change into urbanization.

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’.
W Europie siedlisko 1110 ‘Piaszczyste ławice podmorskie’ jest objęte ochroną w 766 obszarach Natura 2000. 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’.
