Sixty-four algal species were found; Cyanoprokaryota (42.2% of species composition) and Chlorophyta (35.9%) are prevailed among them. Thirty-eight species formed growth on limestone outcrops and quartz crystals underlying on soil. Desmococcus olivaceus (Pers. ex Ach.) J.R. Laundon, Trentepohlia sp., Gloeocapsa aeruginosa Kütz. and Dilabifilum sp. dominated on limestone rocks; Nostoc cf. linckia (Roth) Bornet et Flahault and Tolypothrix sp. are formed growth on quartz. Fourty-five species were found in soil crusts developed on shelly sand and clay slopes. Crusts are formed by Microcoleus vaginatus Gomont ex Gomont, Hassallia cf. byssoidea Hassal ex Bornet et Flahault, Nostoc commune Vaucher ex Bornet et Flahault and Nostoc cf. edaphicum Kondrat., rarely by Klebsormidium crenulatum (Kütz.) Lokhorst., in saline areas —Coleofasciculus chtonoplastes (Thur. ex Gomont) Siegesmund et al. Species composition and dominating complex are characterized these habitats as typical for maritime territory with arid climate.
