Trees grow with, and adjust to, large lateral and vertical loads caused by wind and gravity. Storms with strong winds and ice can push trees beyond their ability to reconfigure or fall back to reduce drag.
With increased intensification in cities throughout the world, urban trees are often at risk of becoming damaged by construction impacts, such as utility trenching or pavement / sidewalk repair.
Tree planting can help communities achieve many resiliency goals such as cooling heat islands, reducing stormwater floods, and building neighborhood cohesion.
The goal of the webinar is to provide an overview of soil management for urban trees. Specific emphasis will be given to soil assessment.
Thousands of trees are struck by lightning every year. These trees will have varying degrees of damage ranging from complete shattering and destruction of the tree, to a slow lingering death, to virtually no apparent damage at all (Figure 1).

The history of the Morris Arboretum can be told through its eldest trees. Every scar and abnormality present on these immense specimens inspire awe, enrich visitor experience, and provide a glimpse into the past of the gardens.
Tree defects such as co-dominant leaders, girding roots and buried trunk flares, present at time of planting, cause failures and decline long after the warrantee period has expired. Landscape architects may go to nurseries to tag trees; but often inspe
Ice or snow loads can cause branch breakage or failure of entire trees and shrubs. Branches or entire trees that fall in storms can impact homes, vehicles, power lines and block roads.
While green stormwater infrastructure increases in popularity, we are still learning about the role of trees in these innovative practices.
