Trees are valuable to any property, providing shade, beauty, and environmental benefits. However, unhealthy trees can become hazardous, posing risks to people and property. Identifying dangerous trees is essential for maintaining safety and preventing costly damage. Recognizing the signs of tree hazards and knowing when to consult a tree care specialist can help property owners make informed decisions about tree management and removal.

Visual Inspection

The first step is a visual inspection. Regularly observing trees can reveal early signs of potential problems. It’s important to examine the tree from different angles, both from a distance and up close.

Root System

A tree’s root system is crucial for its stability and overall health. Signs of root issues include:

• Visible root decay or damage
• Soil around the tree base heaving or cracking
• Exposed roots due to soil erosion
• Fungal growth near the tree’s base

Compromised root systems can weaken a tree’s ability to withstand strong winds or heavy loads, increasing the risk of falling.

Trunk Condition

The trunk is the tree’s main support. Inspecting it can reveal several potential hazards:

• Cracks or splits in the trunk
• Large cavities or decay
• Multiple trunks with weak attachment points
• A leaning trunk (especially if the lean is new)

Significant trunk damage can compromise the tree’s structural integrity, making it prone to failure.

Branch Structure

Assessing the branches helps identify potential hazards. Look for:

• Dead or dying branches
• Branches with weak attachments to the trunk
• Overextended or heavy branches
• Branches that cross or rub against each other

Weak or damaged branches are more likely to break, especially in storms or high winds.

Canopy Health

The overall health of the tree’s canopy can indicate underlying issues:

• Thinning or sparse foliage
• Discolored or undersized leaves
• Premature leaf drop
• Excessive deadwood

A declining canopy may signal health problems that could compromise the tree’s stability.

Environmental Factors

Consider environmental conditions when evaluating tree hazards:

• Recent construction or changes in soil near the tree
• Exposure to severe weather
• Proximity to structures, power lines, or busy areas
• Competition with other trees for resources

Environmental stress can weaken trees over time, increasing the likelihood of failure.

Professional Assessment

While property owners can conduct visual inspections, consulting a tree care specialist is often necessary for a thorough assessment. Professional arborists have the expertise and tools to detect less obvious signs of hazards and provide detailed recommendations for management or removal.
