Páramos de North York

As part of the United Kingdom, the North York Moors area generally has warm summers and relatively mild winters. Weather conditions vary from day to day as well as from season to season. The latitude of the area means that it is influenced by predominantly westerly winds with depressions and their associated fronts, bringing with them unsettled and windy weather, particularly in winter. Between depressions, there are often small mobile anticyclones that bring periods of fine weather. In winter, anticyclones bring cold dry weather. In summer, the anticyclones tend to bring dry settled conditions, which can lead to drought. For its latitude, this area is milder in winter and cooler in summer due to the influence of the Gulf Stream in the North Atlantic Ocean. Air temperature varies on a daily and seasonal basis. The temperature is usually lower at night and January is the coldest time of the year. The two dominant influences on the climate of the North York Moors are the shelter against the worst of the moist westerly winds provided by the Pennines and the proximity of the North Sea. Late, chilly springs and warm summers are a feature of the area, but there are often spells of fine autumn weather. Onshore winds in spring and early summer bring mists or low stratus clouds (known locally as sea frets) to the coasts and moorland. Within the area, variations in climate are brought about by local differences in altitude, aspect and shelter.^[11]

Snowfall is variable from year to year, but the area gets much more snow on average than other parts of the country. Heavy falls are associated with northeasterly winds off the North Sea. Roads over the high moorland areas are notoriously prone to drifting snow due to the exposed nature of the terrain.^[12]

Average recordings are:

• 100 wet days
• 215 dry days
• 50 snowfall days ^[13]
• rainfall of 1,000 to 1,520 mm (39 to 60 in) near the coast
• rainfall of 635 to 760 mm (25 to 30 in) inland
• summer temperatures of 20 to 32 °C (68 to 90 °F)
• winter temperatures of −1 to 10 °C (30 to 50 °F)^[14]

La geología de los páramos de North York está dominada por rocas del período Jurásico . Estas se depositaron principalmente en mares subtropicales hace entre 205 y 142 millones de años. Las fluctuaciones del nivel del mar produjeron diferentes tipos de rocas, desde lutitas hasta areniscas y calizas derivadas de coral. Estas rocas marinas y de origen deltaico se encuentran bien expuestas en la costa de Yorkshire, desde Staithes hasta Filey.

• Jurásico Inferior Al comienzo del período Jurásico, se depositaron lutitas, arcillas y finas calizas y areniscas en un mar poco profundo. Estos depósitos tienen varios metros de espesor e incluyen capas de limonita de diversos grosores y las rocas de las quese extrae el alumbre .
• Durante el Jurásico Medio, se produjo un levantamiento gradual en el que se depositaron lutitas y areniscas en una llanura costera baja surcada por grandes ríos. Ocasionalmente, esta zona se inundaba con el mar, depositándose rocas calcáreas con fósiles marinos. Estas rocas conforman el Grupo Ravenscar . La Arcilla de Oxford se depositó al final de esta época.
• Upper Jurassic Towards the end of the Jurassic period the land again sank beneath the sea. At first the sea was shallow and calcareous sandstones and limestones were deposited. These are the Corallian rocks of the Tabular Hills towards the south of the area. Overlying the Corallian rocks is the Kimmeridge Clay which underlies the Vale of Pickering but this is not exposed at the surface.

Subsequently, about 30 million years ago, the land was uplifted and tilted towards the south by earth movements. The upper layers of rock were eroded away and the older rocks were exposed in places. Because of the tilt the oldest rocks became exposed in the north. These are the bands of shales and ironstones on the northern scarp of the North York Moors and Cleveland Hills. The middle layers form the sandstones of the high moorland and the youngest layers of limestone form the Tabular Hills. In the dales, where the rivers have cut through the younger rocks, there are also exposures of older shales, ironstone and sandstone. Rosedale is an example of this.^[17]

During the Quaternary period, the last 2 million years, the area has experienced a sequence of glaciations. The most recent glaciation, the Devensian, ended about 11,000 years ago. The higher parts of the North York Moors were not covered by the ice sheets but glaciers flowed southwards on either side of the higher land mass.

As the climate became warmer at the end of the ice age, the snowfields on the North York Moors began to melt. The meltwater was unable to escape northwards, westwards or eastwards because it was blocked by ice. Huge torrents of water were forced southwards. Water from the Esk valley area flowed southwards gouging out the deep Newtondale valley as it went. Water from the North York Moors formed a vast lake in the area of the Vale of Pickering. Eventually this lake filled its basin and then overflowed at the lowest point which was at Kirkham. Here it cut the steep sided Kirkham gorge. When the ice finally retreated it left deep deposits of boulder clay (or till) behind. The boulder clay blocked the eastern end of the Vale of Pickering causing a permanent deviation in the course of the River Derwent. Alluvium from the glacial meltwater covers many areas to the north of the moors and in the Esk valley.^[17]

Sandstones erode slowly and form poor acid soils which are deficient in nutrients. They are less permeable to water, impeding drainage and encouraging the formation of bogs. Sphagnum moss bogs are common where there is abundant rain and poor drainage. Cotton grass is a distinctive plant which grows in the boggy areas. In the cold acid waters of peat bogs there is little decomposition of organic material with the result that the dead sphagnum moss gradually accumulates to form peat. This raises the levels of the bogs and they dry out. Heather then invades the area. Large areas of the moorland are now covered in heather, bilberries and grasses growing on thick layers of peat.

The acid soils and peat bogs are unsuitable for earthworms so species which usually feed on earthworms such as moles and the common shrew are absent on the moorland. The pygmy shrew survives by eating the insects and spiders that live in the heather. Lapwing, curlew and redshank breed on the moorland and there are sandpipers along the streams. Wheatear and golden plovers inhabit grassier patches on the moorland and ring ouzels live in stony areas. Red grouse, which feed on young heather shoots, are abundant. The heather is burned in strips by gamekeepers and farmers to encourage new heather growth to feed the grouse. Grouse shooting is part of the moorland economy. About 20 per cent of the national park is covered in bracken. Few things can grow under its dense cover and it does not support many insects and is unpalatable to most animals.

Sheep are a ubiquitous part of the moorland landscape. Their grazing helps to maintain the open wild landscape that is needed for many other plants and animals to thrive.^[18]

The North York Moors was once covered in expansive native woodlands entwined with wetland, heathland and bog. Though reforestation efforts are taking place, the regeneration of these ancient woodlands which have been cleared by people over the years have been hindered by overgrazing. Remnants of the ancient, native, woodlands still exist and generally consist of two informal 'types'.

Upland forest is the most widespread native woodland type, consisting of mostly Scots pine and rowan. Other species such as aspen, both downy birch, silver birch, sessile oak, various willow species and a variety of other trees found in Scotland and Northern England. Juniper was also widespread in the North York Moor's uplands, especially in woodland edges, scrubland and heathland growing out of rocky outcrops; this species has seen massive decline in the UK as a whole. The European larch is non-native but naturalised in the UK's uplands and is particularly associated with this national park in the country – it has been recorded to be beneficial to a number species including jays and pine marten. It is said that the park's now extinct populations of red squirrel were often found on larch trees.

The lowland forests of the region found primarily in its dales are home to many of the species found in the uplands, but are also to other species of tree such as pedunculate oak and occasionally the rare wild chequer tree. Yew trees are common too and have heavy ties to the culture and folklore of Yorkshire as a whole.

There is a third major type of woodland: timber plantations. These often consist of the non-native Sitka spruce and Norway spruce and the native Scots pine. The North York Moors National Park is home to two of the largest forests in England, both plantations: Dalby Forest and Cropton Forest; the latter has recently seen the reintroduction of Eurasian beaver.

Fauna in these woodlands is largely the same. Herpetofauna such as adder, common lizard, slowworm, frogs, toads and all three of Britain's native newts can be found here. Various mammals such as red deer, roe deer, fallow deer, pine marten, wood mouse, wild boar and a variety of bats exist in these woodlands just to name a few species. A population of feralBritish primitive goat exists as a remnant of a once larger population.

Limestone weathers quickly to produce nutrient rich alkaline soils on well drained rocks. Gouging by glacial meltwaters has left spectacular valleys along whose floors run streams. The limestone streams with their nutrient rich waters support an abundance of aquatic invertebrates such as insect larvae and crustaceans. These in turn support such fish as trout and grayling. Insects which emerge from the water in summer are also a rich source of food for birds. Grey wagtails, swallows and spotted flycatchers are commonly seen. Dippers and kingfishers are also typical. The otter, after a period of decline, is starting to recolonise the rivers and streams.

Farndale is famous for its wild daffodils in spring. Sheltered woodlands dominated by sessile oaks can be found to the south of the high ground. These woodland areas are the home of pied flycatchers, sparrow hawks and wood warblers. Roe and fallow deer can also be found here. The woodlands and south facing grasslands on the limestone belt provide a good habitat for many butterflies.

The fertile alkaline soils support an abundance of wild flowers. Bluebells and primroses grow in the hedgerows in spring and rarer plants such as the wood vetch and orchids are also to be found. Adders are widespread throughout the national park. On the moors they eat common lizards and around the hedgerows and woodland edges they feed on mice and voles.^[18]

Los pastizales calcáreos albergan una gran variedad de flores silvestres, y se pueden observar muchas mariposas menos comunes. La fritilaria de borde perlado , la fritilaria duque de Borgoña , la blanca jaspeada , la saltarina oscura y la gris son solo algunas de las especies que habitan el parque nacional.

Los acantilados y las bahías arenosas del extremo norte de la costa de Yorkshire ofrecen una gran variedad de hábitats costeros. La zona donde las colinas de Cleveland se encuentran con el mar ha sido declarada Costa Patrimonial . El acantilado de Boulby, con 210 metros de altura (690 pies ) , el punto más alto de la costa este de Inglaterra, está formado por pizarras, arcillas y limonitas del Jurásico. También se pueden observar excelentes afloramientos de rocas jurásicas con sus fósiles característicos en los alrededores de Robin Hood's Bay y Ravenscar. 

Las costas rocosas ofrecen una gran variedad de algas en zonas de distintos tipos, más o menos tolerantes a la exposición al aire y al agua salada o cristalina. Las pozas rocosas albergan anémonas de mar , blénidos , cangrejos y moluscos .

Las costas arenosas albergan una variedad de plantas y animales que se entierran en la arena. Se pueden observar aves como zarapitos y ostreros hurgando en la arena para encontrar estas criaturas como alimento. Algunos cormoranes y fulmares anidan a lo largo de la costa, donde también se pueden avistar collalbas y bisbitas costeras . Las gaviotas argénteas son las aves reproductoras más comunes y ofrecen una vista interesante al anidar en las chimeneas de los pueblos costeros. ^{[ 18 ]} . El sapo partero común se ha introducido en la ciudad costera de Whitby y, en general, no es invasivo, simplemente se suma a la fauna de las costas.

Hacia el año 8000  a. C., Gran Bretaña aún formaba parte del continente europeo, y comunidades de la Edad de Piedra Media emigraron a Inglaterra y comenzaron a habitar los páramos de North York. Se han encontrado vestigios de esta antigua comunidad de cazadores, recolectores y pescadores, como una gran cantidad de herramientas de sílex y lascas de sílex con púas utilizadas en flechas y lanzas.

Hacia el año 5000  a. C., con el aumento del nivel del mar y la formación del Mar del Norte, Gran Bretaña quedó aislada del continente europeo. Durante el Neolítico, que abarcó desde aproximadamente el 4500 hasta el 2000  a. C., la población creció y se adoptó la agricultura. Estos primeros agricultores fueron los primeros en talar los bosques de los páramos. Sus asentamientos se concentraron en las zonas fértiles del cinturón calcáreo, y estas áreas se han cultivado ininterrumpidamente desde entonces. Los agricultores neolíticos cultivaban, criaban animales, fabricaban cerámica y eran muy hábiles en la elaboración de herramientas de piedra. Enterraban a sus muertos en largos y bajos túmulos funerarios.

Hacia el año 2000 a. C., el pueblo de la cultura del vaso campaniforme de  la Edad del Bronce temprana habitó los páramos. Durante un período de 1400 años, estos pobladores ocuparon todas las áreas de los páramos y finalmente destruyeron gran parte del bosque original. El clima era relativamente más cálido y seco en ese entonces, por lo que era posible vivir en los páramos altos durante todo el año. Cuando un terreno se agotaba en nutrientes, estos pobladores se desplazaban, dejando atrás tierras incapaces de sustentar otra vegetación que no fuera la de brezales. Existen alrededor de 3000 túmulos funerarios de la Edad del Bronce en los páramos.

La Edad del Hierro data de alrededor del año 600  a. C. Se conservan restos de dos castros en Boltby Scar y Roulston Scar ^{[ 19 ]} y un conjunto de cimientos circulares de cabañas de piedra en Percy Rigg. Otras evidencias de ocupación durante la Edad del Hierro son escasas, ya que fueron borradas por la actividad agrícola posterior.

Hacia el año 71  d. C., el ejército romano llegó a Yorkshire, donde estableció un fuerte en Malton. La Calzada de Wade pudo haber sido una de las varias calzadas romanas que partían de este punto. Se dirigía hacia el noreste, atravesando el Valle de Pickering y el páramo de Wheeldale, hacia la costa del Mar del Norte. Se conservan campamentos romanos en Cawthorn y Lease Rigg, cerca de Grosmont, y estaciones de señales a lo largo de la costa en Filey, Scarborough, Ravenscar, Goldsborough y Hunt Cliff . Los romanos abandonaron Britania en el año 410  d. C.

After the departure of the Romans, Germanic tribes arrived and settled in the area. These Angles, Saxons and Jutes gave many of the place names to villages on the moors. They worshipped a number of gods, notably Woden. However, Christianity came to Yorkshire when King Edwin of Northumbria was baptised in 627 AD at York. Christian monasteries were established at Lastingham in 654 and Whitby in 657. A nunnery was built at Hackness in 680.

In the 9th century, Viking raiders began to attack the Yorkshire coast, and in 867 these Danes destroyed the religious houses at Whitby, Lastingham and Hackness and after battle set up a new Danish kingdom based at York. The Danes settled in the area and later themselves became Christian. They introduced their language, elements of which still remain in the local dialect, and renamed a number of settlements.

King William I of England and his Norman barons took control of the nation in 1066. Central to the imposition of Norman rule was the building of castles. There are well-preserved castle ruins at Helmsley, Pickering and Scarborough and others existed at Ayton, Danby, Mulgrave and Whorlton. In the 11th and 12th centuries monasteries were established on the moors at Whitby Abbey, Rievaulx Abbey, Byland Abbey and Mount Grace Priory. Gifts of land and money were bestowed on these establishments and the monastic orders became notable landowners, eventually owning about a third of the land in the area. The abbeys managed their land as sheep farms and became very rich on the profits. They continued to take in land from the waste and what remained of the forest and in the process gave the moors the distinctive landscape that still remains. Between 1536 and 1541, Henry VIII of Englanddissolved the monasteries, and confiscated and sold off their property. This was bought by individual people, some rich, but also some who had been tenants of the monasteries, and became privately owned land.

A wide network of routeways (hollow ways and 'trods' – paved routeways made of flagstones) extend across the North York Moors. While many are medieval in date, some may even pre-date the Roman period.^[21]

In many areas of the moors and their associated dales the settlements took the form of isolated farms and hamlets rather than villages. Very few had an open field system of agriculture so Enclosure Acts were rarer than in other parts of England. The 17th century saw a major acceleration in the reclaiming of marginal waste land and in the eighteenth century forward looking landlords attempted to improve their lands using drainage schemes and fertilisation measures.^[22]

In the 19th century railways were built from Pickering to Whitby (1836), Middlesbrough to Whitby (1868) and Scarborough to Whitby (1884).

Locally sourced iron ore has been processed on the North York Moors from medieval times. In the 19th century it became a boom industry. Dozens of ironstone mines and several short-lived blast furnaces were constructed. Between 1856 and 1926 high-grade magnetic ironstone was mined in Rosedale. A railway was built around the top of the dale to serve the mines, and kilns were built to process the ore. In two decades the population of the valley rose from 558 to nearly 3000. Poor-quality coal was mined in many places on the moors from the 18th century to the early 20th century.

The North York Moors is the only source for British jet. It has been mined in the area from prehistoric times but the industry grew in the middle of the 19th century in response to a fashion for the jewellery produced from it. In the 1880s cheap imports produced a decline in the industry which was focused on Whitby. The remains of alum quarries are to be found to the north of the area and along the coast. Alum was important to the textile industry because it was used as a mordant or fixative for dyes that were used to colour cloth. The industry thrived in the region from the early 17th century until 1871. Its decline came when chemical dyes were discovered. The scars of industrial activity on the moors make it an interesting area in which to pursue industrial archaeology.^[23]

For over a thousand years the basis of the economy in the North York Moors was agriculture. The rural scene, which attracts millions of visitors to the park each year, has been formed and maintained by generations of farmers. The 1996 Agricultural Census recorded a total workforce of 2,913 employed on 1,342 working farms. Sheep and cattle provide the prime source of farm income. The dale farms have rights to graze sheep on the open moor. The rights to moorland grazing are often essential to the economic viability of a farm. In recent years agriculture in Britain has suffered economic setbacks and the viability of hill farming has become questionable. A number of environmental schemes to improve farm incomes have been devised but the industry continues to decline.

Agricultural use of the moors is shared with grouse shooting as a means of gaining financial return from the vast expanse of heather. There is richer farmland across the southern limestone belt, where there are arable and mixed farms as well as the livestock farms. The main arable crops are barley, wheat, oilseed rape, potatoes, and sugar beets. There is also some intensive production of pigs and poultry.^[17]

Many visitors to the North York Moors are engaged in outdoor pursuits, particularly walking; the National Park has a network of public rights of way almost 1,400 miles (2,300 km) in length, and most of the areas of open moorland are open access under the Countryside and Rights of Way Act 2000. Popular named walks include the Cleveland Way, which circles the North York Moors, including a coastal section; and the Lyke Wake Walk, which leads directly across the heart of the National Park. The route of the White Rose Way, a long distance walk from Leeds to Scarborough also passes through.

The area also offers opportunities for cycling, mountain biking, and horse-riding, including a circular long distance bridle route created around the North York Moors which can be accessed at a number of locations.^[24] The steep escarpments that define the edges of the National Park on three sides are used by several gliding clubs.

In late 2020, the National Park was named as an International Dark Sky Reserve. This honour confirms that the area has "low levels of light pollution with good conditions for astronomy".^[25]

The National Park has two visitor centres which have tourist information and exhibitions, as well as a contemporary gallery.^[26] These are at:

• Sutton Bank
• The Moors National Park Centre, Danby

The North York Moors have not changed much in the past 50 years, and are often used as a location for British television programmes and films.

The series Heartbeat and the scenes of Hogsmeade Station in the Harry Potter movies were filmed in Goathland. Parts of Phantom Thread (2017) were filmed in Lythe,^[27][28] with a number of other locations in the North York Moors, including Robin Hood's Bay and Staithes.^[29] The film version of Downton Abbey shot some scenes at the Pickering station of North Yorkshire Moors Railway. The Runaways with Mark Addy (2020), The Secret Garden with Colin Firth and Julie Walters (2020) and Miss Willoughby and the Haunted Bookshop with Kelsey Grammer, Caroline Quentin and Nathalie Cox (2020) were all partly filmed in the National Park.^[30]

Dalby Forest is also host to many forms of entertainment throughout the year including outdoor concerts.

There are few major settlements within, or around, the National Park: Helmsley, Pickering, Kirkbymoorside, Guisborough, Stokesley, Northallerton and Whitby. The North York Moors are within a reasonable distance of Redcar and form part of East Cleveland, and are within 20 minutes' driving time from central Middlesbrough and Scarborough.
