How to Spot a Dangerous Tree: Signs Your Tree Might Need Removal

​​Trees add beauty and value to any property, but when they become unstable or diseased, they pose significant risks. Identifying hazardous trees early can prevent property damage, personal injury, and costly emergency removals. In this guide, we’ll discuss key warning signs that indicate a tree may be dangerous and in need of removal.

What Are the Structural Warning Signs of a Dangerous Tree

Leaning Trees

• While some trees naturally lean, a sudden or worsening lean can indicate structural instability.
• Cracked soil or exposed roots near the base can suggest the tree is losing its grip on the ground.
• Trees leaning toward structures, driveways, or walkways are particularly hazardous.

Multiple Trunks or Weak Unions

• Trees with multiple trunks or branches that form a tight V-shape are more prone to splitting.
• Weak unions, where branches join at a narrow angle, can break under heavy wind or ice loads.
• Regular inspections can identify potential weak spots before they cause damage.

Large Dead Branches

• Dead or broken limbs can fall unexpectedly, posing a risk to people and property.
• Branches that are missing bark or have no leaves during growing seasons are likely dead.
• Routine pruning can prevent hazardous branches from becoming a larger problem.

Cracks and Cavities

• Large cracks in the trunk may indicate serious internal decay.
• Cavities or hollow sections weaken the tree’s overall structure and can lead to breakage.
• A certified arborist can assess the severity and recommend whether removal is necessary.

What Are Signs of Disease or Decay in Trees?

Fungal Growth (Mushrooms at the Base)

• Mushrooms or fungi growing at the base of a tree often signal internal rot.
• Trees with extensive fungal infections may become weak and structurally compromised.

Peeling or Missing Bark

• Bark protects the tree’s inner layers; missing or peeling bark can indicate stress or disease.
• Sunken or discolored patches on the trunk are additional signs of declining health.

Sudden Leaf Loss or Discoloration

• Trees that lose leaves prematurely or have yellowing leaves outside of seasonal changes may be unhealthy.
• Thinning canopies or branches with no new growth may indicate disease or root damage.

Insect Infestation

• Termites, beetles, or other boring insects can weaken a tree’s structure.
• Holes in the trunk, sawdust-like residue, or excessive woodpecker activity are common infestation signs.

What Are Sign of Root and Soil Issues in Trees?

Exposed or Damaged Roots

• Root damage from construction, erosion, or disease can destabilize a tree.
• Cutting major roots during landscaping projects can reduce the tree’s ability to anchor itself.

Heaving Soil Around the Base

• Soil that appears lifted or cracked near the tree’s base may indicate root movement.
• This can be an early warning that the tree is shifting and at risk of falling.

What to Do If You Have an Unhealthy Tree?

Consult a Certified Arborist

• A professional tree assessment can determine whether a tree can be saved or needs removal.
• Arborists use specialized tools and knowledge to detect internal decay and structural weaknesses.

Pruning vs. Removal

• If only certain branches are compromised, pruning may be enough to improve stability.
• Trees with extensive decay, severe leaning, or compromised root systems often require full removal.

Emergency Tree Removal

• If a tree poses an immediate danger, such as after a storm, emergency removal services may be needed.
• Never attempt to remove a large or hazardous tree on your own—always call a professional.
