“…Next, all construction projects with building permits must be filed with a tree preservation plan that properly lists the building activity area and tree preservation area. If a tree removal permit is approved, it is an inevitable need for a tree replacement where the number and species of the replacement trees is strongly dependent on the afforded protection level of the tree removed [17].…”

The sustainability of construction projects is an important issue to address since the sector will grow rapidly, especially in developing countries. Excessive resource consumption and climate change due to construction activities have become critical for countries such as Malaysia which have limited natural resources water, electricity and other natural resources. It has increased pressure among construction stakeholders to adopt sustainable practices, especially during the construction phase. As builders of any construction project, contractors play an important role in promoting sustainable development to minimize negative impacts on the environment and society while maximizing their economic contribution. As a result, this research is to investigate the influence of contractors’ sustainable practices during a project’s construction phase and the project’s competitiveness. Forty-five (45) contractors from G1 – G7 are involved in collecting their standpoints on sustainable practices through an online questionnaire survey. Statistical Package for the Social Science (SPSS) was used to analyse the collected data by conducting the Frequency Analysis and Mean Analysis. This study found that the most potential sustainable practice to be implemented is the ‘reduce method’ due to it is the most effective and efficient method to achieve the low production of construction wastes that meets the purpose of sustainability. While the improved image is found as the top potential competitive advantage for contractors when implementing sustainable practices to have a good corporate image to expand their businesses further. As sustainable practices are becoming more crucial, this study provides insight for contractors to foresee the benefits of adopting sustainable practices to increase their project competitiveness further.

“…Perhaps the most effective approach to protecting streetside trees is to ensure a resilient and healthy soil environment for optimal growth and longevity (Pike et al, 2021). GI designs that provide ample soil volumes minimize compaction and encourage the formation of microbiological−especially mycorrhizal−communities beneficial to the health of trees (Calvo-Polanco et al, 2008 offer protection against the harmful effects of salt contamination.…”

Winter Climate Variability, De-Icing Salt and Streetside Tree Vitality

De-icing salts are applied to roads and walking surfaces to mitigate winter hazards resulting from ice, snow and freezing rain. The vitality of streetside trees, especially those growing in densely built urban areas, is compromised by repeated exposure to de-icing salts. Such trees already experience unfavorable establishment and growing conditions resulting from poor soil quality, inadequate moisture, physical abuse and air pollution−exposure to de-icing salt aggravates these challenges and can be an essential catalyst in tree mortality. Climate change is creating less predictable weather and, in some cases amplifying the intensity of winter storms. Cities that undertake snow and ice management may adopt modified approaches, and those less familiar with this practice may require its episodic adoption. We identify three pathways by which future climate warming may, counterintuitively, result in cities increasing their use of de-icing salt: (a) Warming winter temperatures in cities that were historically too cold to make effective use of sodium chloride (NaCl) for de-icing; (b) cities where daily high temperatures in winter may increase the frequency of freeze-thaw cycles; and, (c) cities in North America and Eurasia that may experience more severe winter weather resulting from greater variability in the circumpolar vortex (CPV). To offset potential damage to existing urban streetside trees and to ensure adequate soil and growing conditions for future trees, there is an immediate need for city foresters to collaborate with traffic safety and public works departments. We present a toolbox of approaches that can facilitate synchronized management efforts, including identifying the location of existing vulnerable trees and re-envisioning future infrastructure that would mitigate tree exposure to de-icing salts. At the same time, we call for the prioritization of research that investigates new potential pathways along which climate change may contribute to the novel adoption of de-icing salts.

“…Via land-use adjustments, the trees used for natural resources will be preserved, and this positive pattern has been seen in many places [39]. Pike et al [40] found that trees used for natural goods have been maintained for financial and decorative reasons on private property. The practical uses of urban greenspace for individuals are illustrated by urban inhabitants [41].…”

Roads have a great impact on the structure and functioning of the diversity pattern in an ecological environment and play the role of altering biotic and abiotic factors. Clusters of plants grow along the roadside due to the interplay between the arrival of propagule and seedling establishment, which depends on the road's specifications, land pattern, and road administration and protection practices. It is very important to study the diversity pattern in a metropolitan city to improve the ecological environment. Karachi is one of the world's largest and fastest-growing metropolitan cities; however, little is known about the urban forest of the area. In Karachi, which is in the province of Sindh, Pakistan, roadside trees along various road types (e.g., wide, medium and narrow roads) have been studied. Based on a field study, various measures of diversity were utilized to investigate the diversity of tree species on different types of paths. A total of 180 plots, divided into three primary road groups, were surveyed. The highest quantity of tree biomass per unit area was found on wide roads, followed by medium roads. On narrow roads, the least biomass was detected. A single species or a limited number of species dominated the diversity of species. Conocarpus erectus was the most dominant nonnative species along all types of roads, followed by the species Guaiacum officinale. A total of 76 species (32 non-native and 44 native) that were selectively spread along the roadsides of the city were studied. There was a significant difference in phylogenetic diversity (PD), phylogenetic mean pairwise distance (MPD) and phylogenetic mean nearest taxon distance (MNTD) between wide, medium, and narrow roads. Management practices have a significant positive correlation with diversity indices. Our study identified patterns of diversity in roadside trees in Karachi. It provided the basis for future plant conservation planning, such as the conservation of plant species, the maintenance of plant habitats, and the coordination of plant management in Karachi.
