Abstract

Climate and land-use changes are among the most relevant determinants of future persistence of rare plant species in rural landscapes. We analysed the structure of populations of a rare plant, Narcissus pseudonarcissus subsp. nobilis, and of their respective plant communities against several environmental variables (climate-, topography-, land-use-, and soil-related) in order to identify the pressures that may directly or indirectly affect the persistence of the rare species. Overall, local land-use was the primary determinant of traits related to population renewal and community composition. Specifically, traditional farmlands supported higher community diversity and population individuals. Though moderate land-use intensification seemed to benefit plant community diversity, land abandonment could allow the persistence of N. pseudonarcissus subsp. nobilis populations. Also, a relevant influence of regional environment was perceived on species richness as well as on traits related to population condition, highlighting climate change as a potential determinant of the future persistence of the species. This study highlights the importance of considering key population traits as well as of community structure to accomplish conservation goals by accounting with the factors driving changes in the habitats in which rare species occur, from climate change to land-use and landscape management.
