What is a key element to look for when assessing a tree's health?

When assessing a tree's health, identifying signs of decay is crucial because these indicators can often highlight underlying issues that may compromise the tree's structural integrity and vitality. Specifically, the presence of cavity formation suggests that internal decay is occurring, which can weaken the tree and make it hazardous. Discoloration in the bark or foliage can also point to health problems, such as fungal infections or nutrient deficiencies.

Evaluating these symptoms allows arborists and tree care professionals to make informed assessments regarding the tree's condition, potential risks, and management strategies. Addressing decay early can help prevent further decline or failure, making it a key element in a comprehensive tree risk assessment. Other factors, while they may provide some insight into the tree's environment or aesthetic value, do not directly reflect the tree's internal health and stability as clearly as signs of decay.
