“…Unfortunately, no comprehensive monitoring has been conducted so far. In available publications, we found only information on the impact of lake level on the condition of the Amur softshelled turtle (Pelodiscus maackii (Brandt, 1857)) (Maslova 2016, Bazarova et al 2022, Maslova et al 2023) and on commercial fish stocks (Zuenko et al 2020). Data on the impact of flooding and waterlogging on vegetation cover and flora composition, including the state of populations of Oxytropis chankaensis Jurtzev, a rare psammophyte species, are extremely scarce, fragmentary and largely incomparable (Bazarova et al 2022, Kozhevnikova & Maslova 2022.…”

Lake Khanka is the largest freshwater body of water in northeast Asia, with a basin of about 25 000 km2. The hydrological regime of the lake is cyclical in nature due to various factors affecting water inflow and outflow. The last increase of water level in the lake began in the 2000s and by 2015 reached the maximum value of 416 cm (with the average annual level of 293 cm). A steady decline in water level has been observed since 2021. To assess the diversity and structure of coastal plant communities on the sandy-pebbly substrate along the western shore of Lake Khanka and their dynamics under the influence of flooding, we laid 20 transects and performed descriptions at seven sites, including two sites in the protected area of the Cluster Sosnovy of the Khanka Nature Reserve. Using the diversity and similarity/difference indices, plant communities were compared across the sites. It was shown that their heterogeneity is due to the diversity of both aboriginal and adventive species. In protected areas, the role of adventive species is significantly lower than in recreational areas. The five dominant species in the communities account for 50 % or more of the total abundance. Vegetation groupings in the three identified zones, which have been inundated for different periods of time, have a similar diversity, with differences due only to the native fraction of species. The second zone, characterized by the greatest influx of species of different ecological and cenotic groups during water recession, differs in species richness. The obtained data show for the first time the diversity and structure of coastal plant communities of the sandy-pebble beech of the western coast of Lake Khanka and reflect some processes of its dynamics in connection with the long-term standing water. For more successful coverage of the issues raised, long-term monitoring on the laid transects, at least covering one 20–30-year cycle of the dynamics of the hydrological regime of Lake Khanka, is necessary.

“…The Slender racer ( Orientocoluber spinalis ) is a rare, yet widely distributed colubrid snake, occurring across the Korean Peninsula, China, Russia, Mongolia, and Kazakhstan 29 , 30 . This species has a low abundance in fragmented habitats and is only observed in few protected areas in these countries 31 – 33 . As a result, ecological information on O.spinalis is globally scarce despite its wide distribution.…”

“…As a result, ecological information on O.spinalis is globally scarce despite its wide distribution. In addition, Russia 31 , Mongolia 32 , and Kazakhstan 33 , 34 even classified this species as threatened species. Nevertheless, the most recent assessment made by the IUCN on O. spinalis classified the species as Least Concern 35 , thus not reflecting the apparent rarity of the species across its geographic distribution.…”

Conservation assessments are essential for preserving biodiversity. However, many reptile species have not been evaluated owing to data deficiencies. The Slender racer (Orientocoluber spinalis) is threatened in four out of six inhabiting countries. However, despite its apparent rarity and data deficiency, the International Union for Conservation of Nature (IUCN) has classified it as a Least Concern. In this study, we combined field surveys, habitat analysis, and ecological niche models (ENMs) to identify the critical habitat characteristics of O. spinalis, evaluate its distribution status in the Republic of Korea, and register it as a nationally endangered species. Across the country, we found a few small populations on the mainland but large populations on the islands. Orientocoluber spinalis is mainly found in low-altitude ecotone habitats between grasslands and forests. Based on previous genetic and climatic studies, we propose designating it as an endangered species to conserve this species in protected areas such as national parks, and its non-isolated mainland populations can be preserved as source populations.
