“…The primary mechanism to escape from the negative effects of climate and habitat change is dispersal. Similarly to other Vicia species (e.g., Oleas et al 2018), in the case of V. biennis, short-distance dispersal (for a few meters) is achieved by the explosive opening of mature fruits and the ejection of seeds (called "ballochory") (A. E., personal observation), but other mechanisms of dispersal are unknown. However, maintaining a large, persistent and highly dormant soil seed bank may be an appropriate strategy to avoid unfavourable conditions, not in space but in time.…”

We aimed to investigate the reproduction-related traits of Vicia biennis L., an endangered and poorly known wetland species in its western marginal populations (in Hungary), and discuss the conservational and ecological implications. We measured the mass, viability, and physical dormancy of half-year-old seeds in five in-situ collected seed lots, while potential seed longevity (i.e., seed bank type) was estimated from repeatedly germinating subsamples from four ex-situ collected seed lots for 3–8 years. Plant survival, flowering, and seed production were studied in different light-, irrigation-, and competition conditions in a botanical garden experiment. We found that 1) half-year-old seeds have a high germination capacity (78–100%), 2) and high level of physical dormancy (72–100%) in all examined Hungarian populations, and 3) the seeds can preserve their germination capacity for more than five years, although their viability sharply decreases, probably falling below 10% within ten years, when they are stored at room temperature. The results of the botanical garden experiment suggested that 1) the species is annual, not biennial; 2) it shows strong sensitivity to precipitation and low competitiveness for water; and 3) it can produce hundreds of seeds even in suboptimal (dry or shady) conditions. Although the species was found to be well-adapted to a temporally heterogeneous environment, its future vulnerability can increase depending on the duration of dry seasons. Further investigation of genetic diversity and soil seed bank is needed to estimate the actual vulnerability of the species while strengthening the populations through seed sowing, and additional vegetation control in the habitats is suggested.

“…This reserve has existed for more than 30 years and has made it possible to preserve the ecological balance and the diversity of biota at a sufficiently high level. For the effective existence of the tract, constant monitoring of the level of flora diversity is necessary [2], since the reserve is botanical for the purpose of its creation, and the flora as a whole forms the basis of any ecosystem. Of particular importance is the assessment of relict species that are present on the territory of the reserve [3,4].…”

Monitoring assessment of the state of conservation area is a relevant and important direction in ecology. However, not all parameters of the ecological balance are checked by state services. The wide scale of specially protected areas also makes it difficult to analyze them in detail by all indicators. Therefore, it is significant to conduct a comprehensive study of such sites locally, taking into account the diversity of environmental sustainability indicators. The paper analyzes the biological diversity of flora within one of the reserves of the Belgorod region, with an emphasis on the state of tree species. The morphological assessment of the discovered species and their ecological characteristics are given. The influence of the industrial zone of the adjacent territories on the vegetation of the reserve and the microbial equilibrium of the soil cover was evaluated. In general, the ecological state of the flora is assessed as good; the microbial composition corresponds to the typical for chernozem soils. At the same time, recommendations are given for further monitoring of biodiversity indicators in this area, in order to maintain the ecological balance, preserve the species composition of vegetation and the diversity of the soil microbial community.
