After the Storm: Recognizing Tree Hazards Before They Become Emergencies

This spring, Southern Ontario was hit hard by multiple ice storms, coating trees in heavy layers of ice, snapping branches, and exposing underlying weaknesses. In the aftermath, many homeowners and property managers found themselves facing broken tree limbs, fallen trees, and unexpected cleanup bills. These events served as a powerful reminder of how crucial it is to stay ahead of tree hazards before nature tests their limits.

Even healthy-looking trees can have hidden dangers that compromise safety and property. Recognizing the early signs of structural problems can help you avoid costly damage and, more importantly, keep people safe.

What Is a Tree Hazard?

A tree hazard refers to any structural defect that compromises the stability of a tree and increases the likelihood of failure, whether it’s a falling limb or the collapse of the entire tree. These defects become especially dangerous when combined with external stressors like wind, ice, or decay.

When a hazardous tree is located near a potential target, such as a home, or vehicle it poses a direct risk. Identifying and addressing these risks early is essential to prevent property damage and ensure safety.

Top Tree Hazards to Watch For

Here are some of the most common signs that a tree might pose a safety concern:

  1. Dead or Hanging Branches
    Deadwood is brittle and prone to breaking, especially during storms. Look for bare branches with no buds or leaves in the growing season.
  2. Cracks or Splits in the Trunk
    Vertical splits or open cracks in the trunk or large limbs can indicate internal stress and weakness.
  3. Leaning Trees
    While some trees grow naturally at an angle, a sudden lean or one that’s increasing over time may be a red flag, especially if roots are lifting on one side.
  4. Mushrooms or Fungal Growth
    Fungi growing at the base of a tree or along its trunk can indicate internal rot or root decay.
  5. Cavities or Hollow Spots
    Large holes in the trunk or major limbs can weaken structural integrity and may house pests or further decay.
  6. Poor Root Health
    Exposed roots, root damage from construction, or soil compaction around the base of the tree can severely impact stability.
  7. Co-dominant Stems
    When two or more trunks grow from the same point, they may compete for space and create a weak junction, prone to splitting under pressure.
