When evaluating a tree what do you consider?

I consider a full spectrum of arborist services based around a "Whole-Life Continuum" that encompasses planning-preparation-mitigation-response-and recovery of the tree in question. Every tree is an individual and must be assessed as an individual when considering its present condition and also its future footprint. Hazards reduction, as well as risk mitigation, are typically the main effort when considering whether to reduce the canopy, heavy trimming, fertilizing or partial to full removal of the tree based on industry standards.
