“…Для флори епіфітних і епіксильних мохоподібних Снопківського парку характерні такі ж процеси, як і для урбоекосистеми Львова загалом. Насамперед це спрощення структури флори та втрата її специфічності [4,5,[13][14][15][16].…”

“…Інтенсивність міського «теплового острова» трохи згладжується у парках і лісопарках. Таким чином, паркам і лісопаркам в умовах урбоекосистем властиве значне різноманіття бріофітів, які зайняли свою нішу і не лише стали певним доповненням до фототрофного блоку, але і слугують розширенню біорізноманіття, створюючи умови для заселення іншою біотою [15,16].…”

The species diversity and substratum preferencies of Bryophytes in the territory of the local park-monument park “Snopkivsky” in the urban ecosystem of Lviv are given in the article. The bryoflora of the Snopkivsky Park includes 61 species of bryophytes from the divisions Marchantiophyta and Bryophyta. The high position of the families Brachytheciaceae, Orthotricaceae, Pottiaceae, Bryaceae in the floristic spectrum reflects the specificity of the park’s local conditions. The percentage of these families in the floristic spectrum is 45.9 % of the total species richness. This distribution is characteristic of aridic natural zones, which indicates the dry condition of the urban microclimate. At the same time, a good representation of the boreal and nemoral forest families such as Mniaceae, Amblystegiaceae, Hypnaceae (21.3 % of the total species richness) reflects the natural features of the territory (the zone of broad-leaved forests), which spontaneously reproduced on part of the Park territory or were created artificially in ornamental gardening. In this part of the Park with spontaneous silvatisation the largest number of bryophyte species is concentrated and the moss cover is the most abundant. Poor representation of Marchantiophytes indicates a significant degree of anthropization of the studied urban ecosystem. There is an increase in the number of anthropogenic ecotopes in the Park, which is reflected in a significant upgrowth in the fraction of epilithic bryophyte species. Ravines and abandoned quarries have the greatest conservation value for mosses on the Park territory. Some anthropophobic species as components of epigeic, epiphytic and epixylic substrates groups, which are not characteristic of intensively urbanized areas, are occur here. No rare bryophyte species were found within the park. However, floating liverwort Riccia fluitans, which is not typical for urban areas in general, was found in the Zelene Oko lake. Calcareous tufa deposited in the bed of hard-water streams at the headwaters of the Snopkivsky stream is a specific habitat for bryophytes. Indicators for hard-water springs with tufa formation of European lowland arias bryophytes species (Apopellia endiviifolia, Cratoneuron filicinum and Platyhypnidium riparoides) were found here. Amphibious (primarily calciphilic tufa-forming) and free-floating bryophyte species are equally not typical for urbanized ecosystems and occur here only sporadically: this fact underlines the conservation value of the researched park for the preservation of bryophytes microhabitats within the city boundaries. The conservation of silvatic areas, both spontaneous and artificial, is an important condition for the effective functioning of the park as a semi-natural ecosystem. The diversity of bryophytes, their species composition and cover abundance are indicative of the integrity of urban ecosystems on the territory of the park “Snopkivsky”.

“…Зазначимо, що для горбогірної області Розточчя, що межує з територією досліджень, ці види не відзначались раніше . Також вони не відомі для суміжних із досліджуваною лісопаркових зон, таких як "Погулянка" та "Знесіння" (Mamchur et al, 2021). Отже, можна зафіксувати першу знахідку D. tophaceus та G. aeruginosum в околицях Львова.…”

Petrifying Springs of Eastern Vicinity of Lviv City as Valued Objects of Living and Inanimate Nature

An assessment of the condition of the petrifying springs in the eastern vicinity of Lviv City as objects of living and non-living nature and their nature conservation value was carried out. The investigated travertine springs are confined to the sources of small rivers associated with water-erosive landscape complexes. Travertine deposits in the studied areas are mostly related to groundwater outputs in the sides of deep, branched V- or U-shaped, usually wooded ravines, which have the local name "debra". Springs are wedging out in sites of contact between Neogene limestones and waterproof Сretaceous marls and often produce powerful deposits of travertines (calcareous tufa). These sources are forming the headwaters of small rivers in the region. Considering the long period of management of the region and the high rate of urbanization, at the modern stage, the complex of natural factors is often joined by anthropogenic influence, which in one way or another affects the natural processes of tufa accumulation. As our research has shown, all the surveyed streams have been anthropogenically altered in one way or another. Obviously, the main reason for this is the location of the streams in the forest park zone of Lviv with intensive visits by vacationers and the close proximity to human habitation. Only 15 springs (27.8%) retain their natural character and the rest are significantly transformed. Among the last 20 sources (37.0%) suffer minor changes due to the expansion of sources and straightening or deepening of their channels; such ones can be defined as semi-natural. Today, more than a third of springs (19 / 35.2%) are intensively managed and have completely lost their natural features, mainly due to capping and the construction of reservoirs. Despite the significant transformation, many of such sources can have health (bathing), economic (alternative sources of water supply), sacred ("holy water"), historical (named after famous personalities), aesthetic (originally designed) and scientific and educational (limestone exposure and travertine) values. The most interesting and outstanding of them need to be given the conservation status of the Nature Reserve Fund. Key words: petrifying springs; travertine (calcareous tufa); rare habitats; natural monuments.

Factors of influence on the development of organic land use under the conditions of marital law

The importance of increasing the pace of production of organic products has been proven, since traditional technologies used in the production of agricultural products significantly disrupt the natural balance and cause significant environmental problems (disruption in ecosystem chains, environmental pollution, man-made pollution caused by military actions, deterioration of people's health). It was found that a number of highly developed countries that cooperate with Ukraine on various projects and programs are involved in this process. An in-depth study of the field of organic land use in Ukraine under the conditions of military operations made it possible to identify existing problems and assess their impact on the development of this segment of activity. A number of restraining factors affecting the development of organic land use have been identified, one of the determining factors being the creation of an appropriate institutional environment. The need for the development of land management projects regarding the organization of organic land use territory is substantiated. Incentives are presented as motivating factors for both consumers and producers of organic products (incentive payments to economic entities, introduction of free pricing for manufactured products, introduction of preferential taxation and preferential loans, obtaining the possibility of conducting certification in a remote format, etc.) despite the military situation in the country Potential factors for development and development of organic land use are also proposed. The given triad of factors can be implemented logically and sequentially and to a large extent simultaneously.
