What is the primary purpose of performing a root collar examination?

The primary purpose of performing a root collar examination is to identify possible girdling roots or decay that may compromise tree stability. This assessment focuses specifically on the area where the roots meet the trunk, which is critical for understanding the overall health and stability of the tree.

Girdling roots can wrap around the trunk and restrict nutrient flow, potentially leading to tree decline or failure. Additionally, examining for decay in the root collar region helps determine if the structural integrity of the tree is at risk. This examination is crucial for ensuring that any issues are caught early, allowing for intervention strategies that might improve the tree's health or safety.

While assessing tree health through visual inspection, examining soil conditions, and estimating age are all valuable components of tree care and management, they do not directly address the critical structural risks associated with girdling roots and decay at the root collar. Thus, the essence of a root collar examination is specifically related to evaluating factors that influence tree stability.
