Tree uprooting : review of types and patterns of soil disturbance
This paper reviews the formation and longevity of pit and mound microtopography formed by tree uprooting, and examines the importance of this process to mass wasting and soil genesis. This paper focuses on the physical environment, concentrating

Effects of slope angle on mass movement by tree uprooting
An examination of 189 well-delineated mounds and pits in sandy soils of northern lower Michigan, all presumably formed by tree uprooting, was used to determine the effects of slope angle on morphology and volume, and to assess the potential
importance of uprooting to mass movement. Data indicate that mound and pit volumes increase with increasing slope angle, suggesting that on gentle slopes more of the disturbed soil wastes off the mound, back into the new pit.

in natural systems is widespread. In the geomorphic subsystem its most obvious manifestation is the origin and disappearance of pit-and-mound microtopography resulting from tree uprooting. 82 pit-and-mound associations have been mapped on a test slope
and in younger trees, which have to adapt to the pre-existing pit-and-mound surface topography. The AA. offer a conceptual model that links biotic and abiotic factors and discuss implications of the widespread tree uprooting. They suggest that veneers of angular
clasts and occasional larger boulders are not necessarily residuals of washed Pleistocene solifluction mantles but may result from root plate degradation after uprooting.

The social organization of migration: an analysis of the uprooting and flight of Vietnamese refugees

This study examines and compares methods of dating pit/mound microtopography formed by tree uprooting, and provides C 14 evidence for the longevity of these landforms. The AA. use C 14 analysis of buried wood and charcoal in treethrow mounds

to the uprooting of trees by windthrow events, thereby causing variations in microtopography hereby referred to as pit–mound positions. A study site situated within the Tarbiat Modares University Experimental Forest Station located in the Mazandaran province
was chosen for this research, with 34 uprooted trees selected for detailed study. Statistical comparisons revealed that the highest soil microbial respiration and net N-mineralization occurred in pit bottoms. Mound tops showed the lowest levels of soil

The AA. used botanically identified and radiocarbon-dated charcoal macrofossils in mineral soils as a paleoecological tool to reconstruct past fire activity at the stand scale. Charcoal macrofossils buried in podzolic soils by tree uprooting were
