Paludification and management of forested peatlands in Canada: a literature review

Abstract: The Clay Belt region of Quebec and Ontario supports a large forest resource and an important forest industry. In this region, the majority of the harvested volume allotted to forest companies is in forested peatlands and boreal forests prone to paludification. Paludification is the accumulation of organic matter over time, and is generally believed to be caused by increasing soil moisture and Sphagnum colonization. Paludification is influenced by external and internal factors; it reduces soil temperature, deco… Show more

“…Net primary productivity (NPP) decreases as the forest transitions from deciduous to needleleaf forest since nutrients become less available as organic matter builds up in the soil and a change to more recalcitrant species occurs (Berg, 2000). Development of black spruce/feathermoss systems constrains decomposition thermally, and this limits nutrient availability for net primary productivity (Lavoie et al, 2005;Wickland and Neff, 2008). Consequently, CO 2 uptake is low under slow-growing black spruce forests, but respiration (and thus CO 2 release) also slow as organic carbon accumulates in the soil.…”

“…Mean total annual precipitation was 906 and 890 mm, respectively [44]. The poor drainage conditions induced by the presence of an impermeable clay substrate, flat topography, historical low fire activity, and cold climate facilitated the accumulation of thick layers of organic soil, a process often described as paludification [45,46]. In parts of the region, peat mosses accumulate on initially mesic soils, independently of topography or drainage, and are related to forest succession [34].…”

“…Conversely, duff loads increased gradually in coniferous choronosequences, since the lower decomposition rates associated with the paludification process favor organic layer accumulation [34,45,46]. The most interesting fact is that despite a tree and DWD load loss with TSF in coniferous forests, total fuel loads increased with TSF.…”

“…Sin embargo, se ha demostrado que en bosques turbosos de zonas boreales, en ausencia de alteraciones catastróficas, procesos de paludificación (acumulación de materia orgánica) llevan a estos sitios a perder productividad a medida que pasa el tiempo y no ha mejorarla Lavoie et al 2005;Simard et al 2007). En este sentido la acumulación de turba está controlada mayoritariamente por factores autogénicos (sucesión) y la reducción por factores alogénicos como los incendios (Simard et al 2007), lo cual se contradice con la idea inicial de sucesión natural para los bosques dominados por P. uviferum.…”
