Introduction: As arborists and tree surgeons, it’s essential to have a deep understanding of tree anatomy to ensure the health and safety of trees during various tree care procedures, including dismantling. The branch collar is a crucial element of tree anatomy that plays a significant role in dismantling. This blog post will delve into the importance of understanding branch collars in tree dismantling and how Canterbury Tree Surgeons prioritises tree health and safety in our tree care practices.

The Significance of Tree Anatomy:

Trees are complex organisms with intricate structures that provide stability, transport nutrients, and support growth. A thorough understanding of tree anatomy is crucial for any tree care professional, as it guides decision-making when performing procedures like pruning or dismantling.

What Is a Branch Collar?

A branch collar is a bulging or swollen area where a branch attaches to the trunk or another branch. A slightly raised bark ring often characterises it and is a critical feature in tree anatomy. The branch collar plays a significant role in a tree’s defence mechanisms and overall health.

The Role of Branch Collars in Dismantling:

• Natural Defense Mechanism: The branch collar acts as a natural barrier that helps prevent the spread of decay and disease from the branch into the trunk. When a branch is pruned or removed incorrectly, cutting or damaging the collar can compromise the tree’s ability to defend itself.
• Support and Healing: The branch collar contains specialised cells that promote healing and sealing of the wound after a branch is removed. Preserving the branch collar during dismantling is essential to ensure proper healing and reduce the risk of infection.
• Preventing Structural Weakness: Cutting too close to the trunk or leaving a stub during dismantling can lead to structural weakness in the tree. The branch collar supports the tree, and preserving it helps maintain its integrity.
• Minimising Stress: Proper dismantling techniques that preserve the branch collar minimise stress and damage to the tree. This is especially crucial when dealing with older or mature trees.
