Introduction
Not all trees showing warning signs are necessarily hazardous, but assessing the level of risk is crucial. In this article, we’ll discuss how to evaluate the risk posed by potentially dangerous trees and when it’s best to consult a professional arborist for an expert opinion.

1. Factors That Affect Tree Risk

• Location: Trees located close to buildings, power lines, or frequently used outdoor areas pose a higher risk if they fail.
• Tree Size and Species: Larger trees with weak wood, such as poplars or willows, tend to be more hazardous in high winds than hardwood species.

2. Tree Inspection Techniques

• Visual Inspection: Begin with a visual inspection from the base of the trunk to the crown. Check for signs of leaning, exposed roots, and unusual branch behavior.
• Sound and Touch Tests: Knock on the tree trunk in various areas. A hollow sound can indicate internal decay, while soft spots often mean rot.

3. When to Call a Professional Arborist

• Complex Warning Signs: If you notice more than one risk factor or signs like mushroom growth, call an arborist for a comprehensive assessment.
• Heavy Branches Over Structures: Branches overhanging homes or garages are best evaluated by a professional. They have specialized equipment to safely remove risky branches.

4. Arborist Risk Assessment Tools

• Resistograph: This tool measures the density of wood, helping assess the tree’s internal structure for signs of rot or decay.
• Climbing Inspection: Arborists can climb the tree to get a close-up view of branches and foliage, identifying hazards that might not be visible from the ground.

Conclusion
Knowing when to call a professional can make all the difference in maintaining safety. If you have concerns, a certified arborist has the tools and expertise to assess your tree’s health and offer recommendations on the next steps.
