The assessment of the conservation status of a species is the first step in developing a conservation strategy. IUCN Red Lists assessments are an important starting point for conservation actions and the most commonly applied method for assessing the extinction risk of a species. In this study, the global conservation status of the rock rose Helianthemum caput-felis Boiss. (Cistaceae), a perennial Mediterranean plant, was evaluated using the Red List criteria. The distribution of the species was determined by monitoring historical localities and all other suitable sites along the western Mediterranean coasts for 6 years. For each confirmed locality, the ecological and population parameters and the main threats were recorded; these data were used in a quantitative analysis of the species' extinction risk. Our findings indicate there have been several recent extinctions, and there is a continuing decline in the species' area of occurrence, habitat quality and number of reproductive plants. The main threats are related to human activities. Extinction models indicate a probability of quasi-extinction risk of c. 30% in five generations or c. 45% in three generations, with the species likely to become extinct in seven currently known localities within the next 10 years. Application of the Red List criteria indicates H. caput-felis should be categorized as Endangered. This study confirms that legal protection and passive conservation measures are insufficient to guarantee the persistence of a plant species. Active conservation and management actions are needed to protect this and other threatened species of the Mediterranean Basin.

评估岩蔷薇 Helianthemum caput-felis 的全球保护状况

评估一个物种的保护状况是制定保护策略的第一步。IUCN 红色名录评估是保护行动的重要起点，也是评估物种灭绝风险的最常用方法。在这项研究中，岩石的全球保护状况上升向日葵博伊斯。（Cistaceae）是一种多年生地中海植物，使用红色名录标准进行了评估。该物种的分布是通过对地中海西部沿岸的历史地点和所有其他合适地点进行为期 6 年的监测来确定的。对于每个确认的地点，记录了生态和人口参数以及主要威胁；这些数据被用于对该物种灭绝风险的定量分析。我们的研究结果表明，最近发生了几次灭绝，并且该物种的出现面积、栖息地质量和繁殖植物的数量持续下降。主要威胁与人类活动有关。灭绝模型表明 c 的准灭绝风险的概率。五代或 c. 30%。三代45%，该物种可能在未来 10 年内在七个目前已知的地区灭绝。红色名录标准的应用表明H. caput-felis应归类为濒危。这项研究证实，法律保护和被动保护措施不足以保证植物物种的持久性。需要采取积极的保护和管理行动来保护地中海盆地的这一物种和其他受威胁物种。
