4 Warning Signs that a Tree Is at Heightened Risk of Collapsing

When tall trees become unstable, they can pose serious dangers. A collapsing tree can damage homes, vehicles, power lines, and, most importantly, put people at risk. While not all hazards are immediately obvious, there are clear warning signs that a tree may be at increased risk of falling. At Arbor Pro Tree Service, our local arborists provide expert hazardous tree removal in the greater Moline, IL area. Recognizing these signs early allows you to take action before disaster strikes.
Large Cracks in the Trunk
The trunk is the tree’s main support system. If you notice large cracks, cavities, or splits running through it, this is often a sign of structural weakness. Severe storm damage, disease, or internal decay can compromise the trunk’s strength, making it more likely to fail under pressure. A compromised trunk should always be inspected by an arborist to determine if removal is necessary.
Leaning or Shifting Position
A tree that is suddenly leaning or has shifted its position in the soil is showing signs of instability. While some trees naturally grow at an angle, a recent or worsening lean suggests problems with the roots or trunk. If the soil around the base appears cracked or lifted, the tree may be losing its anchoring system, increasing the chance of collapse.
Signs of Root Damage or Decay
Roots are critical to a tree’s stability, and damage beneath the surface often goes unnoticed until it becomes severe. Visible signs include mushrooms or fungal growth at the base, soil heaving, or exposed, broken roots. Root decay weakens the tree’s foundation, leaving it vulnerable to falling, especially during high winds.
Hollow or Decayed Interior
A tree may appear relatively fine on the outside but be hollow or decaying on the inside. Cavities, soft wood, or evidence of insect infestations are red flags. While some hollow trees might remain standing for years, the more decay that exists, the less structural integrity the tree has to withstand environmental stresses.
