Abstract The deterioration of conservation status of ecosystems, loss of habitats and extinction of species call for actions to halt these negative processes. The starting point is to determine the threat status of specific nature components which may be achieved, for example, by the development of red lists. This paper presents the current threat status of natural habitats listed in Annex I to the Habitats Directive (HD) in Poland. Threat categories were based on the International Union of Conservation of Nature (IUCN) division, while threat status assessment of habitats was carried out using a simple method taking into account limitations resulting from the quality of available data. The assessment was based on four criteria: Current habitat area of occupancy, area trend, habitat structure and function status and sum of pressures to habitat. Data were derived from reports on the conservation status of natural habitats in alpine and continental bioregions, submitted to the European Commission (EC) in 2019. Out of 77 habitats, 2 and 8, respectively, were classified as Critically Endangered (CR), 5 and 19 as Endangered (EN), 10 and 23 as Vulnerable (VU), 15 and 18 as Near Threatened (NT) and 8 and 2 as Least Concern (LC). In the alpine region, the largest share of CR + EN habitats was in the habitat group of water habitats, grasslands and heaths and shrubs. In the continental region, only in the habitat group of forests were there no CR or EN habitats, and the degree of threat to habitats was significantly higher than in the alpine region. Threats to natural habitats in the alpine region most often result from their small area and the tendency to area decline. On the other hand, in the continental region, habitat structure and function distortions, strong environmental pressure and small area equally contribute to habitat threat.

波兰自然 2000 栖息地类型红色名录

摘要 生态系统保护状况的恶化、栖息地的丧失和物种的灭绝要求采取行动制止这些负面过程。起点是确定特定自然成分的威胁状态，这可以通过例如制定红色清单来实现。本文介绍了波兰栖息地指令 (HD) 附件 I 中所列自然栖息地的当前威胁状况。威胁类别基于国际自然保护联盟 (IUCN) 部门，而栖息地的威胁状态评估是使用简单的方法进行的，同时考虑到可用数据质量造成的限制。评估基于四个标准：目前居住的栖息地面积、面积趋势、栖息地结构和功能状态以及栖息地压力总和。数据来自于 2019 年提交给欧盟委员会 (EC) 的关于高山和大陆生物区自然栖息地保护状况的报告。在 77 个栖息地中，分别有 2 个和 8 个被列为极危 (CR)，5 19 为濒危 (EN)，10 和 23 为易危 (VU)，15 和 18 为近危 (NT)，8 和 2 为最不关心 (LC)。在高山地区，CR + EN 栖息地的最大份额是在水栖息地、草原、荒地和灌木的栖息地组中。在大陆地区，仅在生境组森林中没有CR或EN生境，对生境的威胁程度明显高于高寒地区。对高山地区自然栖息地的威胁最常见的原因是它们的面积小和面积下降的趋势。另一方面，
