What are Girdling Injures?

Girdling Roots

This kind of injury causes the destruction of vascular tissue and interrupted  flow of nutrients and photosynthate in the trunk regions of trees. Lawn mowers, string trimmers, synthetic bags, guy wires and ropes left on too long and rodents feeding are ways in which these injuries occur.

The lower trunk of a tree is a very crucial part of its anatomy.  Such wounding requires the tree to use up energy reserves in order to perform wound response and initiate callus tissue. When a tree has reduced energy reserves it is more susceptible to infection by opportunistic pathogens. Lower trunk wounds are a good point of entry for those pathogens.

Girdling Roots are roots that are growing across the main trunk or root flares and are strangling the transport system of the tree.  Where possible, these should be removed with caution.

Avoiding Tree Damage During Construction

Unfortunately, the processes involved with construction can be deadly to nearby trees. Unless the damage is extreme, the trees may not die immediately, but could decline over several years. With this delay in symptom development, you may not associate the loss of the tree with the construction.

It is possible to preserve trees on building sites if the right measures are taken to prevent the following:

  • Physical injury to trunk and crown
  • Cutting of roots
  • Soil compaction & contamination
  • Smothering roots by adding soil
  • Exposure to the elements

The value of the trees on your property and the importance of saving them needs to be communicated with your builder. Few builders are aware of the way trees’ roots grow, and what is needed to protect them. Educating and working together in planning is essential.

Get in writing all of the measures intended to protect your trees. Erecting barriers, limiting access and sometimes small changes in the placement or design  will be crucial to their survival. So remember, before you add an addition, install a pool or change your landscape, be sure to consult with our certified arborists first. or (416) 410-8770
