Under what conditions is tree failure often predictable and preventable?

Predicting and preventing tree failure is most feasible during "normal" weather conditions. During these times, trees are subjected to consistent weather patterns and environmental conditions, allowing arborists to assess their health and structural integrity more accurately. In normal conditions, one can observe signs of stress, disease, or structural weaknesses without the interference of extreme external forces like high winds, heavy rains, or icy conditions, which can mask underlying issues.

Regular maintenance practices such as pruning, soil assessment, and monitoring for pests or diseases can be implemented effectively during stable conditions. Additionally, it is easier to evaluate tree stability and make necessary adjustments or interventions, such as cabling or bracing, which can prevent future failures. In contrast, during heavy storms or winter months, predictive assessments can be more challenging due to the external stressors involved. Newly planted trees, while requiring close attention, do not present a universal condition for failure that can be systematically predicted or prevented in the same manner as established trees in stable conditions.
