 The floristic study and the conservation value analysis of forest from the Jordan river middle basin are addressed in this research. This vegetation forms part of the subtropical mountain forests or Yungas, one of the most diverse ecosystems on Earth. Present forest species were surveyed, and the vegetation Interest Conservation index (INCON) was determined based on a series of conservation value criteria (Phytocenotic, Territorial, Mesological, Ethnobotanical, Perceptual and Didactics) recorded in the field. Available data on socio-cultural aspects of the area was also included in the study. All plants were identified up to genera and/or species. INCON was calculated from the sum of scoring assigned to each analyzed criterion. As a result, 42 forest species were identified; for each one, its conservation status was performed, including the altitudinal vegetation belt, biogeographical origin (at least for the genus), and their ethnobotanical value. The INCON obtained (135 points) showed the high natural, ethnocultural, landscape, and educational value of these forest vegetation according to the criteria analyzed. This information provides a useful tool to have a more precise knowledge of the diversity conservation status of Las Yungas. It also serves to recognize the biological and environmental relevance of this area, whose usefulness can be used for conservation purposes or decision making on protection plans.

The existing nature conservation objects that are part of the Dnistrovskyi Regional Landscape Park are characterized and mapped. There are more than sixty different types of WFD objects in and around the park. All objects are tabulated. Also, geological, geomorphological, hydrological objects have been identified that have scientific, recreational and educational value, which gives grounds for granting them conservation status. This is a large number of rocks of different ages (Silurian, Devonian, Jurassic, Cretaceous), which makes it possible to study the history and condition sof the territory. The location is mapped. Also on the map as places of interest are the places of manifestation of modern geomorphological processes. Fluvial, karst, gravity, erosion and other processes are most evidentin the park. The dynamics of karst processes haveled to the formation of numerous caves and cave formations, which are valuable from the scientific and recreational plan. A mong the hydrological and hydro-geological features are waterfalls, marshe sand ground water exits to the surface in the form of springs. Historical and cultural sites occurring with in and around the park are characterized and mapped. The seare objects of Paleolithic heritage (the oldestin Bukivna, Horodnytsia), Kievan Rus' period, ruins of ancient castles (Rakovetsky and Chekrnelitsky) and fotresses, lordlye states, ancient churches, of which there are more than thirty, existing and in active in the region. The most ancient are the village of Michalce), monuments of liberation competitions (hiding places) and places of great historical battles. It maps and describes the existing route sand objects of the tourist infrastructure of the Dnistrovskyi RLP. The park and surrounding areas haves ignificant natural and recreational potential. The presence of a large number of diverse natural sites make sit possible to create attractions for tourism development in the region. The presence of historical and cultural heritage en hances the use of the territory. New routes and proposals for improvement of the tourist infrastructure of the territory were developed: creation of an eco-educational visit center, placement of agroosel complexes, arrangement of places for stops during the Dniester alloys, creation of a network of tourist points at the places of passage of route sand places of rest of residents, development and in stallation of new information standsne are xisting tourist natural and historical sites in the study area. Key words: Dnistrovskyi RLR, Nature Reserve objects, historical and cultural sites, nature monuments, recreational resources, tourism.

Located in the Iron Gates Natural Park, Romania, at the foot of the Locvei Mountains, the Sfanta Elena Karst Plateau is a very picturesque territory, characterized by a karst relief, covered by High Nature Value grasslands. In the last decade this territory has been subjected to increasing anthropogenic pressures, and specific concerns on biodiversity have been raised after the construction of a wind farm in 2011. Starting from a concern expressed by a scientist, our study aims to provide current data on plant species with conservation value and to assess the conservation status of orchid-rich grasslands around wind turbines after ten years of wind farm operation. During the operation period we identified 19 plant taxa with conservation value, eight of which which are orchid species. Four of them are new reports for this territory: Gymnadenia conopsea, Neotinea ustulata, Neottia nidus-avis and Orchis simia, as well other rare taxa such as Cirsium grecescui, Lathyrus sphaericus, Linum hologynum and Rumex thyrsiflorus, are mentioned for the first time. The orchid-rich grasslands in the wind farm area correspond to the Natura 2000 habitat 6210* whose structure and floristic composition are within the acceptable limits of Favourable conservation status. The conservation status of plant species is directly dependent on the quality of their habitat, as well as the variety of pressure and threat factors in the area.

Cibodas Botanic Gardens (CBG) shall keep performing botanical exploration and ex situ conservation as part of the effort to rescue tropical montane rainforest plants, which tend to decrease in their natural habitat. Pasir Banteng and Pasir Pogor, Mount Gede Pangrango, were selected due to the potential threat and limited information on plants collected from these sites. The objectives of this study were to collect valuable plants, which have a conservation value and explore their potential usefulness. The study has begun by establishing a list of collectible plants. Then, the field activities were conducted by a plant collection explorative method along the hiking route, from 750 to 1,500 m asl, low-mid mountain as height as CBG, with no specific sampling point (found and collected). These plants have field treatment, were delivered to CBG, and would later be maintained in the garden. The study has obtained 31 species collected from Pasir Banteng and 20 species from Pasir Pogor. There were 35 families, with Orchidaceae being the most collectible. Some crucial findings were nine species included as least concern (LC) and a species as endangered (EN), based on their conservation status. At least six new species were identified as the garden enrichment of the CBG. In addition, at least fifteen species have potential utilization as construction materials, 29 species as ornamental plants, twelve species as medicinal plants, and some plants possessing multi-utilization. The results were significant in adding the collection’s richness and enhancing the conservation value of the plants conserved by CBG. It was also contributed to describing the plant species information of these sites. Keywords: botanical exploration, ex-situ, Pasir Banteng, Pasir Pogor, plant conservation

<em>Carex disperma</em> Dewey reaches its south-eastern range limit in north-eastern Poland. It has often been confused with <em>Carex loliacea</em> L. In this paper the diagnostic features of both species are presented. A total of about 47 reliable localities of <em>C. disperma</em> 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 <em>C. disperma</em> based on herbarium records, credible literature data and the author's own data is provided, as well as maps of distribution of both <em>C. disperma</em> and <em>C. loliacea</em> in Poland. The existence of <em>C. disperma</em> × <em>C. loliacea</em> hybrid was not confirmed. Considering the number of localities, dynamics and population sizes of both species it is clear that <em>C. disperma</em> is a species with higher conservation value than <em>C. loliacea</em>. Unlike <em>C. disperma</em>, the latter species is not threatened with extinction in Poland. The resources of <em>C. disperma</em> are very limited and the species needs conservation measures such as creating sufficiently large nature reserves where appropriate hydrological conditions can be maintained.

Sandbar Lake Provincial Park (Sandbar Lake) covers 8053 ha in the boreal forest in northwestern Ontario. Within the park boundary are natural forests representative of those in the region, as well as forests that are heavily disturbed from resource extraction activities, which are prevalent in northwestern Ontario. The lichen biota in this part of the boreal forest is known to be rich and abundant, but lichen diversity is also known to be negatively impacted by disturbances (e.g., timber harvesting, mining, and climate change). Therefore, lichens can be used to monitor the effects of these disturbances, but baseline data are required. Here, we present the results of the first detailed inventory of the lichens and allied fungi of Sandbar Lake. We report 139 species in 69 genera from 16 sites that represent all macrohabitats present in the park. Seven species have a provincial conservation status rank from S1 to S3 (critically imperilled to vulnerable), and one species, Arthrosporum populorum, has previously been collected only once in northwestern Ontario. Our results fill biogeographic gaps for many species and allow lichens to be used as biomonitors during further study at Sandbar Lake. We show that Sandbar Lake has important conservation value, and our data provide an opportunity for further study in an area with no previous research on lichens.

The Poledňana Nature Reserve is located in the northeastern part of the Beskydy PLA, close to Staré Hamry town. The subject of protection are old growth forests with natural-like tree composition. During the survey in 2021, 43 species (42 terrestrial and one aquatic) of gastropods were recorded. The species composition consists predominantly of woodland dwellers (28 spp.; 65%) followed by eurytopic (5; 12%), hygrophilous woodland dwellers (4; 12%), hygrophilous (3; 7%), strongly hygrophilous (1; 2%) and one (2%) aquatic species. Endangered Bulgarica cana, indicating high conservation value of local forest fragment, vulnerable Daudebardia brevipes, Eucobresia nivalis, Vitrea transsylvanica, nearly threatened Bielzia coerulans, Bythinella austriaca and Vestia turgida are species of conservation importance. There is need to preserve non-interventional regime in the most valuable parts to retain and to establish favorable habitat conservation status. The tree composition in spruce-dominated areas should be gradually changed towards natural composition.

Geopark is a sustainable regional development concept that combines geological, biological, and cultural diversity through conservation and education activities to improve the community's welfare. Kebumen Regency has a National Geopark Karangsambung-Karangbolong (GNKK) covering 543,599 Km2 with 41 geosites, ten cultures, and eight biosite since 2018. The northern part of the area is a geological heritage that is widely used for field geological education. The study aims to identify and assess geosites and geomorphosite in the north area, describing the region's geomorphological processes and geological evolution. Field research was conducted to get an overview of geological diversity, geomorphology, and geosite and determine the selected geomorphosite. Geomorphosite assessment is done quantitatively using the Kubalikova method by assessing five main parameters that include; Intrinsic and scientific value, the value of education, economic value, conservation value, and added value. The scientific and intrinsic value of Pentulu Indah (PI) = 4, while Wagirsambeng = 3. Educational value of PI = 4, while Wagirsambeng = 2. Economic value is still not satisfactory, but P.I. = 2, while Wagirsambeng = 1.5. Conservation value of P.I. = 3.5, while Wagirsambeng = 2.5. Added value PI = 2.75 while Wagirsambeng = 1.5. Based on those, geomorphosite Pentulu Indah is 16,26 point or a good value (87.83 %) while Wagirsambeng is 10.5 point or fairly level (56.75 %).
