Derryclare Nature Reserve
Derryclare () is a mountain at the southern edge of Twelve Bens mountain range in Connemara National Park in County Galway, Ireland. At , it is the 119th–highest peak in Ireland on the Arderin list, and the 145th–highest peak on the Vandeleur-Lynam list.Mountainviews, (September 2013), "A Guide to Ireland's Mountain Summits: The Vandeleur-Lynams & the Arderins", Collins Books, Cork, It is the 5th tallest of the core '' Twelve Bens''. The Derryclare Lough on its southern slopes is a scenic location in Connemara, while Derryclare Wood, on its eastern slopes, contains a ''Statutory Nature Reserve'' (SRN). Derryclare's prominence of does not qualify it as a Marilyn, however, it does rank as the 72nd-highest mountain in Ireland on the MountainViews Online Database, '' 100 Highest Irish Mountains'', where the minimum prominence threshold is 100 metres. Naming The name "Derryclare" comes from Irish ''Doire Chláir''; means "an oak wood", and can mean either a "plain" or a " ...

Derryclare Lough
Derryclare Lough () is a freshwater lake at the entrance of the Inagh Valley, in Connemara, Galway, in the west of Ireland. Geography Derryclare Lough is located about east of Clifden on the N59 road. The Twelve Bens mountain range lies to the north of the lake, with the Ben of Derryclare overlooking the lake itself. Derryclare Lough is fed from rivers from Lough Inagh, which itself is fed from several mountain streams in the area, but most importantly from the ''Gleninagh River'' that starts high up in the ''Gleninagh Valley'' on the slopes of Benbaun and Bencollaghduff, and the ''Tooreennacoona River''. Derryclare Lough flows into Ballynahinch Lake, where it eventually joins the Owenmore River, and flows into Bertraghboy Bay. Fishing Derryclare Lough is noted for its lake and river fishing with spring salmon, grilse and sea trout, and the fishing is done from "Butts" (e.g. long piers from the shore), and particularly the ''Derryclare Butts'', ''Glendollagh Butts'', and t ...

U-shaped Valley
U-shaped valleys, also called trough valleys or glacial troughs, are formed by the process of glaciation. They are characteristic of mountain glaciation in particular. They have a characteristic U shape in cross-section, with steep, straight sides and a flat or rounded bottom (by contrast, valleys carved by rivers tend to be V-shaped in cross-section). Glaciated valleys are formed when a glacier travels across and down a slope, carving the valley by the action of scouring. When the ice recedes or thaws, the valley remains, often littered with small boulders that were transported within the ice, called glacial till or glacial erratic. Examples of U-shaped valleys are found in mountainous regions throughout the world including the Andes, Alps, Caucasus Mountains, Himalaya, Rocky Mountains, New Zealand and the Scandinavian Mountains. They are found also in other major European mountains including the Carpathian Mountains, the Pyrenees, the Rila and Pirin mountains in Bulgaria, an ...

Canopy Layer
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, canopy also refers to the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms ( epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Sometimes the term canopy is used to refer to the extent of the outer layer of leaves of an individual tree or group of trees. Shade trees normally have a dense canopy that blocks light from lower growing plants. Observation Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs sus ...

Ash Tree
''Fraxinus'' (), commonly called ash, is a genus of flowering plants in the olive and lilac family, Oleaceae. It contains 45–65 species of usually medium to large trees, mostly deciduous, though a number of subtropical species are evergreen. The genus is widespread across much of Europe, Asia, and North America. The leaves are opposite (rarely in whorls of three), and mostly pinnately compound, though simple in a few species. The seeds, popularly known as "keys" or "helicopter seeds", are a type of fruit known as a samara. Some ''Fraxinus'' species are dioecious, having male and female flowers on separate plants but sex in ash is expressed as a continuum between male and female individuals, dominated by unisexual trees. With age, ash may change their sexual function from predominantly male and hermaphrodite towards femaleness ; if grown as an ornamental and both sexes are present, ashes can cause a considerable litter problem with their seeds. Rowans or mountain ashes ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Downy Birch
''Betula pubescens'' (syn. ''Betula alba''), commonly known as downy birch and also as moor birch, white birch, European white birch or hairy birch, is a species of deciduous tree, native and abundant throughout northern Europe and northern Asia, growing farther north than any other broadleaf tree. It is closely related to, and often confused with, the silver birch (''B. pendula''), but grows in wetter places with heavier soils and poorer drainage; smaller trees can also be confused with the dwarf birch (''B. nana''). Six varieties are recognised and it hybridises with the silver and dwarf birches. A number of cultivars have been developed but many are no longer in cultivation. The larva of the autumnal moth (''Epirrita autumnata'') feeds on the foliage and in some years, large areas of birch forest can be defoliated by this insect. Many fungi are associated with the tree and certain pathogenic fungi are the causal agents of birch dieback disease. The tree is a pioneer species ...

Sessile Oak
''Quercus petraea'', commonly known as the sessile oak, Cornish oak, Irish Oak or durmast oak, is a species of oak tree native to most of Europe and into Anatolia and Iran. The sessile oak is the national tree of Ireland, and an unofficial emblem in Wales and Cornwall. Description The sessile oak is a large deciduous tree up to tall, in the white oak section of the genus (''Quercus'' sect. ''Quercus'') and similar to the pedunculate oak (''Q. robur''), with which it overlaps extensively in range. The leaves are long and broad, evenly lobed with five to six lobes on each side and a petiole. The male flowers are grouped into catkins, produced in the spring. The fruit is an acorn long and broad, which matures in about six months. Comparison with pedunculate oak Significant botanical differences from pedunculate oak (''Q. robur'') include the stalked leaves, and the stalkless (sessile) acorns from which one of its common names is derived. It occurs in uplan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadleaf Tree
A broad-leaved, broad-leaf, or broadleaf tree is any tree within the diverse botanical group of angiosperms that has flat leaves and produces seeds inside of fruits. It is one of two general types of trees, the other being a conifer, a tree with needle-like or scale-like leaves and seeds borne in woody cones. Broad-leaved trees are sometimes known as hardwoods. Most deciduous trees are broad-leavedLee, S. and A. RafloTrees and Water. Virginia Water Resources Research Center. Virginia Tech. but some are coniferous, like larches.

Conifer
Conifers are a group of conifer cone, cone-bearing Spermatophyte, seed plants, a subset of gymnosperms. Scientifically, they make up the phylum, division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class (biology), class, Pinopsida. All Neontology, extant conifers are perennial plant, perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include Cedrus, cedars, Pseudotsuga, Douglas-firs, Cupressaceae, cypresses, firs, junipers, Agathis, kauri, larches, pines, Tsuga, hemlocks, Sequoioideae, redwoods, spruces, and Taxaceae, 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.

Broadleaf Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...
