Record of the landslide processes in annual growth of Silver fir (Abies alba Mill.) roots : example from the Carpathian Foothills

Celem badań było rozpoznanie czasowej i przestrzennej aktywności procesów osuwiskowych z zastosowaniem analizy zmian anatomicznych w korzeniach jodły pospolitej (Abies alba Mill). Ponadto określono zależności między warunkami opadowymi a odnotowanym procesem osuwania. Badania wykonano na niewielkim osuwisku o powierzchni 0,14 ha zlokalizowanym na terenie Pogórza Wiśnickiego, w obrębie płaszczowiny podśląskiej zbudowanej z fliszu karpackiego. Analizie poddano pionowo rosnące korzenie odsłonięte na krawędzi skarpy osuwiskowej. Pomiary anatomiczne drewna były wykonywane w programie WinCELL Pro (Regent). Stwierdzono przydatność w analizach procesów osuwiskowych zastosowania różnych wskaźników zmian anatomicznych. Wykazano zależność aktywności osuwiska z różnymi typami opadów w latach 1970, 1974, 1989, 1997 i 2010.The aim of the research was to detect the landslide activity by means of analysis of wood anatomy of exposed silver fir roots. Additionally we analysed relation between precipitation and landslide activity. The research was carried out on a small landslide (0.14 ha) located in the Wiślickie Foothills within the Podślaska Nappe built of flysch rocks. Vertical roots exposed on the edge of landslide niche were taken under consideration. Wood anatomy changes were analyzed in WinCELL Pro software (Regent). It was concluded that spatial activity of landslides require analysis of different wood anatomy indicators. The relation between the landslide activity and different type of precipitation was revealed for 1970, 1974, 1989, 1997 and 2010

Polish geomorphological research in the Eastern Carpathians and the significance of Bieszczady National Park in the protection of inanimate nature

The paper describes Polish geomorphological research in the Eastern Carpathians mainly prior to World War II. Special attention is paid to the work of geomorphologists in the area of glacial relief recognition. The state of geomorphological research in the Bieszczady Mts was presented to a large extent in Volume 19 of the Roczniki Bieszczadzkie. Finally, the paper discusses the tradition of environmental protection in the Eastern Carpathians as well as significance of the Bieszczady National Park in the protection of inanimate nature

The state of the art of the studies on the Bieszczady Mts. geomorphology

The paper concerns the state of the art in research on the relief and geomorphic processes in the High and Low Bieszczady Mountains. On the basis of literature evaluation authors concluded that subsequent, detailed fieldwork is required. Furthermore additional research could supplement former opinion about development of slope and valley systems within area under considerations
