Allt Y Benglog
Allt y Benglog is a small national nature reserve (United Kingdom), national nature reserve near Dolgellau in Wales. Its position on the lower slopes of Rhobell Fawr, one of north Wales’ extinct volcanoes, results in an unusual mix of plants and trees which spring from its subterranean mix of volcanic rocks. A permanently damp atmosphere is created through a combination of numerous waterfalls and good tree coverage, and allows an unusually rich variety of moisture-loving mosses, plants and trees to thrive.

Bracken In A Woodland Clearing At Allt Y Benglog National Nature Reserve - Geograph
Bracken (''Pteridium'') is a genus of large, coarse ferns in the family Dennstaedtiaceae. Ferns (Pteridophyta) are vascular plants that have alternating generations, large plants that produce spores and small plants that produce sex cells (eggs and sperm). Brackens are noted for their large, highly divided leaves. They are found on all continents except Antarctica and in all environments except deserts, though their typical habitat is moorland. The genus probably has the widest distribution of any fern in the world. The word ''bracken'' is of Old Norse origin, related to Swedish ''bräken'' and Danish ''bregne'', both meaning fern. In the past, the genus was commonly treated as having only one species, ''Pteridium aquilinum'', but the recent trend is to subdivide it into about ten species. Like other ferns, brackens do not have seeds or fruits, but the immature fronds, known as ''fiddleheads'', are sometimes eaten, although some are thought to be carcinogenic. Description and ...

National Nature Reserve (United Kingdom)
Some statutory nature reserves are designated by national bodies in the United Kingdom, and are known as national nature reserves. Great Britain In Great Britain, nature reserves designed under Part III of the National Parks and Access to the Countryside Act 1949 that are deemed to be of national importance may be designated as statutory 'national nature reserves' by the relevant national nature conservation body (Natural England, Scottish Natural Heritage, or Natural Resources Wales) using section 35(1) of the Wildlife and Countryside Act 1981. If a nature reserve is designated by a local authority in Great Britain, then the resulting statutory nature reserve will be referred to as a local nature reserve. England In England, 229 national nature reserves are designated by Natural England. Scotland In Scotland, 43 national nature reserves are designated by NatureScot. Wales In Wales, 76 national nature reserves are designated by Natural Resources Wales. Northern Ireland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolgellau
Dolgellau () is a town and community in Gwynedd, north-west Wales, lying on the River Wnion, a tributary of the River Mawddach. It was the traditional county town of the historic county of Merionethshire ( cy, Meirionnydd, Sir Feirionnydd) until the county of Gwynedd was created in 1974. Dolgellau is the main base for climbers of Cadair Idris and Mynydd Moel which are visible from the town. Dolgellau is the second largest settlement in southern Gwynedd after Tywyn and includes the community of Penmaenpool. Etymology The name of the town is of uncertain origin, although ' is Welsh for "meadow" or "dale", and ' (soft mutation of ') means "grove" or "spinney", and is common locally in names for farms in sheltered nooks. This would seem to be the most likely derivation, giving the translation "Grove Meadow". It has also been suggested that the name could derive from the word ', meaning "cell", translating therefore as "Meadow of onks'cells", but this seems less likely considering ...

Wales
Wales ( cy, Cymru ) is a Countries of the United Kingdom, country that is part of the United Kingdom. It is bordered by England to the Wales–England border, east, the Irish Sea to the north and west, the Celtic Sea to the south west and the Bristol Channel to the south. It had a population in 2021 of 3,107,500 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 Temperateness, north temperate zone and has a changeable, maritime climate. The capital and largest city is Cardiff. Welsh national identity emerged among the Celtic Britons after the Roman withdrawal from Britain in the 5th century, and Wales was formed as a Kingdom of Wales, kingdom under Gruffydd ap Llywelyn in 1055. Wales is regarded as one of the Celtic nations. The Conquest of Wales by Edward I, conquest of Wales by Edward I of England was completed by 1283, th ...

Rhobell Fawr
Rhobell Fawr is the site of an ancient volcano that was active during the Early Ordovician period in the Arenig range within the Snowdonia National Park. Despite its modest height of 734 m (2,408 feet), it is a mountain with views of higher peaks all around, including the north face of Cadair Idris and distant Snowdon. The paths are not well trodden, but there is a distinct path up from Bwlch Goriwared, a couple of miles north-north-east of the small village of Llanfachreth Llanfachreth is a settlement approximately three miles north-east of Dolgellau, Gwynedd, in the community of Brithdir and Llanfachreth within the historic boundaries of Merionethshire ( cy, Meirionnydd, Sir Feirionnydd), Wales.

Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

Volcanic Rock
Volcanic rock (often shortened to volcanics in scientific contexts) is a rock formed from lava erupted from a volcano. In other words, it differs from other igneous rock by being of volcanic origin. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks. For these reasons, in geology, volcanics and shallow hypabyssal rocks are not always treated as distinct. In the context of Precambrian shield geology, the term "volcanic" is often applied to what are strictly metavolcanic rocks. Volcanic rocks and sediment that form from magma erupted into the air are called "volcaniclastics," and these are technically sedimentary rocks. Volcanic rocks are among the most common rock types on Earth's surface, particularly in the oceans. On land, they are very common at plate boundaries and in flood basalt provinces. It has been estimated t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterfall
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which Erosion, erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Mosses
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) ''sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are app ...

National Nature Reserves In Wales
National nature reserves in Wales are selected and designated by Natural Resources Wales (NRW) (formerly the Countryside Council for Wales). There are 76 reserves all of which are also SSSIs, they cover , or less than 1.5% of the land area of Wales. They range in size from Dan yr Ogof at to Berwyn which covers . A national nature reserve is designated because of its special biological, geological, habitat or landscape value and most in Wales are open to the public. They include upland and lowland areas, several offshore islands and in some cases estuarine and intertidal zones. Management Although the majority of sites are managed by NRW, a number are managed by other bodies, mainly in the public and wildlife charity sectors, including: List of national nature reserves in Wales {, , {, class="wikitable sortable" , - ! scope="col" , Name ! scope="col" , Region/area ! scope="col" , Reserve manager , - , Aberbargoed Grasslands , , Southeast , , Caerphilly , - , Allt ...

Nature Reserves In Gwynedd
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-So ...
