81-540: Western Sydney Regional Park is a large urban park and a nature reserve situated in Western Sydney , Australia within the suburbs of Horsley Park and Abbotsbury . A precinct of Western Sydney Parklands , and situated within the heart of the Cumberland Plain Woodland , the regional park features several picnic areas, recreational facilities, equestrian trails, and walking paths within

162-451: 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

243-418: A forest dynamics perspective, old-growth forest is in a stage that follows understory reinitiation stage. Those stages are: Of importance is that while the stand switches from one tree community to another, the stand will not necessarily go through old-growth stage between those stages. Some tree species have a relatively open canopy. That allows more shade-tolerant tree species to establish below even before

324-432: A biodiversity that is different from other forest stages. The characteristic topography of much old-growth forest consists of pits and mounds. Mounds are caused by decaying fallen trees, and pits ( tree throws ) by the roots pulled out of the ground when trees fall due to natural causes, including being pushed over by animals. Pits expose humus -poor, mineral-rich soil and often collect moisture and fallen leaves, forming

405-562: A broad system of walking and cycling opportunities on various tracks which link the several fundamental recreational areas. The park also features the Sydney International Equestrian Centre , which was built for the 2000 Olympic Games . The park's main recreational points include Pimelea, Sugarloaf Ridge, The Dairy and Plough and Harrow picnic areas, all of which have shelters, playgrounds and free barbeques, in addition to large parking spaces. There exists

486-577: A different potential to store carbon. For example, this potential is particularly high in the Pacific Northwest where forests are relatively productive, trees live a long time, decomposition is relatively slow, and fires are infrequent. The differences between forests must, therefore, be taken into consideration when determining how they should be managed to store carbon. A 2019 study projected that old-growth forests in Southeast Asia ,

567-767: A different spatial location relative to the main canopy, hence each one receives a different amount of light. The mixed age of the forest is an important criterion in ensuring that the forest is a relatively stable ecosystem in the long term. A climax stand that is uniformly aged becomes senescent and degrades within a relatively short time to result in a new cycle of forest succession . Thus, uniformly aged stands are less stable ecosystems. Boreal forests are more uniformly aged, as they are normally subject to frequent stand-replacing wildfires. Forest canopy gaps are essential in creating and maintaining mixed-age stands. Also, some herbaceous plants only become established in canopy openings, but persist beneath an understory. Openings are

648-563: A healthy fungal ecosystem, and presence of indicator species. Old-growth forests are often biologically diverse , and home to many rare species , threatened species , and endangered species of plants and animals, such as the northern spotted owl , marbled murrelet and fisher , making them ecologically significant. Levels of biodiversity may be higher or lower in old-growth forests compared to that in second-growth forests, depending on specific circumstances, environmental variables, and geographic variables. Logging in old-growth forests

729-410: A moist, relatively mild climate, some old-growth trees have attained notable height and girth (DBH: diameter at breast height), accompanied by notable biodiversity in terms of the species supported. Therefore, for most people, the physical size of the trees is the most recognized hallmark of old-growth forests, even though the ecologically productive areas that support such large trees often comprise only

810-583: A part of the Upper Canal System (by Sydney Water ), which was constructed in the late 1800's. Bonnyrigg Reservoir is situated at the southern point of the park. Western Sydney Regional Park features around 135 hectares of developed natural woodland communities where the bulk of the regional park constitutes 427 hectares of planted revegetation and cleared grassland environments, thus providing multifarious habitat areas for wildlife and vegetation communities. Four vegetation zones are known within

891-704: A result of industrial logging operations. In 2006, about 61,000 hectares of tall-eucalypt RFA old-growth forests remained unprotected. Recent logging attempts in the Upper Florentine Valley have sparked a series of protests and media attention over the arrests that have taken place in this area. Additionally, Gunns Limited , the primary forestry contractor in Tasmania, has been under recent criticism by political and environmental groups over its practice of woodchipping timber harvested from old-growth forests. Increased understanding of forest dynamics in

972-550: A result of tree death due to small impact disturbances such as wind, low-intensity fires, and tree diseases. Old-growth forests are unique, usually having multiple horizontal layers of vegetation representing a variety of tree species , age classes, and sizes, as well as "pit and mound" soil shape with well-established fungal nets . As old-growth forest is structurally diverse, it provides higher-diversity habitat than forests in other stages. Thus, sometimes higher biological diversity can be sustained in old-growth forests, or at least

1053-432: A severe disturbance, such as wildfire, insect infestation, or harvesting, is often called second-growth or 'regeneration' until enough time passes for the effects of the disturbance to be no longer evident. Depending on the forest, this may take from a century to several millennia. Hardwood forests of the eastern United States can develop old-growth characteristics in 150–500 years. In British Columbia , Canada, old growth

1134-486: A source of raw materials. These services include making breathable air, making pure water, carbon storage, regeneration of nutrients, maintenance of soils, pest control by insectivorous bats and insects, micro- and macro-climate control, and the storage of a wide variety of genes. The effects of old-growth forests in relation to global warming have been addressed in various studies and journals. The Intergovernmental Panel on Climate Change said in its 2007 report : "In

1215-412: A substrate for seedling trees. Intact soils harbor many life forms that rely on them. Intact soils generally have very well-defined horizons, or soil profiles . Different organisms may need certain well-defined soil horizons to live, while many trees need well-structured soils free of disturbance to thrive. Some herbaceous plants in northern hardwood forests must have thick duff layers (which are part of

1296-400: A thick organic layer that is able to nurture certain types of organisms. Mounds provide a place free of leaf inundation and saturation, where other types of organisms thrive. Standing snags provide food sources and habitat for many types of organisms. In particular, many species of dead-wood predators, such as woodpeckers , must have standing snags available for feeding. In North America,

1377-417: A useful number to measure. So, some forests may be excluded from being categorized as old-growth even if they have old-growth attributes just because they are too young. Also, older forests can lack some old-growth attributes and be categorized as old-growth just because they are so old. The idea of using age is also problematic, because human activities can influence the forest in varied ways. For example, after

1458-584: A very small portion of the total area that has been mapped as old-growth forest. (In high-altitude, harsh climates, trees grow very slowly and thus remain at a small size. Such trees also qualify as old growth in terms of how they are mapped, but are rarely recognized by the general public as such.) The debate over old-growth definitions has been inextricably linked with a complex range of social perceptions about wilderness preservation, biodiversity, aesthetics, and spirituality, as well as economic or industrial values. In logging terms, old-growth stands are past

1539-1048: A walking track called the Spotted Gum Trail , which is 3 km in length, that loops around Plough and Harrow within the native bushland, thereby allowing walkers to encounter kangaroos and wallabies, in addition to birdwatching . Every entrance to the recreation spots contains prominent planting accompanied by a large signage to indicate access. Access to the park is through Cowpasture Road, Elizabeth Drive and The Horsley Drive . Recreational areas and facilities include: The regional park features five walking loops, which all have trail grades : Urban park Depending on size, budget, and land features, which varies considerably among individual parks, common features include playgrounds , gardens , hiking, running, fitness trails or paths, bridle paths , sports fields and courts, public restrooms, boat ramps, performance venues, or BBQ and picnic facilities. Park advocates claim that having parks near urban residents, including within

1620-511: Is a forest that has developed over a long period of time without disturbance . Due to this, old-growth forests exhibit unique ecological features. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. One-third (34 percent) of

1701-414: Is a contentious issue in many parts of the world. Excessive logging reduces biodiversity, affecting not only the old-growth forest itself, but also indigenous species that rely upon old-growth forest habitat. Some forests in the old-growth stage have a mix of tree ages, due to a distinct regeneration pattern for this stage. New trees regenerate at different times from each other, because each of them has

1782-669: Is affected. Climate change showed an impact on the mortality of some dominant tree species, as observed in the Korean pine . Climate change also showed an effect on the composition of species when forests were surveyed over a 10- and 20-year period, which may disrupt the overall productivity of the forest. According to the World Resources Institute , as of January 2009, only 21% of the original old-growth forests that once existed on Earth are remaining. An estimated one-half of Western Europe's forests were cleared before

1863-615: Is defined as 120 to 140 years of age in the interior of the province where fire is a frequent and natural occurrence. In British Columbia's coastal rainforests , old growth is defined as trees more than 250 years, with some trees reaching more than 1,000 years of age. In Australia, eucalypt trees rarely exceed 350 years of age due to frequent fire disturbance. Forest types have very different development patterns, natural disturbances and appearances. A Douglas-fir stand may grow for centuries without disturbance while an old-growth ponderosa pine forest requires frequent surface fires to reduce

1944-433: Is more accurate in forests where the species that constitute old-growth have long lifespans and succession is slow. Common cultural definitions and common denominators regarding what comprises old-growth forest, and the variables that define, constitute and embody old-growth forests include: Additionally, in mountainous, temperate landscapes (such as Western North America), and specifically in areas of high-quality soil and

2025-919: Is not the most commercially viable timber—in British Columbia, Canada, harvesting in the coastal region is moving to younger second-growth stands. A 2001 scientific symposium in Canada found that defining old growth in a scientifically meaningful, yet policy-relevant, manner presents some basic difficulties, especially if a simple, unambiguous, and rigorous scientific definition is sought. Symposium participants identified some attributes of late-successional, temperate-zone, old-growth forest types that could be considered in developing an index of "old-growthness" and for defining old-growth forests: Structural features: Compositional features: Process features: Old-growth forests provide ecosystem services that may be far more important to society than their use as

2106-411: Is particularly used for family picnics , walking, jogging , cycling , fitness and for its natural environment. Western Sydney Regional Park contains Calmsley Hill Farm, which is protected under State Heritage listing. The park is visited by school students for cross-country , sports and for environmental education. Other visitors include disabled groups, childcare and mothers groups. The park features

2187-557: Is seen as extremely economically unproductive, as timber can only be collected from falling trees, and also potentially damaging to nearby managed groves by creating environments conducive to root rot. It may be more productive to cut the old growth down and replace the forest with a younger one. The island of Tasmania , just off the southeast coast of Australia, has the largest amount of temperate old-growth rainforest reserves in Australia with around 1,239,000 hectares in total. While

2268-802: The Australian bush . The park is governed by the NSW National Parks and Wildlife Service and is listed under the National Parks and Wildlife Act 1974 . In a 2009–10 survey, the park had attracted approximately 430,000 visitors per annum. The Parkland was an area of specialty for the Darug people and it is still deemed as important by the Aboriginal Land Council . The Parkland has been visited by some early settlers , such as Edward Abbott and George Johnson. The Park

2349-562: 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

2430-486: The Middle Ages , and 90% of the old-growth forests that existed in the contiguous United States in the 1600s have been cleared. The large trees in old-growth forests are economically valuable, and have been subject to aggressive logging throughout the world. This has led to many conflicts between logging companies and environmental groups . From certain forestry perspectives, fully maintaining an old-growth forest

2511-717: The Regional Forest Agreement (RFA) attempted to prevent the clearfelling of defined "old-growth forests". This led to struggles over what constitutes "old growth". For example, in Western Australia, the timber industry tried to limit the area of old growth in the karri forests of the Southern Forests Region; this led to the creation of the Western Australian Forests Alliance , the splitting of

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

2673-597: The ecosystem services they provide. This can be a point of contention when some in the logging industry desire to harvest valuable timber from the forests, destroying the forests in the process, to generate short-term profits, while environmentalists seek to preserve the forests in their pristine state for benefits such as water purification , flood control , weather stability, maintenance of biodiversity, and nutrient cycling . Moreover, old-growth forests are more efficient at sequestering carbon than newly planted forests and fast-growing timber plantations , thus preserving

2754-535: The spotted owl is well known for needing standing snags for nesting habitat. Fallen timber, or coarse woody debris , contributes carbon -rich organic matter directly to the soil , providing a substrate for mosses , fungi, and seedlings , and creating microhabitats by creating relief on the forest floor. In some ecosystems such as the temperate rain forest of the North American Pacific coast , fallen timber may become nurse logs , providing

A small proportion of old-growth forests also exist in South-West Australia and are protected by federal laws from logging, which has not occurred there for more than 20 years. In British Columbia , Canada , old-growth forests must be maintained in each of

Most public parks have been provided and run by local authorities over the past hundred and seventy years, but these authorities have no statutory duty to fund or maintain these public parks. In 2016 the Heritage Lottery Fund 's State of UK Public Parks reported that "92 per cent of park managers report their maintenance budgets have reduced in

2997-522: 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

3078-842: 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

The regional park is bounded by Westlink M7 to the west in Cecil Park , The Horsley Drive to the north in Horsley Park , Cowpasture Drive to the east in Bossley Park and Elizabeth Drive to the south near Cecil Hills . There exists market gardens in the north, residential piece of land to the east and south, and agricultural residential and rural industrial properties to

Proponents of harvesting the forest argue the carbon stored in wood is available for use as biomass energy (displacing fossil fuel use), although using biomass as a fuel produces air pollution in the form of carbon monoxide , nitrogen oxides , volatile organic compounds , particulates, and other pollutants, in some cases at levels above those from traditional fuel sources such as coal or natural gas. Each forest has

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

With

3483-421: The economic optimum for harvesting—usually between 80 and 150 years, depending on the species. Old-growth forests were often given harvesting priority because they had the most commercially valuable timber, they were considered to be at greater risk of deterioration through root rot or insect infestation, and they occupied land that could be used for more productive second-growth stands. In some regions, old growth

Liverpool had a burgeoning presence in global maritime trade before 1800, and during the Victorian era its wealth rivalled that of London itself. The form and layout of Paxton's ornamental grounds, structured about an informal lake within

3645-436: The forest will switch back to understory reinitiation stage. Using the stand dynamics definition, old-growth can be easily evaluated using structural attributes. However, in some forest ecosystems, this can lead to decisions regarding the preservation of unique stands or attributes that will disappear over the next few decades because of natural succession processes. Consequently, using stand dynamics to define old-growth forests

3726-472: The forests is vital to climate change mitigation . Old-growth forests tend to have large trees and standing dead trees, multilayered canopies with gaps that result from the deaths of individual trees, and coarse woody debris on the forest floor. The trees of old-growth forests develop distinctive attributes not seen in younger trees, such as more complex structures and deeply fissured bark that can harbor rare lichens and mosses. A forest regenerated after

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

This coarse filter approach to biodiversity conservation recognizes ecological processes and provides for a dynamic distribution of old growth across the landscape. And all seral stages—young, medium, and old—support forest biodiversity. Plants and animals rely on different forest ecosystem stages to meet their habitat needs. In Australia ,

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

4050-525: The late 20th century led the scientific community to identify a need to inventory, understand, manage, and conserve representative examples of old-growth forests with their associated characteristics and values. Literature around old growth and its management is inconclusive about the best way to characterize the true essence of an old-growth stand. A better understanding of natural systems has resulted in new ideas about forest management, such as managed natural disturbances, which should be designed to achieve

4131-620: The local Regional Forest Agreement (RFA) was originally designed to protect much of this natural wealth, many of the RFA old-growth forests protected in Tasmania consist of trees of little use to the timber industry. RFA old-growth and high conservation value forests that contain species highly desirable to the forestry industry have been poorly preserved. Only 22% of Tasmania's original tall-eucalypt forests managed by Forestry Tasmania have been reserved. Ten thousand hectares of tall-eucalypt RFA old-growth forest have been lost since 1996, predominantly as

Although depending on the species logged, the forest that comes back after a 30% harvest may consist of proportionately fewer hardwood trees than a forest logged at 80% in which the light competition by less important tree species does not inhibit the regrowth of vital hardwoods. From

Old-growth forests have the potential to impact climate change, but climate change is also impacting old-growth forests. As the effects of global warming grow more substantial, the ability of old-growth forests to sequester carbon

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

In the boreal forest of Canada , catastrophic disturbances like wildfires minimize opportunities for major accumulations of dead and downed woody material and other structural legacies associated with old growth conditions. Typical characteristics of old-growth forest include the presence of older trees, minimal signs of human disturbance, mixed-age stands, presence of canopy openings due to tree falls, pit-and-mound topography , down wood in various stages of decay, standing snags (dead trees), multilayered canopies, intact soils ,

5508-462: The soil has shown old-growth forests are more productive at storing carbon than younger forests. Forest harvesting has little or no effect on the amount of carbon stored in the soil, but other research suggests older forests that have trees of many ages, multiple layers, and little disturbance have the highest capacities for carbon storage. As trees grow, they remove carbon from the atmosphere, and protecting these pools of carbon prevents emissions into

5589-516: The soil profile). Fungal ecosystems are essential for efficient in-situ recycling of nutrients back into the entire ecosystem. Stand age can also be used to categorize a forest as old-growth. For any given geographical area, the average time since disturbance until a forest reaches the old growth stage can be determined. This method is useful, because it allows quick and objective determination of forest stage. However, this definition does not provide an explanation of forest function. It just gives

5670-549: The understory reinitiation stage. The shade-tolerant trees eventually outcompete the main canopy trees in stem-exclusion stage. Therefore, the dominant tree species will change, but the forest will still be in stem-exclusion stage until the shade-tolerant species reach old-growth stage. Tree species succession may change tree species' composition once the old-growth stage has been achieved. For example, an old boreal forest may contain some large aspen trees, which may die and be replaced by smaller balsam fir or black spruce. Consequently,

5751-490: 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

5832-410: The west of it, with the elevation reaching 140 metres (460 ft) at its highest point. Eastern Creek flows southwards at the park's northern end and Ropes Creek flows in the west. The park also features small ponds and wetlands which are a refuge for the native wildlife. Furthermore, two radio telecommunication towers are situated in the regional park on Border Road. The regional park features

5913-668: The west. The regional park is situated within the Fairfield local government area, the Hawkesbury - Nepean and Georges Rivers catchment areas and the Deerubbin Local Aboriginal Land Council’s area. The park is mainly a savanna (i.e. grassy woodland), though it grades into a dry sclerophyll woodland in the southern portion. Located in the Sydney Basin , the park features three types of soils;

5994-488: 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

6075-531: 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

6156-471: The world has 1.11  billion   ha (2.7 billion acres) of primary forest remaining. Combined, three countries (Brazil, Canada, and Russia) host more than half (61 percent) of the world's primary forest. The area of primary forest has decreased by 81 million ha (200 million acres) since 1990, but the rate of loss more than halved in 2010–2020 compared with the previous decade. Old-growth forests are valuable for economic reasons and for

6237-500: The world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitats that increases the biodiversity of the forested ecosystem . Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree heights and diameters, and diverse tree species and classes and sizes of woody debris. As of 2020 ,

6399-530: 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

6480-472: Was originally used for agricultural purposes which included gardening , dairy farming and grazing . Prominent early settlers such as Edward Abbott and George Johnson have been associated with the park. The original homestead of Abbotsbury is located within the park, and is leased by the Sydney International Equestrian Centre . In the late 1970s, the northern parts of the regional park had areas for rural residential lots (near Horsley Park ), though by 1997

6561-547: 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
