A syntaxonomic and synecological survey is presented on the flora and vegetation of high mountain limestone-screes of the South Anatolian Western and Central Taurus mountains (Bati and arta Toroslar). The endemic-rich subalpine to subnival screes (2000-3700 m) are phytosociologically characterized by two particular orders. The screes of the Bati Toroslar belong to the Lamietalia cymbalariifolii, those of the arta Toroslar to the Heldreichietalia. Both can be combined into the Heldreichietea class. The Lamietalia cymbalariifolii interpose between the Heldreichietalia and the Drypidetea spinosae of the Balkans and Northwest Anatolia. The Scrophularion depauperatae (3 associations) is the scree alliance of the Bati Toroslar. The Scrophularion myriophyllae (2 associations) comprises the limestone-screes of the western arta Toroslar. Both units represent monotypic suborders (Bati Toroslar: Lamienalia cymbalariifolii; western arta Toroslar: L. glandulosidentis). In the eastern part of the Central Taurus two altitudinally arranged alliances form the Lamienalia eriocephali suborder. The Scrophularion rimarum (4 associations) is centred in the subalpine belt, inhabiting relatively coarse moving screes. The Jurinellion moschus (5 associations) occupies cryoturbated, finer structured and partly stabilized talus slopes of the upper alpine and subnival belt. For all syntaxa, chorotype spectra and chorological peculiarities are discussed. Based on growth and life forms, a new life strategy concept, designed to taxa of mobile screes, is presented. Analysis of dispersal and reproductive biology (dispersal types and range, clonal reproductive effort), regenerative effort, space occupation strategies, and phytosociological data form part of this approach. Determining the mean percentage cover, the base of the weighted analysis, allows the ecological significance of 5 different strategies within the scree communities to be demonstrated.
