E THNOBOTANY has improved dramatically in recent decades and become a widely recognized scientific discipline after the usage of mathematical methods. Cultural importance index (CI) is considered a tool for evaluating the use-value (UV) of plants. It become an essential quantitative method in many ethnobotanical studies. The present study evaluates the cultural significance of different Egyptian endemics using four indices (UR: number of use reports, RFC: relative frequency of citation, RI: relative importance and CV: cultural value) depend on informant report. Each index intends to evaluate the CI of plant taxa and its statistical analysis. Ethnobotanical information was collected from summer 2018 to Spring 2020 through monthly visits to the study area. CI was applied on 41 endemic plants recorded in the Egyptian flora. Medicinal species were the most represented group (40 taxa), then grazing (25), and human food ( 14). Ranking of CI index according to the contribution of each species indicating that Rosa arabica was the first-ranking (6 out of 9 groups), followed by Origanum syriacum subsp. sinaicum (5 groups) and Sonchus macrocarpus (3 groups). High positive linear correlation was detected between CI-RFC (0.96), CI-RI and CI-CV (0.98); while weak correlation between number of uses (NU) and RFC (0.47) at P<0.05 (n=41).

“…The threats are classified into 8 major groups: over-collecting and over-cutting, habitat loss, browsing and over-grazing, clearance for agriculture, mining and quarrying, trampling, urbanization and tourism and climatic changes and environmental conditions. Major threats for each taxon were assessed in the field and by using the website (http://www.iucnredlist.org/technical-documents/classification-schemes/threats-classification-scheme) and depending on the following studies:Hosni et al (2013),Shabana (2013),Zahran et al (2015),Rabei et al (2016),Shaltout et al (2018),Omar and Nagy (2015), The IUCN Red List of Threatened Species (2017a, 2017b, 2017c),Omar et al (2017), Omar (2018.…”

Background: Endemic species are important components in the flora of most world regions. Most of these species have become threatened and exposed to extinction within the last few years. The present study aims to evaluate the ecosystem services offered by the endemic plant taxa in Egypt and the threats that affect them. Twenty-five field visits were conducted during summer 2018 to spring 2022 to several locations all over Egypt. In each location, the main habitats, national distribution, abundance, goods and threats were recorded. Results: Egypt has 41 endemic taxa belonging to 36 genera and 20 families inhabiting 10 main habitats. Rocky surfaces and sandy formations have the highest number of endemic species. The relation between the number of endemic taxa and the abundance categories indicated that 2 taxa are rare (4.9% of the total taxa), while the remaining were very rare (95%). The most represented offered good was the medicinal uses (32 taxa = 78%), while fuel plants were only represented by 2 taxa (2 taxa = 4.9%). Besides, 14 taxa (34.1% of the total studied taxa) have at least 1 environmental service. Soil fertility (7 taxa = 50%) was the most represented, followed by sand accumulations (6 taxa out of 14 taxa = 43%), while shading plant was the least (1 taxon = 7.1%) (Rosa arabica). The most represented threat is over-cutting and over-collecting (38 taxa = 92.7%), while mining and quarrying is the least represented (4 taxa = 9.8%). Conclusions:The potential and actual goods, services and threats of the endemic taxa were assessed as follows; field observation, information collected from local inhabitants and herbalists, and a literature review. The present study recommended planning a strategy about the importance, threats and conservation of endemic taxa in Egypt that would help in the protection and rescue of these plants and increase awareness about the importance of these plants.
