Tomorri National Park in Albania is characterized by diverse climate and geological conditions which are reflected in rich flora and habitats. Particularly in calcareous rocky habitats above the timberline, a high presence of rare and endangered plant species is observed. Several typical alpine and scardopindic species such as Linaria alpina, Scabioza graminifolia, Veronica thessalica and many endemic species of the Balkan area such as Achillea fraassi, Asperula doerfleri, Crataegus heldreichii, Crepis baldaccii are distributed in the Southern and Western regions of the Park. Other subendemics species such as Campanula hawkinsiana, Centaurea epirota, Edraianthus australis, Nepeta spruneri, Viola albanica share their habitats between Greece and Albania, while the Albanian endemics like Euphorbia cikaea, Astragalus autranii, Onosma mattirolii, Arenaria cikaea occur only above the tree line of Pinus heldreichii forest in Tomorri Mountain. Common plant species and also some endangered species such as Satureja montana, Sideritis raeseri subsp. raeseri, Salvia officinalis, Origanum vulgare, Orchis mascula, Gentiana lutea, which are important for the Albanian flora due to their limited distribution within the country, are found also inside the Park territory.
