Abstract
Investigations of dune habitats in Montenegro led to the discovery of 8 taxa new for the country: Avellinia festucoides, Corynephorus divaricatus, Isoetes histrix, Juncus tenuis, Medicago doliata, Myosotis laxa ssp. cespitosa, Setaria parviflora, and Solenopsis laurentia ssp. gasparrinii. Of particular importance are Solenopsis laurentia ssp. gasparrinii (not yet been recorded in the SE Adriatic) and Isoetes histrix (doubtfully reported for Albania). Since only one or small number of additional localities are expected in Montenegro, species are proposed as candidates for the national list of legally protected species: Isoetes histrix, Solenopsis laurentia ssp. gasparrinii, Avellinia festucoides and Corynephorus divaricatus. According to the IUCN criteria, the Isoetes histrix, Solenopsis laurentia ssp. gasparrinii and Corynephorus divaricatus are assessed as CR, while Avellinia festucoides as EN. Monitoring and eradication measures are proposed for alien species (Setaria parviflora and Juncus tenuis), especially for the second one, which is considered invasive.
