Blanket bogs of ireland factsheetirish peatland conservation council electricity voltage used in usa


Atlantic blanket bogs cover the landscape of the west coast from sea level to an altitude of 200m. Here, rainfall is 1,200mm per year and the acid peat substrate ranges from 2 to 7m deep. Atlantic blanket bog vegetation has a characteristic grassy appearance due to the occurrence of purple moor grass ( Molinia caerulea) and black bog rush ( Schoenus nigricans). Patterned surfaces of pools, flat and sloped areas, flushes and swallow holes are important features of blanket bogs.

Mountain blanket bogs occur on relatively flat terrain in the mountain ranges above 200m altitude. Here rainfall is high and evaporation is low. harry mileaf electricity 1 7 pdf Mountain blanket bogs are rain fed and their peat is acidic. The vegetation is characterised by the presence of ericoid shrubs and in particular ling heather ( Calluna vulgaris), crowberry (Empetrum nigrum) and bilberry ( Vaccinium myrtillus). Natural drains, lakes and flushes are features of mountain blanket bogs. Formation of Blanket Bogs

Blanket bog formation in the mountains and lowlands of the west of Ireland started at the end of the last glaciation, 10,000 years ago. gasco abu dhabi careers Initially peat formation was confined to shallow lakes and wet hollows. Over time an infilling sequence from open water to fen and acid peat occurred to form the blanket bog habitat we find today. Later, acid peat spread out to form a blanket covering huge areas of poorly drained land. While some spread may have taken place as early as 7,000 years ago, many areas were not engulfed until 4,000 years ago when the climate became wetter. Heavy rainfall caused minerals such as iron to be washed out or leached from the surface layers of the soil, a process know as paludifacation. These were deposited lower down where they formed an impermeable layer known as an iron pan. Water cannot move down through such a layer and the soil surface became waterlogged as a result. Under these conditions the accumulation and spread of peat was made possible. hp gas online booking phone number Distribution of Blanket Bogs in Ireland

Blanket bog occurs on flat or sloping land with poor surface drainage, in cool, wet, oceanic climates. Moore et al. (1984) describe blanket bogs as a “complex unity combining flushed and ombrotrophic peatland types which occupy a variety of geomorphological positions and which become inextricably linked in an interdependent, but floristically and hydrologically diverse, series”. If the climate is sufficiently cool and wet, basins, plateaux and gentle slopes come to be swamped by peat, formed from acid vegetation. Peatland formed by the terrestrialisation of basins or the paludification of plateau and gentle slopes at different places in the same landscape, eventually coalesce to form a blanket bog complex. Therefore blanket bogs are complexes which combine several congruent and hydrologically inter-related peatland sites into a continuous peatland system. Within the complex, the underlying peat varies considerably in depth and humification, according especially to the angle of the slope and the degree of waterlogging. electricity equations physics Morphologically the blanket bog peat body is diplotelmic in profile as in raised bogs. It is divided into two distinctive hydrological layers, the acrotelm and the catotelm. Importance of Blanket Bogs

Under the EU Habitats Directive the National Parks and Wildlife Service (NPWS) are obliged to complete a report every 7 years on the condition of designated habitats. gas 93 octane The assessments carried out in 2006 and 2013 found that no peatland type of priority importance in Ireland is in good conservation status. Blanket bogs were given a BAD assessment in these reports due to the loss of their area, structure and function. The drivers of the loss of blanket bogs include reclamation, peat extraction, afforestation, over grazing, drainage, burning, erosion and landslides . Extent and Utilisation of Blanket Bog

Originally 908,117ha of blanket bog covered the island of Ireland. Although blanket bogs originally covered more than 774,367ha of the land surface in the Republic of Ireland (Hammond Peatland Map 1979), hand cutting over 400 years, the introduction of large-scale, mechanised turf extraction, afforestation programmes, intensification of agriculture and land reclamation have seriously depleted the area of blanket bog suitable for conservation. IPCC monitors the status of the resource on an on going basis. Our assessment of 2009 was published in Ireland’s Peatland Conservation Action Plan 2020. z gas el salvador numero de telefono This found that only 28% (216,599ha) of the blanket peatland resource remains in a relatively intact condition in the Republic of Ireland. Traditional cutting of the bogs for turbary is having a serious impact on blanket bogs. 36% of the blanket bogs have been cutaway by this process. Peat is still being cut privately. Grazing pressure on blanket bogs although particularly severe during the last century mainly by cattle did not result in degradation of this habitat. Sheep replaced cattle as the principal grazing animal with the introduction of EU farming subsidies in the 1980’s and have caused severe erosion and complete loss of sites. Overgrazing has led to erosion and habitat loss of 7% of the area of blanket bog since 1980 and in 2000 a further 7% was deemed threatened by this activity. Large-scale afforestation schemes have had a huge impact on blanket bogs with planting on 28% of the original area within the Republic of Ireland. electricity questions grade 6 EU and Government incentives introduced since the mid 1990’s have resulted in an interest in wind energy developments which seriously degrade the integrity of mountain blanket bogs. Another cause of blanket bog degradation is the colonisation of the habitat by invasive alien species such as Rhododendron ponticum and Pinus contorta. Blanket Bog Campaign 2016/2017

In 2016 IPCC mounted a two year campaign to shift the national focus to blanket bogs and bridge the significant policy gap that exist in relation to their protection. The campaign aims to engage in lobbying and advocacy to ensure that blanket bogs are highlighted as a national issue. gas yoga The first step was to set up an online survey to assess what damage and threats currently face blanket bog. This involved a step into citizen science as we asked users to fill in our survey and tell us of their experience while visiting such sites. This allowed us to analyse which issues were causing the most pressure to this precious habitat and allowed us to emphas ise these in meetings with key Government officials. Take for example Slieve Tooey/Tormore Island/Loughros Beg Bay SAC in Co. Donegal which was used as a case study to highlight the variety of uses currently found on blanket bog. The survey provided evidence of a wide range of threats including the use of quad bikes for herding sheep on sensitive bogland habitat, extensive turf cutting and footing using machinery, drainage, peat erosion, grazing by sheep, installation of telecommunication towers, bee keeping and walking.
