Will This Tree Fail? Recognizing and Mitigating Conditions of Concern in Urban Trees

Start Date/Time:

End Date/Time:

Trees are built to withstand the forces they have grown to endure. Given enough time, however, all trees will develop structural defects. Many defects pose negligible risk to the surrounding environment or to the tree itself. On the other end of the spectrum, severe defects can lead to catastrophic failure. While many defects such as large cavities or broken branches are easy to recognize, others can be more subtle.

After the Storm: Crown Restoration Pruning of Storm Damaged Trees

Start Date/Time:

End Date/Time:

Storm damage is a common issue faced by urban tree managers. Sometimes trees are severely damaged and need to be removed. Many more, however, receive moderate levels of damage and can be saved. When tree branches get damaged during storms they typically respond through the production of sprouting branches. Sprouts are a critical component in replacing the tree’s photosynthetic capacity. As the new branches grow and develop, restoration pruning becomes an important process to help improve the structural integrity of the tree crown.
