The ecosystem services provided by urban afforestation depend on the size and health of trees and palms, which in these places can be negatively or positively affected by biotic, abiotic, climatic and anthropogenic factors (VAZ MONTEIRO; LEVANIČ; DOICK, 2017). The results of this study show that the growth in diameter, height and volume varies m according to the type of the studied plant, monocot or Eudicotiledonea with the origin of these species native of the Atlantic, Brazil or exotic and with age of individuals.
The woody plants and palm features ra m different growth rates 0.0279 ± 0.0274 and 0.0139 ± 0.0119 m³ ind-1year-1, respectively, mainly due to morphological differences that alter growth secondary education of individuals. In eudicotyledons, a group of woody species, secondary growth is characterized by the production of secondary xylem and the development of new protective tissues from the exchange rate (OLIVEIRA, 2011). In contrast, monocotyledons, such as palm trees, show an increase in stem diameter due to the division of fundamental tissues, these being primary growth structures (BOTÂNICO; ANGYALOSSY, 2013), which often limits the size of individuals compared to trees. Among tree species, the greatest increase in Anadenanthera macrocarpa may have occurred due to the adaptation of the species to adverse environmental conditions, with tolerance to shallow, compacted and even poorly drained soils (GONÇALVES et al., 2008). Murraya paniculata was the woody species with the lowest growth because it is a shrub (CHOWDHURY; BHUIYAN; YUSUF, 2008) with smaller size in diameter and height among all the analyzed species. Among the palm trees, the difference in the average increase in volume is due to the characteristic size of the species studied.
The average annual volumetric increase of woody species in the urban environment, 0.0279 ± 0.0274 m³ ind-1 year-1, is higher than that found for Araucaria angustifolia, in two phytographic regions of Rio Grande do Sul, where there is a natural occurrence of the species with a maximum IMAv of 0.0198 m³ and 0.026 m³ (HESS; SCHNEIDER, 2010). In comparison with these data, the average growth of woody species in the urban area was lower than only a third fragment, which presented an average IMAv equal to 0.031 m³ year-1 (HESS; SCHNEIDER, 2010). In planting at the Embrapa Experimental Field in the Western Amazon, an IMAv of 0.039 m³ ind-1 year-1 was estimated for the species Sclerolobium paniculata and between 0.019 m³ ind-1 year-1 and 0.004 m³ ind-1 year-1 for Hymenae courbaril, Carapa guianensis, Bertholettia excelsa, Swietenia macrophylla, Copaifera multijuga, Cedrela odorata, Trattinickia burseraefolia and Dipteryx odorota (SOUZA et al., 2008). The volumetric growth of the studied species is greater in the urban environment than in forest fragments or plantations, which may be due to the absence or little competition. The lower density of trees in an area urban reduces the competition for light and other resources, thus fostering growth (McHALE et al., 2009), and consequently the provision of ecosystem services. Higher tree growth rates in the urban environment are also related to the climate in these locations, characterized by the effect of the heat island that causes higher temperatures in cities and can stimulate photosynthetic activity and extend the plant's growing season (PRETZSCH et al., 2017). It is important to note that the growth rate of trees and palms in the urban environment that are larger than in forest fragments also implies a faster aging of these individuals, thus indicating the need for their replacement and replanting (PRETZSCH et al., 2017). The existing variation also indicates the need to take into account the growth in the choice of species to compose urban afforestation.
Species of palm trees and woody native Atlantic Forest to and naturally occurring in Brazil showed higher average growth rates in diameter, height, and therefore volume. Native species also showed growth rates higher than the Exotic to s ex post when the s at the same level of light, for example, in Connecticut, USA (MARTIN; KOBE, 2010). And exotic species may have shown lower values as a result of adverse environmental conditions, even with some plasticity for adaptation (MUÑOZ et al., 2015; MARTIN; CANHAM; KOBE, 2010). The temperature and precipitation significantly influence the growth of the trees (VITALI; BÜNTGEN; BAUHUS, 2018), and variations between the place of origin of the species can contribute to the reduction of the increase rates. These factors even affect the species' vitality (WILLIAMS et al., 2012), and can cause individuals to become senescent at an early stage. Climate change has altered the frequency of extreme events and this will continue to alter the growth of species, including native species, and it is important to include these effects in growth projections (ZIMMERMANN et al., 2009).
The groups of plants studied, palm and woody, showed variation in growth according to age, being for the first group, the highest rates in individuals up to 20 years old, and for the second, those between 20 and 40 years old. This variation stems from the fact that the relationship between diameter / height and age are non-linear and, in the juvenile stage, growth occurs at a faster rate (VAZ MONTEIRO; LEVANIČ; DOICK, 2017). The increase in tree dimensions with increasing age causes these individuals to reach stages with limited availability of growth factors, light, water and nutrients, which explains the growth patterns in sigmoidal form (KÖHL; NEUPARE; LOTFIOMRAN, 2017). At advanced ages, even at lower rates compared to the juvenile stage, urban trees and palms continue to grow, which has implications for the provision of ecosystem services and also for the need for management of individuals.
The ecosystem services provided by trees and palms in the urban environment are influenced by different factors, such as age, size, spacing, free area. The interception of rainwater, for example, varies according to the species and size of the individuals, with those with PAD close to 3.5 cm intercepting about 15.3%, while those with 38.1 cm of DAP, can intercept up to 66.5% (XIAO; McPHESON, 2002). Larger trees also tend to remove and store more carbon dioxide, in addition to retaining more airborne pollutants (GRATANI; VARONE, 2006). In Rome, trees with DBH ranging from 50-80 cm, tend to remove, on average, 72% more carbon dioxide than those with DBH between 20-50 cm (GRATANI; VARONE, 2006). Thus, the growth rates of trees are indicative of carbon neutralization, expansion of the occupied area above and below ground and, consequently, provision of many ecosystem services (PRETZSCH et al., 2017). Thus, the sustainable management of the population will trees in a city can help mitigate the negative impacts of climate change and maximize the benefits generated, using, for this, information on growth rates, dimensional changes that depend on the age and situation (RÖTZER et al., 2019).
