Management of invasive alien plants is an increasing problem throughout the world. In some cases native rare or protected species can appear or even prefer habitats dominated by invasive alien plants, which raises questions about the optimal treatment of such areas. Erythronium dens-canis in Hungary is a protected species which only have several occurrences in the country and a number of these populations situated in Robinia pseudoacacia stands developed after harvesting native forests. In this study a total of five populations of E. dens-canis were surveyed between 2020 and 2022 in southwestern Hungary examining and comparing the ongoing demographic changes under native and Robinia stands by monitoring individual plants. Two populations were situated in forests composed of native tree species, two in Robinia pseudoacacia-dominated stands and one in a Robinia-native tree species mixed stand. We categorized the plants into five age-state categories: dormant, seedling, juvenile, vegetative adult, and reproductive adult. We found some considerable differences (e.g. leaf size, reproduction rate) between the populations situated in native and in Robinia stands, whereas the population in mixed forest showed intermediate character in most examined factors. Based on our results, R. pseudoacacia have a significant effect on the phenology and life history of E. dens-canis, and this effect is greater with higher proportion of R. pseudoacacia in a forest stand where the E. dens-canis occurs.

The dramatic loss of biodiversity is caused by the use of resources and land. One strategy aiming at reducing the use of resources and land is sufficiency, which consequently could be a strategy for protecting biodiversity. This article therefore examines the extent to which sufficiency in the context of biodiversity conservation is already being addressed by nature conservation associations and the scientific community. To this end, publications were analysed firstly with regards to the understanding of sufficiency, secondly with regards to the considered links between sufficiency and biodiversity as well as thirdly with regards to the considered fields of action. The systematic identification and evaluation of scientific publications (for the years 2017–2021) and publications by German and international nature conservation associations shows that few publications address the link between sufficiency and biodiversity. And when they do, the link often remains unspecific. Possible reasons are that sufficiency potentially has broader political implications, that the term is not descriptive and that other terms are used to describe similar strategies. Other potential explanations are that several framings for the need for sufficiency are possible and that linking sufficiency and biodiversity requires interdisciplinarity. Drawing on the results and the discussion, an argument in favour of using the term ‘sufficiency’ and further research is presented. Moreover, a sufficiency typology is developed and questions are raised that could form the basis for future research on linking biodiversity conservation and the various aspects of sufficiency.

Increasing agricultural intensification, combined with land transformation and fragmentation, poses significant threats to biodiversity. While extensively cultivated landscapes serve as vital refuges against biodiversity loss, they are modified by land abandonment and intensification. Orchard meadows in Central Europe represent traditional extensive land management systems, exhibiting high biodiversity. Comprising cultivated grasslands and scattered fruit trees, orchard meadows feature structures rich in different habitats supporting a diverse flora and fauna. However, their decreasing economic importance in recent decades has resulted in severe degradation or abandonment. Despite their importance for biodiversity conservation, there remains no comprehensive overview of orchard meadow biodiversity and management in Central Europe. This review aims to summarize existing knowledge on orchard meadows’ role in biodiversity conservation and the effects of management practices on habitat diversity and quality at both smaller (structure and microhabitats, local scale) and larger scales (surrounding landscape, regional scale). The first part focuses on orchard meadow biodiversity, including both plants and animals and their link to landscape-scale factors. Biodiversity in orchard meadows is predominantly affected by patch size, determining species richness and composition, and connectivity to neighbouring orchard meadows, influencing species migration and recolonization success. The second part evaluates management impacts, illustrating differences in the benefits of mowing versus grazing across taxonomic groups. An intermediate management intensity for orchard meadows determines their conservation value in terms of species composition, varying among different taxonomic groups. To prevent area loss and abandonment of orchard meadows, we advocate for political and public support, along with incentives for farmers to maintain their biodiversity.

The Spotted Softshell Turtle (Pelodiscus variegatus) has been recognised since 2019 from Vietnam and Hainan Island, China, but little information about its population status and distribution range is currently available. The species has been provisionally listed as Critically Endangered by the Turtle and Tortoise Working Group, although the status has not been officially accepted by the IUCN, due to the threats the species is facing, including habitat loss and degradation, overexploitation for food, competition with other non-native softshell turtles and pollution. To identify conservation priority sites for P. variegatus in mainland Indochina, this study combines molecular analyses and species distribution modelling. Our results show that, in Vietnam, Phong Nha-Ke Bang National Park has the largest suitable area and high probability of species occurrence, followed by Vu Quang National Park and Song Thanh and Ke Go Nature Reserves. In addition, the central provinces, from Thanh Hoa to Thua Thien Hue in Vietnam, constitute a key part of the species distribution and should be prioritised for conservation actions. According to the study’s findings, although P. variegatus is possibly found in Laos, the probability decreases sharply at the border between both countries and there is also a gap in the occurrence of wetlands, arguing for strong natural barriers. Unfortunately, to date, only part of the species potential distribution is protected, while no records are known from protected areas, highlighting the need for extended or even new reserves. To recover natural populations of the species and following the IUCN’s One Plan Approach to Conservation, breeding programmes have been established in Vietnam with a potential to expand to other facilities in the country and abroad. Once suitable sites are identified, offspring can be released into the protected areas to improve the current conservation status of this highly-threatened softshell turtle.
斑纹软壳龟（Pelodiscus variegatus）自 2019 年起在越南和中国海南岛被确认，但目前有关其种群状况和分布范围的信息很少。由于该物种面临的威胁，包括栖息地丧失和退化、过度开发食物、与其他非本地软壳龟的竞争以及污染，龟鳖工作组已将该物种暂时列为极度濒危物种，尽管世界自然保护联盟尚未正式接受这一地位。为了确定印度支那大陆变色龟的优先保护地点，本研究结合了分子分析和物种分布模型。研究结果表明，在越南，丰芽-金边国家公园（Phong Nha-Ke Bang National Park）拥有最大的适宜区域和较高的物种出现概率，其次是武广国家公园（Vu Quang National Park）、松青自然保护区（Song Thanh Nature Reserves）和Ke Go自然保护区（Ke Go Nature Reserves）。此外，从清化省到顺化省的中部省份是物种分布的关键地区，应优先采取保护措施。研究结果表明，虽然老挝可能发现了变色龙，但在两国边境的可能性急剧下降，湿地的出现也存在差距，这说明老挝有强大的天然屏障。遗憾的是，迄今为止，该物种的潜在分布区只有一部分受到保护，而保护区内没有任何记录，这突出表明有必要扩大甚至建立新的保护区。为了恢复该物种的自然种群，并遵循世界自然保护联盟的 "一个计划保护方法"，越南已经建立了繁殖计划，并有可能扩展到国内外的其他设施。一旦找到合适的地点，就可以将后代放归保护区，以改善这种濒临灭绝的软壳龟目前的保护状况。

This study focuses on the development of the landscape during a period of significant social changes in Central Europe from the middle of the 20th century, and evaluates the impact of the selected natural factors on landscape dynamics in the Snohy dispersed settlement area (cadaster of Hriňová, Slovakia). During the periods of feudalism and the democratic Czechoslovak Republic after 1918, private ownership of land prevailed on the territory of Slovakia. After 1948, in the period of the socialist establishment, the municipality was one of the few localities without collectivisation. We focused on the state and changes to the landscape structure based on remote sensing data analysis (1949, 2003, and 2018), as well as field research and archive photographs inspection. The study area is a part of the proposed Special Area of Conservation SKUEV4026 Meadows of Poľana and is situated near the border between the transition and buffer zones of the Poľana Biosphere Reserve. The state of land cover and its changes have been evaluated using a CORINE Land Cover modification at the 5th level. Results showed that the influence of the slope on agricultural extensification, deforestation, and afforestation, was the most pronounced. Since 1949, more than half of the land cover has changed across the study area. The most extensive changes were recorded in the spatial structure and composition of forest communities.

Eremias argus, known as the Mongolian racerunner, is a reptile that has been designated as a level II endangered species in South Korea since 2005 despite being listed as “Least Concern” by the International Union for Conservation of Nature. Particular vegetation and soil characteristics are critical components of the habitat of E. argus, which is an ectotherm. However, research on the environmental characteristics of E. argus living on a fluvial island is lacking. This study sought to characterize the soil environmental factors and vegetation composition of E. argus habitats on Doriseom Island, South Korea by dividing the island into an area in which E. argus occurred frequently (F zone) and an area in which E. argus occurred rarely (R zone). Both soil hardness and cobble cover were significantly higher in the R zone (soil hardness: 1.6 ± 0.2 kg‧cm-2, mean ± standard error; cobble cover: 40 ± 5%) than in the F zone (soil hardness: 0.9 ± 0.1 kg‧cm-2; cobble cover: 18 ± 3%). Plant litter cover did not differ significantly based on E. argus occurrence. The vegetation composition within F and R zones appeared distinct, though Coreopsis lanceolata dominated both zones. A sand dune sedge, Carex pumila, thrived in F zone sites, where soil hardness was low, while the endemic Aster danyangensis, which prefers cobble areas, was found largely in the R zone. In conclusion, E. argus was most commonly found in areas with low soil hardness dominated by dune vegetation. Understanding endangered species’ habitat requirements can provide important clues for establishing conservation plans and restoration measures.
Eremias argus，又名蒙古匐行者，是一种爬行动物，尽管被国际自然保护联盟列为 "最不关注 "物种，但自 2005 年以来，韩国一直将其列为二级濒危物种。特定的植被和土壤特性是外温动物 E. argus 栖息地的关键组成部分。然而，目前还缺乏对生活在河流岛屿上的箭鱼环境特征的研究。本研究试图通过将韩国多里逊岛划分为经常出现箭毒的区域（F 区）和很少出现箭毒的区域（R 区），来描述箭毒栖息地的土壤环境因子和植被组成特征。R 区的土壤硬度和卵石覆盖率都明显高于 F 区（土壤硬度：1.6 ± 0.2 kg‧cm-2，平均值 ± 标准误差；卵石覆盖率：40 ± 5%）：40 ± 5%）高于 F 区（土壤硬度：0.9 ± 0.1 kg‧cm-2；卵石覆盖率：18 ± 3%）。根据 E. argus 的出现情况，植物枯落物覆盖率没有明显差异。F 区和 R 区的植被组成似乎各不相同，但这两个区都以拟南芥为主。沙丘莎草（Carex pumila）在土壤硬度较低的 F 区生长茂盛，而特有的丹阳翠菊（Aster danyangensis）喜欢在卵石区生长，主要分布在 R 区。总之，E. argus 最常见于以沙丘植被为主的低土壤硬度地区。了解濒危物种对栖息地的要求可为制定保护计划和恢复措施提供重要线索。

A significant proportion of Europe’s species-rich grasslands are semi-natural habitats. They have a long history of traditional management. Several studies have been carried out to conserve them, resulting in the establishment of subsidised conservation management schemes. On the other hand, many of these conservation management schemes have failed to provide locally adaptive solutions to maintain the diversity and functional status of species-rich grasslands. In addition, few studies have compared the conservation effectiveness of different levels of management complexity. The levels of management complexity in our study are based on how different management types (e.g. grazing and mowing etc.) and how different herbage removal intensities (e.g. lower and higher grazing intensities) are combined within and between years. To investigate this, we compared the overall effects of management complexity, herbage removal intensity and management type on plant diversity, plant functional type dominance relationships and plant physiognomy. Our field sampling was carried out in the sandy meso-xeric grasslands of the Turján Region of the Great Hungarian Plain (Central Hungary). We sampled nine 2 m × 2 m plots per grassland site (n = 12), recorded all the rooted plant species and estimated their percentage cover in each plot. High level of management complexity had significant positive effects on plant diversity, grazing had positive effects on plant diversity and phanerophyte density, while the studied levels of herbage removal intensity had no effect on diversity, plant functional types or plant physiognomy. In parallel, mowing and/or low levels of management complexity had some negative effects on conservation value (e.g. lower Shannon and Simpson diversity). In this landscape, the dominance of grazing and the more complex management is more optimal than relatively homogeneous mechanical mowing. The choice of management type and intensity is an important tool in the conservation management system of this landscape, but so too is its appropriate application in space and time. Through a detailed analysis of the effects of management complexity levels compared to management types and herbage removal intensity levels, we provide a new opportunity to make grassland management practices more effective for conserving biodiversity in this region, but it would be important to investigate these in different landscapes and conditions.
欧洲物种丰富的草地中有很大一部分是半自然栖息地。它们有着悠久的传统管理历史。为了保护它们，已经开展了多项研究，并制定了有补贴的保护管理计划。另一方面，许多这些保护管理计划未能提供适应当地情况的解决方案，以维持物种丰富的草地的多样性和功能状态。此外，很少有研究对不同管理复杂程度的保护效果进行比较。我们研究中的管理复杂性水平是基于不同的管理类型（如放牧和刈割等）以及不同的除草强度（如较低和较高的放牧强度）在年内和年际之间的组合方式。为此，我们比较了管理复杂性、除草强度和管理类型对植物多样性、植物功能类型优势关系和植物相貌的总体影响。我们在匈牙利大平原图尔扬地区（匈牙利中部）的沙质中干草原上进行了实地取样。我们在每个草场取样九个 2 m × 2 m 的小块（n = 12），记录了所有生根植物物种，并估算了它们在每个小块中的覆盖率。高水平的管理复杂性对植物多样性有显著的积极影响，放牧对植物多样性和植物密度有积极影响，而所研究的除草强度水平对多样性、植物功能类型或植物形态没有影响。与此同时，刈割和/或低水平的管理复杂性对保护价值产生了一些负面影响（例如，香农和辛普森多样性降低）。在这一景观中，放牧占主导地位和更复杂的管理比相对均匀的机械刈割更理想。管理类型和强度的选择是该景观保护管理系统的重要工具，但其在空间和时间上的适当应用也同样重要。通过详细分析管理复杂程度与管理类型和除草强度的对比效果，我们提供了一个新的机会，使草地管理方法更有效地保护该地区的生物多样性。

Green areas are important places for biodiversity conservation within cities, but their vegetation is affected by various anthropogenic factors. This study used an exploratory approach to examine the influence of urbanisation and air pollution-related factors on the indicators for the composition and structure of vegetation in an urban area in northeast Mexico. Based on the spatial analysis of the major air pollutants, four sampling categories were delimited (rural, low, moderate and high urbanisation). The differences between categories, based on vegetation structure, were determined using non-parametric Kruskal-Wallis tests. The Importance Value was calculated for the species. The floristic similarity was compared using NMDS and PERMANOVA unidirectional. The relationship between environmental variables and abundance of species was evaluated using CCA. One hundred and ten plant species were collected, including ten alien species. The highest abundance and species richness were registered in the rural site. The general tendency of vegetation structure is to plants decreasing with respect to the increase in the levels of urbanisation and air pollution present in the study area. The association between the environmental variables and plant communities along the urbanisation gradient was significant, being the relative humidity, the particles lower than 2.5 μm, the dew point and the heat index as the most important variables. The understanding of the nature and variability of vegetation within green areas contributes to increasing our knowledge about the distribution of the environmental services they provide and the composition of the faunal communities that depend on them. For this reason, this study relates the plants of a specific area of northeast Mexico with the environmental quality present in an urban area.

Cultivated and suburban areas are usually considered unfavourable to the vulnerable components of biodiversity and regarded as not interesting from a conservation point of view. However, remnants of semi-natural vegetation can be embedded in such areas, becoming possible refuges for wild biodiversity despite the high anthropogenic pressures. With the present study, we raise awareness that, in some cases, these areas can be regarded as biodiversity treasure chests, even when apparently poor and with low appeal for conservationists. We demonstrate the importance of urbanised and cultivated landscapes by providing new records of two lepidopteran species rare for the Italian Peninsula, namely Amphipyra (Pyrois) cinnamomea and Boudinotiana notha. The European range of A. cinnamomea has become strongly reduced, seeming extinct in some Central European regions and the few Italian records mostly date back several decades. B. notha has very few relict populations in Mediterranean Europe, some of which are in peninsular Italy, where it is threated by urbanisation and reduced precipitations expected in the next decades. Our findings confirm the importance of small and highly fragmented patches of semi-natural vegetation for biodiversity conservation, as they can allow species of conservation interest to persist in hostile lands.
