Summary: Lichenometric research used for geomorphological forms and processes dating have been carried out by many geologists and geomorphologists concerning the areas of the Alps, Sweden, Norway, Finland, Arctic regions (Beschel 1957; Burrows 1971; Denton and Karlén 1973; Birkenmajer 1979a, b; André 1986; Hietaranta and Liira 1995; Kotarba 2000, 2001) and other parts of the world as well as in the Tatra Mts (Kotarba 1988, 1989, 1992, 1997) and the Beskid Śląski Mts (Bajgier 1992) in Poland. Lichenometry is based on the statement that thalluses of lichens with the largest diameter point out the age of the surface they overgrow as the first and with the greatest speed. Common species of Rhizocarpon which develop slowly are commonly used for rocky surface dating. Development of lichens takes place with different speed in different climatic zones and belts so for each of the studied area the curve of lichen thallus development should be drawn and estimated the coefficient of thallus development - so called lichenometric model. In Poland (Fig. 2) it was estimated for very cool belt (38.1 mm/100 yrs), moderate cold (32.5 mm/100 yrs) in the Tatra Mts (Kotarba 1988, 1989) and for cool belt (42.8 mm/100 yrs) and very cool (39.6 mm/100 yrs) in the Beskidy Mts (Bajgier 1992; Bajgier-Kowalska 2001). The research carried out by the author aims at presenting the succession of landslide movements in the upper Holocene.
The Beskid Żywiecki is situated within the magurska overthrust. It does not make a homogenous mountain range but consists of several montane groups. The southernmost is the range of Wielka Racza and the main range runs evenly with the parallel of latitude from Wielka Racza (1,236 m) to Jaworzyna (1,176 m), Wielka Rycerzowa (1,226 m) to Oszast (1,152 m). More to the north and to the east there is the Pilsko range which is radially dissected by deep valleys with large landslides in the river headwaters. The highest elevations are Pilsko (1,557 m), Lipowska (1,324 m), Romanka (1,366 m) and Boraczy Wierch (1,144 m). Except for Pilsko all hills are within cool climatic belt. They are modelled by rocky landslides (Ziętara 1968) niches of which are developed in the magura sandstones and middle and lower parts of the landslides are developed in the submagur and inoceramic beds. The highest montane group in the Beskid Żywiecki is Babia Góra (1,725 m) more to the north-east of Pilsko. It consists of great syncline filled with thick-bedded magura sandstone under which there are hieroglyphic layers with slate predominance.
On the slopes of Romanka, Rysianka, Lipowska and Boraczy Wierch, in the cool climatic belt (above 980 m), on rocky walls of landslide niches and on slided blocks within colluvial covers there were measured lichens Rhizocarpon thalluses (Figs. 3, 4, 5). Analysis of their size points out that the greatest, regular thalluses began to be formed on fresh rocky walls ca 1610, 1705-1720, 1800, 1934, 1958-1960. Those years make the phases of landslide succession and they point out for wet episodes in the upper Holocene.
On the northern slope of Babia Góra within the back wall of huge rocky fall-out which was formed at the end of the Pleistocene (Alexandrowicz 1978), there are huge landslides (Ziętara and Ziętara 1958, Ziętara 1962) with very well preserved rocky walls in niches or on side edges on which there are Rhizocarpon lichens (Figs. 7, 8). Lichenometric dating on 24 localities (Fig. 6) within very cool belt (1,390-1,650 m) point out for co-existence of different generations of landslide forms both old and young, presently active. Slope relief was modelled under the repeated mass movements which occurred in different parts of the slope in different time (Tab. 2). Times of active gravitational mass movements occurred mainly during the end of the Little Ice Age (1560, 1609, 1748, 1796-1798, 1829-1833, 1844-1848, 1861-1869, 1881-1884). They occurred also during wet years with great floods (1910-1916, 1958-1960). So, such numerous, clear landslide forms preserved in relief of that slope are the result of different age stages of mass movements development leading to rejuvenation of landslide surface morphology.
