Context: Hiking is the preferred term, in Canada and the United States, for a long, vigorous walk, usually on trails (footpaths), in the countryside, while the word walking is used for shorter, particularly urban walks. On the other hand, in the United Kingdom, and the Republic of Ireland, the word "walking" is acceptable to describe "all forms" of walking, whether it is a walk in the park or backpacking in the Alps. The word hiking is also often used in the UK, along with rambling (a slightly old-fashioned term), hillwalking, and fell walking (a term mostly used for hillwalking in northern England). In New Zealand a long, vigorous walk or hike is called tramping. It is a popular activity with numerous worldwide, and studies suggest that all forms of walking have health benefits., Shrubland, scrubland, scrub or brush is a plant community characterised by vegetation dominated by shrubs, often also including grasses, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term "shrubland" was first coined in 1903., Mountain bike racing (shortened MTB or ATB racing) is a competitive cycle sport held on off-road terrain. The Union Cycliste Internationale (UCI) recognised the discipline relatively late in 1990, when it sanctioned the world championships in Durango, Colorado. The first UCI Mountain Bike World Cup series took place in 1988. Its nine-race circuit covered two continentsEurope and North Americaand was sponsored by Grundig. Cross-country racing was the only World Cup sport at this time. In 1993, a six-event downhill World Cup was introduced. In 1996, cross-country mountain biking events were added to the Olympic Games. In 2006, cross-country mountain biking events became part of the World Deaf Cycling Championships for the first time in San Francisco, USA., A tributary or affluent is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean., Ireland, also described as the Republic of Ireland ('), is a sovereign state in north-western Europe occupying about five-sixths of the island of Ireland. The capital and largest city is Dublin, which is located on the eastern part of the island, and whose metropolitan area is home to around a third of the country's 4.75 million inhabitants. The state shares its only land border with Northern Ireland, a part of the United Kingdom. It is otherwise surrounded by the Atlantic Ocean, with the Celtic Sea to the south, Saint George's Channel to the south-east, and the Irish Sea to the east. It is a unitary, parliamentary republic. The legislature, the ', consists of a lower house, ', an upper house, ', and an elected President (') who serves as the largely ceremonial head of state, but with some important powers and duties. The head of government is the ' (Prime Minister, literally 'Chief', a title not used in English), who is elected by the Dáil and appointed by the President, and appoints other government ministers., A mountain bike or mountain bicycle (abbreviated Mtn Bike, MTB; or ATB, for all-terrain bicycle) is a bicycle designed for off-road cycling. Mountain bikes share similarities with other bikes, but incorporate features designed to enhance durability and performance in rough terrain. These typically include suspension on the frame and fork, large knobby tires, more durable heavy duty wheels, more powerful brakes, and lower gear ratios needed for steep grades with poor traction., A habitat is an ecological or environmental area that is inhabited by a particular species of animal, plant, or other type of organism. The term typically refers to the zone in which the organism lives and where it can find food, shelter, protection and mates for reproduction. It is the natural environment in which an organism lives, or the physical environment that surrounds a species population., The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union., A country is a region that is identified as a distinct national entity in political geography. A country may be an independent sovereign state or one that is occupied by another state, as a non-sovereign or formerly sovereign political division, or a geographic region associated with sets of previously independent or differently associated people with distinct political characteristics. Regardless of the physical geography, in the modern internationally accepted legal definition as defined by the League of Nations in 1937 and reaffirmed by the United Nations in 1945, a resident of a country is subject to the independent exercise of legal jurisdiction., Woodland is a low-density forest forming open habitats with plenty of sunlight and limited shade. Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are referred to as forests. , FOREST (short for "Freedom Organisation for the Right to Enjoy Smoking Tobacco") is a United Kingdom political pressure group which campaigns against tobacco control activity., The Bristol Channel is a major inlet in the island of Great Britain, separating South Wales from Devon and Somerset in South West England. It extends from the lower estuary of the River Severn to the North Atlantic Ocean. It takes its name from the English city of Bristol, and is over 30 miles (50 km) across at its widest point., Dolgellau (formerly "Dolgell(e)y" ; see below) is a market town in Gwynedd, north-west Wales, lying on the River Wnion, a tributary of the River Mawddach. It was the county town of Merionethshire before that became a part of the county of Gwynedd. Dolgellau is the main base for climbers of Cader Idris., Wales is a country that is part of the United Kingdom and the island of Great Britain. It is bordered by England to the east, the Irish Sea to the north and west, and the Bristol Channel to the south. It had a population in 2011 of 3,063,456 and has a total area of . Wales has over of coastline and is largely mountainous, with its higher peaks in the north and central areas, including Snowdon, its highest summit. The country lies within the north temperate zone and has a changeable, maritime climate., The Alps are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across eight Alpine countries: Austria, France, Germany, Italy, Liechtenstein, Monaco, Slovenia, and Switzerland. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the FrenchItalian border, and at is the highest mountain in the Alps. The Alpine region area contains about a hundred peaks higher than 4000 metres (just over 13,000 feet)., In the field of cell biology, TNF-related apoptosis-inducing ligand (TRAIL), is a protein functioning as a ligand that induces the process of cell death called apoptosis., A fell (from Old Norse "fell", "fjall", "mountain") is a high and barren landscape feature, such as a mountain range or moor-covered hills. The term is most often employed in Fennoscandia, the Isle of Man, parts of Northern England, and Scotland., Walking (also known as ambulation) is one of the main gaits of locomotion among legged animals, and is typically slower than running and other gaits. Walking is defined by an 'inverted pendulum' gait in which the body vaults over the stiff limb or limbs with each step. This applies regardless of the number of limbs - even arthropods, with six, eight or more limbs, walk., Tobacco control is a field of international public health science, policy and practice dedicated to addressing tobacco use and thereby reducing the morbidity and mortality it causes. Tobacco control is a priority area for the World Health Organization (WHO), through the Framework Convention on Tobacco Control. References to a tobacco control movement may have either positive or negative connotations, both briefly covered here., Great Britain, also known as Britain , is a large island in the north Atlantic Ocean off the northwest coast of continental Europe. With an area of , Great Britain is the largest European island and the ninth-largest in the world. In 2011 the island had a population of about 61 million people, making it the world's third-most populous island after Java in Indonesia and Honshu in Japan. The island of Ireland is situated to the west of it, and together these islands, along with over 1,000 smaller surrounding islands, comprise the British Isles archipelago., Coed - y - Brenin ( Welsh for King 's Trees ) is a forest in the Snowdonia National Park , North Wales near Dolgellau at grid reference SH7127 . It is popular for its mountain bike trails and hiking paths . It has several man - made mountain bike singletrack courses in a woodland setting , varying in length from 12 to 38 km ( 7 to 23 mi ) , and one dual slalom course . The site is owned and operated by Forest Enterprise Wales , part of the Forestry Commission , and covers an area of some 9,000 acres ( 36 km² ) around the valleys of the rivers Mawddach , Eden , Gain and Wen . There is no charge for using the trails . The site was identified as a potential mountain bike race course in 1990 , and the first races were held there in 1991 . The initial course had to be chopped out of an impassable rock - strewn terrain . Shortly afterwards an MTB hire centre , together with a visitor centre and café were opened at Maesgwm . Five waymarked trails were developed by Dafydd Davis who was employed by Forest Enterprise as a Forest Sports Development Adviser , grew Coed - y - Brenin into a major UK mountain biking centre . Davis received an MBE in the 2004 Queen 's Birthday Honours list for ' services to forestry ' relating to his work on this resort . A new £ 1.6 million visitor centre opened in summer 2006 . There are also a number of waymarked walking trails around the forest ., A shrub or bush is a small to medium-sized woody plant. It is distinguished from a tree by its multiple stems and shorter height, usually under 6 m (20 ft) tall. Plants of many species may grow either into shrubs or trees, depending on their growing conditions. Small, low shrubs, generally less than 2 m (6.6 ft) tall, such as lavender, periwinkle and most small garden varieties of roses, are often termed subshrubs., England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight., Gwynedd is an area in north-west Wales, named after the old Kingdom of Gwynedd. As a local government area, it is the second biggest in Wales in terms of geographical area and also one of the most sparsely populated. A majority of the population are Welsh-speaking. The name Gwynedd is also used for a preserved county, covering the two local government areas of Gwynedd and the Isle of Anglesey. Culturally and historically, the name can also be used for most of North Wales (for instance, the area covered by the Gwynedd Constabulary), roughly corresponding to the territory of the Kingdom of Gwynedd at its greatest extent. The current area is 2,548 square km (983.78 sq miles, slightly smaller than Luxembourg) with a population as measured in the 2011 Census of 121,874., Secondary succession is one of the two types of ecological succession of plant life. As opposed to the first, primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting soil whereas primary succession usually occurs in a place lacking soil., Dual slalom is an older mountain bike racing discipline similar to 4X racing., The Irish Sea (, , , Ulster-Scots: "Airish Sea"), separates the islands of Ireland and Great Britain. It is connected to the Celtic Sea in the south by St George's Channel, and to the Inner Seas off the West Coast of Scotland in the north by the North Channel. Anglesey is the largest island within the Irish Sea, followed by the Isle of Man. The sea is occasionally, but rarely, referred to as the Manx Sea., Merionethshire or Merioneth (or "") is one of thirteen historic counties of Wales, a vice county and a former administrative county., Yr Wyddfa commonly known as Snowdon in English, is the highest mountain in Wales, at an elevation of above sea level, and the highest point in the British Isles south of the Scottish Highlands. It is located in Snowdonia National Park (") in Gwynedd, and has been described as "probably the busiest mountain in Britain". It is designated as a national nature reserve for its rare flora and fauna., A County town is usually the location of administrative or judicial functions within the county, or it has been established over time as the "de facto" main town of a county. The concept of a county town eventually became detached from its original meaning of where the county administration or county hall is based. In fact, many county towns are no longer part of the administrative county. For example, Nottingham is administered by a unitary authority entirely separate from the rest of Nottinghamshire. Many county towns are classified as cities, but all are referred to as county towns regardless of whether city status is held or not., Subject: coed-y-brenin, Relation: located_in_the_administrative_territorial_entity, Options: (A) alpine (B) anglesey (C) atlantic ocean (D) basin (E) bristol (F) british isles (G) canada (H) central (I) devon (J) dublin (K) east (L) england (M) europe (N) forest (O) freedom (P) gwynedd (Q) ireland (R) isle of man (S) italy (T) japan (U) java (V) liechtenstein (W) mainland (X) merionethshire (Y) most (Z) mountain ([) new zealand (\) north (]) north america (^) northern (_) northern ireland (`) northwest (a) nottingham (b) of (c) river (d) roses (e) san francisco (f) scotland (g) slovenia (h) somerset (i) south (j) switzerland (k) time (l) ulster (m) united kingdom (n) wales (o) woodland (p) woodlands
