Risk concerns often involve the trunk, root zone, site conditions, nearby targets, and visible defects.

Common tree risk concerns

Common concerns include dead branches, cracks, cavities, leaning trees, root damage, soil movement, fungal growth, storm damage, and trees near homes, roads, playgrounds, parking areas, or utilities.

Why risk assessment is different from routine tree work

Risk assessment involves evaluating the likelihood and consequences of tree or branch failure. This may require specific training, documentation, and judgment beyond routine pruning or removal estimates.

When a written report may be useful

Reports may be useful for property management, insurance, real estate, legal disputes, municipal review, construction planning, or when multiple parties need a documented opinion.
