“…Thanks to human management, the adaptive capacity of urban trees varies substantially according to the array of environments of streets, parks, and roadsides, and they could exhibit adaptive features very different from natural forests [27][28][29]. For example, a park tree would have a more extensive root structure and moister soil than that of a drier roadside tree in compact paved soil [30].…”

Urban trees in a densely populated environment may pose risks to the public’s safety in terms of the potential danger of injuries and fatalities, loss of property, impacts on traffic, etc. The biological and mechanical features of urban trees may change over time, thereby affecting the stability of the tree structure. This can be a gradual process but can also be drastic, especially after typhoons or heavy rainstorms. Trees may fall at any time with no discernible signs of failure being exhibited or detected. It is always a challenge in urban tree management to develop a preventive alert system to detect the potential failure of hazardous urban trees and hence be able to have an action plan to handle potential tree tilting or tree collapse. Few studies have considered the comparison of tree morphology to the tilt response relative to uprooting failure in urban cities. New methods involving numerical modeling and sensing technologies provide tools for an effective and deeper understanding of the interaction of root-plate movement and windstorm with the application of the tailor-made sensor. In this study, root-plate tilt variations of 889 trees with sensors installed during Typhoon Higos (2020) are investigated, especially the tilting pattern of the two trees that failed in the event. The correlation of tree response during the typhoon among all trees with tilt measurements was also evaluated. The results from two alarm levels developed in the study, i.e., Increasing Trend Alarm and Sudden Increase Alarm indicated that significant root-plate movement to wind response is species-dependent. These systems could help inform decision making to identify the problematic trees in the early stage. Through the use of smart sensors, the data collected by the alert system provides a very useful analysis of the stability of tree structure and tree health in urban tree management.

“…Regularity in the drill must be given regular drilling depth and width and from all sides and a flat floor and the walls are straight, and may not be edited in the specified elevations without the approval of the supervising engineer 4. The nature of the excavations: the depth of drilling or decrease according to what he sees as the supervising engineer, for example, possible drilling to depths identified in the drawings can be increased, but the supervisor engineer may notice the hole in the rock layer site you need to drill further increase in the depth asks drilling, or vice versa in some cases not possible to complete the drilling depths identified in the drawings as the supervisor engineer noted that the size of the hole and the nature of the soil suitable for planting (Jim &Ng,2018 andJim,2021).

Afforestation is one of the most important means to protect cities from climatic conditions. It is proper for cities like Ramadi (the study sample) to face extreme weather during summer. This study was conducted to rely on afforestation to improve Ramadi's climate and identifying plants species that are suitable for planting as well as clarify the way on how to implement afforestation projects inside and outside the city. The study found that the city suffers from high temperatures, low rainfall, relative humidity and blowing warm dry wind loaded with dust. This is a result of the lack of afforestation inside and outside the city, as well as the lack of experience in selecting and cultivating suitable vegetation for the climate and soils of the city, The results showed the great role of afforestation in certain environments in addition to identifying appropriate plant species for the climate and soils of Ramadi, the development of scientific steps to implement afforestation projects, plus a number of recommendations that would raise environmental, functional and engineering efficiency of afforestation planning.
