Alien and rare plants tend to adapt to contrasting biotic and abiotic conditions. However, adaptability assessments of alien and rare plants using biological and habitat characteristics in stressful and disturbed environments are limited. We collected and demonstrated the biological and habitat characteristics and assessed the adaptive capacity of alien and rare plants in China using the analytic hierarchy process. Biological characteristics, such as dispersal strategy, sexual and asexual reproduction modes, life form, and habitat characteristics (e.g., habitat type and distribution spatial extent), are important indicators of the adaptability of alien and rare plants to stressful and disturbed environments. Alien plants have a higher adaptive capacity to disturbed environments than rare plants, while rare plants have a higher adaptive capacity to stressful environments than alien plants. Stressful and disturbed environments constrain the adaptive capacity of alien and rare plants, respectively. However, the constraint on alien plants from stressful environments is weaker than that on rare plants from disturbed environments. Understanding the adaptive capacity of alien and rare plants will help researchers and policymakers develop strategies for preventing the invasion of alien plants as well as protecting rare and endangered plants.

In the beautifully-illustrated book of rare and threatened plants of Greece (Phitos et al. 1995), the selection of species is based strictly on the four World Conservation Union (IUCN) categories of ‘extinct’, ‘endangered’, ‘vulnerable’ and ‘rare’ (Lucas & Synge 1978). The Swedish ‘red data’ book of plants (Aronsson et al. 1995) adds ‘care-demanding species’ to the list. Five percent of the total number of vascular plant species in Greece are included in the Greek book, while 23% of the vascular plant species in Sweden are in the Swedish book. This latter percentage may appear to be sufficiently large, but is it?

Rare earth elements (REEs) form a chemically uniform group with very similar physical and chemical properties. The REEs include the elements scandium, yttrium, and the lanthanides from lanthanum to lutetium. They are widely distributed and present in all parts of the biosphere. REEs are required in industry, agriculture, medicine, biotechnology, environmental problems and many other fields. Lately, many experiments show their positive or negative, first of all nonspecific, effect on life processes of higher plants as well as growth and yield of cultivated species, but the physiological mechanisms are still not well understood. It has been determined that yttrium is widely distributed in plants, as well as that certain plant species uptake yttrium at different extent. Its highest accumulation is in the root and the leaf. Although yttrium was discovered more than two centuries ago, its effect on higher plants - their anatomical and morphological built, physiological and biochemical processes etc. - is very little known. One of the basic reasons is that yttrium, as well as other REEs elements, according to current knowledge, is not biogenic for higher plants and - wider - for live organisms. The objective of this paper is to concisely show previous knowledge about yttrium in the plant world.

AbstractThe forests of the Kilum-Ijim area, around Mount Oku in West Cameroon, are the largest remaining patch of montane forest in West Africa, and the highest in altitude. This important habitat harbours endemic species of both animals and plants but is surrounded by a high density of human settlements: c. 300,000 people live within a day's walk of the forest, which covers only 200 sq km. BirdLife International and the Ministry of the Environment and Forestry, Government of Cameroon, are currently operating the Kilum-Ijim Forest Project, with the overall goal of conserving representative areas of the Cameroon montane forest biome in the long-term. The purpose of the project is toensure that the biodiversity, extent and ecological processes of the Kilum-Ijim Forest are maintained and that the forest is used sustainably by the local communities. The existence of a small Sphagnum community and associated wetland plant species was discovered in 1997 on the summit of Mount Oku, at 2900 m. This site is of extremely high conservation importance because several plant species endemic to the Kilum-Ijim area have been recorded there. In addition, it is the highest Sphagnum bog and the source of the highest stream in West Africa.

This study aims to identify rare medicinal plants in Manggeh Village, Karanganyar District, Karanganyar Regency, as well as to understand the level of knowledge and understanding of the community regarding rare medicinal plants in areas with a low tendency. The research method used was field surveys, interviews, and direct observation of 40 respondents who were randomly selected from people in low inclined areas. The results showed that there were a number of rare medicinal plants in Manggeh Village. These plants have high medicinal potential and have been used traditionally by the local community. However, the level of public knowledge and understanding regarding rare medicinal plants is still limited. Although some people are familiar with rare medicinal plants in general, in-depth knowledge about their benefits, uses and potential side effects is still limited. This research provides a deeper understanding of the biodiversity in Manggeh Village and provides useful information for the community in the proper and responsible use of medicinal plants. The results of this study can also be a basis for local governments in developing policies for the conservation of rare medicinal plants.

A literature survey has been completed in order to determine plant species that have been considered rare, and also plant species that are potentially rare. Dr. Stan Welsh of the Botany and Range Science Department of Brigham Young University (Provo, Utah) was contacted personally during the field season. His experience in the region has provided a list of additional species that are considered rare for the state of Utah and occur on specific sites near the National Park (Table 1). It is possible that these additional rare species may occur within the boundaries of the park.

This work presents the structural analysis of rare medicinal plants of the flora in Tatarstan, Russia. The wild medicinal flora of Tatarstan includes 357 species, 9.5% of which have the status of protected plants. In Tatarstan, the protected species belonging to the subkingdom Higher spore plants are represented by two classes, two families and three genera. Protected Seed plants include Gymnosperms, represented by one class and one family, but the basis of the flora is formed by Angiosperms, including two classes, 15 families and 30 species. The most numerous families of rare plants in Tatarstan are Orchidaceae and Ericaceae. All representatives of this family are tuberiferous plants. Limited vegetative propagation leads to the reduction in species abundance. Plants of the family Ericaceae are confined to the ecological-cenotic group of oligotrophic plants, the distribution of which is associated with rare communities of sphagnum bogs. In general, on the territory Tatarstan, the composition of protected medicinal plants is dominated by wetland species. Among rare plants, more than 40% are located on the border of their range. However, the most common limiting factor for rare and endangered species is the direct or indirect influence of human activities on the natural habitats of medicinal plants.

The article presents the results of long-term surveys of urban green spaces (Moscow) with the allocation of rare tree species. We consider rare tree species to be those that can be placed as points on the city map and can be counted individually depending on the number of specimens presented. This study did not take into account rare specimens available in arboretums, Botanical gardens, and other scientific collections in the city, but only those that are available in public places. Private gardens were also not considered, but only those that have free access to public spaces were considered. After identifying rare species, their sanitary and aesthetic condition was determined and conclusions were made about the prospects for their use in other landscaping objects.

The future of Australia's flora is dependent upon developing an understanding within the community and management of the need for conservation. A vital ingredient in achieving this understanding is the provision of accurate information on how many species are threatened or have already become extinct. Rare or Threatened Australian Plants (ROTAP): 1995 Revised Edition fulfils such a need and represents an up to date list of taxa that are presumed extinct, endangered, vulnerable, rare or poorly known at the national level.

With declining availability of funds for recreational-related construction, communities are searching for innovative ways to receive funding. To have a better chance of receiving funding for the construction of a sports complex and to create a sanctuary for the federally endangered plant, the Texas poppy-mallow (TPM), a partnership was formed among city, county, state, and federal agencies, and private landowners. As a result, Mitchell County was awarded $441,000 from the Texas Parks and Wildlife Outdoor Recreation Matching Grant Program and Partners for Fish and Wildlife to build a 20-acre sports and recreation complex. Funds were awarded, in large part, because Mitchell County created a sanctuary for the TPM. This partnership also represents the first endeavor to restore the TPM.

Resumo:

Abstract. Species reintroduction is one of the most important tasks for biodiversity conservation. In the Samara region, the Department of Ecology, Botany, and Nature Protection of Samara University is constantly working to return rare plants to their natural habitat. Field surveys are carried out to monitor the process of plant development in the natural environment. However, the complex terrain and the special conservation status of the territories, where reintroduction is carried out, require the development of methods for monitoring plants that reduce human contact with the natural environment. As such a method, the article proposes using data from unmanned aerial vehicles (UAVs) in conjunction with the detection of reintroduced plant species using object detection neural networks, namely YOLOv3. The proposed method reduces the anthropogenic impact on the territory during the monitoring process and simplifies plant observations.
