oscillating peat surface levels in a restiad peatland

Tropical climates reached their northernmost expansion during the early Paleogene greenhouse phase supporting a paratropical biota as far north as the southern shore of the ancient North Sea There relative sea-level fluctuations led to the formation of transgressive-regressive sequences exposed in open-cast lignite mines in the area of Helmstedt (Lower Saxony Germany) which record

Peat Depth Survey Guidance

of the total peat and carbon resource Peat Depth Survey Guidance Page 2 Survey Method You will need 1 SNH may be able to loan a peat probe upon request but they are also available on the internet as Peat Probes The length of the rods should be sufficient to measure the full depth of the peat Bamboo canes are unsuitable as they will snap and could cause injury 2 A handheld GPS device

Hence fire can easily burn the peatland area starting on the peat surface Changes in peatland cover from swamp forest to agriculture plantation or settlement may cause decreasing water level in the peat As a consequence the decreasing water level may increase the risk of forest and land fires due to dry peat condition Susilo et al 2013) and may decrease peat moisture content as an

Peat and peatland statistics Peatland vegetation In boreal and temperate regions Sphagnum mosses are one of the primary components of peatland vegetation They play a very important role as they give peat its valued horticultural properties and form a virtually unbroken cover where other plants may establish and grow Plants typical of bogs Because bogs are nutrient poor wet and acidic

Peatland restoration has many other benefits including providing an internationally important habitat improving water quality and reducing flood risk To restore a peatland you need to re-establish the environmental conditions required for peat to form How soil information can help you restore peatland In general knowing what soils you have will give an indication of how suitable your

The Global Distribution of Peat

that the global distribution of peat is very uneven The peatland area in North America is the largest accounting for 43 54% of the total global peatland area followed by Asia (28 08%) and Europe (24 02%) The total global peatland area is estimated to be about 4 x 106 km2 The peat reserve in Asia is the highest next is Europe then North America and Oceania is the lowest The total global

Peat forests and the ecosystem services they provide are being transformed at a critical rate - between 2007 and 2015 the rate of loss was 2 6% per year in Sumatra and Kalimantan (Miettinen et al 2016) Growing demand for arable land in particular for palm oil production lack of suitable unused uplands and the attractiveness of peatlands' availability and flat topography (as opposed to

Oscillating peat surface levels in a restiad peatland New Zealand - magnitude and spatiotemporal variability By C Fritz D I Campbell and L A Schipper Abstract Contains fulltext 181968 pdf (publisher's version ) (Closed access Topics Aquatic Ecology

To investigate the spatiotemporal variability of PSO surface elevation and the water level above sea level (AWL) were measured monthly (23 sites) over one year in a warm-temperate restiad peatland New Zealand At one site peat surface elevation was measured indirectly by monitoring AWL and RWL continuously with pressure transducers Annual PSO (the difference between maximum and minimum

PAGES' Carbon in Peat on EArth through Time working group will hold a workshop titled Short-Term Peatland Patterns Processes and Sensitivity to Rapid Climate Change from 10-13 May 2018 in College Station TX USA Venue Texas AM University College Station TX USA Logistics This is a meeting for 15-20 invited participants

Carbon emissions from drained and degraded peatland in Indonesia and emission factors for as the peatland surface is found to readjust to the post-drainage water table as a result of oxidation processes be they biological or fire-induced In terms of carbon accounting this can greatly simplify methodologies over longer periods removing the need to account for individual fires but only

Effects of water table position and plant functional group

Our objective was to assess the impacts of water table position and plant functional type on peat structure plant community composition and aboveground plant production We initiated a full factorial experiment with 2 water table (WT) treatments (high and low) and 3 plant functional groups (PFG sedge Ericaceae sedge and Ericaceae- unmanipulated) in twenty-four 1 m3 intact peatland mesocosms

Peat is the surface organic layer of a soil that consists of partially decomposed organic matter derived mostly from plant material which has accumulated under conditions of waterlogging oxygen deficiency high acidity and nutrient deficiency In temperate boreal and sub-arctic regions where low temperatures (below freezing for long periods during the winter) reduce the rate of

This paper derives the distribution of peatland in Europe as the extent of peat and peat-topped soils indicated by soil databases The data sources were the 1 1 000 000 European Soil Database (v1 0) and a data set of organic carbon content (%) for the topsoils of Europe at 1km x 1km resolution that was recently published in map form The strong influences of vegetation and land use on soil

Definitions of peatland or peat deposits change according to the focus of research and potential uses C A Weber (a German peat scientist) considered that peatland must have at least a 20 cm peat layer after drainage E Granlund (from Sweden) thought that under natural conditions peatland must have a 40 cm thick layer of peat In addition to

[11] Peatland surface position was simulated using a simple Kelvin‐Voigt model as a first approximation to viscoelastic deformation [Barden 1968 Middleton and Wilcock 1994] In this model 10 peat blocks are connected in series by elastic (e g spring) and viscous (e g dashpot) elements (Figure 3) to the underlying mineral sediments

Peat compresses when the water table recedes as the peat matrix is no longer supported by pore water pressure which increases effective stress in the OSCILLATING PEAT SURFACE LEVELS IN A RESTIAD PEATLAND Figure 1 De nition diagram showing how differences in water table (WT) positions in a peatland depend on changes of the surface elevation (SE) where a benchmark (e g
