WebIn peatlands, year-round water-logged conditions slow plant decomposition to such an extent that dead plants accumulate to form peat. This stores the carbon the plants absorbed from the atmosphere within peat soils, providing a net-cooling effect and helping to mitigate the climate crisis.. Peatland landscapes are varied: from temperate blanket mires with … WebPeat-forming conditions exist because the high and relatively stable water table in the acrotelm maintains waterlogged conditions and enables bog species to resist competition from other plant species which are not normally peat forming. Loss of peat-forming species means loss of peat forming function in the acrotelm Catotelm
No mass extinction for land plants at the Permian–Triassic
WebUltimately it results in loss of peat forming vegetation and consequent drying out of the bog surface. In sensitive locations the end-result of persistent high stocking levels is that the acrotelm is lost completely, the drier surface is colonised by non peat-forming species, patches of bare peat appear and erosion-risk increases as a consequence. Peat forms when plant material does not fully decay in acidic and anaerobic conditions. It is composed mainly of wetland vegetation: principally bog plants including mosses, sedges, and shrubs. As it accumulates, the peat holds water. This slowly creates wetter conditions that allow the area of wetland to … See more Peat , also referred to as turf (/tɜːrf/) (a word that also refers to soil with grass distinct from peat), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands See more In a widely cited article, Joosten and Clarke (2002) described peatlands or mires (which they claim are the same) as the most widespread of all wetland types in the world, representing 50 to 70% of global wetlands.

WebPeat forms when plant material does not fully decay in acidic and anaerobic conditions. It is composed mainly of wetland vegetation: principally bog plants including mosses, sedges, and shrubs. As it accumulates, the peat holds water. This slowly creates wetter conditions that allow the area of wetland to expand. WebTypical species include the important peat-forming species, such as bog-mosses Sphagnum spp. and cottongrasses Eriophorum spp., or purple moor-grass Molinia caerulea in certain circumstances, together with heather Calluna vulgaris and other ericaceous species.
