“…Mean slope angles fall within the range of 20-40°, and locally thin regolith-covered slopes are as steep as 60°. Except for footslope settings, slopes in the area carry a rather shallow regolith cover, less than 2 m thick (Migoń et al, 2010;Kacprzak et al, 2013 Within the 30-year period of observations, the monthly rainfall in summer (MaySeptember) exceeded 100 mm in 36 instances, occasionally rising above 250 mm. An absolute monthly maximum was recorded in July 1997 (344 mm).…”

“…The whole landslide assemblage is crowned by a distinctive head scarp more than 40 m high and occupies the altitude belt 880-680 m a.s.l. A few separate types of displacement have been distinguished within the complex through landform analysis, and different ages have been proposed on the basis of evident differences in soil development and characteristics (Kacprzak et al, 2013).…”

Abstract:We found ubiquitous evidence of ongoing slope instability by analysing the variability of tree-ring eccentricity index in trees growing on three apparently relict landslide slopes in the Sudetes (Poland, Central Europe). Slow movement of these landslide bodies occurs in the present-day conditions and is recorded almost every year, although with variable intensity. Correlation of dendrochronological record with the rainfall record from a nearby station in Mieroszów for the 1977-2007 period is very poor for two deep-seated rotational slides at Mt Suchawa and Mt Turzyna but considerably better for a shallow flowslide at Mt Garbatka. While this may reflect higher permeability of heavily jointed rocks involved in deep-seated sliding this could be linked with imperfections in the rainfall record. Dendrochronology proved capable of detecting minor displacements within landslides which otherwise show no geomorphic evidence of recent activity. Therefore, claims for the entirely relict nature of the landslides are not substantiated.

In this work, direct and indirect geomorphic consequences of wind-related tree uprooting are examined, using an extensive dataset from the mountain range of the Sudetes, Poland. The role of local conditions in influencing the geomorphic efficacy of tree uprooting is examined, as well as issues of upscaling individual observations from experimental sites. This problem is approached at a range of spatial and observational scales, from monitoring of root plate degradation over time through to examination of wind effects at a slope scale and region-wide analysis. In our study area the mean root plate volume is between 0.4 and 4.2 m 3 for spruce and 2.4 m 3 for beech, and their degradation may last tens of years. The density of relict pit-and-mound microtopography varies from 2.7 up to 40 pairs per hectare and the maximum coverage of terrain is 4.7%. The volume of treethrow mounds varies from 0.5 to 3.1 m 3 and mounds seem to outlive the pits formed in the same episode of disturbance. However, in specific lithological and topographic conditions, pit-and-mound topography does not form. The maximum biogenic transport attributable to a single windstorm event is c. 80 m 3 ha À1 , while soil turnover times are calculated in the order of 1000-10 000 years. Rock fragment 'mining' is an important biogeomorphic process, both in terms of impact on hillslope surfaces and on soil properties. Gravel armours and small-scale stepped topography may form instead of typical pit-mound associations in specific circumstances. Managed forests appear more prone to wind damage and associated geomorphic consequences. In the Sudetes Mountains, the variable role of tree uprooting in local and regional hillslope denudation is governed by forest stand structure, topography and regolith properties, with the former significantly influenced by human activity.
