90-611: Forbury Gardens is a public park in the town of Reading in the English county of Berkshire . The park is on the site of the outer court of Reading Abbey , which was in front of the Abbey Church. The site was formerly known as the Forbury , and one of the roads flanking the current gardens is still known as The Forbury . Fairs were held on the site three times a year until the 19th century. The gardens are listed as Grade II in

180-451: A 10-minute walk , provides multiple benefits. A park is an area of open space provided for recreational use, usually owned and maintained by a local government. Grass is typically kept short to discourage insect pests and to allow for the enjoyment of picnics and sporting activities. Trees are chosen for their beauty and to provide shade , with an increasing emphasis on reducing an urban heat island effect. Some early parks include

270-465: A bed and reaching sexual maturity within a year. Oysters are filter feeders , drawing water in over their gills through the beating of cilia . Suspended plankton and non-food particles are trapped in the mucus of a gill, and from there are transported to the mouth, where they are eaten, digested, and expelled as feces or pseudofeces that fall to the bottom and remain out of the water column. Oysters feed most actively at temperatures ranging from

360-442: A distinct family, the feathered oysters ( Pteriidae ). Both cultured pearls and natural pearls can be extracted from pearl oysters, though other molluscs, such as the freshwater mussels , also yield pearls of commercial value. The largest pearl-bearing oyster is the marine Pinctada maxima , which is roughly the size of a dinner plate. Not all individual oysters produce pearls. In nature, pearl oysters produce pearls by covering

450-427: A mass stabbing in the gardens. The incident was treated as a terrorist incident ; its perpetrator was later sentenced to a whole-life term . After the attack, the gardens were closed to the public for three weeks to facilitate the police investigation. Following the reopening, flowers, originally laid by members of the public in various locations around the town, were moved to surround the garden's bandstand. In 2023,

540-419: A minute invasive object with nacre . Over the years, the irritating object is covered with enough layers of nacre to become a pearl. The many different types, colours and shapes of pearls depend on the natural pigment of the nacre, and the shape of the original irritant. Pearl farmers can culture a pearl by placing a nucleus, usually a piece of polished mussel shell, inside the oyster. In three to seven years,

630-541: A popular treat celebrated in oyster festivals in many cities and towns. It was once assumed that oysters were only safe to eat in months with the letter 'r' in their English and French names. This myth is based in truth, in that in the Northern Hemisphere, oysters are much more likely to spoil in the warmer months of May, June, July, and August. In recent years , pathogens such as Vibrio parahaemolyticus have caused outbreaks in several harvesting areas of

720-586: A refreshment kiosk, public toilets and facilities for a resident gardener. A grand re-opening event took place on 14 May 2005 to mark the completion of the project. In 2015, a statue was unveiled to the memory of Trooper Fred Potts VC , who was awarded the Victoria Cross in October 1915 after endangering his own life to drag a wounded comrade from the battlefield at the Battle of Scimitar Hill . The statue

810-483: A resting state, even when they are permanently submersed. Their behaviour follows very strict circatidal and circadian rhythms according to the relative moon and sun positions. During neap tides, they exhibit much longer closing periods than during the spring tide. Some tropical oysters, such as the mangrove oyster in the family Ostreidae , grow best on mangrove roots. Low tide can expose them, making them easy to collect. The largest oyster-producing body of water in

900-449: A result of global change are also negatively impacting oysters around the world, with many impacts affecting molecular, physiological, and behavioral processes in species including Magallana gigas. Recycled oyster shells can help restore oyster reefs to provide marine life habitat that reduces flooding, and protects shorelines from storms. Shell-recycling non-profits retrieve shells from restaurants, wash and dry them, and set them in

990-583: A site where pollution was affecting beach tourism. Currently, for the installation cost of $ 3000, roughly 4.8 million liters of water are being filtered daily. In New Jersey, however, the Department of Environmental Protection refused to allow oysters as a filtering system in Sandy Hook Bay and the Raritan Bay, citing worries that commercial shellfish growers would be at risk and that members of

1080-658: A small mound was erected in 1909, in memory of Henry I , on the north-west corner of the footings of the Abbey Church. The Verdun Oak was planted in July 1919 to commemorate the restoration of peace after the First World War . It is one of a number of Verdun trees in the United Kingdom which are grown from acorns and other seeds collected from the battlefield at Verdun . It lies between the Maiwand Lion and

1170-672: A summer house, and became known as the Pleasure Gardens. Work started in 1855 and the Pleasure Gardens opened on Easter Sunday 1856. A tunnel was built on the eastern side in 1859 to link the gardens and the Abbey ruins. The success of the Pleasure Gardens contrasted with the situation in the western part of the Forbury, which was still used for fairs. After one fair, the area was described as being covered 'with heaps of oyster shells, manure and other refuse'. In 1860, this section of

1260-468: A wall. However in 1869 the town purchased 12 acres (4.9 ha) of King's Meadow , the abbey's former water meadow by the River Thames , as a recreation ground. This paved the way for the incorporation, in 1873, of the western part of the Forbury into the gardens, which then became known as Forbury Gardens. The Maiwand Lion statue was erected in 1886 to commemorate the loss of 286 soldiers (though

1350-501: Is believed to be the last-built Connecticut oyster sloop, completed in 1948. Oysters can also be collected by divers . In any case, when the oysters are collected, they are sorted to eliminate dead animals, bycatch (unwanted catch), and debris. Then they are taken to market, where they are either canned or sold live. Oysters have been cultured since at least the days of the Roman Empire . The Pacific oyster ( Magallana gigas )

1440-436: Is dominated by the larger Pacific oyster and Rock oyster species which are farmed year-round. Oysters are harvested by simply gathering them from their beds. In very shallow waters, they can be gathered by hand or with small rakes . In somewhat deeper water, long-handled rakes or oyster tongs are used to reach the beds. Patent tongs can be lowered on a line to reach beds that are too deep to reach directly. In all cases,

1530-746: Is estimated that one acre (0.40 ha) can produce nearly 750,000 oysters, which could filter between 57,000 to 150,000 m (2.0–5.3 million cu ft) of water daily. Also see nutrient pollution for an extended explanation of nutrient remediation . As an ecosystem engineer , oysters provide supporting ecosystem services , along with provisioning, regulating and cultural services. Oysters influence nutrient cycling , water filtration , habitat structure, biodiversity , and food web dynamics. Oyster reef habitats have been recognized as green infrastructure for shoreline protection. Assimilation of nitrogen and phosphorus into shellfish tissues provides an opportunity to remove these nutrients from

1620-543: Is held in September. In fact, in Victorian England, it was quite common for people to go to the pub and enjoy their favorite beer with some oysters. They quickly realized that the "rich, sweet, malty stouts" were great with the "briny, creamy oyster". Then brewers found that oyster shells naturally clarify a beer and they started putting crushed oyster shells into their brews. The first known brewery to start this

1710-793: Is just outside the garden wall, facing the Crown Court building. In the same year, the Reading International Brigade Memorial was relocated from the Civic Centre to the east side of the gardens, and rededicated. This sculpture by Eric Stanford is a memorial to those lost in the Spanish Civil War and preparatory sketches are held by the University of Reading . On 20 June 2020, three people were killed and three others seriously injured in

1800-518: Is presently the most widely grown bivalve around the world. Two methods are commonly used, release and bagging. In both cases, oysters are cultivated onshore to the size of spat, when they can attach themselves to a substrate. They may be allowed to mature further to form "seed oysters". In either case, they are then placed in the water to mature. The release technique involves distributing the spat throughout existing oyster beds, allowing them to mature naturally to be collected like wild oysters. Bagging has

1890-409: Is technically possible for an oyster to fertilize its own eggs. The gonads surround the digestive organs, and are made up of sex cells, branching tubules, and connective tissue. Once her millions of eggs are fertilized, the female discharges them into the water. The larvae develop in about six hours and exist suspended in the water column as veliger larvae for two to three weeks before settling on

1980-444: Is the common name for a number of different families of salt-water bivalve molluscs that live in marine or brackish habitats. In some species, the valves are highly calcified , and many are somewhat irregular in shape. Many, but not all oysters, are in the superfamily Ostreoidea . Some species of oyster are commonly consumed and are regarded as a delicacy in some localities. Some types of pearl oysters are harvested for

In 2020, they were the site of a terrorist attack in which three people were killed and others injured . Forbury , a suburb of the New Zealand city of Dunedin , was named after the gardens by early resident William Henry Valpy , who was born in Reading. Reading Abbey was founded in 1121, by Henry I , and for

2160-562: The La Alameda de Hércules , in Seville , a promenaded public mall, urban garden and park built in 1574, within the historic center of Seville. The Városliget ( City Park ) in the City of Pest , what is today Budapest, Hungary , was a city property when afforestation started in the middle of the 18th century, from the 1790s with the clear aim to create a public park. Between 1799 and 1805 it

2250-476: The Philippines , a local thorny oyster species known as Tikod amo is a favorite seafood source in the southern part of the country. Because of its good flavor, it commands high prices. Oysters breathe primarily via gills . In addition to their gills, oysters can exchange gases across their mantles , which are lined with many small, thin-walled blood vessels . A small, three-chambered heart , lying under

2340-696: The United States is the Chesapeake Bay , although these beds have decreased in number due to overfishing and pollution. Other large oyster farming areas in the US include the bays and estuaries along the coast of the Gulf of Mexico from Apalachicola, Florida , in the east to Galveston, Texas , in the west. Large beds of edible oysters are also found in Japan and Australia. In 2005, China accounted for 80% of

2430-623: The Village of Yorkville Park in Toronto , which won an award from the American Society of Landscape Architects. Parks are sometimes made out of oddly shaped areas of land, much like the vacant lots that often become city neighborhood parks. Linked parks may form a greenbelt . There is a form of an urban park in the UK (officially called a "recreation ground", but commonly called a "rec" by

2520-469: The adductor muscle , pumps colorless blood to all parts of the body. At the same time, two kidneys , located on the underside of the muscle, remove waste products from the blood. Their nervous system includes two pairs of nerve cords and three pairs of ganglia . There is no evidence that oysters have a brain. While some oysters have two sexes ( European oyster and Olympia oyster ), their reproductive organs contain both eggs and sperm. Because of this, it

2610-587: The eastern oyster ( Crassostrea virginica ) was introduced to California waters in 1875, while the Pacific oyster was introduced there in 1929. Proposals for further such introductions remain controversial. The Pacific oyster prospered in Pendrell Sound , where the surface water is typically warm enough for spawning in the summer. Over the following years, spat spread out sporadically and populated adjacent areas. Eventually, possibly following adaptation to

2700-600: The pearl produced within the mantle . Others, such as the translucent Windowpane oysters , are harvested for their shells. The word oyster comes from Old French oistre , and first appeared in English during the 14th century. The French derived from the Latin ostrea , the feminine form of ostreum , which is the latinisation of the Ancient Greek ὄστρεον ( ostreon ) 'oyster'. Compare ὀστέον ( osteon ) 'bone'. True oysters are members of

2790-526: The tides . He was so famous for this, the Romans used to say he could breed oysters on the roof of his house. In the early 19th century, oysters were cheap and mainly eaten by the working class . Throughout the 19th century, oyster beds in New York Harbor became the largest source of oysters worldwide. On any day in the late 19th century, six million oysters could be found on barges tied up along

As a result of the concerns sparked in England by the French Revolution , and throughout the ensuing Napoleonic Wars , the Forbury was used for military drills and parades, in addition to its well-established use for fairs and circuses. Three annual fairs were generally held on the Forbury, but

2970-412: The Forbury was purchased by the town for £6010 from Colonel Blagrave. It was decided that fairs should no longer be held there, but the emphasis remained on recreational use rather than botanical display, with the area grassed except for the outside walks and a gravelled parade ground. The common ownership notwithstanding, the two halves of the Forbury remained very different in character, and separated by

3060-615: The Forbury. Reading suffered badly during the English Civil War , being occupied at different times by both sides. During the Siege of Reading (1642–43), the Royalist garrison built defences that further damaged the remains of the Abbey, and Forbury Hill was used as a gun emplacement. The origins of Forbury Hill are uncertain, but core samples taken in 2017 by the University of Reading have shown that it cannot be earlier than

The borough of Colchester holds an annual Oyster Feast each October, at which "Colchester Natives" (the native oyster, Ostrea edulis ) are consumed. The United Kingdom hosts several other annual oyster festivals; for example, Woburn Oyster Festival

3330-522: The United States and the world, though cow grazing did not end until the 1830s. Around the country, the predecessors to urban parks in the United States were generally rural cemeteries . The cemeteries were intended as civic institutions designed for public use. Before the widespread development of public parks, the rural cemetery provided a place for the general public to enjoy outdoor recreation amidst art and sculpture previously available only for

3420-842: The United States are Central Park in New York, Lincoln Park in Chicago, Mission Bay Park in San Diego. In the early 1900s, according to Cranz, U.S. cities built neighborhood parks with swimming pools, playgrounds and civic buildings, with the intention of Americanizing the immigrant residents. In the 1950s, when money became available after World War II , new parks continued to focus on both outdoor and indoor recreation with services, such as sports leagues using their ball fields and gymnasia. These smaller parks were built in residential neighborhoods, and tried to serve all residents with programs for seniors, adults, teens and children. Green space

3780-435: The beds by the early 20th century. Oysters' popularity has put ever-increasing demands on wild oyster stocks. This scarcity increased prices, converting them from their original role as working-class food to their current status as an expensive delicacy. In Britain, the native species ( European flat oyster ) has five years to mature and is protected by the people during their May-to-August spawning season. The current market

In the U.S., Delaware is the only East Coast state without aquaculture, but making aquaculture a state-controlled industry of leasing water by the acre for commercial harvesting of shellfish is being considered. Supporters of Delaware's legislation to allow oyster aquaculture cite revenue, job creation, and nutrient cycling benefits. It

New York's oystermen became skilled cultivators of their beds, which provided employment for hundreds of workers and nutritious food for thousands. Eventually, rising demand exhausted many of the beds. To increase production, they introduced foreign species, which brought disease; effluent and increasing sedimentation from erosion destroyed most of

4050-481: The community. The Forbury Hill is now accessible by two winding footpaths (wheelchair-accessible) that lead to an area that is elevated about 3 metres (9.8 ft) above the surrounding gardens. A single plane tree stands in the middle, and around the outer edge of the top of the hill are wooden seats. A short tunnel in the south-east corner of the gardens provides traffic free access to the ruins of Reading Abbey . Reading Borough Council organises summer concerts in

The latter commenced in 1843 with the help of public finance and deployed the ideas which Paxton had pioneered at Princes Park on a more expansive scale. Frederick Law Olmsted visited Birkenhead Park in 1850 and praised its qualities. Indeed, Paxton is widely credited as having been one of

4230-549: The cultivator putting spat in racks or bags and keeping them above the bottom. Harvesting involves simply lifting the bags or rack to the surface and removing the mature oysters. The latter method prevents losses to some predators, but is more expensive. The Pacific oyster has been grown in the outflow of mariculture ponds. When fish or prawns are grown in ponds, it takes typically 10 kg (22 lb) of feed to produce 1 kg ( 2 + 1 ⁄ 4  lb) of product ( dry-dry basis). The other 9 kg (20 lb) goes into

Examples include the European flat oyster , eastern oyster , Olympia oyster , Pacific oyster , and the Sydney rock oyster . Ostreidae evolved in the Early Triassic epoch : The genus Liostrea grew on the shells of living ammonoids . Almost all shell-bearing mollusks can secrete pearls, yet most are not very valuable. Pearls can form in both saltwater and freshwater environments. Pearl oysters are not closely related to true oysters, being members of

4770-779: The form of walking, running, horse riding, mountain biking, snowshoeing, or cross-country skiing; or sedentary activity such as observing nature, bird watching, painting, photography, or picnicking. Limiting park or open space use to passive recreation over all or a portion of the park's area eliminates or reduces the burden of managing active recreation facilities and developed infrastructure. Many ski resorts combine active recreation facilities (ski lifts, gondolas, terrain parks, downhill runs, and lodges) with passive recreation facilities (cross-country ski trails). Many smaller neighborhood parks are receiving increased attention and valuation as significant community assets and places of refuge in heavily populated urban areas. Neighborhood groups around

4860-406: The garden's bandstand underwent a significant refurbishment, with the structure being conserved and repainted in the original colours of white and green and the previously grassed slopes around the podium replaced with cobbles . The cobbled structure incorporates a memorial to the victims of the 2020 attack, which was unveiled during a memorial service on 20 June 2023, marking the third anniversary of

4950-486: The gardens underwent a one-year restoration project. The Heritage Lottery Fund awarded Reading Borough Council £2.13 million to restore the historic features of the Forbury Gardens and improve safety and access for visitors. Work in the gardens included the restoration of the Maiwand Lion, the bandstand, water feature and the garden's walls, fencing and gateways. A new Keeper's Lodge was also constructed, including

5040-412: The global oyster harvest. In Europe, France remained the industry leader. Common oyster predators include crabs , seabirds , starfish , and humans . Some oysters contain crabs, known as oyster crabs . Bivalves , including oysters, are effective filter feeders and can have large effects on the water columns in which they occur. As filter feeders, oysters remove plankton and organic particles from

Under average conditions, mature oysters filter 11–45 L (3–12 U.S. gal). Chesapeake Bay 's once-flourishing oyster population historically filtered excess nutrients from the estuary's entire water volume every three to four days. As of 2008 it

5220-525: The large amount of open space and natural habitat in the former pleasure grounds, they now serve as important wildlife refuges, and often provide the only opportunity for urban residents to hike or picnic in a semi-wild area. However, city managers or politicians can target these parks as sources of free land for other uses. Partly for this reason, some of these large parks have "friends of X park" advisory boards that help protect and maintain their semi-wild nature. There are around estimated 27,000 public parks in

5310-521: The late 1880s, when the bay's population was in the billions, and watermen harvested about 910,000 m (25 million imp bsh) annually. The 2009 harvest was less than 7,300 m (200,000 imp bsh). Researchers claim the keys to the project were: The "oyster-tecture" movement promotes the use of oyster reefs for water purification and wave attenuation. An oyster-tecture project has been implemented at Withers Estuary, Withers Swash, South Carolina, by Neil Chambers-led volunteers, at

Pendrell Sound is now a reserve that supplies spat for cultivation. Near the mouth of the Great Wicomico River in the Chesapeake Bay , five-year-old artificial reefs now harbor more than 180 million native Crassostrea virginica . That is far lower than in

5490-666: The loss of half of California's Olympia oysters . Oyster reefs occupy a small fraction of their distribution prior to mass harvesting during the last three centuries. In October 2017, it was reported that underwater noise pollution can affect oysters as they close their shells when exposed to low frequencies of sounds in experimental conditions. Oysters rely on hearing waves and currents to regulate their circadian rhythms , and perception of weather events—such as rain —may induce spawning . Cargo ships , pile drivers , and explosions conducted underwater produce low frequencies that may be detected by oysters. Environmental stressors as

This fair became known as the Reading Cheese Fair , although cattle, horses and hops were also sold, and it served as the principal local hiring fair . By the first years of the 19th century, the western part of the Forbury was in use as a playground or sports ground for Reading School , which at this time was housed in the former Hospitium of St John . However

Passive recreation, also called "low-intensity recreation" is that which emphasizes the open-space aspect of a park and allows for the preservation of natural habitat. It usually involves a low level of development, such as rustic picnic areas, benches, and trails. Passive recreation typically requires little management and can be provided at very low costs. Some open space managers provide nothing other than trails for physical activity in

Like other such monasteries, Reading had a forbury , or 'borough in front', an area of open land which provided a meeting place between the Abbey and the town. The Forbury in Reading was part of the outer court of the Abbey, and provided a market place as well as a meeting place. The abbey

An increase in water temperature prompts a few oysters to spawn. This triggers spawning in the rest, clouding the water with millions of eggs and sperm. A single female oyster can produce up to 100 million eggs annually. The eggs become fertilized in

5940-489: The oyster can produce a perfect pearl. Since the beginning of the 20th century, when several researchers discovered how to produce artificial pearls, the cultured pearl market has far outgrown the natural pearl market. A number of bivalve molluscs (other than true oysters and pearl oysters) also have common names that include the word "oyster", usually because they either taste like or look somewhat like true oysters, or because they yield noticeable pearls. Examples include: In

The creation of Princes Park showed great foresight and introduced a number of highly influential ideas. First and foremost was the provision of open space for the benefit of townspeople and local residents within an area that was being rapidly built up. Secondly it took the concept of

6120-420: The past three years and 95 per cent expect their funding will continue to reduce". Parks can be divided into active and passive recreation areas. Active recreation is that which has an urban character and requires intensive development. It often involves cooperative or team activity, including playgrounds , ball fields, swimming pools, gymnasiums, and skateparks . Active recreation such as team sports, due to

6210-463: The pond and after mineralization, provides food for phytoplankton, which in turn feeds the oyster. To prevent spawning, sterile oysters are now cultured by crossbreeding tetraploid and diploid oysters. The resulting triploid oyster cannot propagate, which prevents introduced oysters from spreading into unwanted habitats. In many areas, non-native oysters have been introduced in attempts to prop up failing harvests of native varieties. For example,

Boston Common was purchased for public use grazing cows and as a military parade ground and dump in 1634. It first started to get recreational elements in 1728, arguably making it the first municipal park in

Jonathan Swift is quoted as having said, "He was a bold man that first ate an oyster". Evidence of oyster consumption goes back into prehistory, evidenced by oyster middens found worldwide. Oysters were an important food source in all coastal areas where they could be found, and oyster fisheries were an important industry where they were plentiful. Overfishing and pressure from diseases and pollution have sharply reduced supplies, but they remain

6660-424: The surface area of a flat bottom 50-fold. An oyster's mature shape often depends on the type of bottom to which it is originally attached, but it always orients itself with its outer, flared shell tilted upward. One valve is cupped and the other is flat. Oysters usually reach maturity in one year. They are protandric ; during their first year, they spawn as males by releasing sperm into the water. As they grow over

6750-529: The task is the same: the oysterman scrapes oysters into a pile, and then scoops them up with the rake or tongs. In some areas, a scallop dredge is used. This is a toothed bar attached to a chain bag. The dredge is towed through an oyster bed by a boat, picking up the oysters in its path. While dredges collect oysters more quickly, they heavily damage the beds, and their use is highly restricted. Until 1965, Maryland limited dredging to sailboats , and even since then motor boats can be used only on certain days of

6840-484: The threat of rising sea levels due to climate change . Additionally Oyster reef restoration has shown to increase the population of oyster beds within the oceans while also conserving the biolife within the oyster reefs. The accidental or intentional introduction of species by humans has the potential to negatively impact native oyster populations. For example, non-native species in Tomales Bay have resulted in

6930-503: The water and develop into larvae, which eventually find suitable sites, such as another oyster's shell, on which to settle. Attached oyster larvae are called spat. Spat are oysters less than 25 mm (1 in) long. Many species of bivalves, oysters included, seem to be stimulated to settle near adult conspecifics . Oysters filter large amounts of water to feed and breathe (exchange O 2 and CO 2 with water) but they are not permanently open. They regularly shut their valves to enter

7020-548: The water column. In California's Tomales Bay , native oyster presence is associated with higher species diversity of benthic invertebrates. As the ecological and economic importance of oyster reefs has become more acknowledged, restoration efforts have increased. Middens testify to the prehistoric importance of oysters as food, with some middens in New South Wales , Australia, dated at ten thousand years. They have been cultivated in Japan from at least 2000 BC. In

7110-416: The water column. Multiple studies have shown individual oysters are capable of filtering up to 190 litres (42 imp gal; 50 US gal) of water per day, and thus oyster reefs can significantly improve water quality and clarity. Oysters consume nitrogen-containing compounds ( nitrates and ammonia ), phosphates , plankton, detritus, bacteria, and dissolved organic matter, removing them from

7200-490: The water. What is not used for animal growth is then expelled as solid waste pellets, which eventually decompose into the atmosphere as nitrogen. In Maryland , the Chesapeake Bay Program had implemented a plan to use oysters to reduce the amount of nitrogen compounds entering the Chesapeake Bay by 8,600 t (9,500 short tons) per year by 2010. Several studies have shown that oysters and mussels have

7290-490: The wealthy. In The Politics of Park Design: A History of Urban Parks in America, (Cambridge, Massachusetts: MIT Press, 1982), Professor Galen Cranz identifies four phases of park design in the U.S. In the late 19th century, city governments purchased large tracts of land on the outskirts of cities to form "pleasure grounds": semi-open, charmingly landscaped areas whose primary purpose was to allow city residents, especially

7380-480: The week. These regulations prompted the development of specialized sailboats (the bugeye and later the skipjack ) for dredging. Similar laws were enacted in Connecticut before World War I and lasted until 1969. The laws restricted the harvesting of oysters in state-owned beds to vessels under sail. These laws prompted the construction of the oyster sloop-style vessel to last well into the 20th century. Hope

7470-411: The whole of the Forbury was in private ownership, and disputes were common as to the common rights of the town and the rights of the school. In 1854, Forbury Hill and the eastern section of the present gardens were sold to Reading Corporation at the cost of £ 1200, of which £400 was donated by the previous owner, a Mr Wheble. The resulting gardens were planned with a 'botanical character', a fountain and

7560-488: The workers, to relax in nature. As time passed and the urban area grew around the parks, land in these parks was used for other purposes, such as zoos, golf courses and museums. These parks continue to draw visitors from around the region and are considered regional parks , because they require a higher level of management than smaller local parks. According to the Trust for Public Land , the three most visited municipal parks in

7650-531: The world are joining together to support local parks that have suffered from urban decay and government neglect. A linear park is a park that has a much greater length than width. A typical example of a linear park is a section of a former railway that has been converted into a park called a rail trail or greenway (i.e. the tracks removed, vegetation allowed to grow back). Some examples of linear parks in North America include New York's High Line and

7740-679: Was estimated that a complete cycle would take nearly a year. A group of oysters is commonly called a bed or oyster reef . As a keystone species , oysters provide habitat for many marine species. Crassostrea and Saccostrea live mainly in the intertidal zone , while Ostrea is subtidal . The hard surfaces of oyster shells and the nooks between the shells provide places where a host of small animals can live. Hundreds of animals, such as sea anemones , barnacles , and hooked mussels , inhabit oyster reefs . Many of these animals are prey to larger animals, including fish, such as striped bass , black drum and croakers . An oyster reef can increase

7830-698: Was in 1938 at the Hammerton Brewery in London. That is where the oyster stout was first started. The French seaside resort of Cancale in Brittany is noted for its oysters, which also date from Roman times. Sergius Orata of the Roman Republic is considered the first major merchant and cultivator of oysters. Using his considerable knowledge of hydraulics , he built a sophisticated cultivation system, including channels and locks, to control

7920-461: Was largely destroyed in 1538 during Henry VIII 's Dissolution of the Monasteries . The last abbot, Hugh Cook Faringdon , was tried and convicted of high treason , and hanged, drawn and quartered in front of the Abbey Church. After this, the buildings of the abbey were extensively looted, with lead, glass and facing stones removed for reuse elsewhere, and the focus of the town moved away from

8010-530: Was of secondary importance. As urban land prices climbed, new urban parks in the 1960s and after have been mainly pocket parks . One example of a pocket park is Chess Park in Glendale, California. The American Society of Landscape Architects gave this park a General Design Award of Honor in 2006. These small parks provide greenery, a place to sit outdoors, and often a playground for children. All four types of park continue to exist in urban areas. Because of

8100-547: Was rented out to the Batthyány family to carry out such a project but the city had eventually taken back control and in 1813 announced a design competition to finally finish the park; works started in 1816. An early purpose-built public park, although financed privately, was Princes Park in the Liverpool suburb of Toxteth . This was laid out to the designs of Joseph Paxton from 1842 and opened in 1843. The land on which
