Slieve Gallion
Slieve Gallion () is a mountain in County Londonderry, Northern Ireland. It is the easternmost of the Sperrin Mountains. It reaches a height of and dominates the western shore of Lough Neagh. Its prominent northeastern summit has a transmitter station with a small road leading to it, and stands at a height of . By road, Slieve Gallion is from Moneymore, from Cookstown, and from Magherafelt. The mountain is part of the parishes of Desertmartin, Lissan and Ballinascreen. Nature Slieve Gallion is a volcanic plug. The mountain is formed from volcanic-derived igneous rock, and also granite on the southern slopes. It is steep, and has a flat top. There is a telecommunications mast on the northeastern summit. To the west, the landscape consists of blanket bog and coniferous forest; most of the trees in the Slieve Gallion area are Sitka spruce. There are also lodgepole pine trees, as well as oak towards the south of the area. Animal species living in the area include the Ir ...

Marilyn (hill)
This is a list of Marilyn hills and mountains in the United Kingdom, Isle of Man and Ireland by height. Marilyns are defined as peaks with a prominence of or more, regardless of height or any other merit (e.g. topographic isolation, as used in Munros). Thus, Marilyns can be mountains, with a height above , or relatively small hills. there were 2,011 recorded Marilyns. Definition The Marilyn classification was created by Alan Dawson in his 1992 book ''The Relative Hills of Britain''. The name Marilyn was coined by Dawson as a punning contrast to the '' Munro'' classification of Scottish mountains above , but which has no explicit prominence threshold, being homophonous with (Marilyn) '' Monroe''. The list of Marilyns was extended to Ireland by Clem Clements. Marilyn was the first of several subsequent British Isles classifications that rely solely on prominence, including the P600s, the HuMPs, and the TuMPs. Topographic prominence is a more difficult to estimate than ...

Igneous
Igneous rock (derived from the Latin word ''ignis'' meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms, orogens, basins, large igneous provinces, extended crust and oceanic crust. Geological significance Igneous and metamorphic rocks make up 90–95% of the ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global ...

Otter
Otters are carnivorous mammals in the subfamily Lutrinae. The 13 extant otter species are all semiaquatic, aquatic, or marine, with diets based on fish and invertebrates. Lutrinae is a branch of the Mustelidae family, which also includes weasels, badgers, mink, and wolverines, among other animals. Etymology The word ''otter'' derives from the Old English word or . This, and cognate words in other Indo-European languages, ultimately stem from the Proto-Indo-European language root , which also gave rise to the English word "water". Terminology An otter's den is called a holt or couch. Male otters are called dogs or boars, females are called bitches or sows, and their offspring are called pups or cubs. The collective nouns for otters are bevy, family, lodge, romp (being descriptive of their often playful nature) or, when in water, raft. The feces of otters are typically identified by their distinctive aroma, the smell of which has been described as ranging from fres ...

Red Grouse
The red grouse (''Lagopus lagopus scotica'') is a medium-sized bird of the grouse family which is found in heather moorland in Great Britain and Ireland. It is usually classified as a subspecies of the willow ptarmigan but is sometimes considered to be a separate species, ''Lagopus scoticus''. It is also known as the moorcock, moorfowl or moorbird. ''Lagopus'' is derived from Ancient Greek (), meaning " hare", + (), "foot", in reference to the feathered feet and toes typical of this cold-adapted genus, and ''scoticus'' is "of Scotland". The red grouse is the logo of The Famous Grouse whisky and an animated bird is a character in a series of its adverts. The red grouse is also the emblem of the journal '' British Birds''. Description The red grouse is differentiated from the willow ptarmigan and rock ptarmigan by its plumage being reddish brown, and not having a white winter plumage. The tail is black and the legs are white. There are white stripes on the underwing and ...

Curlew
The curlews () are a group of nine species of birds in the genus ''Numenius'', characterised by their long, slender, downcurved bills and mottled brown plumage. The English name is imitative of the Eurasian curlew's call, but may have been influenced by the Old French ''corliu'', "messenger", from ''courir '', "to run". It was first recorded in 1377 in Langland's Piers Plowman "''Fissch to lyue in þe flode..Þe corlue by kynde of þe eyre''". In Europe "curlew" usually refers to one species, the Eurasian curlew (''Numenius arquata''). Description They are one of the most ancient lineages of scolopacid waders, together with the godwits which look similar but have straight bills. Curlews feed on mud or very soft ground, searching for worms and other invertebrates with their long bills. They will also take crabs and similar items. Distribution Curlews enjoy a worldwide distribution. Most species show strong migratory habits and consequently one or more species can be ...

Mountain Hare
The mountain hare (''Lepus timidus''), also known as blue hare, tundra hare, variable hare, white hare, snow hare, alpine hare, and Irish hare, is a Palearctic hare that is largely adapted to polar and mountainous habitats. Evolution The mountain hare arose during the Late Pleistocene; there is evidence that its range expanded during glaciations into southern Europe, with populations of Iberian hare (''Lepus granatensis''), European hare (''L. europaeus)'' and broom hare (''L. castroviejoi'') in northern Iberia harboring mitochondrial haplotypes from the mountain hare. During the Late Pleistocene to Early Holocene, populations of mountain hare in Russia grew at least 10% larger than any living population today. This population has been classified as a distinct species ''Lepus tanaiticus'', but is now generally considered a prehistoric morphotype of the living mountain hare. Distribution This species is distributed from Fennoscandia to eastern Siberia; in addition, isolated mou ...

Lodgepole Pine
''Pinus contorta'', with the common names lodgepole pine and shore pine, and also known as twisted pine, and contorta pine, is a common tree in western North America. It is common near the ocean shore and in dry montane forests to the subalpine, but is rare in lowland rain forests. Like all pines (member species of the genus ''Pinus''), it is an evergreen conifer. Description Depending on subspecies, ''Pinus contorta'' grows as an evergreen shrub or tree. The shrub form is krummholz and is approximately high. The thin and narrow-crowned tree can grow high and achieve up to in diameter at chest height. The ''murrayana'' subspecies is the tallest. The crown is rounded and the top of the tree is flattened. In dense forests, the tree has a slim, conical crown. The formation of twin trees is common in some populations in British Columbia. The elastic branches stand upright or overhang and are difficult to break. The branches are covered with short shoots that are easy to ...

Sitka Spruce
''Picea sitchensis'', the Sitka spruce, is a large, coniferous, evergreen tree growing to almost tall, with a trunk diameter at breast height that can exceed 5 m (16 ft). It is by far the largest species of spruce and the fifth-largest conifer in the world (behind giant sequoia, coast redwood, kauri, and western red cedar), and the third-tallest conifer species (after coast redwood and coast Douglas fir). The Sitka spruce is one of the few species documented to exceed in height. Its name is derived from the community of Sitka in southeast Alaska, where it is prevalent. Its range hugs the western coast of Canada and the US, continuing south into northernmost California. Description The bark is thin and scaly, flaking off in small, circular plates across. The inner bark is reddish-brown. The crown is broad conic in young trees, becoming cylindric in older trees; old trees may not have branches lower than . The shoots are very pale buff-brown, almost white, and glab ...

Coniferous Forest
Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere, but also in similar cool climates in mountains further south. Boreal conifers have many wintertime ada ...

Blanket Bog
Blanket bog or blanket mire, also known as featherbed bog, is an area of peatland, forming where there is a climate of high rainfall and a low level of evapotranspiration, allowing peat to develop not only in wet hollows but over large expanses of undulating ground. The blanketing of the ground with a variable depth of peat gives the habitat type its name. Blanket bogs are found extensively throughout the northern hemisphere - well-studied examples are found in Ireland and Scotland, but vast areas of North American tundra also qualify as blanket bogs. In Europe, the southernmost edge of range of this habitat has been recently mapped in the Cantabrian Mountains, northern Spain, but the current distribution of blanket bogs globally remains unknown. In the southern hemisphere they are less well-developed due to the relatively low latitudes of the main land areas, though similar environments are reported in Patagonia, the Falkland Islands and New Zealand. The blanket bogs known as ...
