The turfgrass in landscape and landscaping

Turfgrasses have become an essential element in the world landscape, due to their aesthetic, environmental and agricultural values. Since prehistory, specifically in the age of dinosaurs, grass pollens have been reported by historians, as well as African tribes have used grass species around their villages for hunting and defending enemies. Medieval castles were surrounded with grass to better visualize the horizon of the fortress and the lookout of those who approached it. Over the years, seeds were disseminated to various parts of the world, and the lawn began to be reported in books on botany, and its use in gardens began to gain notoriety. Thus, grass species became part of the population’s daily life, from the Renaissance to the contemporary-modern period, and make up elements of the garden landscape (residential and private) cemeteries, parks, sports fields, roadside, and more recently, on green roofs. In Brazil, with the enhancement of landscaping and the arrival of several types of turfgrasses, the lawn has become a requirement in the construction of a garden. Currently in the Brazilian market, there are thirteen registered different species of turf, which have characteristics and particularities for their use in the constitution of the landscape and landscaping.


Introduction
Landscape refers to an association between the place and its inhabitants, being also defined as "formatting the land, implying an association of physical and cultural forms" (Holzer, 1999).
On the other hand, landscaping consists of the art of creating a specific space (Paiva, 2008), involving environmental, functional, aesthetic value and harmony with the characteristics of the place. Thus, it must have a social function of "providing the population with community relations or coexistence", which are favored by the existence of public parks and squares (Bovo and Amorim, 2012).
In the USA, according to Urmy (2019), there is no landscape as iconic as the lawns, which had great Regina MaRia MonteiRo de Castilho et al. 500 importance in the development of modern urbanization. Studies on "grass" are intertwined between the areas of Agronomy, Biology, Architecture, Ecology and sports. Urban lawns constitute, according to Ignatieva et al. (2020), in the most common part of open spaces and green infrastructure in a city, and provide services to the ecosystem (and also the disservices), in addition to different approaches in the biophysical, social, planning and design aspects, including understanding and valuation of that vegetation.

The grass and the turfgrass in history, landscape, and landscaping Prehistory
The oldest specimens of grasses was registered in 100 million years ago (Poinar et al., 2015), therefore known from a geological period when dinosaurs dominated the planet. Prior to this dating, the oldest one was 70 million years ago, at the end of the "era of dinosaurs" (Prasad et al., 2005), both of which were based on food residues from Sauropoda (long-necked dinosaurs). The origin of the Poaceae family is indicated from molecular data at least 55 million years ago, having occurred in the extinct continent Gondwana (Bouchenal-Khelladi et al., 2010). The first records of grass pollen were from the Paleocene period, in South America and Africa, between 60 and 55 million years ago. This date is after the main extinction events that ended the dinosaur era and the Cretaceous period (Kellogg, 2001).

Middle Ages
One of the initial reports of grass use by men occurs in the middle of the 10 th century, by African tribes, where this vegetation, being herbaceous and in small size, served a dual purpose. They allowed residents and hunters to see the danger approaching from afar (animal or enemy tribe) as well as served as a hideout for hunters, when in pursuit of prey (Haber, 2004). In the medieval period, the first description of sodding (which comes from the word sod, "turf carpet") appears in the 1159 Japanese book "Aatu-tei-kaiI" or "Sakuteiki" (Bread et al., 2014). This was the first text on Japanese garden planning, in which mentions of the turfgrass appear as the focus of the garden (Takei and Keane, 2011). In medieval castles in Europe, the surrounding grass was kept low (Figures 1 and 2), as a strategy for guards to have an unobstructed view of approaching visitors (Hejcman et al., 2013).

The Turfgrass in landscape and landscaping
According to Beard et al. (2014), in the 12 th century, "perennial and low-growing grasses were regularly defoliated by grazing animals or by hand sickles". The same author also mentions that the English literature of the end of the 12 th century and beginning of the 13 th century already showed the sportive use of turfgrass (bowling courts, which would be precursors to the tennis, croquet and golf courts). In the second half of the 13 th century (around 1260), Alberto Magno (1196-1280), theologian, philosopher, astronomer and scientist, wrote a compendium of Botany ("De vegetabilis et plantis libri septem" -Seven books on vegetables and plants ) (Figure 3); the first five books are theoretical, while the last two are of practical application, in which plants and herbs were listed in alphabetical order, and species of grass and their use in lawns have been mentioned (Neves, 2017). Beard and Green (1994) report that during the Renaissance many paintings showed private ornamental lawns and also in public parks. Thus, the turfgrass was portrayed, in 1503, by Albrecht Dürer, in a work entitled "Large Piece of Turf" (Figure 4), and by Giusto Utens, in 1602, who dedicated one of his best "telescopes" to Villa di Pratolino, in which depicts a wide, grassy avenue ( Figure  5) (Tomassi and Hirschauer, 2020).  During this period, a type of football was played on turfgrass in public spaces, being common in most cities and villages in Great Britain, Germany, France, Holland and Austria (Kopec, 2015). In 1665, in Europe, recommendations were published on preparing the beds, selecting grass species (Agrostis and Festuca), harvesting and transplanting to golf courses, with pruning (cutting) being done naturally by sheep (Kopec, 2015). The striking presence of lawns in landscaping during the Renaissance appears clearly in France, in the gardens of Versailles (1624-1688). Designed by André Le Nôtre, shows a symmetrical design, with the great tapis vert (green carpet) with an aesthetic function ( Figure 6), valuing perspective and the feeling of grandeur (Olin, 2017), so that the lawn has become a status symbol. In England, the trend has tended towards more open landscapes, with fewer fences; the democratic liberalism of the English led to the rejection of despotic French governments and, thus, Renaissance gardens. The gardens began to imitate natural landscapes and consisted of large lawns and the incorporation of lakes and rivers with a natural layout (Liu, 2008;East, 2020); among these are those designed by William Kent (1685Kent ( -1748 (2020) In the 19 th century, Napoleon III commissioned Jean-Charles Alphand (1817-1891) to urbanize the "square" Batignolles (Paris) (Figure 9), which opened in 1879, with an artificial lake, tortuous paths and extensive lawns (Stewart, 2012 ), thus giving rise to the eclectic style (Anglo-French garden).

th century
Before the First World War (1914)(1915)(1916)(1917)(1918), landscaping concepts emerged, with a modern language, with angular compositions and segmented plans and surfaces, with wide grassy areas (Walker and Simo, 1996). In 1914, Daniel Bellet and Will Darvillé launched the book Ce Que Doit être la Cité Moderne where they argue that "parks and large public gardens, the vast grounds for games and the spacious green squares are reservoirs of fresh air, and that the massive presence of vegetation and lawns becomes an indisputable element of calm and stillness" (Segawa, 1996).

United States
In the middle of the 17 th century, the USA began to receive immigrants from Northern Europe; who brought grass seeds and other herbs (Jenkins, 2015), which were considered very valuable. In 1672, twenty-two species of herbs had settled around Massachusetts Bay, including grasses (Bread et al., 2014). These grasses spread rapidly across the North American continent, such as the Guinea grass (Paspalum paniculatum) and the African grass (which became known as Bermuda grass) (Cynodon spp.) Which spread across the south; Kentucky bluegrass (Poa pratensis), originally from Europe and the Middle East, which dispersed over the Appalachian Mountains and the Midwest; in the west, it was grasses originating in the Mediterranean, brought by Spanish soldiers and missionaries (Jenkins, 2015). In the early 19 th century, turfgrass was popular in the United States; parks in urban areas began to adopt the European model, with an emphasis on extensive lawns, and thus "green and lush turf" became the dominant feature of the "American way of life" (Jenkins, 2015).
Until the middle of the 19 th century, most houses in the United States were built without indentation, and had a small garden at the back of the house, with this design reflecting the emphasis on privacy attributed to the European residential. The transition to homes with gardens and lawns at the front was related to that advocated by Frederick Law Olmsted, that is, the presence of a public park with extensive green areas with turfgrass, and thus taking the lawns to the homes of ordinary Americans. Frederick Law Olmsted (1822-903) and Calvert Vaux (1824-1895) who designed today iconic public spaces, such as Central Park in New York/USA (Figures 10 and 11), as well as a new look in the residential space, in the suburb of Chicago, at Riverside, in 1869 (Figures 12 and 13), where it included a lawn for each home (Bread et al., 2014).

The contemporary lawn
In many parts of the world, the lawn is the most common of all resources in contemporary gardens, where it has played a significant role in the anthropogenic landscape (Smith and Fellowes, 2013). A more naturalistic approach to garden design began to emerge in the early 1990 s . Movements began in Europe, mainly in Germany, the Netherlands and also in the USA, arising from the growing concern about the need to reconnect with nature (Özgüner et al., 2017), leading to a widespread change in attitude towards the creation of the urban and residential outdoor space, as gardens bring quality to modern life. With the increasing awareness of the population regarding the need for more sustainable development, the landscaping project must be adapt, such as, for example, the use of rainwater collectors and the use of residual water (from domestic sewage) for irrigation of lawns (Alencar and Cardoso, 2015). Contemporary lawns are particularly valued as places for different outdoor activities such as playing, resting, having picnics, walking, socializing (Ignatieva et al., 2017), and are also used in extensive and intensive green roofs, parks and neighborhood green spaces. and zoos (Rall et al., 2015). Thus, a turfgrass is not just an individual object, but it carries the implicit message of being aesthetic, environmental and community (Hodgson, 2015). Among the contemporary urban green spaces, which have as main element extensive areas with lawn, there is the André-Citröen Park (Alain Provost and Gilles Clément) in Paris/ France ( Figure 14) and several landscape projects by Kim Wilkie (Orpheus at Boughton, in Northamptonshire/United Kingdom and Heveningham Hall, in Suffolk/England (Figure 15), among others (Richardson, 2000).

The turf and turfgrass in Brazil
As for the emergence of large lawns in Brazil, Segawa (1996) shows the presence of this vegetation in three situations, among others. In 1786, the English navigator John Barrow (1764-1848), then aged 22, visited Rio de Janeiro and described the Passeio Público (1779) as "an object of utility, in which the public's health and enjoyment was taken into account, being a garden to walk around; this land is laid out with bushes, lawns, boulevards and beds"   However, the use of grass in landscaping in Brazil had its great impetus with the arrival of Auguste François Marie Glaziou (1828Glaziou ( -1906, in 1858, where it remained until 1893. He brought the concept tapis vert -French expression used to designate a large lawn. In the Jornal do Comércio, published on September 7, 1880, regarding the project in Campo de Santana (Rio de Janeiro, RJ) ( Figure 18) it was stated that "The extensive lawns, from where from time to time some bushes stand out, produce magnificent effect" (Terra, 1993). Source : Coleção Gilberto Ferrez (2020).
In agreement with the aforementioned, Segawa (1996) comments that Émile Allain (1877-1951) spoke, in 1886, about the Campo da Aclamação: "During the winter, it is frequent that bad weather drives away sea gulls and that they come to the garden, where its almost white plumage contrasts sharply with the green of the lawn ". In the 1920 s , according to Provenzano et al. (2018), the landscaping of Mina Klabin (1896Klabin ( -1969 appeared; in the residences of Rua Santa Cruz (1927) in Vila Mariana ( Figure 19) and Rua Itápolis (1930) in Pacaembú, both in the city of São Paulo-SP, she used extensive lawns and some species of tropical flora. Burle Marx (1909Marx ( -1994 brings to the landscape, from 1935, according to the same author mentioned above, the character of the garden's exteriority, relating the public space and the surrounding environment, using wide turfgrass spaces in his projects, such as, for example: Gustavo Capanema Building (Rio de Janeiro-RJ), Generalissimo Francisco The Turfgrass in landscape and landscaping de Miranda Park (Caracas-Venezuela), Edmundo Canavelas House (Petrópolis-RJ), etc. Both in the Casa Edmundo Cavanelas (Figure 20), as in the currently called Parque Burle Marx (São Paulo-SP), the checkered lawn, composed of Emerald grass (Zoysia japonica) and St. Augustine grass (Stenotaphrum secundatum), is an important compositional element landscape and artistic design.
In 1960, the concept of "park cemetery" (or garden cemetery) appeared in Brazil, with extensive grassy areas and underground deposits identified by gravestones on the grass ( Figure 21); it is necessary to meet specific technical requirements and conditions for such an undertaking (Pacheco, 2017).  Another use of lawns in contemporary landscaping is on green roofs (Santos et al., 2016;Ntoulas et al., 2017), which was already used by Burle Marx, in the Gustavo Capanema Building, opened in 1954. These are characterized as all coverage of the upper slab of buildings, for aesthetic purposes, improving environmental comfort, capturing and reusing water and preventing runoff, minimizing urban flooding (Santos and Castilho, 2018;Zhang et al. 2018). In Brazil, several municipalities have included public policies with reduced taxes for urban buildings that adopt this technology, such as Porto Alegre-RS (2007) (Figure 22), Taubaté-SP (2016) and Mauá-SP (2017). Green roofs became mandatory only in the city of Recife, for residential buildings with more than four floors (RECIFE, 2015). In the city of São Paulo, since 2015, this system can be used as an option for environmental compensation (SÃO PAULO, 2015).
Currently in the Brazilian, 13 types of turfgrass have been using for different areas (Godoy et al., 2020), with specific purpose, mainly for landscaping, as shown in Table 1.

Zeon grass
Zoysia matrella Fairway areas of golf courses and ornamental gardens.

Paspaulum vaginatum
High performance sports fields *; it is tolerance to salinity.

Geo Zoysia
Zoysia japonica x Zoysia tenuifolia Residential lawns to extensive green areas.
St. Augustine grass Stenotaphrum secundatum Residential and business gardens in coastal regions, due to their tolerance to salinity.
Carpet grass Axonopus spp. Residential lawns, extensive green areas (parks and industries) and semi-shaded locations.

Bahia grass
Paspalum notatum Margins of highways, residential gardens, squares, parks and low performance sports fields.
* the 'Platinum' variety is used in the Qatar 2022 world cup fields.
Among the species in Table 1, the Carpet grass, Seashore and Bahia grass are native to Brazil (Godoy et al., 2012;Souza et al., 2020a). However, the majority of lawns formed by Bahia grass result from planting by "pieces" collected manually in degraded pasture areas (Souza et al., 2020a). Thus, "Embrapa Pecuária Sudeste" (São Carlos, SP) started to conduct research for the production and commercialization of Paspaslum and Axonopus spp. (Souza et al., 2020b) that were recently registered with the Ministry of Agriculture.

Conclusions
Nowadays, great Brazilian landscapers, depending on the style (or mix of styles) make use of extensive grassy areas, given the sense of freedom and tranquility that they bring, making the areas for leisure, recreation or contemplation functional. Citing Cânovas (2015): "the gardens, no matter how small, become more friendly when an area is occupied by a natural carpet, the reason is simple. It is the main responsible in the perspective of the landscaping, and in the depth of the other elements that form the green area, so much so that the English revolutionized the landscape architecture, using the grasses to accentuate the relief of the terrain, thus increasing, the feeling of space and giving a definitive contribution to the garden designer". Finally, it is always worth remembering that in the Letter of Athens/Athens (1933), signed by Le Corbusier and other urban planners. He says that cities must give to the citizen, "in sufficient proportions, elements indispensable to living beings: sun, space and vegetation, fundamental issues both psychological and physiological" (International Congress of Modern Architecture, 1933) (Corbusier, 1993).
