Abstract:
In the Căpăţânii Mountains the relief is dominated by rocks, which determined a saxicole vegetation, well developed in this region. Geologically, the mountainous region is made up of metamorphic, crystalline rocks, the Lotru series is framed in the unity of the Getic platform. The Lotru Crystalline is made up of the following types of rocks: mica-schists, crystalline schists, gneiss, mica and also amphibolites. Besides, there are jurassic limestones which are present in the following regions: Cheile Bistriţei, Costeştilor, Olteţului, Buila-Vânturariţa Massif and in the upper Luncavăţ basin (Sec Spring-Muchia Căşăriei-Pietrele Găuriciului Spring). According to the research carried out between 1997-2007, in the Căpăţânii Mountains, there were identified 3 vegetale associations belonging to POTENTILLETALIA CAULESCENTIS Br.-Bl. 1926 (Syn. ASPLENIETALIA RUTAE-MURARIAE Oberd. et. al. 1967) order: Asplenietum trichomanorutae murariae Tx. 1937 (Syn. Asplenietum rutae-murariae Schiwickerath 1944), Asplenio viridae-Cystopteridetum fragilis Oberd. (1936) 1949 (Syn. Cystopteridetum fragilis Oberd. 1938), Valeriano montanae-Corthusetum matthioli Boşcaiu et Täuber 1978. For each vegetal association the corology, ecology, aspect and floristic composition as well as their importance are taken into consideration.
