“…Further changes in soil morphology include the appearance of discontinuous miner- al horizons and buried organic horizons in mounds, increased solum thickness on mounds, and topsoil armouring due to bedrock mining. Similar changes have been reported from other regions (Pawluk and Dudas 1982;Beke and McKeague 1984;Veneman et al 1984;Phillips et al 2008Phillips et al , 2015Šamonil et al 2015). Partial inversion of soil horizons, reported by Schaetzl (1986) and Šamonil et al (2015), was evident when soil pH (Fig.…”

“…Generally, soils within pit-and-mound microsites undergo relative rejuvenation in comparison with undisturbed soil environments (Stephens 1956;Beke and McKeague 1984;Veneman et al 1984;Schaetzl 1990;Šamonil et al 2010a). This generalisation is consistent with the model of proisotropic pedoturbation, implying simplification of the soil profile within a regressive pathway of pedogenesis (Johnson et al 1987).…”

Abstract. The historical dimension of pit-and-mound topography has been studied at the Mt Rogowa Kopa locality, Stołowe Mountains, SW Poland. This site represents one of the best developed regional examples of hummocky forest floor relief due to widespread tree uprooting and subsequent degradation of root plates. Through map analysis and dendrochronology the disturbance history was traced to at least the 1930s and, most likely, a strong wind episode from 1933 was the reason for the forest calamity that resulted in the nearly total destruction of the original stand. However, the affected forest was a planted Norway spruce monoculture, introduced and managed until at least the beginning of the 20 th century, and not a natural forest. The windthrow niche was then used by beech, whose individuals preferentially chose mounds to grow, conserving the hummocky microtopography. Changes in soil evolutionary pathways brought about by wind-driven disturbance include both haploidisation (rejuvenation) and horizonation (differentiation). Evidence of soil rejuvenation includes a decrease in organic carbon content and an increase in pH in the upper parts of soils developed on mounds relative to the pH of undisturbed references soils. Soil texture was relatively homogenised in pits and mounds. Dating of the pit-and-mound microrelief by means of soil properties (organic carbon content, iron forms) was only partly successful. Although the young age of pits and mounds is evident, the actual age inferred from soil properties was underestimated by a few tens of years. Evaluation of factors potentially controlling the propensity to widespread treethrow suggests that the type of forest is a far more important variable than local abiotic factors of bedrock geology, regolith characteristics, and slope inclination.

“…The most important feature here is the hummock and hollow microtopography created by the overturn of trees. The influence of tree overturn by windthrow on soils is well known (Lyford and MacLean, 1966;Brewer and Merritt, 1978;Beke and McKeague, 1984) but its effect on soil development is not widely understood in New Zealand (Ives et al, 1972). The disturbance of soil is a common occurrence in New Zealand beech forests (Laffan, 1979) because the beech trees have a very shallow rooting system, and when they fall over, soil to a depth of about 40 cm over an area of about 2-6 sq m is wrenched free by the tree roots.…”

“…Windthrow is considered to contribute significantly to the shortrange variation commonly observed in forest soils (Lutz, 1940;Lyford and MacLean, 1966;Laffan, 1979;Beke and McKeague, 1984;Campbell and Mew, 1986;Norton, 1989), Distribution patterns of both canopy trees and forest understorey species have also been related to pit and mound microtopography (Lyford and MacLean, 1966;Putz, 1983;Beatty, 1984).…”

The effects of tree windthrow on soil properties and vegetation were studied in an area of rimu (Dacrydium cupressinum) forest on a dissected glacial outwash surface in Saltwater State Forest, South Westland, New Zealand. Tree windthrow and the resulting formation of surface pits and mounds caused a redirection of pedogenesis, particularly on relatively better-drained low ridges; there, the normal development of a gleyed yellow-brown earth profile was altered towards organic soils in the pits and podzolised yellow-brown earths on the windthrow mounds. In poorly drained backswamps, organic soils also formed in the pits, while gleying processes predominated in both the windthrow mound soil and the adjacent unmodified soil. The sequence of vegetation development was different on windthrow pits compared with mounds. Mounds were rapidly colonised by ground-cover plants, especially ferns and tree ferns. These were subsequently replaced by broad leaved trees, particularly kamahi (Weinmannia racemosa). Pits usually pond with water. Plant litter then fills the pits within 30 years. The pit sites are subsequently colonised by vascular plants, but the succession involved is not clear. In this high rainfall environment, pits and mounds become unrecognisable on the land surface within about 100 years. Windthrow contributes to the currently observed soil pattern in these forests.
