Preliminary Red List of charophytes in Serbia

According to the latest checklist, updated in December 2022, 25 species of charophyte algae are registered on the territory of Serbia. These data are gathered in a number of projects and finally integrated within the project related to the production of Red books and Red Lists of flora, fauna and fungi on the territory of the Republic of Serbia. The crown results of this work are preliminary Red Lists for all organism groups, including charophyte algae. The lists were produced in accordance with IUCN criteria, using an application especially created for the purpose of this project. According to IUCN criteria, all charophyte species registered on the territory of Serbia are Red Listed, that is, belong to one of the three categories – Critically Endangered (CR) – ten species, Endangered (EN) – seven species, and Vulnerable (VU) – seven species, except one species which is Data Deficient. The main factors endangering the flora of charophytes in Serbia are habitat fragmentation and desiccation, which were accordingly used as the main criteria to assess charophyte species status. Here we present the process as well as the results of the assessment and discuss the main factors of endangerment.23rd Meeting of the Group of European Charophytologists (GEC), August 16 – 19, Riga, Latvi
