Stoki sudeckie piętra leśnego w holocenie (Forest belt hillslopes of the Sudetes in the Holocene)
Journal Title: Acta Geographica Lodziensia - Year 2017, Vol 106, Issue
Abstract
Forested hillslopes in the Sudetes have been long considered as a stable geomorphic environment, typified by landforms and cover deposits inherited from the periglacial environment. The results of recent research show that such an extreme view is no longer tenable. Slopes under forest are continuously shaped by coexisting denudational (mass movements, surface wash, throughflow, soil creep) and biogeomorphological processes (treethrow and detachment of root plates). Some processes operate on a permanent basis, others are episodic and are triggered by extreme weather events such as heavy rains and strong wind. They also differ in terms of the spatial scale of occurrence. Creep, throughflow and treethrow affect large parts of hillslopes whereas particle fall and debris flow have highly localized nature. New landforms due to Holocene processes are mainly pit-and-mound associations, resultant from tree fall and decay of root plates. New generations of cover deposits have come into being, whereas the structure of Pleistocene deposits is subject to alteration due to bio- and pedoturbations. An important role is played by human interference, with linear erosion on bare surfaces of roads and logging tracks being particularly significant.
