Silver Flowe-Merrick Kells
Situated in south-west Scotland, the Silver Flowe-Merrick Kells biosphere reserve is composed of two separate sites. Silver Flowe is a unique bog formation and one of the least interrupted undisturbed mire systems in Europe. Its high value is principally due to the landscape pattern of an assemblage of discrete mires. It is also a breeding site for the rare Azure Hawker dragonfly. Silver Flowe is also designated as Ramsar site. Merrick Kells contains three habitats of European interest: blanket bog, montane acid grasslands, and wet heath with cross-leaved heath. There are mires supporting various communities, and the area has a wide variety of species but low population levels. There are nationally important breeding bird populations, and important invertebrate populations. The site is the largest remaining unafforested area of upland in Galloway. Both sites are surrounded by commercial coniferous forestry. The management of Merrick Kells and Silver Flowe is mainly carried ...

Silver Flowe From Dungeon Hill
Silver is a chemical element with the symbol Ag (from the Latin ', derived from the Proto-Indo-European ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures.

Seville Strategy For Biosphere Reserves
Seville (; es, Sevilla, ) is the capital and largest city of the Spanish autonomous community of Andalusia and the province of Seville. It is situated on the lower reaches of the River Guadalquivir, in the southwest of the Iberian Peninsula. Seville has a municipal population of about 685,000 , and a metropolitan population of about 1.5 million, making it the largest city in Andalusia, the fourth-largest city in Spain and the 26th most populous municipality in the European Union. Its old town, with an area of , contains three UNESCO World Heritage Sites: the Alcázar palace complex, the Cathedral and the General Archive of the Indies. The Seville harbour, located about from the Atlantic Ocean, is the only river port in Spain. The capital of Andalusia features hot temperatures in the summer, with daily maximums routinely above in July and August. Seville was founded as the Roman city of . Known as ''Ishbiliyah'' after the Islamic conquest in 711, Seville became the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nardus Spp
''Nardus'' is a genus of plants belonging to the grass family, containing the single species ''Nardus stricta'', known as matgrass. It is placed in its own tribe Nardeae within the subfamily Pooideae. The name derives from ancient Greek ' () from the earlier Akkadian ''lardu''. It is not to be confused with spikenard, ''Nardostachys jatamansi''. Distribution and ecology ''Nardus stricta'' is native to Eurasia (from Iceland and the Azores to Mongolia), North Africa (Algeria, Morocco), and northeastern North America (Greenland, eastern Canada, and the northeastern United States). ''Nardus stricta'' occurs on heath, moorland, hills, and mountains on nutrient poor acidic sandy to peaty soils and is strongly calcifuge, avoiding calcareous soils. It can occur from low elevations to over , becoming a community-dominant in late snow patches on mountains. ''Nardus stricta'' may also become a dominant species in habitats grazed by cattle or sheep because it is tough and unpalatable. It fl ...

Submontane
Foothills or piedmont are geographically defined as gradual increases in elevation at the base of a mountain range, higher hill range or an upland area. They are a transition zone between plains and low relief hills and the adjacent topographically higher mountains, hills, and uplands. Frequently foothills consist of alluvial fans, coalesced alluvial fans, and dissected plateaus. Description Foothills primarily border mountains, especially those which are reached through low ridges that increase in size closer and closer to the mountain, but can also border uplands and higher hills. Examples Areas where foothills exist, or areas commonly referred to as the foothills, include the: * Sierra Nevada foothills of California, USA * Foothills of the San Gabriel Valley in Los Angeles County, California, USA *Rocky Mountain Foothills in British Columbia and Alberta, Canada *Silesian Foothills in Silesia, Poland *Sivalik Hills along the Himalayas in the Indian subcontinent * Catalin ...

Campylopus Atrovirens
''Campylopus'' is a genus of 180 species of haplolepideous mosses (Dicranidae) in the family Leucobryaceae. The name comes from the Greek ''campylos'', meaning curved, and ''pous'', meaning foot, referring to the setae which curve downwards. Distribution The genus is represented worldwide, with species found in North America, Mexico, West Indies, Central America, South America, Europe, Asia, Africa, Atlantic Islands, Pacific Islands, and Australia. ''Campylopus bicolor'' is an example found in Australia. The North American list of species from the genus was revised by Jan-Peter Frahm in 1980. This was based on his own study of over 1,000 herbarium specimens. The most recent checklist of the mosses of North America lists 18 species as being present in North American flora. However, due to a misidentification, there are only 17 accepted species in the region. Species Species adapted from The Plant List; *''Campylopus abbreviatus'' *''Campylopus acicularis'' *'' Campylopus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleurozia Purpurea
''Pleurozia purpurea'' is a species of thalloid liverwort, notable for its red to purple colour. Common names of the species include purple-worm liverwort and purple spoonwort. Geographic distribution ''Pleurozia purpurea'' grows in bog environments found worldwide. The locations this species has been found in includes the following: "western Scotland and western Ireland, Norway, Faroes, Jan Meyen Island, Himalayas, Alaska, Guadeloupe, Hawaii". Habitat ''Pleurozia purpurea'' often grows on the edges of bogs, fens and pools. However, it can also be found growing on lawns and other water saturated regions at high elevations, such as a "blanket bog, wet heath, montane turf, scree and peat-covered rock ledges". This species will grow in a matted form across the aforementioned water surfaces. Morphology In general, this thalloid liverwort is composed of worm like thallus, that often form a creeping mat; these mats can be branched or unbranched. Evident by its name, ''P. pur ...

Drosera Anglica
''Drosera anglica'', commonly known as the English sundew or great sundew, is a carnivorous flowering plant species belonging to the sundew family Droseraceae. It is a temperate species with a circumboreal range, although it does occur as far south as Japan, southern Europe, and the island of Kauai in Hawaii, where it grows as a tropical sundew. It is thought to originate from an amphidiploid hybrid of '' D. rotundifolia'' and '' D. linearis'', meaning that a sterile hybrid between these two species doubled its chromosomes to produce fertile progeny which stabilized into the current ''D. anglica''. Morphology ''Drosera anglica'' is a perennial herb which forms an upright, stemless rosette of generally linear-spatulate leaves. As is typical for sundews, the laminae are densely covered with stalked reddish colored mucilaginous glands, each tipped with a clear droplet of a viscous fluid used for trapping insects. The lamina, which is long, is held semi-erect by a long petiole ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sphagnum Plumulosum
''Sphagnum'' is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, peat moss, also bog moss and quacker moss (although that term is also sometimes used for peat). Accumulations of ''Sphagnum'' can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 to 26 times as much water as their dry weight, depending on the species.Bold, H. C. 1967. Morphology of Plants. second ed. Harper and Row, New York. p. 225-229. The empty cells help retain water in drier conditions. As sphagnum moss grows, it can slowly spread into drier conditions, forming larger mires, both raised bogs and blanket bogs. Thus, sphagnum can influence the composition of such habitats, with some describing sphagnum as 'habitat manipulators'. These peat accumulations then provide habitat for a wide array of peatland plants, including sedges and ericaceous shrubs, as well as orchids and carnivorous plants.Keddy, P. ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Flowe
Silver Flowe is an area of patterned blanket mire in the Galloway Hills, in Dumfries and Galloway, Scotland. Located around 16 km north northeast of Newton Stewart, it forms part of the Galloway Forest Park. An area of 620 hectares has been designated as a Ramsar Site. The site is one of the least-disturbed and most varied areas of acid peatland in southern Scotland.
