paludification

(ecology)
Bog expansion resulting from the gradual rising of the water table as accumulation of peat impedes water drainage.

We define the extent and thickness of peat and Quaternary sediments with geomorphology of the sub-peat surface to understand what were/are the natural preconditions for onset of paludification, further development, present situation and future preservation of the Selisoo mire.
Eipurs Bog has formed due to the paludification of the sandy ground as a result of rising groundwater level and wet conditions during the small depression after the Ice Age.
In general, the distribution of plant macrofossils in cores BF-12, 9, 7, and 5 reflects a gradual hydrological change from a poorly drained area to the formation of a peatland and paludification as the water level decreased.
Paludification is the process of organic matter accumulation in saturated soils due to depressed decomposition rates under anoxic conditions and is responsible for the formation of organic horizons on ditch soil surfaces.
Firstly, due to rise in ground-water table, paludification, and overgrowing of relict lakes and lagoons isolated during the regression phases of the Baltic Sea.
Three possible explanations for this transition are proposed: 1) aquatic conditions could have prevailed from the beginning, and the white spruce and tamarack remains were deposited in the water from the surrounding upland, 2) the cone layer could represent a terrestrial forest that existed on overburden of a buried ice-mass that later melted and created a water-filled depression with associated aquatic flora, and 3) the cone layer could represent a terrestrial environment that was later subject to paludification from increases in meltwater from the retreating glacial ice to the north or from beaver activity.
Because decomposition proceeds more slowly in the more acidic environment of the bog-centre than at its margins, the accumulation of decay-resistant sphagnum eventually raises the surface to produce a domed or raised bog with a convex profile in a process known as paludification.
There are two main groups of wetlands: mineral wetlands, commonly situated in high-energy settings; and peatlands, situated in low-energy settings that undergo either terrestrialization or paludification during the course of their development.
marked by a thin transition zone, was likely a result of paludification or lake filling.
For example, regional water-level changes cause paludification (Miller and Futyma, 1986) and affect lake morphometry, limnology and, consequently, ontogeny.
During this period periglaciation, podzolization, and paludification were ubiquitously initiated in the Scandes Mountains (cf.
These soils are divided into two varieties according to the degree of paludification, which is reflected in the soil profile by the degree of soil mineral part gleyification and by the extent of peat forming in the epipedon.
