Nant-y-Ffrith Footbridge
Nant-y-Ffrith refers to a stream and the wooded valley through which it flows on the border between Flintshire and Wrexham County Borough in Wales. The stream begins in moorland to the east of Llandegla. It passes Bwlchgwyn village before entering a rather steep-sided, rocky valley. It passes under the viaduct of a disused railway line before joining the River Cegidog at Ffrith. The woodlands contain some deciduous trees but are dominated by recent conifer plantations planted by the Forestry Commission after the second world war. They contain a range of flora and fauna including various ferns and mosses and woodland birds such as wood warbler and redstart. During the 1950s, people travelled from miles around to park their cars on the Drofa (or hair-pin bend in English) overlooking Nant-y-Ffrith, and listen to nightingales, whose song echoed in the valley. There are several abandoned silica quarries and lead mines in the area. Lead mining may have begun as early as Roman times a ...

Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns. Ferns first ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dyserth
Dyserth ( cy, Diserth) is a village, community and electoral ward in Denbighshire, Wales. Its population at the 2011 United Kingdom census was 2,269 and was estimated by the Office for National Statistics as 2,271 in 2019. It lies within the historic county boundaries of Flintshire. Features include quarrying remains, waterfalls and the mountain Moel Hiraddug. Its railway line, once part of the London and North Western Railway, finally closed in 1973 and is now a footpath. Overview Dyserth is mentioned in the Domesday book of 1086, listed in the Hundred of Ati's Cross and within Cheshire: Dyserth also had a nearby castle, which suffered at the hands of Llywelyn ap Gruffudd; destroyed after a six-week siege in 1263. The remains of the castle were quarried away during World War I. The oldest industry in the village and surrounding area is mining, with lead, copper and limestone just some of the minerals being mined locally in the past. These quarries are still visible and fo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Rhododendron
''Rhododendron'' (; from Ancient Greek ''rhódon'' "rose" and ''déndron'' "tree") is a very large genus of about 1,024 species of woody plants in the heath family (Ericaceae). They can be either evergreen or deciduous. Most species are native to eastern Asia and the Himalayan region, but smaller numbers occur elsewhere in Asia, and in North America, Europe and Australia. It is the national flower of Nepal, the state flower of Washington and West Virginia in the United States, the state flower of Nagaland in India, the provincial flower of Jiangxi in China and the state tree of Sikkim and Uttarakhand in India. Most species have brightly colored flowers which bloom from late winter through to early summer. Azaleas make up two subgenera of ''Rhododendron''. They are distinguished from "true" rhododendrons by having only five anthers per flower. Species Description ''Rhododendron'' is a genus of shrubs and small to (rarely) large trees, the smallest species growing to t ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hunting And Shooting In The United Kingdom
In the United Kingdom, the term hunting with no qualification generally refers to hunting with hounds, e.g. normally fox hunting, stag (deer) hunting, beagling, or minkhunting, whereas shooting is the shooting of game birds. What is called deer hunting elsewhere is deer stalking. According to the British Association for Shooting and Conservation (BASC) over a million people a year participate in shooting, including stalking, shooting, hunting, clay shooting and target shooting. Firearm ownership is regulated in the UK by licensing. Provisions exist for those without a Firearm or Shotgun certificate to shoot under the supervision of a certificate holder. History Hunting has been practised in Britain since prehistoric times; it was a crucial activity of hunter-gatherer societies before the domestication of animals and the dawn of agriculture. During the last ice age, humans and neanderthals hunted mammoths and woolly rhinoceroses by driving them over cliffs; evidence has been ...

Ancient Rome
In modern historiography, ancient Rome refers to Roman civilisation from the founding of the city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), Roman Republic (509–27 BC) and Roman Empire (27 BC–476 AD) until the fall of the western empire. Ancient Rome began as an Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian Peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually dominated the Italian Peninsula, assimilated the Greek culture of southern Italy ( Magna Grecia) and the Etruscan culture and acquired an Empire that took in much of Europe and the lands and peoples surrounding the Mediterranean Sea. It was among the largest empires in the ancient world, with an estimated 50 to 90 million inhabitants, roughly 20% of t ...

Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Silica
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula , most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as a synthetic product. Notable examples include fused quartz, fumed silica, silica gel, opal and aerogels. It is used in structural materials, microelectronics (as an Insulator (electricity), electrical insulator), and as components in the food and pharmaceutical industries. Structure In the majority of silicates, the silicon atom shows tetrahedral coordination geometry, tetrahedral coordination, with four oxygen atoms surrounding a central Si atomsee 3-D Unit Cell. Thus, SiO2 forms 3-dimensional network solids in which each silicon atom is covalently bonded in a tetrahedral manner to 4 oxygen atoms. In contrast, CO2 is a linear ...

Nightingale
The common nightingale, rufous nightingale or simply nightingale (''Luscinia megarhynchos''), is a small passerine bird best known for its powerful and beautiful song. It was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher, Muscicapidae. It belongs to a group of more terrestrial species, often called chats. Etymology "Nightingale" is derived from "night" and the Old English ''galan'', "to sing". The genus name ''Luscinia'' is Latin for "nightingale" and ''megarhynchos'' is from Ancient Greek ''megas'', "great" and ''rhunkhos'' "bill". Subspecies *western nightingale (''L. m. megarhynchos'') - Western Europe, North Africa and Asia Minor, wintering in tropical Africa *Caucasian nightingale (''L. m. africana'') - The Caucasus and eastern Turkey to southwestern Iran and Iraq, wintering in East Africa *eastern nightingale (''L. m. golzii'') - The Aral Sea to Mongolia, wintering in coastal East Africa ...
