How does urbanization impact tree risk?

Urbanization significantly impacts tree risk primarily by increasing stress on trees due to factors like compacted soils, limited space, and altered water drainage. As cities expand, the construction and development processes often lead to soil compaction, which restricts root growth and reduces a tree's ability to access essential nutrients and water. Limited space in urban areas can also result in trees being planted too closely together or in places where their growth is inhibited, further exacerbating stress.

Moreover, altered water drainage patterns in urban environments can lead to either waterlogging or drought conditions, both of which can negatively affect tree health. This combination of stressors can make trees in urban settings more vulnerable to diseases, pests, and other environmental stressors, ultimately increasing their risk of failure and other hazards. Understanding these urban-specific challenges helps tree care professionals assess and mitigate risks effectively in these densely populated areas.
