“…The geographical distribution of H. caput-felis was determined through field surveys during 2012–2017 in all localities for which there were herbarium specimens or database records (Supplementary Table 1) and/or published data (Agulló et al, 2010; Fenu et al, 2015b; Sulis, 2016). Additionally, all sites along the coasts of Sardinia, the Balearic Islands and the Mediterranean coasts of Spain and Morocco with suitable ecological conditions for the species were surveyed.…”

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.

“…Its flowers are hermaphrodite and have a short lifespan (3-4 days; Rodríguez-Pérez 2005). The flowering period is from March to June, and the fruiting season runs from late April to the beginning of August (Fenu et al 2015;Sulis et al 2017). H. caput-felis is an entomophilous, mostly self-incompatible, plant species (Agulló et al 2015).…”

“…Fruits are capsules that detach at maturation, and seed germination takes place in autumn, at the onset of the rainy season (Rodríguez-Pérez 2005). Seeds exhibit a high germination rate after scarification (Rodríguez-Pérez 2005;Sulis et al 2017).…”

“…The chosen continuous state variable for evaluating the demographic dynamics of the H. caputfelis populations was plant size (i.e. plant volume, hereafter), which has been demonstrated to be positively correlated with its reproductive capacity (Fenu et al 2015;Sulis et al 2017), following the same approach in Sulis et al (2018).…”

Demographic analysis of plant populations represents an essential conservation tool allowing to identify the population trends both at global and at the local level. In this study, the population dynamics of Helianthemum caput-felis (Cistaceae) was investigated at the local level by monitoring six populations distributed in Sardinia, Balearic Islands and Ibero-Levantine coast (Alicante). Demographic data for each population were analysed by performing Integral Projection Models (IPMs). Our results showed that, although the local trend of the main basic demographic functions was similar, vital rates and demographic dynamics varied among populations indicating high variability. In fact, asymptotic growth rate in Spanish populations widely varied both between years and populations (some populations growth, decline or strongly decline), while Sardinian populations showed greater equilibrium or a slight increase. Also, the typical pattern of a long-lived species was not supported by the results at the local scale. These results indicated that different populations of the same species can present extremely different population dynamics and support the belief that, for conservation needs, local studies are more informative than global ones: the conservation status of H. caput-felis could notably vary at a small spatial scale and, accordingly, the conservation efforts must be planned at the population level and supported by local analysis.
