A hedge or hedgerow is a line of closely spaced shrubs and sometimes trees, planted and trained to form a barrier or to mark the boundary of an area, such as between neighbouring properties. Hedges that are used to separate a road from adjoining fields or one field from another, and are of sufficient age to incorporate larger trees, are known as hedgerows. Often they serve as windbreaks to improve conditions for the adjacent crops, as in bocage country. When clipped and maintained, hedges are also a simple form of topiary.

A hedge often operates as, and sometimes is called, a "live fence". This may either consist of individual fence posts connected with wire or other fencing material, or it may be in the form of densely planted hedges without interconnecting wire. This is common in tropical areas where low-income farmers can demarcate properties and reduce maintenance of fence posts that otherwise deteriorate rapidly. Many other benefits can be obtained depending on the species chosen.[1]

Shrub

Shrub

A shrub is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than 6–10 m (20–33 ft) tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead.

Tree

Tree

In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees.

Windbreak

Windbreak

A windbreak (shelterbelt) is a planting usually made up of one or more rows of trees or shrubs planted in such a manner as to provide shelter from the wind and to protect soil from erosion. They are commonly planted in hedgerows around the edges of fields on farms. If designed properly, windbreaks around a home can reduce the cost of heating and cooling and save energy. Windbreaks are also planted to help keep snow from drifting onto roadways or yards. Farmers sometimes use windbreaks to keep snow drifts on farm land that will provide water when the snow melts in the spring. Other benefits include contributing to a microclimate around crops, providing habitat for wildlife, and, in some regions, providing wood if the trees are harvested.

Microclimate

Microclimate

A microclimate is a local set of atmospheric conditions that differ from those in the surrounding areas, often slightly but sometimes substantially. The term may refer to areas as small as a few square meters or smaller or as large as many square kilometers. Because climate is statistical, which implies spatial and temporal variation of the mean values of the describing parameters, within a region there can occur and persist over time sets of statistically distinct conditions, that is, microclimates. Microclimates can be found in most places but are most pronounced in topographically dynamic zones such as mountainous areas, islands, and coastal areas.

Crop

Crop

A crop is a plant that can be grown and harvested extensively for profit or subsistence. When the plants of the same kind are cultivated at one place on a large scale, it is called a crop. Most crops are cultivated in agriculture or hydroponics. Crops may include macroscopic fungus and marine macroalga, some of which are grown in aquaculture.

Bocage

Bocage

Bocage is a terrain of mixed woodland and pasture characteristic of parts of northern France, southern England, Ireland, the Netherlands and northern Germany, in regions where pastoral farming is the dominant land use.

Topiary

Topiary

Topiary is the horticultural practice of training perennial plants by clipping the foliage and twigs of trees, shrubs and subshrubs to develop and maintain clearly defined shapes, whether geometric or fanciful. The term also refers to plants which have been shaped in this way. As an art form it is a type of living sculpture. The word derives from the Latin word for an ornamental landscape gardener, topiarius, a creator of topia or "places", a Greek word that Romans also applied to fictive indoor landscapes executed in fresco.

Fence

Fence

A fence is a structure that encloses an area, typically outdoors, and is usually constructed from posts that are connected by boards, wire, rails or netting. A fence differs from a wall in not having a solid foundation along its whole length.

History

The development of hedges over the centuries is preserved in their structure. The first hedges enclosed land for cereal crops during the Neolithic Age (4000–6000 years ago). The farms were of about 5 to 10 hectares (12 to 25 acres), with fields about 0.1 hectares (0.25 acres) for hand cultivation. Some hedges date from the Bronze and Iron Ages, 2000–4000 years ago, when traditional patterns of landscape became established. Others were built during the Medieval field rationalisations; more originated in the industrial boom of the 18th and 19th centuries, when heaths and uplands were enclosed.

Many hedgerows separating fields from lanes in the United Kingdom, Ireland and the Low Countries are estimated to have been in existence for more than seven hundred years, originating in the medieval period. The root word of 'hedge' is much older: it appears in the Old English language, in German (Hecke), and Dutch (haag) to mean 'enclosure', as in the name of the Dutch city The Hague, or more formally 's Gravenhage, meaning The Count's hedge. Charles the Bald is recorded as complaining in 864, at a time when most official fortifications were constructed of wooden palisades, that some unauthorized men were constructing haies et fertés; tightly interwoven hedges of hawthorns.[2]

In parts of Britain, early hedges were destroyed to make way for the manorial open-field system. Many were replaced after the Enclosure Acts, then removed again during modern agricultural intensification, and now some are being replanted for wildlife.

Bronze Age

Bronze Age

The Bronze Age is a historic period, lasting approximately from 3300 BC to 1200 BC, characterized by the use of bronze, the presence of writing in some areas, and other early features of urban civilization. The Bronze Age is the second principal period of the three-age system proposed in 1836 by Christian Jürgensen Thomsen for classifying and studying ancient societies and history.

Iron Age

Iron Age

The Iron Age is the final epoch of the three-age division of the prehistory and protohistory of humanity. It was preceded by the Stone Age and the Bronze Age. The concept has been mostly applied to Iron Age Europe and the Ancient Near East, but also, by analogy, to other parts of the Old World.

Enclosure

Enclosure

Enclosure or Inclosure is a term, used in English landownership, that refers to the appropriation of "waste" or "common land" enclosing it and by doing so depriving commoners of their rights of access and privilege. Agreements to enclose land could be either through a formal or informal process. The process could normally be accomplished in three ways. First there was the creation of "closes", taken out of larger common fields by their owners. Secondly, there was enclosure by proprietors, owners who acted together, usually small farmers or squires, leading to the enclosure of whole parishes. Finally there were enclosures by Acts of Parliament.

United Kingdom

United Kingdom

The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is 242,495 square kilometres (93,628 sq mi), with an estimated 2023 population of over 68 million people.

Ireland

Ireland

Ireland is an island in the North Atlantic Ocean, in north-western Europe. It is separated from Great Britain to its east by the North Channel, the Irish Sea, and St George's Channel. Ireland is the second-largest island of the British Isles, the third-largest in Europe, and the twentieth-largest in the world.

Low Countries

Low Countries

The term Low Countries, also known as the Low Lands and historically called the Netherlands, Flanders, or Belgica, is a coastal lowland region in Northwestern Europe forming the lower basin of the Rhine–Meuse–Scheldt delta and consisting of three countries: Belgium, the Netherlands and Luxembourg. Geographically and historically, the area also includes parts of France and Germany such as French Flanders and the German regions of East Frisia and Cleves. During the Middle Ages, the Low Countries were divided into numerous semi-independent principalities.

The Hague

The Hague

The Hague is a city and municipality of the Netherlands, situated on the west coast facing the North Sea. The Hague is the country's administrative centre and its seat of government, and while the official capital of the Netherlands is Amsterdam, The Hague has been described as the country's de facto capital. The Hague is also the capital of the province of South Holland, and the city hosts both the International Court of Justice and the International Criminal Court.

Count

Count

Count is a historical title of nobility in certain European countries, varying in relative status, generally of middling rank in the hierarchy of nobility. Especially in earlier medieval periods the term often implied not only a certain status, but also that the count had specific responsibilities or offices. The etymologically related English term "county" denoted the territories associated with some countships, but not all.

Charles the Bald

Charles the Bald

Charles the Bald, also known as Charles II, was a 9th-century king of West Francia (843–877), king of Italy (875–877) and emperor of the Carolingian Empire (875–877). After a series of civil wars during the reign of his father, Louis the Pious, Charles succeeded, by the Treaty of Verdun (843), in acquiring the western third of the empire. He was a grandson of Charlemagne and the youngest son of Louis the Pious by his second wife, Judith.

Palisade

Palisade

A palisade, sometimes called a stakewall or a paling, is typically a fence or defensive wall made from iron or wooden stakes, or tree trunks, and used as a defensive structure or enclosure. Palisades can form a stockade.

Composition

A hedge may consist of a single species or several, typically mixed at random. In many newly planted British hedges, at least 60 per cent of the shrubs are hawthorn, blackthorn, and (in the southwest) hazel, alone or in combination. The first two are particularly effective barriers to livestock. In North America, Maclura pomifera (i.e., hedge apple) was grown to form a barrier to exclude free-range livestock from vegetable gardens and corn fields.[3] Other shrubs and trees used include holly, beech, oak, ash, and willow; the last three can become very tall.[4] Of the hedgerows in the Normandy region of France, Martin Blumenson said,

The hedgerow is a fence, half earth, half hedge. The wall at the base is a dirt parapet that varies in thickness from one to four or more feet and in height from three to twelve feet. Growing out of the wall is a hedge of hawthorn, brambles, vines, and trees, in thickness from one to three feet. Originally property demarcations, hedgerows protect crops and cattle from the ocean winds that sweep across the land.[5]

The hedgerows of Normandy became barriers that slowed the advance of Allied troops following the D-Day invasion during World War II. Allied armed forces modified their armored vehicles to facilitate breaking out of their beachheads into the Normandy bocage.

Species

Formal, or modern garden hedges are grown in many varieties, including the following species:

Hedgerow trees

Hedgerow trees are trees that grow in hedgerows but have been allowed to reach their full height and width. There are thought to be around 1.8 million hedgerow trees in Britain (counting only those whose canopies do not touch others) with perhaps 98% of these being in England and Wales.[6] Hedgerow trees are both an important part of the English landscape and valuable habitats for wildlife.[6] Many hedgerow trees are veteran trees and therefore of great wildlife interest.

The most common species are English oak (Quercus robur) and ash (Fraxinus excelsior), though in the past field elm (Ulmus minor 'Atinia') would also have been common. Around 20 million elm trees, most of them hedgerow trees, were felled or died through Dutch elm disease in the late 1960s. Many other species are used, notably including common beech (Fagus sylvatica) and various nut and fruit trees.[6]

The age structure of British hedgerow trees is old because the number of new trees is not sufficient to replace the number of trees that are lost through age or disease.[6]

New trees can be established by planting but it is generally more successful to leave standard trees behind when laying hedges. Trees should be left at no closer than 10 metres (33 ft) apart and the distances should vary so as to create a more natural landscape.[6] The distance allows the young trees to develop full crowns without competing or producing too much shade.[6]

It is suggested that hedgerow trees cause gaps in hedges but it has been found that cutting some lower branches off lets sufficient light through to the hedge below to allow it to grow.[6]

Corylus avellana

Corylus avellana

Corylus avellana, the common hazel, is a species of flowering plant in the birch family Betulaceae. It is native to Europe and western Asia. It is an important component of the hedgerows that were the traditional field boundaries in lowland England. The wood was traditionally grown as coppice, the poles cut being used for wattle-and-daub building and agricultural fencing.

Maclura pomifera

Maclura pomifera

Maclura pomifera, commonly known as the Osage orange, is a small deciduous tree or large shrub, native to the south-central United States. It typically grows about 8 to 15 metres (30–50 ft) tall. The distinctive fruit, a multiple fruit, is roughly spherical, bumpy, 8 to 15 centimetres (3–6 in) in diameter, and turns bright yellow-green in the fall. The fruits secrete a sticky white latex when cut or damaged. Despite the name "Osage orange", it is not related to the orange. It is a member of the mulberry family, Moraceae. Due to its latex secretions and woody pulp, the fruit is typically not eaten by humans and rarely by foraging animals. Ecologists Daniel H. Janzen and Paul S. Martin proposed in 1982 that the fruit of this species might be an example of what has come to be called an evolutionary anachronism—that is, a fruit coevolved with a large animal seed dispersal partner that is now extinct. Evidence and arguments pro and con their hypothesis followed for decades afterwards.

Ilex aquifolium

Ilex aquifolium

Ilex aquifolium, the holly, common holly, English holly, European holly, or occasionally Christmas holly, is a species of flowering plant in the family Aquifoliaceae, native to western and southern Europe, northwest Africa, and southwest Asia. It is regarded as the type species of the genus Ilex, which by association is also called "holly". It is an evergreen tree or shrub found, for example, in shady areas of forests of oak and in beech hedges. In the British Isles it is one of very few native hardwood evergreen trees. It has a great capacity to adapt to different conditions and is a pioneer species that repopulates the margins of forests or clearcuts.

Fagus sylvatica

Fagus sylvatica

Fagus sylvatica, the European beech or common beech is a deciduous tree belonging to the beech family Fagaceae.

Fraxinus excelsior

Fraxinus excelsior

Fraxinus excelsior, known as the ash, or European ash or common ash to distinguish it from other types of ash, is a flowering plant species in the olive family Oleaceae. It is native throughout mainland Europe east to the Caucasus and Alborz mountains, and Britain and Ireland, the latter determining its western boundary. The northernmost location is in the Trondheimsfjord region of Norway. The species is widely cultivated and reportedly naturalised in New Zealand and in scattered locales in the United States and Canada.

Allies of World War II

Allies of World War II

The Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during the Second World War (1939–1945) to oppose the Axis powers, led by Nazi Germany, Imperial Japan, and Fascist Italy. Its principal members by the end of 1941 were the United Kingdom, United States, Soviet Union, and China.

Beachhead

Beachhead

A beachhead is a temporary line created when a military unit reaches a landing beach by sea and begins to defend the area as other reinforcements arrive. Once a large enough unit is assembled, the invading force can begin advancing inland. The term is sometimes used interchangeably with bridgehead and lodgement. Beachheads were important in many military actions; examples include operations such as Operation Neptune during World War II, the Korean War, and the Vietnam War.

Berberis thunbergii

Berberis thunbergii

Berberis thunbergii, the Japanese barberry, Thunberg's barberry, or red barberry, is a species of flowering plant in the barberry family Berberidaceae, native to Japan and eastern Asia, though widely naturalized in China and North America, where it has become a problematic invasive in many places, leading to declines in species diversity, increased tick habitat, and soil changes. Growing to 1 m tall by 2.5 m broad, it is a small deciduous shrub with green leaves turning red in the autumn, brilliant red fruits in autumn and pale yellow flowers in spring.

Buxus sempervirens

Buxus sempervirens

Buxus sempervirens, the common box, European box, or boxwood, is a species of flowering plant in the genus Buxus, native to western and southern Europe, northwest Africa, and southwest Asia, from southern England south to northern Morocco, and east through the northern Mediterranean region to Turkey. Buxus colchica of western Caucasus and B. hyrcana of northern Iran and eastern Caucasus are commonly treated as synonyms of B. sempervirens.

Carpinus betulus

Carpinus betulus

Carpinus betulus, the European or common hornbeam, is a species of tree in the birch family Betulaceae, native to Western Asia and central, eastern, and southern Europe, including southern England. It requires a warm climate for good growth, and occurs only at elevations up to 1,000 metres (3,281 ft). It grows in mixed stands with oak, and in some areas beech, and is also a common tree in scree forests. Hornbeam was also known as yoke elm.

Crataegus monogyna

Crataegus monogyna

Crataegus monogyna, known as common hawthorn, one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family Rosaceae. It is native to Europe, northwestern Africa, and West Asia, but has been introduced in many other parts of the world.

Importance of hedgerows

Hedges are recognised as part of a cultural heritage and historical record and for their great value to wildlife[7] and the landscape. Increasingly, they are valued too for the major role they have to play in preventing soil loss and reducing pollution, and for their potential to regulate water supply and to reduce flooding.[8] There is increased earthworm diversity in the soils under hedgerows which also help to store organic carbon and support distinct communities of arbuscular mycorrhizal (AM) fungi.[9]

In addition to maintaining the health of the environment, hedgerows also play a huge role in providing shelter for smaller animals like birds and insects.[10] Recent study by Emma Coulthard mentioned the possibility that hedgerows may act as guides for moths, like Acronicta rumicis, when flying from one location to another. As moths are nocturnal, it is highly unlikely that they use visual aids as guides, but rather are following sensory or olfactory markers on the hedgerows.[11] Larkin et al. 2013 find 100% of northwest European farms have hedges, providing 43% of the wildlife habitat there.[7]

Historically, hedges were used as a source of firewood, and for providing shelter from wind, rain and sun for crops, farm animals and people. Today, mature hedges' uses include screening unsightly developments.[8]

In England and Wales agricultural hedgerow removal is controlled by the Hedgerows Regulations 1997, administered by the local planning authority.

Hedges that have existed for hundreds of years are colonised by additional species. This may be useful as a means of determining the age of the hedge. Hooper's rule (named for Dr. Max Hooper) is based on ecological data obtained from hedges of known age, and suggests that the age of a hedge can be roughly estimated by counting the number of woody species counted in a thirty-yard distance and multiplying by 110 years.[12]

Max Hooper published his original formula in the book Hedges in 1974. This method is only a rule of thumb, and can be off by a couple of centuries; it should always be backed up by documentary evidence, if possible, and take into account other factors. Caveats include the fact that planted hedgerows, hedgerows with elm, and hedgerows in the north of England tend not to follow the rule as closely. The formula also does not work on hedges more than a thousand years old.

Hooper's scheme is important not least for its potential use in determining what an important hedgerow is, given their protection in The Hedgerows Regulations (1997; No. 1160) of the Department of the Environment, based on age and other factors.[13]

Removal

Hedgerow removal is part of the transition of arable land from low-intensity to high-intensity farming. The removal of hedgerows gives larger fields making the sowing and harvesting of crops easier, faster and cheaper, and giving a larger area to grow the crops, increasing yield and profits.

Hedgerows serve as important wildlife corridors, especially in the United Kingdom where they link the country's fractured ancient woodland. They also serve as a habitat for birds and other animals. As the land within a few metres of hedges is difficult to plough, sow, or spray with herbicides, the land around hedges also typically includes high plant biodiversity. Hedges also serve to stabilise the soil and on slopes help prevent soil creep and leaching of minerals and plant nutrients. Removal thus weakens the soil and leads to erosion.

In the United Kingdom hedgerow removal has been occurring since World War I as technology made intensive farming possible, and the increasing population demanded more food from the land. The trend has slowed down somewhat since the 1980s when cheap food imports reduced the demand on British farmland, and as the European Union Common Agricultural Policy made environmental projects financially viable. Under reforms to national and EU agricultural policies the environmental impact of farming features more highly and in many places hedgerow conservation and replanting is taking place.

In England and Wales agricultural hedgerow removal is controlled by the Hedgerows Regulations 1997, administered by the local planning authority.

Acronicta rumicis, the knot grass moth, is a species of moth which is part of the genus Acronicta and family Noctuidae. It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is found in the Palearctic region. A. rumicis lives and feeds on plants located in wide-open areas. At its larval stage, as a caterpillar, it causes such a large impact as a crop pest that it has received much attention and research. A. rumicis feeds on maize, strawberries and other herbaceous plants.

Elm

Elm

Elms are deciduous and semi-deciduous trees comprising the flowering plant genus Ulmus in the plant family Ulmaceae. They are distributed over most of the Northern Hemisphere, inhabiting the temperate and tropical-montane regions of North America and Eurasia, presently ranging southward in the Middle East to Lebanon and Israel, and across the Equator in the Far East into Indonesia.

Arable land

Arable land

Arable land is any land capable of being ploughed and used to grow crops. Alternatively, for the purposes of agricultural statistics, the term often has a more precise definition:Arable land is the land under temporary agricultural crops, temporary meadows for mowing or pasture, land under market and kitchen gardens and land temporarily fallow. The abandoned land resulting from shifting cultivation is not included in this category. Data for 'Arable land' are not meant to indicate the amount of land that is potentially cultivable.

Intensive farming

Intensive farming

Intensive agriculture, also known as intensive farming, conventional, or industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of agricultural land area. It is characterized by a low fallow ratio, higher use of inputs such as capital and labour, and higher crop yields per unit land area.

Bird

Bird

Birds are a group of warm-blooded vertebrates constituting the class Aves, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the 5.5 cm (2.2 in) bee hummingbird to the 2.8 m common ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming.

Herbicide

Herbicide

Herbicides, also commonly known as weed killers, are substances used to control undesired plants, also known as weeds. Selective herbicides control specific weed species while leaving the desired crop relatively unharmed, while non-selective herbicides can be used to clear waste ground, industrial and construction sites, railways and railway embankments as they kill all plant material with which they come into contact. Apart from selective/non-selective, other important distinctions include persistence, means of uptake, and mechanism of action. Historically, products such as common salt and other metal salts were used as herbicides, however, these have gradually fallen out of favor, and in some countries, a number of these are banned due to their persistence in soil, and toxicity and groundwater contamination concerns. Herbicides have also been used in warfare and conflict.

Biodiversity

Biodiversity

Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic, species, and ecosystem level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural processes that sustain life.

Hedge laying

If hedges are not maintained and trimmed regularly, gaps tend to form at the base over many years. In essence, hedgelaying consists of cutting most of the way through the stem of each plant near the base, bending it over and interweaving or pleaching it between wooden stakes. This also encourages new growth from the base of each plant. Originally, the main purpose of hedgelaying was to ensure the hedge remained stock-proof. Some side branches were also removed and used as firewood.

The maintenance and laying of hedges to form an impenetrable barrier for farm animals is a skilled art. In Britain there are many local hedgelaying traditions, each with a distinct style. Hedges are still being laid today[14] not only for aesthetic and functional purposes but also for their ecological role in helping wildlife and protecting against soil erosion.

Hedge trimming

An alternative to hedge laying is trimming using a tractor-mounted flail cutter or circular saw, or a hedge trimmer.[15] The height of the cutting can be increased a little every year. Trimming a hedge helps to promote bushy growth. If a flail cutter is used, then the flail must be kept sharp to ensure that the cutting is effective on the hedge. The disadvantage of this is that the hedge species takes a number of years before it will flower again and subsequently bear fruit for wildlife and people.[16] If the hedge is trimmed repeatedly at the same height, a 'hard knuckle' will start to form at that height – similar to the shape of a pollarded tree. Additionally, hedge trimming causes habitat destruction to species like the small eggar moth which spend nearly their entire life cycle in blackthorn and hawthorn hedgerow. This has led to a decline in the moth's population. It is now nationally scarce in Britain.[17]

General hedge management

A 'hedgerow management' scale has been devised by an organisation called Hedgelink UK[18] ranging from 1 to 10. '1' describes the action to take for a heavily over trimmed hedge, '5' is a healthy dense hedgerow more than 2 metres in height, and '10' is a hedge that has not been managed at all and has become a line of trees.

The RSPB suggest that hedges in Britain not be cut between March and August. This is to protect nesting birds, which are protected by law.[19]

Coppicing

The techniques of coppicing and hard pollarding can be used to rejuvenate a hedge where hedge-laying is not appropriate.[20]

Middleton, Northamptonshire

Middleton is a village and civil parish in North Northamptonshire close to the county boundary with Leicestershire. At the time of the 2001 census, the parish's population was 328 people, increasing to 414 at the 2011 Census.

Pleaching

Pleaching

Pleaching or plashing is a technique of interweaving living and dead branches through a hedge creating a fence, hedge or lattices. Trees are planted in lines, and the branches are woven together to strengthen and fill any weak spots until the hedge thickens. Branches in close contact may grow together, due to a natural phenomenon called inosculation, a natural graft. Pleach also means weaving of thin, whippy stems of trees to form a basketry effect.

Wildlife

Wildlife

Wildlife refers to undomesticated animal species, but has come to include all organisms that grow or live wild in an area without being introduced by humans. Wildlife was also synonymous to game: those birds and mammals that were hunted for sport. Wildlife can be found in all ecosystems. Deserts, plains, grasslands, woodlands, forests, and other areas, including the most developed urban areas, all have distinct forms of wildlife. While the term in popular culture usually refers to animals that are untouched by human factors, most scientists agree that much wildlife is affected by human activities. Some wildlife threaten human safety, health, property, and quality of life. However, many wild animals, even the dangerous ones, have value to human beings. This value might be economic, educational, or emotional in nature.

Soil erosion

Soil erosion

Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, and animals. In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolean) erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion. Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. The loss of soil from farmland may be reflected in reduced crop production potential, lower surface water quality and damaged drainage networks. Soil erosion could also cause sinkholes.

Mission San Juan Capistrano

Mission San Juan Capistrano

Mission San Juan Capistrano is a Spanish mission in San Juan Capistrano, Orange County, California. Founded November 1, 1776 in colonial Las Californias by Spanish Catholic missionaries of the Franciscan Order, it was named for Saint John of Capistrano. The Spanish Colonial Baroque style church was located in the Alta California province of the Viceroyalty of New Spain. The Mission was founded less than 60 yards from the village of Acjacheme. The Mission was secularized by the Mexican government in 1833, and returned to the Roman Catholic Church by the United States government in 1865. The Mission was damaged over the years by a number of natural disasters, but restoration and renovation efforts date from around 1910. It functions today as a museum.

California

California

California is a state in the Western United States, located along the Pacific Coast. With nearly 39.2 million residents across a total area of approximately 163,696 square miles (423,970 km2), it is the most populous U.S. state and the third-largest by area. It is also the most populated subnational entity in North America and the 34th most populous in the world. The Greater Los Angeles and San Francisco Bay areas are the nation's second and fifth most populous urban regions respectively, with the former having more than 18.7 million residents and the latter having over 9.6 million. Sacramento is the state's capital, while Los Angeles is the most populous city in the state and the second most populous city in the country. San Francisco is the second most densely populated major city in the country. Los Angeles County is the country's most populous, while San Bernardino County is the largest county by area in the country. California borders Oregon to the north, Nevada and Arizona to the east, the Mexican state of Baja California to the south; and it has a coastline along the Pacific Ocean to the west.

Hedge trimmer

Hedge trimmer

A hedge trimmer, shrub trimmer, or bush trimmer is a gardening tool or machine used for trimming hedges or solitary shrubs (bushes). Different designs as well as manual and powered versions of hedge trimmers exist. Hedge trimmers vary between small hand-held devices to larger trimmers mounted on tractors.

Eriogaster lanestris

Eriogaster lanestris

Eriogaster lanestris, commonly known as the small eggar, is a moth of the family Lasiocampidae that is found across the Palearctic. Unlike many other members of the Lasiocampidae, the small eggar is a social insect. Historically, only eusocial insects like ants, bees, and termites were thought to exhibit complex social organization and communication systems. However, research since the late 20th century has found that E. lanestris, among a number of other phylogenetically related moth and butterfly species, demonstrates social behaviors as well. Larvae spend nearly their entire development in colonies of about 200 individuals, and this grouped social structure offers a number of benefits, from thermoregulation to increased foraging success.

Coppicing

Coppicing

Coppicing is a traditional method of woodland management which exploits the capacity of many species of trees to put out new shoots from their stump or roots if cut down. In a coppiced wood, which is called a copse, young tree stems are repeatedly cut down to near ground level, resulting in a stool. New growth emerges, and after a number of years, the coppiced tree is harvested, and the cycle begins anew. Pollarding is a similar process carried out at a higher level on the tree in order to prevent grazing animals from eating new shoots. Daisugi, is a similar Japanese technique.

Pollarding

Pollarding

Pollarding is a pruning system involving the removal of the upper branches of a tree, which promotes the growth of a dense head of foliage and branches. In ancient Rome, Propertius mentioned pollarding during the 1st century BC. The practice has occurred commonly in Europe since medieval times, and takes place today in urban areas worldwide, primarily to maintain trees at a determined height or to place new shoots out of the reach of grazing animals.

Types

Instant hedge

The term instant hedge has become known since early this century for hedging plants that are planted collectively in such a way as to form a mature hedge from the moment they are planted together, with a height of at least 1.2 metres. They are usually created from hedging elements or individual plants which means very few are actually hedges from the start, as the plants need time to grow and entwine to form a real hedge.

An example of an instant hedge can be seen at the Elveden Hall Estate in East Anglia,[21] where fields of hedges can be seen growing in cultivated rows, since 1998. The development of this type of mature hedge has led to such products being specified by landscape architects, garden designers, property developers, insurance companies, sports clubs, schools and local councils, as well as many private home owners. Demand has also increased from planning authorities in specifying to developers that mature hedges are planted rather than just whips (a slender, unbranched shoot or plant).

A 'real' instant hedge could be defined as having a managed root growth system allowing the hedge to be sold with a continuous rootstrips (rather than individual plants) which then enables year-round planting. During its circa 8-year production time, all stock should be irrigated, clipped and treated with controlled-release nutrients to optimise health.

Quickset hedge

A quickset hedge is a type of hedge created by planting live whitethorn (common hawthorn) cuttings directly into the earth (hazel does not sprout from cuttings).[22] Once planted, these cuttings root and form new plants, creating a dense barrier. The technique is ancient, and the term quickset hedge is first recorded in 1484.[23] The word quick in the name refers to the fact that the cuttings are living (as in "the quick and the dead"), and not to the speed at which the hedge grows, although it will establish quite rapidly. An alternative meaning of quickset hedging is any hedge formed of living plants or of living plants combined with a fence. The technique of quicksetting can also be used for many other shrubs and trees.

Devon hedge

A Devon hedge is an earth bank topped with shrubs. The bank may be faced with turf or stone. When stone-faced, the stones are generally placed on edge, often laid flat around gateways.

A quarter of Devon's hedges are thought to be over 800 years old.[24] There are approximately 33,000 miles (53,000 km) of Devon hedge,[24] which is more than any other county. Traditional farming throughout the county has meant that fewer Devon hedges have been removed than elsewhere.

Devon hedges are particularly important for wildlife habitat. Around 20% of the UK's species-rich hedges occur within Devon.[25] Over 600 species of flowering plants, 1500 species of insects, 65 species of birds and 20 species of mammals have been recorded living or feeding in Devon hedges.[25]

Hedge laying in Devon is usually referred to as steeping and involves cutting and laying steepers (the stems) along the top of the bank and securing them with crooks (forked sticks).

Cornish hedge

A Cornish hedge is an earth bank with stones.[26] It normally consists of large stone blocks constructed either side of a narrow earth bank, and held in place with interlocking stones. The neat rows of square stones at the top are called "edgers". The top of the hedge is planted with grass turf.[27]

Sometimes hedging plants or trees are planted on the hedge to increase its windbreaking height. A rich flora develops over the lifespan of a Cornish hedge. The Cornish hedge contributes to the distinctive field-pattern of the Cornish landscape and its semi-natural wildlife habitat. There are about 30,000 miles (48,000 km) of hedges in Cornwall today.[28]

Hedges suffer from the effects of tree roots, burrowing rabbits, rain, wind, farm animals and people. How often repairs are needed depends on how well the hedge was built, its stone, and what has happened to it since it was last repaired. Typically a hedge needs a cycle of repair every 150 years or so, or less often if it is fenced. Building new hedges, and repairing existing hedges, is a skilled craft, and there are professional hedgers in Cornwall. The Cornish Hedge Research and Education Group (CHREG) supports the development of traditional skills and works with Cornwall Council, FWAG (Farming and Wildlife Advisory Group), Stone Academy Bodmin, Cornwall AONB, Country Trust and professional hedgers to ensure the future of Cornish Hedges in the landscape.

The quick and the dead (idiom)

The quick and the dead (idiom)

The Quick and the Dead is an English phrase originating in William Tyndale's English translation of the New Testament (1526), "I testifie therfore before god and before the lorde Iesu Christ which shall iudge quicke and deed at his aperynge in his kyngdom" [2 Tim 4:1], and used by Thomas Cranmer in his translation of the Nicene Creed and Apostles' Creed for the first Book of Common Prayer (1540). In the following century the idiom was referenced both by Shakespeare's Hamlet (1603) and the King James Bible (1611). More recently the final verse of The Book of Mormon, refers to "...the Eternal Judge of both quick and dead".

Devon is a ceremonial, non-metropolitan, and historic county in South West England. Devon is coastal with a variety of cliffs and sandy beaches. It has the largest open space in southern England, Dartmoor National Park. A predominately rural county, Devon has a relatively low population density for a county in England. Its most populous settlement is the City of Plymouth. The county town of Devon, the City of Exeter, is the second most populous settlement. The county is bordered by Somerset to the north east, Dorset to the east, and Cornwall to the west. Its economy is heavily orientated around the tourism and agriculture industries.

Cornish hedge

Cornish hedge

A Cornish hedge is a style of hedge built of stone and earth found in Cornwall, south-west England. Sometimes hedging plants or trees are planted on the hedge to increase its windbreaking height. A rich flora develops over the lifespan of a Cornish hedge. The Cornish hedge contributes to the distinctive field-pattern of the Cornish landscape, and form the county's largest semi-natural wildlife habitat.

Windbreak

Windbreak

A windbreak (shelterbelt) is a planting usually made up of one or more rows of trees or shrubs planted in such a manner as to provide shelter from the wind and to protect soil from erosion. They are commonly planted in hedgerows around the edges of fields on farms. If designed properly, windbreaks around a home can reduce the cost of heating and cooling and save energy. Windbreaks are also planted to help keep snow from drifting onto roadways or yards. Farmers sometimes use windbreaks to keep snow drifts on farm land that will provide water when the snow melts in the spring. Other benefits include contributing to a microclimate around crops, providing habitat for wildlife, and, in some regions, providing wood if the trees are harvested.

Cornwall Council

Cornwall Council

Cornwall Council is the unitary authority for Cornwall in the United Kingdom, not including the Isles of Scilly, which has its own unitary council. The council, and its predecessor Cornwall County Council, has a tradition of large groups of independent councillors, having been controlled by independents in the 1970s and 1980s. Since the 2021 elections, it has been under the control of the Conservative Party.

In gardening

Hedges, both clipped and unclipped, are often used as ornament in the layout of gardens. Typical woody plants for clipped hedges include privet, hawthorn, beech, yew, leyland cypress, hemlock, arborvitae, barberry, box, holly, oleander, lavender, among others. An early 20th-century fashion was for tapestry hedges, using a mix of golden, green and glaucous dwarf conifers, or beech and copper beech. Unclipped hedges take up more space, generally at a premium in modern gardens, but compensate by flowering. Rosa multiflora is widely used as a dense hedge along the central reservation of dual-carriageway roads, such as parkways in the United States. In mild climates, more exotic flowering hedges are formed, using Ceanothus, Hibiscus, Camellia, orange jessamine (Murraya paniculata),[1] or lillypilly (Syzygium species). It is also possible to prepare really nice and dense hedge from other deciduous plants, however they do not have decorative flowers as the bushes mentioned before.

Hedges of clipped trees forming avenues are a feature of 16th-century Italian gardens such as the Boboli Gardens in Florence, and of formal French gardens in the manner of André Le Nôtre, e.g. in the Gardens of Versailles, where they surround bosquets or areas formalized woodland. The English version of this was the wilderness, normal in large gardens until the English landscape garden style and the rise of the shrubbery began to sweep them away from about 1750.[29] The 'hedge on stilts' of clipped hornbeams at Hidcote Manor Garden, Gloucestershire, is famous and has sometimes been imitated; it is fact a standard French and Italian style of the bosquet.

Hedges below knee height are generally thought of as borders. Elaborately shaped and interlaced borders forming knot gardens or parterres were fashionable in Europe during the 16th and early 17th centuries. Generally they were appreciated from a raised position, either the windows of a house, or a terrace.

Clipped hedges above eye level may be laid out in the form of a labyrinth or garden maze. Few such mazes survived the change of fashion towards more naturalistic plantings in the 18th and 19th centuries, but many were replanted in 20th-century restorations of older gardens. An example is behind the Governor's Palace, Colonial Williamsburg, Virginia.

Hedges and pruning can both be used to enhance a garden's privacy, as a buffer to visual pollution and to hide fences. A hedge can be aesthetically pleasing, as in a tapestry hedge, where alternate species are planted at regular intervals to present different colours or textures.

In America, fences have always been more common than hedges to mark garden boundaries. The English radical William Cobbett was already complaining about this in 1819:

And why should America not possess this most beautiful and useful plant [the Haw-Thorn]? She has English gew-gaws, English Play-Actors, English Cards and English Dice and Billiards; English fooleries and English vices enough in all conscience; and why not English Hedges, instead of post-and-rail and board fences? If, instead of these steril-looking and cheerless enclosures the gardens and meadows and fields, in the neighbourhood of New York and other cities and towns, were divided by quick-set hedges, what a difference would the alteration make in the look, and in the real value too, of those gardens, meadows and fields![30]

Regulation

In the US, some local jurisdictions may strictly regulate the placement or height of a hedge, such as the case where a Palo Alto city resident was arrested for allowing her xylosma hedge to grow above two feet.[31]

In the UK the owner of a large hedge that is adversely affecting the reasonable enjoyment of neighbouring domestic property can be made to reduce it in height. In England and Wales, high hedges are covered under Part 8 of the Anti-Social Behaviour Act 2003. For a hedge to qualify for reduction, it must be made up wholly or mainly of a line of two or more evergreen or semi-evergreen trees or shrubs and be over 2 metres high. To some degree, it must be a barrier to light or access. It must be adversely affecting the complainant's reasonable enjoyment of their domestic property (either their house or garden) because of its height.[19] Later legislation with similar effect was introduced in Northern Ireland, Isle of Man and Scotland.

Privet

Privet

A privet is a flowering plant in the genus Ligustrum. The genus contains about 50 species of erect, deciduous or evergreen shrubs, sometimes forming small or medium-sized trees, native to Europe, north Africa, Asia, many introduced and naturalised in Australasia, where only one species, Ligustrum australianum, extends as a native into Queensland. Some species have become widely naturalized or invasive where introduced. Privet was originally the name for the European semi-evergreen shrub Ligustrum vulgare, and later also for the more reliably evergreen Ligustrum ovalifolium and its hybrid Ligustrum × ibolium used extensively for privacy hedging, though now the name is applied to all members of the genus. The generic name was applied by Pliny the Elder to L. vulgare. It is often suggested that the name privet is related to private, but the OED states that there is no evidence to support this.

Crataegus

Crataegus

Crataegus, commonly called hawthorn, quickthorn, thornapple, May-tree, whitethorn, Mayflower, or hawberry, is a genus of several hundred species of shrubs and trees in the family Rosaceae, native to temperate regions of the Northern Hemisphere in Europe, Asia, North Africa, and North America. The name "hawthorn" was originally applied to the species native to northern Europe, especially the common hawthorn C. monogyna, and the unmodified name is often so used in Britain and Ireland. The name is now also applied to the entire genus and to the related Asian genus Rhaphiolepis.

Beech

Beech

Beech (Fagus) is a genus of deciduous trees in the family Fagaceae, native to temperate Europe, Asia, and North America. Recent classifications recognize 10 to 13 species in two distinct subgenera, Engleriana and Fagus. The Engleriana subgenus is found only in East Asia, distinctive for its low branches, often made up of several major trunks with yellowish bark. The better known Fagus subgenus beeches are high-branching with tall, stout trunks and smooth silver-grey bark. The European beech is the most commonly cultivated.

Berberis

Berberis

Berberis, commonly known as barberry, is a large genus of deciduous and evergreen shrubs from 1–5 m (3.3–16.4 ft) tall, found throughout temperate and subtropical regions of the world. Species diversity is greatest in South America and Asia; Europe, Africa and North America have native species as well. The best-known Berberis species is the European barberry, Berberis vulgaris, which is common in Europe, North Africa, the Middle East, and central Asia, and has been widely introduced in North America. Many of the species have spines on the shoots and all along the margins of the leaves.

Conifer

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. As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species.

Climate

Climate

Climate is the long-term weather pattern in a region, typically averaged over 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere and the interactions between them. The climate of a location is affected by its latitude, longitude, terrain, altitude, land use and nearby water bodies and their currents.

Ceanothus

Ceanothus

Ceanothus is a genus of about 50–60 species of nitrogen-fixing shrubs and small trees in the buckthorn family (Rhamnaceae). Common names for members of this genus are buckbrush, California lilac, soap bush, or just ceanothus. "Ceanothus" comes from Ancient Greek: κεάνωθος (keanōthos), which was applied by Theophrastus to an Old World plant believed to be Cirsium arvense.

The 19th-century Great Hedge of India was probably the largest example of a hedge used as a barrier. It was planted and used to collect taxes by the British.

The Willow Palisade, constructed during the early Qing dynasty (17th century) to control people's movement and to collect taxes on ginseng and timber in southern Manchuria, also had hedge-like features. The palisade included two dikes and a moat between them, the dikes topped by rows of willow trees, tied to one another with their branches.[32] Gradually decaying throughout the late 18th and 19th centuries, the palisade disappeared in the early 20th century, its remaining willows cut during the Russo-Japanese War of 1904–1905 by the two countries' soldiers.[33]

The Meikleour Beech Hedges, located near Meikleour in Scotland, are noted in the Guinness World Records as the tallest and longest hedge on earth, reaching 30 metres (98 ft) in height and 530 metres (0.33 mi) in length. The beech trees were planted in 1745 by Jean Mercer on the Marquess of Lansdowne's Meikleour estate.

The hedgerows and sunken lanes in Normandy, France posed a problem to Allied tanks after Operation Overlord, the invasion of Europe, in World War 2. The hedgerows prevented the tanks from freely moving about the area, until they were fitted with tusks.

Qing dynasty

Qing dynasty

The Qing dynasty, officially the Great Qing, was a Manchu-led imperial dynasty of China (1636–1912) and the last orthodox dynasty in Chinese history. It emerged from the Later Jin dynasty founded by the Jianzhou Jurchens, a Tungusic-speaking ethnic group who unified other Jurchen tribes to form a new "Manchu" ethnic identity. The dynasty was officially proclaimed in 1636 in Manchuria. It seized control of Beijing in 1644, then later expanded its rule over the whole of China proper and Taiwan, and finally expanded into Inner Asia. The dynasty lasted until 1912 when it was overthrown in the Xinhai Revolution. In orthodox Chinese historiography, the Qing dynasty was preceded by the Ming dynasty and succeeded by the Republic of China. The multiethnic Qing dynasty lasted for almost three centuries and assembled the territorial base for modern China. It was the largest imperial dynasty in the history of China and in 1790 the fourth-largest empire in world history in terms of territorial size. With 419,264,000 citizens in 1907, it was the most populous country in the world at the time.
