Forest Blowdown and Lake Acidification

Abstract

We examine the role of forest blowdown in lake acidification. Our approach combines geographic information systems Dobson, Rush, and Peplies Study Areas 08 Headwater Lakes CI

The role of tree uprooting in soil formation: A critical literature review

“…However, studies of extreme and large-scale disturbances are not interchangeable with studies of pit-mounds on the coarse scale. Even in such cases, pitmounds are still fine spatial scale objects, and their development is furthermore influenced by essential changes in the light, temperature, hydric and competition conditions in the stands (Mladenoff, 1987;Dobson et al, 1990;Kölling and Prietzel, 1995;Nachtergale et al, 2002;Schulte and Mladenoff, 2005). Some studies, e.g.…”

“…This increased nitrification resulted in an increase of acidification in the disturbed area. On the other hand, Dobson et al (1990) concluded that due to the changed hydric regime, a large-scale disturbance results in acidification only in streams in the lower part of the catchment. According to them, neutralization of acidic precipitation on disturbed plots does not occur because of lower contact with mineral soil horizons.…”

Biogeography in theAnnals

“…These concerns echo in recent Annals investigations that carefully integrate cultural and ecological processes: “the question is no longer if human intervention is appropriate, but what type of intervention is appropriate when tending nature” (Naughton‐Treves 2002, 502). While inquiries into the human dimensions of conservation have a long tradition in the Annals (e.g., Whitaker 1940), publications exploring the biogeographic implications of land cover change and land‐ownership patterns/policy have flourished in the most recent period (e.g., Dobson, Rush, and Peplies 1990; Walker and Solecki 1999; Feldman and Jonas 2000; Robbins 2001; Medley, Pobocik, and Okey 2003). Zimmerer (1994, 2000) points to the increasingly fruitful crossover between cultural ecology and “new ecology” (i.e., an emphasis on disturbance regimes, disequilibria, natural variability) and the promise of reinterpreting human relationships with nature, just as biological systems have been reinterpreted, with particular relevance to economic development.…”

The role of tree uprooting in Cambisol development

“…Bormann et al, 1995), or only extremely severe disturbances are assessed, in which the effect of soil disturbance on soil formation is masked by significant changes in the light, temperature, hydrology and competitive conditions within the forest stands (Dobson et al, 1990;Kölling and Prietzel, 1995;Nachtergale et al, 2002). The effects of longterm, chronic fine-scale soil disturbances by pit-mounds (Šamonil et al, 2009) on soil formation have not yet been studied on a coarse scale.…”
