The importance of trees in urban environment is now widely recognized as they cleanse the particulate air pollution and help to make cities and towns more agreeable places to dwell upon. A detailed survey was conducted to study the size of Alstonia scholaris, Azadirachta indica, Bombax ceiba, Cassia fistula, Eucalyptus sp., Ficus benghalensis, Ficus religiosa and Guaiacum officinale trees in the urban environment of Karachi, Pakistan. Results showed a wide range of variation in tree diameter breast height (17.12-65.50 cm) at M. A. Jinnah Road, University Road (near Hassan Square), North Nazimabad and Karachi University Campus, respectively. A. indica, Eucalyptus sp., and F. benghalensis showed less dbh (tree diameter breast height) at M. A. Jinnah Road as compared to University Road (near Hassan Square), North Nazimabad and Karachi University Campus, respectively. G. officinale growing at University Road (near Hassan Square) showed  ess tree dbh as compared to M. A. Jinnah Road and Karachi University campus. Similarly, the tree size of B. ceiba and A. scholaris was recorded less at Nazimabad as compared to M. A. Jinnah Road, University Road (near Hassan Square) and Karachi University Campus, respectively. C. fistula growing at North Nazimabad site showed low tree dbh as compared to University Road (near Hassan Square) site. A. scholaris growing at Karachi University Campus site showed highest dbh value as compared to all studied sites. The tree size of G. officinale was recorded highest at M. A. Jinnah Road as compared to North Nazimabad, University Road (near Hassan Square) and Karachi University Campus, respectively. Whereas, Eucalyptus sp. and F. benghalensis recorded highest dbh at North Nazimabad site as compared to M. A. Jinnah Road, University Road (near Hassan Square) and Karachi University Campus, respectively. More research is needed on these trees for healthy environment of city. The present study recommends for the complete documentation of tree species growing in city. Such information will be useful to identify characteristics that can be used to select tree species that are better suited for planting on other areas of the city. These findings can be helpful for arboriculturists, environmental scientists and town planners when working on plantation in the selected area.Keywords: Circumference, diameter at breast height, size, roadside tree, urban environment, Pakistan

The City

Due to the rapid development of urban areas, the environment is undergoing significant changes. This also applies to the visual environment. Man deforms the appearance of the natural environment, adjusts to himself, constantly bringing new and new architectural structures and elements. However, solving the problems of urban infrastructure has exacerbated the problems of visual comfort. Therefore, there is a need for a clear assessment of the visual environment. Purpose. To determine the qualitative characteristics of the video-ecological situation of the Kholodnogirsk administrative district of the city of Kharkiv. Methods. Field research and assessment of the visual environment of the city district; method of objective assessment by photofixation; quantitative method of assessing the aggressiveness of the visual urban environment; method of calculating the index of severity of the lesion and the degree of lesion of White Mistletoe. Results. The various visual fields of the urban environment, homogeneous and aggressive, were investigated and determined. The smallest indicator of the homogeneity of the visual environment in the Kholodnogirsk district of Kharkiv is observed around the territory of the Yunost Park – 3%, the largest – around the park on the Volonteer Street - 55%. It is determined that the index of aggressiveness of the visual environment varies from 0.66 to the maximum possible 1. The degree of landscaping of the Kholodnogirsk district of the city of Kharkiv is established. The maximum rate of landscaping - 37%, determined in the park on the Volonteer Street and the minimum - 6% on the Pryvokzalʹna ploshcha. The results of calculations of the index of severity of damage and the degree of damage to trees of recreational areas of the area by mistletoe (Viscum album L.) showed - severity index – 10.5% and degree of damage – 27.3%, observed in Tivoli Garden, the smallest – in Yunost Park – 3.4% (index of seriousness) and the square of O. I. Meshchaninov Square – 8% ( degree of damage to tree species). Conclusions. In recent years, there has been a significant deterioration in the visual environment in cities where most of the population lives. It was revealed that for the territory of the Kholodnogirsk district of the city of Kharkiv, the highest homogeneity indicators are inherent in locations with old buildings, and aggressiveness is in a new building. This demonstrates the need for a well-equipped recreation areas that can "mask" of visual ground discomfort urbogeosystem. An important component of the comfortable visual environment of the city - landscaping, for the Kholodnogirsk district of Kharkiv, in accordance with the standards, is not sufficient. One of the most important factors in reducing the number of green areas is the invasion of tree species by mistletoe (Viscum album L.) It is necessary to focus the attention of local authorities on videoecological problems requiring a comprehensive solution.

<p><strong>Abstract</strong>: Rapid growth of urban population and consequential increasing traffic, construction of buildings, roads, industrial areas, affects urban soils as well as urban environment in general. Urban soils differ from the natural soils by their disturbed structure resulting from waste disposal, construction sites, pollution from atmospheric deposition, traffic and industrial activities. Mismanagement of urban environment can cause severe contamination of green areas in cities, with serious health risk for urban population. To prevail those issues and improve the sustainability of urban green areas, innovative and nature based solutions (NBS) should gain more attention, particularly those easily applied such as tree-based phytoremediation. Unlike traditional remediation techniques that are expensive, very demanding and can cause secondary pollution, tree-based phytoremediation is NBS with wide spectrum of application. It is low-cost technique, based on urban green infrastructure (parks, alleys, community gardens) and has numerous benefits reflected throught sustainable management of urban soils and improvement of general environmental, health, social and economic conditions for urban population. Primarly, urban green infrastructure consist of different tree species capable to mitigate soil contamination, especially contamination with toxic heavy metals (HMs). Regeneration of urban ecosystems based on the role of tree species is connected to ability of trees to retain, uptake and decompose pollutants (including HMs) from contaminated urban soils, enabling their re-use process and turning them into green and environmental friendly areas. Taking into account advantages of phytoremediation technique, the aim of this paper is to present concentration of some HMs (cadmium, lead and zinc) in urban soils of cities accross Bosnia and Herzegovina and look into phytoremediation potential of common urban tree species: horse chestnut (<em>Aesculus</em> <em>hippocastanum</em> L.) and planetree (<em>Platanus</em> × <em>acerifolia</em> (Aiton) Willd.). Results showed high phytoremediation potential of above mentioned tree species, which opens space for further research and introduction of this NBS for remediation of many severely polluted urban soils, drawing attention to better-understood urban sustainability and importance of application of phytoremediation as NBS on local level.</p><p><strong>Key words</strong>: nature-based solutions, phytoremediation, urban soil, trees, heavy metals</p>
