Abstract (sommario):

Wetlands have an important ecological function and economic value. However, with economic development and urban expansion, wetland plants have suffered serious damage. Rare and endangered plants are “thermometers” that reflect the health processes of their ecosystems. To better protect the wetlands in Sanya, China, we systematically investigated and analyzed the species, quantities, distributions, and community characteristics of the rare and endangered plants in the Sanya River basin using the sample and sample strip methods. We established a total of 152 quadrats, of which 46 contained rare and endangered plants. We identified 27 rare and endangered plants that mainly appeared in the tree and shrub layers. The dominant families and genera of the community were evident. However, the proportion of families and genera with fewer or single species was high, indicating that the species composition of the community is complex, and the plant species diversity is rich. The dominant species in each layer of the community were evident, and the rare and endangered plants are occasional species of the community. The community similarity in the urban areas was high, indicating that the rare and endangered plants in these areas require highly homogenous habitats. The community similarity in the suburbs was low, indicating that the rare and endangered plants in these areas are highly adaptable to different habitats. Threat factors and vegetation coverage degree had a significant impact on the number of species and population size of rare and endangered plants. Finally, according to our study and IUCN classification criteria for the endangered levels, Sonneratia × gulngai meets the CR (Critical Endangered) assessment criteria, thus we recommend upgrading it to the endangered level from VU (Vulnerable).

Abstract (sommario):

Indravati National Park, located in the Bijapur district of Chhattisgarh, India, is a biodiversity hotspot and a sanctuary for numerous plant species, including several recognized as endangered and possessing medicinal properties. This study aimed to document and provided valuable information on the endangered medicinal plants found within the Park. The research involved field surveys, interviews with local communities, and a comprehensive review of existing literature to compile data on these plants. The national park region is densely covered with green vegetation consisting of several important medicinal plants and some threatened and endangered plants of ethnomedicinal value. A total of 21 medicinal plants belonging to 16 families were reported during the study, categorized under rare, threatened and endangered categories with efficient ethno-medicinal applications. The maximum reported medicinal plant families were Bignoniaceae and Fabaceae (3 species report), Buseraceae (2 species report) followed by Apocynaceae, Araceae, Boranginaceae, Capparaceae, Lamiaceae, Lauraceae, Longaniaceae, Meliaceae, Piperaceae, Putranjivaceae, Rutaceae, Sterculaceae, Zingiberaceae with one species reported. The plants' parts used for the preparation of herbal medication included leaves, roots, bark, flowers, fruits, seeds, corms, whole plant, gum and resin derived from the plants, which were further used for the preparation of fresh extracts, juice, decoction, infusion, grounded paste, and dried powder. The documentation presented in this study not only contributes to the preservation of traditional knowledge but also serves as a valuable resource for researchers, policymakers, and conservationists working towards the protection of endangered medicinal plants in Indravati National Park, ensuring their availability for future generations and the advancement of herbal medicine and biodiversity conservation.

Abstract (sommario):

Chitral has diverse importance and has designated as a biodiversity hotspot of the country due to junction of Hindu Kush, Himalayan and Karakorum ranges, thus supporting maximum number of endemic plants. The conservation status of those endemic plants was assessed for three years, which have at least few points’ data as per IUCN Red List Categories and Criteria 2011, 2017and relied more on B criterion using “GeoCat” for AOO and EOO assessment. Some of the taxa were also compared with their previous status assessed ten years ago. This guideline will assist in country’s policies for conservation, threat assessment and sustainable management. Assessing a total of fifteen endemic taxa (species and subspecies), most are endemic to Chitral except Anaphalis chitralensis and Impatiens lemannii (both country’s endemic).Twelve species fall in the criteria for Endangered (EN) where as two species fall under Vulnerable (VU) and one falls in critically endangered (CE) threat category. The most CE (critically endangered) species is Astragalus commixtus with only 56 mature individuals while Astragalus erionotus, Delphinium kohatense were found to as VU (Vulnerable), rest all species like Polygonum cognatum, Plocama asperuliformus etc. are EN (Endangered). These species need immediate strategies for in-situ and ex-situ conservation for survival.

RARE PLANT LITERACY FOR BIOLOGICAL EDUCATION STUDENTS AS A RESULT OF THE TASK OF MINI RESEARCH AbstractIndonesia is known as one of the mega biodiversity countries, but ironically biodiversity in Indonesia has actually decreased, so that there are around 240 species of plants already included in the list of endangered plants. Therefore a movement is needed to educate the academic community, in this case Biology Education students through lecture assignments about endangered plant literacy. Thus the problem in this study is how the literacy of endangered plants of Biology Education students as a result of mini research in plant biology lectures. This research is a descriptive research. The research instruments included a mini research assessment sheet, which included aspects of the accuracy of determining plant species which included endangered categories, descriptions of morphology, classification and benefits of these plants. Biology Education students are assigned to survey, inventory and observe endangered plants in West Java. Overall endangered plant literacy of Biology Education students is good, but the aspect that is still lacking is in determining plant species in endangered categories. One of the plants found in Sukabumi area is Cynometra cauliflora including vulnerable plants. Need to develop assignments and assessments to assess endangered plant literacy of students to be more comprehensive. AbstrakIndonesia dikenal sebagai salah satu negara mega biodiversitas tetapi ironisnya keanekaragaman hayati di Indonesia justeru mengalami penurunan, sehingga ada sekitar 240 jenis tumbuhan sudah masuk dalam daftar tumbuhan langka. Oleh karena itu perlu dilakukan suatu gerakan untuk mengedukasi masyarakat akademis, dalam hal ini mahasiswa Pendidikan Biologi melalui tugas perkuliahan tentang literasi tumbuhan langka. Dengan demikian masalah yang diangkat pada penelitian ini adalah bagaimana literasi tumbuhan langka mahasiswa Pendidikan Biologi sebagai hasil tugas mini riset perkuliahan biologi tumbuhan. Penelitian ini merupakan penelitian deskriptif. Instrumen penelitian meliputi lembar penilaian mini riset, yang meliputi aspek ketepatan penentuan spesies tumbuhan yang termasuk kategori langka, deskripsi morfologi, klasifikasi dan manfaat tumbuhan tersebut. Mahasiswa Pendidikan Biologi ditugaskan untuk mensurvey, menginventarisasi dan mengobservasi tumbuhan langka yang berada di daerah Jawa Barat. Secara keseluruhan literasi tumbuhan langka mahasiswa Pendidikan Biologi termasuk baik, tetapi aspek yang masih kurang sekali adalah pada penentuan spesies tumbuhan dalam kategori langka. Salah satu tumbuhan yang ditemukan di daerah Sukabumi adalah Cynometra cauliflora termasuk tumbuhan berstatus rawan. Perlu pengembangan penugasan dan asesmennya untuk menilai literasi tumbuhan langka mahasiswa agar lebih komprehensif.

Abstract (sommario):

India houses about more than a thousand known medicinal plant species. Traditional Indian medicine, also known as Ayurveda, relies heavily on the use of medicinal plants for treating various ailments. They play a major role in our daily lives. The Western Ghats region in India is known for its rich biodiversity resources including a wide variety of medicinal plants. Western Ghats is among the world’s hottest 10 biodiversity hotspots and recently has been added to the world heritage list by the United Nations Educational, Scientific and Cultural Organization (UNESCO). But as these days most of the important medicinal plants present in Western Ghats are facing serious extinction issues and categorized as endangered plants by IUCN due to overexploitation, deforestation and similar anthropogenic activities. At the same time these IUCN reports on threat status highlights the importance of conserving these assets of nature for the betterment of future generations. This article comprehensively reviews the details about some important medicinal plants and their medicinal uses present in Western Ghats which are classified under endangered category.

Abstract (sommario):

The aim of this study is to present the updated list of rare and threatened vascular plant species in the Lublin province. The threatened species categories are presented according to the IUCN criteria. The regional list contains 408 species (that makes up 25% of the Lublin Region flora); 56 of which are considered critically endangered, 81 represent endangered species, 51 belong to the category of vulnerable species, and 49 are near threatened species, respectively. The presence of 37 species has not been confirmed and therefore they are listed as regionally extinct (RE). Of the total number of species, 134 are rare, but because the data about those species is insufficient, they have been classified as DD category (data deficient). The species of the genera: Alchemilla, Callitriche, Hieracium, Oenothera, Rosa, Rubus and Taraxacum have not been evaluated (NE category). Other species – those whose occurrence is doubtful and all neophytes were defined as not applicable (NA). The endangered taxa occur mostly in dry grasslands, deciduous forests, wetlands, and calcareous weed communities of cereal crops.

Abstract (sommario):

The Stephen F. Austin State University Arboretum occupies ten acres of campus property on the banks of LaNana creek, the stream that bisects the campus and the city of Nacogdoches, the oldest town in Texas. The mission statement of the Arboretum is to promote the conservation, selection and use of the native plants of east Texas. There are 19 species in east Texas that are either federally endangered, state endangered, or in danger of extirpation from the state. Many others face a serious decline in numbers as appropriate habitats diminish. A long-term project of ex situ and in situ conservation was initiated in 1992. Goals include: 1) acquire global position and vegetative analyses of endangered plant communities, 2) utilize ArcCAD® (a PC-GIS software) to archive a collection of maps, photographs, plant community data, and text, 3) maintain an ex situ collection of endangered plants from known provenances in the arboretum, and 4) reintroduction of species into appropriate protected habitats. The project involves the cooperation of several state and federal agencies and integrates the resources of a university horticulture program with the needs of endangered plant conservation.

Abstract (sommario):

The authors present a list of extinct, dying out and threatened species of vascular plants of the Sudeten Mts. (south-western Poland), based on their own field studies carried out since 1972, historical literature data, and herbarial collections. The list comprises 584 taxa, i.e. almost 33% of the Sudeten vascular flora. Sixty species were recognized as extinct and disappeared, 93 - as critically endangered, 161 - as endangered, 224 - vulnerable, and 12 - near threatened species. No definite kind of threat was ascribed to 34 taxa. Thus they were included in the group of ,data deficient" species. The paper presents also a quantitative analysis of all the species from the particular threat categories at the background of basic phytosociological groups. Besides, exemplary maps of the distribution of some of the Sudeten plants are given.

Abstract (sommario):

We explored the adaptability of endangered plants in degraded karst habitats through functional trait variation, using three endangered woody plants (E. cavaleriei, H. bodinieri and K. septentrionalis) in karst peak-cluster depression. We investigated the variation decomposition and correlation analysis of 13 branch and leaf functional traits using a mixed linear model, variance decomposition, Pearson’s correlation analysis, random forest regression, and generalized linear regression. The degree of variation in phosphorus concentration in the branches was the highest, while that in the carbon concentration in the leaves was the smallest. The variation in the carbon concentration in the branches and leaves, and the dry matter concentration in the leaves was mainly within species, while the variation in other functional traits was mainly between species. We found significant correlations among leaf traits, branch traits, and leaf–branch traits to different degrees; however, there were no significant correlations among branch traits in H. bodinieri. The significant correlations were higher in E. cavaleriei and K. septentrionalis than in H. bodinieri. Plant functional traits were influenced by soil and topographic factors, and the relationship between them varied by species. Our findings will enhance our understanding of the variation in leaf and branch traits in karst endangered plants and the adaptative strategies of endangered plants in degraded habitat, and will provide a scientific basis for vegetation conservation in the karst region of southwest China.

Abstract (sommario):

Gladiolus is a perennial geophyte, semi-rustice herb and belongs to the Iridaceae family. Gladiolus is an important bulbous ornamental plant. It is used as cut flowers, garden and potted plants. Turkey, which is among the major gene centers of the world and has a special place in plant genetic diversity, has rich genetic resources of geophytes including Gladiolus. However, many plant genetic resources, including Gladiolus are under genetic erosion because of the environmental and other problems and therefore face with the danger of extinction. Turkey has one Gladiolus species in IUCN Red List category. This species is Gladiolus italicus and its Red list category is Least Concern (LC). Gladiolus italicus is distributed in Macaronesia, Mediterranean basin to central Asia. Also introduced and naturalized in California. It naturally grows in many parts of Turkey. The other Gladiolus species that are reported to be under threat in Turkey are; Gladiolus anatolicus, Gladiolus antakiensis, Gladiolus halophilus, Gladiolus humilis, Gladiolus micranthus. In addition to their potential usage as ornamental plants, their usage in phytomedicine due to the medical properties of the modified stems, leaves and in other related industries increases their importance. Therefore, it is very important to protect these genetic resources of Gladiolus.

Abstract Among the 2750 species of the Polish vascular flora, about 500 species are threatened with extinction and 430 of them are strictly protected by national law. The FlorNatur project for the ex situ conservation of the most endangered species was started in 2009. The aim of the project is to collect seeds of 61 species from 161 sites in eastern Poland and store them in the Seed Bank of the Polish Academy of Sciences Botanical Garden - Center for Biological Diversity Conservation in Warsaw- Powsin. A complementary program is being carried out by the Forestry Gene Bank at Kostrzyca in western Poland. Their task is to collect 58 species from 129 natural sites in the western part of Poland. To date, seeds of 31 species from 56 populations have been collected, tested and stored in liquid nitrogen.

Abstract (sommario):

The purpose of this study was to evaluate the intraspecific variation of two endangered plant species, Fagonia cretica and Tecomella undulata, using DNA barcodes and its function in the conservation and preservation of these therapeutic plants. Fagonia cretica and Tecomella undulata are medicinal plants utilized successfully in Desi and Unani herbal treatments. Their therapeutic characteristics make them uncommon and crucial in treating liver and stomach illnesses. As a result, these plants are rapidly explored and cut to be used as herbs. They have been classified as 'Endangered Plants' by the IUCN, and additional research is necessary. The preservation and protection of biodiversity is a current study and conversation hot-button worldwide. Specifically, from arid locations, Fagonia cretica and Tecomella undulata were collected from various parts of Punjab and Sindh. It was successful in extracting genomic DNA and amplifying it using DNA barcodes. Following sequencing, BLASTn and Clustal W tools aligned their sequences. MEGA was used for the phylogenetic analysis and the evaluation of intraspecific variation. These sequences' nucleotide variations (% divergence) showed that intraspecific variation was prevalent due to the presence of these endangered plants in various locations with various environments. The findings of this study contributed to the protection of these threatened plants and helped stop their future extinction. Keywords: NCBI, BOLD, IUCN, Red List, MEGA, Phylogenetic Tree.

Abstract (sommario):

An updated checklist of Mozambique’s vascular plants is presented. It was compiled referring to several information sources such as existing literature, relevant online databases and herbaria collections. The checklist includes 7,099 taxa (5,957 species, 605 subspecies, 537 varieties), belonging to 226 families and 1,746 genera. There are 6,804 angiosperms, 257 pteridophytes, and 38 gymnosperms. A total of 6,171 taxa are native to Mozambique, while 602 are introduced and the remaining 326 taxa were considered as uncertain status. The endemism level for Mozambique’s flora was assessed at 9.59%, including 278 strict-endemic taxa and 403 near-endemic. 58.2% of taxa are herbaceous, while shrubs and trees account respectively for 26.5% and 9.2% of the taxa. The checklist also includes ferns (3.6%), lianas (1.7%), subshrubs (0.5%) and cycads (0.3%). Fabaceae, Poaceae and Asteraceae are the three most represented families, with 891, 543 and 428 taxa, respectively. The extinction risk of 1,667 taxa is included, with 158 taxa listed as Vulnerable, 119 as Endangered and as 24 Critically Endangered. The geographical distribution, known vernacular names and plants traditional uses are also recorded.

Abstract (sommario):

Quantitative assessment and evaluation of ecological parameters and biodiversity conservation are prime concerns for long-term conservation of rare and endangered species and their associated habitats in any ecological region. In this study, Gansu Province, a biodiversity hotspot, was chosen as the research area. We predicted the distribution patterns of suitable habitats for rare and endangered species. The replacement cost method was adopted to calculate the conservation value of rare and endangered species. The suitable habitat distribution area of rare and endangered wild animals reached 351,607.76 km2 (without overlapping area), while that of plants reached 72,988.12 km2 (without overlapping area). The conservation value of rare and endangered wildlife is US $1670.00 million. The high-value areas are mostly concentrated in the south and north of Gansu Province. The conservation value of rare and endangered wild plants is US $56,920.00 million. The high-value areas are mostly concentrated south of Gansu Province. The conservation value is US $58,590.00 million a year, and its distribution trend is gradually decreasing from northeast to southwest, with the highest in the forest area south of Gansu Province, followed by the Qilian Mountain area in the north. These results are of great significance for future improvement of the evaluation index system of ecosystem services and the development of ecosystem services and management strategies.
