  Ireland's Peat Bogs   (Site not responding. Last check: 2007-10-10)
Blanket bogs are found wherever there is high rainfall, which is typically in western Ireland and also in mountainous areas.
They are called blanket bogs because of their appearance - from a distance they appear homogeneous and they hug the topography like a blanket.
However, the turf from blanket bogs is not as good quality as that from raised bogs, and thus blanket bogs have escaped the wholesale destruction inflicted on the latter.

On the western blanket bogs, in particular, the tawny grasses and bog-cotton of the turf shimmer in the Atlantic wind, lifting the eye to wide horizons and arching rainbows.
The raised bogs of the midlands and the blanket bogs of the west and the mountains have different structures and surfaces.
The raised bogs are made of the dead parts of sphagnum moss, while the blanket bog consists of the remains of grasses and sedges.

 Blanket Bog (University of Paisley: Biodiversity Reference)   (Site not responding. Last check: 2007-10-10)
Elsewhere, blanket bog seems often to be persisting in regions where rainfall is lower than when the bogs were first initiated, which has important implications for their potential recovery from damage and for their conservation.
Blanket bog is continuous over extensive areas, masking the underlying topography and also cutting the surface vegetation off from minerals in the underlying soil or bedrock.
In general, however, blanket bogs have a surface pH of around 3.8-4.0 and they are a hostile environment for all but a few species which are acid tolerant and able to conserve such minerals as they can acquire.

Overgrazing has led to erosion and habitat loss of 7% of the area of blanket bog in the last ten years and a further 7% is threatened by this activity.
Although 2% of the midland raised bogs have been afforested, large scale afforestation schemes have had the greatest impact in the blanket bog areas with planting on 27% of the area of blanket bogs.
Although the Wildlife Service indicated that 500,000ha of blanket bog remained with a potential conservation value (out of an original 774,990ha of blanket bog in Ireland), the completed NHA surveys have found that only 143,248ha is of European conservation importance indicating a loss of 82% of blanket bog habitat in Ireland.

Active blanket bog is a globally rare habitat for which the UK holds an international responsibility.
Blanket bog has its 'type' location in the UK and is recognised as a priority habitat for nature conservation action under European law (EC Habitats Directive) and a number of world-wide environmental conventions (Bern Convention, Ramsar Convention).
Blanket bog requires specific climatic conditions - persistently wet and cool in order to allow the growth of Sphagnum mosses, the driving force behind peat formation.

Blanket bog - these tend to be found in the wetter parts of Ireland and form directly onto the soil or bedrock.
Blanket bogs cover about 750,000 hectares of Ireland, much of it on uplands and mountain ranges, where rainfall exceeds 1,250 mm per year.
While both types of bog together make up 12% of the land area of Northern Ireland (about 170,000 hectares), there are only 25,000 hectares of lowland raised bog and much of this has been damaged by reclamation for agriculture and by turf extraction.

 Peatlands | Formation | Northern Ireland peatlands
The largest areas of raised bog are in the lowland corridor extending from the Lough Neagh Basin north along the Bann Valley in the east.
In the first half of the 20th century a large proportion of raised bogs were lost due to hand-cutting for fuel, and this has become increasingly mechanised during the second half of the century.
Blanket bogs have been used as a source of fuel and for rough grazing in Ireland for centuries, with organised reclamation of accessible areas of blanket bogs starting in the early 19th century.

A multinomial logit (MNL) model of the probability of bog occurrence was constructed in terms of relevant topographic characteristics.
The resulting model was then used to investigate the probabilistic boundary conditions of bog occurrence within the landscape.

The fields, enclosed by an integrated system of stone walls, have been preserved intact by a cover of blanket bog that is >4 m deep in places.
The pine roots in most cases are either on the surface of the mineral soil under the peat or at an intermediate level in the peat itself.
The age of the trees in the bog overlying Céide Fields is therefore of great significance for the dating of the fields, as the trees must be younger than the bog in which they are growing, which in turn must be younger than the field system beneath it.

ABSTRACT: The importance of topographic factors on the distribution of bog and heath in a Newfoundland blanket bog complex.
It is commonly assumed that the development of blanket bogs is governed more by climatic factors than by topography, but no quantitative studies have been undertaken.
The primary aim of this research was to quantitatively assess the extent and nature of the topographic influence of both the surface and the underlying substrate on the distribution of bog and heath communities within a blanket bog complex.
