Results of non-native flora surveys on Samara Dniprovska River valley within the designed National Park «Samarsky Bir» were analyzed in the paper. Scientific justification on first stage creation of the national-level National Park «Samarsky Bir» was prepared in 2012. Its area included the main park area with floodplain, arena and gully landscapes of the rivers Samara and Oril interstream. List of vascular plant species on floodplain, arena and gully habitats of Prisamar'ya counted 887 species. They are classified as 5 divisions, 6 classes, 108 families, 429 genera. This article presents a list of non-native flora fraction with bioecological characteristic of the plant species. The surveys were conducted by conventional methods on vascular flora studying. Analysis of the main plant ecomorphs was carried out by A. L. Belgard ecomorph system (1950). Invasion of plant species in the steppe zone of Ukraine has a long history complicated by significant anthropogenic transformation of the territory. We investigated the status of non-native plants, their ecomorphs, and tendency to invasiveness on the territory of National Park «Samarsky Bir» designed. Presence of 195 adventitious vascular plant species belonging to 48 families was determined. Of them, 7 families with the greatest abundance of non-native species contained 113 taxa (58 % of the total); 20 families were represented with 2–7 advents, and 20 families contained only 1 non-native species. Thus, today the share of non-native species in the vascular flora of the region accounted for nearly 22 %. Most of adventitious species are mesoxerophytes and xeromesophytes. In a cenomorphic relationship, vegetation being ruderal on the territory of Ukraine is dominated in composition of non-native flora. Within the total number of adventitious species, archaeophytes amount up 44 %, whereas neophytes come up to 56 %. The greatest abundance of adventitious species has been found in Brassicaceae, Asterasea and Poaceae families (15 %, 12 %, and 11 % of the total, respectively). 119 non-native vascular plant species were found in the steppe cenoses, 79 species in the gully and watershed forests, 90 species in floodplain forests, and 52 species on the territory of the sandy terrace. Among all the non-native species, 28 species have been identified as invasive, and there was a trend to increased invasiveness of some species in recent years. Among heterogenous species 12 of them were identified as invasive, and there was a tendency to increase theinvasiveness of some species in recent years. The analysis provided on non-native flora in the National Park evidences significant anthropogenic transformation of the territory; that requires establishment of appropriate regime on protection of this important ecological object.

The paper presents a systematic list of vascular plant species recorded at 78 cemeteries in the Roztocze region and surrounding areas. 543 species belonging to 75 families were recorded. Of these, 99 foreign and 43 native species were cultivated. 41 species introduced by humans to cemeteries can be regarded as the so-called established cemetery species. These species, once planted on graves, continue to grow or even spread after people stopped cultivating them.

AbstractThe paper presents analysis of the results of floristic studies carried out over 25 years in the Viešvilė State Strict Nature Reserve (VSSNR) and its buffer zone. The list of 703 vascular plant species including the data on their distribution and dynamics of abundance are provided. The native flora of the VSSNR includes 580 species, i.e. amounts to 47% of all native vascular plant species recorded in Lithuania. Since 1991, after the establishment of the Reserve, 15 species have become extinct and 30 have become endangered as a result of natural succession. Among 37 alien species recorded in the Reserve, four species are penetrating into natural habitats and threatening their existence. It was ascertained that about half of all species were recorded in meadows and glades of the forests, i.e. in the habitats, which occupy less than 1% of the whole territory. These are also habitats of most extinct and endangered species. Riparian and fontinal black alder woods are the most rich in vascular plant species among forest habitats.

The vascular flora identified in 1968–1969 in three rice fields of the Winyah Bay Estuary at the Bell W. Baruch Institute for Marine Biology and Coastal Research, Georgetown County, South Carolina, abandoned in 1915, was compared with the vascular flora present in 1987–1991 and 2013–2015. Twenty vascular plant species were identified in 1968–1969 and 22 in 2013–2015 at the most saline marsh, Thousand Acre Rice Field. Forty-seven taxa were reported at Airport Marsh in 1968–1969 and 27 in 2013–2015. Fifty-six taxa were reported at Alderly in 1968–1969 with 41 identified there in 2013–2015. A parsimony algorithm was used to evaluate the distribution and co-occurrence of vascular brackish marsh species in these fields sampled at the three intervals. There was a reduction in flora at the two least saline sites, Alderly and Airport Marsh, from 1968–69 to 1987–91 and 2013–2015. Three factors—rising sea level, an increase in water salinity, and invasion by Phragmites australis—may explain this shift. There was also a shift in the flora at Thousand Acre Rice Field from 1967–1969 to 1987–1991 and 2013–2015 after the marsh was savaged by Hurricane Hugo in 1989. Invasion by non-native Phragmites australis at all sites and increase in water salinity at all sites best explain the reduction in vascular plant species at Airport Marsh and Alderly over the 47-year collection period.

The flora of two towns and two settlements in the northern taiga and forest-tundra of Northwest Siberia (Russia) are considered. Urban species lists are limited (61–119 vascular plant species) and mainly consist of native species with a predominance of perennial herbs. Various urban functional zones (industrial, residential, recreational, vegetable patches) differ by species composition, and this difference increases in the course of city development. In the industrial zone, vegetation composition is closer to the native flora, because of the low number of adventive species. Maximal diversity is due to decorative plants, cultivars and southern weed distribution, and is typical to residential neighborhoods. Species diversity increases mainly because of woody plants introduction. Alien species are represented generally by a small number of individuals. The severe climate and poor soils limit their abilities to spread in the Far North. Urbanization forces the reduction of aboriginal biodiversity, but in northern areas where native species have the adaptive advantage, this effect is minimal. Changes in flora since 1995 were analyzed in the town of Novy Urengoy (Yamalo-Nenets Autonomous Okrug, Russia). Plant diversity increased by about 20 % in all functional zones, although some alien and natural species were not recorded in 2018.

Bach Ma National Park (BMNP) is recognized as an essential biodiversity hotspot in Vietnam because of its diverse topography, high species richness and threatened and endemic species. This study updates the richness and distribution of vascular plant species in the BMNP by intergrading data from literature, field surveys, key-informant interviews and participatory observations. Our results showed that the park has a high diversity of vascular plants with 1,874 species belonging to 192 families, 6 phylums including Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta, Pinophyta, and Magnoliophyta. It also indicates that 199 out of 1,874 vascular species in the BMNP are listed as endangered, precious and rare plant species of Vietnam. In particular, 55 species are part of the IUCN 2020 list, in which 9 are critically endangered species (CR), 15 are endangered species (EN), and 31 are vulnerable species (VU). According to the rankings of the Red List Vietnam (2007), 6 species of CR (accounting for 13.64% compared with the whole country), 36 species of EN (20%), and 52 species of VU (26%) were found in this area. The results provided that vascular plant species are distributed into 2 types based on high altitude (threshold at 900m), but there are no dominant communities. The findings may be essential information for foresters and biologists to recognize and use it as the newest update for their next scientific research in conservation and resource management. Vườn Quốc gia (VQG) Bạch Mã được xem là một điểm nóng đa dạng sinh học quan trọng ở Việt Nam vì địa hình đa dạng, độ phong phú loài cao, đặc biệt là các loài đặc hữu và nguy cấp. Trong nghiên cứu này, chúng tôi đã cập nhật sự phong phú và phân bố của các loài thực vật bậc cao tại VQG Bạch Mã bằng cách kết hợp dữ liệu từ tổng quan tài liệu, khảo sát thực địa, phỏng vấn người am hiểu và điều tra có sự tham gia. Kết quả cho thấy VQG có hệ thực vật bậc cao phong phú với 1.874 loài, thuộc 192 họ, 6 ngành bao gồm Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta, Pinophyta, Magnoliophyta. Kết quả chỉ ra rằng 199 trong số 1.874 loài thực vật bậc cao tại VQG này được xếp vào danh sách các loài nguy cấp của Việt Nam. Đặc biệt, có 55 loài thuộc danh mục của IUCN năm 2020, trong đó có 9 loài Cực kỳ nguy cấp (CR), 15 loài Nguy cấp (EN) và 31 loài Sẽ nguy cấp (VU). Trong khi đó, theo xếp hạng của Sách Đỏ Việt Nam (2007), nghiên cứu cho thấy có 6 loài CR (chiếm 13,64% so với cả nước), 36 loài EN (20%) và 52 loài VU (26%). Phát hiện của chúng tôi cũng chỉ ra rằng đặc điểm phân bố của các loài thực vật bậc cao ở VQG Bạch Mã gồm 2 kiểu rừng dựa trên độ cao (mức 900m), nhưng không có quần xã nào chiếm ưu thế. Các kết quả này được kỳ vọng sẽ là nguồn thông tin cần thiết cho các nhà hoạt động lâm nghiệp và sinh vật học sử dụng nó như một bản cập nhật mới nhất cho các nghiên cứu khoa học tiếp theo trong bảo tồn và quản lý tài nguyên.

The highlands and mountains of Iceland are one of the largest remaining wilderness areas in Europe. This study aimed to provide comprehensive and up-to-date data on non-native plant species in these areas and to answer the following questions: (1) How many non-native vascular plant species inhabit highland and mountainous environments in Iceland? (2) Do temporal trends in the immigration of alien species to Iceland differ between highland and lowland areas? (3) Does the incidence of alien species in the disturbed and undisturbed areas within Icelandic highlands differ? (4) Does the spread of non-native species in Iceland proceed from lowlands to highlands? and (5) Can we detect hot-spots in the distribution of non-native taxa within the highlands? Overall, 16 non-native vascular plant species were detected, including 11 casuals and 5 naturalized taxa (1 invasive). Results showed that temporal trends in alien species immigration to highland and lowland areas are similar, but it is clear that the process of colonization of highland areas is still in its initial phase. Non-native plants tended to occur close to man-made infrastructure and buildings including huts, shelters, roads etc. Analysis of spatio-temporal patterns showed that the spread within highland areas is a second step in non-native plant colonization in Iceland. Several statically significant hot spots of alien plant occurrences were identified using the Getis-Ord Gi* statistic and these were linked to human disturbance. This research suggests that human-mediated dispersal is the main driving force increasing the risk of invasion in Iceland’s highlands and mountain areas.
