The aims of the present study were: 1) to perform a detailed mapping of the distribution of conservationally significant (endemic, vulnerable, endangered and protected) plant species in the group "Kanarata and Quarry Drenaka" of the protected area "Pobiti Kamani" for 2020 yr in GIS environment; 2) based on the overlap of the distribution sites of plant species, to determine the "hot spots" of plant biodiversity, access to which should be limited in order to protect them and at the same time to identify areas with no or low concentration of conservationally important species in order to trace and mark the tourist paths in the protected area. In order to investigate the distribution of six plant communities, a detailed GIS mapping was performed. As a result of the study, detailed distribution maps of investigated species communities in Central Group were drawn. Special attention is paid to the zones where two or more communities were overlapped. The identification of the areas with concentration of conservation-significant species and localization of "hot spots" is crucial for protection management of the group "Kanarata and Quarry Drenaka" of the protected area "Pobiti Kamani". The model of "hot spots" and the model of overlapping are applicable and in combination with detailed distribution maps are fundamental for more successful protection and conservation. The suggested touristic zones with lack of conservation species can be used to trace and to construct environmentally friendly tourist trail and paths without destroying and harming the species, their habitats, and the aesthetic and recreational value of the landscapes.

The problem of invasion of Sosnowsky hogweed (Heracleum sosnowskyi Manden.) In the Lipovaya Gora SPNA in Perm is considered. A map of distribution of hogweed cenopopulations in the protected area is presented. The results of the influence of the invasion of Sosnovsky hogweed on the biodiversity of vascu-lar plants of some plant communities are presented. It was revealed that the invasion of hogweed into phytocenoses of the Lipovaya Gora protected area leads to a decrease in the biodiversity of vascular plants by about 26.4% (up to 12 plant species). The ways of introduction of cow parsnip into the communities of the protected area are considered. High seed productivity, high projective cover, reaching in some cases 100%, high phytomass, the presence of dormant seeds, rapid development in spring, and high anthropo-genic load on the territory determine the rapid spread of H. sosnowskyi.

Abstract Collecting information about crop wild relatives (CWRs) as vital genetic resources for food security is the first stage of monitoring them. In this study, which was conducted in a protected area, we surveyed the conservation status of CWR sand, and the interaction between the condition of these plants and their local use. From 338 plant species in the area, 179 crop wild relatives in 38 families were identified. None of them is threatened, but some endemic rare or vulnerable plants such as Alkanna frigida Boiss. could cause some anxiety. Among these species 19 species of CWRs have edible usage in this area. Harvesting the crop wild relatives from nature by the local people is seen as a conservative factor although this is not usually true of other species.

Abstract The paper presents the results of investigations on the aquatic vegetation, along the Romanian bank of the Danube River, in the area of Porţile de Fier (“Iron Gates”; Mehedinţi and Caraş-Severin counties), a Natura 2000 site. Twenty-three plant communities were identified from Lemnetea minoris and Potametea pectinati classes. The survey led to the identification of some newly described phytocoenotaxons in this protected area. All the plant communities in this paper are documented by phytosociologic tables, being accompanied by coenotaxonomic, phytogeographical, ecological and social strategies analysis, in order to assess their conservation status, as the main tool for management decisions.

This study was undertaken to determine vascular plant species composition, vegetation structure, and floristic quality of the major plant communities in the windblown sand deposits of northwestern Illinois during the growing seasons of 2002 through 2005. The major plant communities of the Ayers Sand Prairie Nature Preserve in Carroll County, Big River State Forest in Henderson County, Lost Mound Unit of the Upper Mississippi River Wildlife and Fish Refuge in Carroll and Jo Daviess counties, and the Thomson-Fulton Sand Prairie Nature Preserve located in Whiteside County were examined and the importance values determined for the plant species present. Located on broad terraces of the Mississippi River, these nature preserves and natural areas are remnants of a larger grassland/savanna/forest complex that contained extensive marsh; wet, mesic, and dry sand prairie; sand savanna; and sand forest communities. Most of the sand deposits are now cultivated and the original vegetation is found only in protected remnants, some of which are relatively large. The mature dry sand prairies were dominated by Schizachyrium scoparium; other important species were Opuntia macrorhiza, Dichanthelium villosissimum, Ambrosia psilostachya, and Tephrosia virginiana. Other assemblages of prairie and exotic species were encountered in successional sand prairie communities. Generally, the mature prairie communities in these preserves and natural areas had 35 or more species present in the study plots. Savanna and closed canopy forest communities were also examined. The dry sand savannas were dominated by Quercus velutina and Q. marilandica, dry sand forests were dominated by Q. velutina, and dry-mesic sand forests were dominated by Q. alba and Q. velutina.

The Philippines has approximately 1,100 species of lycophytes and ferns, and this represents approximately 9% of the worldwide fern flora. Botanical explorations and local documentations continue to expand the list. Local documentations increase our knowledge on species distribution and conservation status, which are essential in biodiversity conservation. This paper reports on a survey of the pteridophytes of Adams, Ilocos Norte, one of the remaining floristic sites in Luzon Island, Philippines. A series of floristic surveys conducted at selected sites in Adams recorded and vouchered 47 species, 34 genera and 21 families of pteridophytes. Among all these pteridophytes, six are threatened Philippine plant species. These are Platycerium coronarium, Ceratopteris thalictroides, Tectaria psomiocarpa, Psilotum nudum, Blechnum egregium, and Angiopteris evecta. This study contributes to the baseline data on Philippine pteridophytes especially on their distribution, and can serve as reference for biodiversity conservation and restoration efforts as ferns may help in the stabilization of degraded lands and facilitation in plant communities.

The vegetation of the protected area of Lake Pamvotis (Epirus, NW Greece) was studied and classified into habitat types according to the Council Directive 92/43/EEC. The main vegetation types encountered in the Ioannina Basin and the south-western part of Mt Mitsikeli are: (1) Quercus coccifera shrublands, (2) degraded deciduous oak forests, (3) Mediterranean arborescent mattorals with Juniperus, (4) Oro-Mediterranean heathlands, (5) willow low open forests, (6) οriental plane woods, (7) plant communities supported by calcareous substrates, (8) aquatic macrophyte assemblages, (9) reed beds and rush meadows. Twenty plant communities belonging to twelve alliances, eleven orders, and ten phytosociological classes were discerned. The Asplenio ceterach-Aurinietum saxatilae is described as a new association and the Eleocharito palustris-Alismatetum lanceolati is reported for the first time from Greece. Eleven habitat types were identified and their conservation status was assessed. Three habitat types (4090, 8210, 91M0) were in favourable conservation status, while one (5210) is in unfavourable-bad conservation status. The rest are in unfavourable-inadequate conservation status, with several pressures and threats recorded.

Four species of Consolea have been reported from the Cuban archipelago, each of which has been considered under threat of extinction. During the last three years various expeditions were carried out to try to update existing information about the conservation status of populations of the different species and their primary threats. Likewise, we revised and identified herbarium specimens from HAC, HAJB, HMC, MNHN, and NY to put together distribution maps for each species on Cuba. All native species of Consolea on Cuba are under threat of extinction/ extirpation. Consolea moniliformis is the species with the largest populations on Cuba, while C. macracantha displays the widest range of any other species on the island. Two new localities of C. macracantha were found during this study, but likewise, showed the only signs to date of attack by the invasive moth, Cactoblastic cactorum. Among the principle threats detected for species of Consolea on Cuba are exotic, invasive plant species, livestock grazing and development. We provide a key to the species on Cuba.

Quezon Protected Landscape (QPL) is a tropical rainforest situated at the southern Sierra Madre mountain range. However, it is subjected to anthropogenic pressure that poses threats to its flora and fauna. This study was conducted to describe the plant diversity, assess their ecological and conservation status, and to identify current anthropogenic threats in various vegetation types in QPL. Vegetation assessment was done using quadrat method established at different land use types wherein ninety 10×10 m nested plots were used for trees, 5×5 m subplots were used for herbs and shrubs, and 1×1 m subplots were used for grasses. The study documented a total of 328 species belonging to 84 families and 208 genera with 2,737 individuals. Species diversity is high as revealed by the values obtained from species diversity (H’) and species evenness (J’) indexes. Out of 172 tree species identified, the most important species are: Parashorea malaanonan (Blanco) Merr. in the regenerating and lowland evergreen dipterocarp forest; Diospyros pyrrhocarpa Miq. in the karst forest; Leucaena leucocephala (Lam.) de Wit in the secondary forest; and Cocos nucifera L. in the agroforest. Assessment of ecological status showed that out of 328 species, 213 (64.94%) are native, wherein 65 (19.8%) are endemic, and 115 (35.06%) are introduced. Forty-five species (13.72%) are threatened in which 25 of those are endemic in the Philippines. Overall, QPL has a wide array of plant species and threats such as the illegal extraction of natural resources, encroachment, cleanliness and presence of invasive alien species. So, it is recommended that protection and awareness campaign should be done for conservation and sustainability.

Conservation Assessments

The IUCN Sampled Red List Index (SRLI) is a policy response by biodiversity scientists to the need to estimate trends in extinction risk of the world's diminishing biological diversity. Assessments of plant species for the SRLI project rely predominantly on herbarium specimen data from natural history collections, in the overwhelming absence of accurate population data or detailed distribution maps for the vast majority of plant species. This creates difficulties in re-assessing these species so as to measure genuine changes in conservation status, which must be observed under the same Red List criteria in order to be distinguished from an increase in the knowledge available for that species, and thus re-calculate the SRLI. However, the same specimen data identify precise localities where threatened species have previously been collected and can be used to model species ranges and to target fieldwork in order to test specimen-based range estimates and collect population data for SRLI plant species. Here, we outline a strategy for prioritizing fieldwork efforts in order to apply a wider range of IUCN Red List criteria to assessments of plant species, or any taxa with detailed locality or natural history specimen data, to produce a more robust estimation of the SRLI.
