What does a consulting arborist do?
A consulting arborist provides independent professional advice about trees, landscapes, plant values, risk, damage, disputes, and other tree-related matters. Depending on the assignment, the work may include investigation, appraisal, risk assessment, documentation, consultation, or expert opinion.
When should I hire a consulting arborist instead of a tree service?
A consulting arborist is especially useful when you need an independent evaluation or professional opinion rather than tree removal, pruning, or other physical tree work. This can be important in disputes, legal matters, insurance claims, appraisals, risk assessments, and complex property issues involving trees.
What does an arborist expert witness do in a legal case?
An arborist expert witness provides specialized knowledge about tree-related issues that may be important to a legal matter. The work may involve reviewing evidence, inspecting trees or property, evaluating tree condition or damage, preparing reports, assisting attorneys, and providing expert testimony when required.
How is the value of a tree determined?
Tree value may be determined differently depending on the circumstances. Factors can include the tree’s size, species, condition, location, function, marketability, replacement considerations, and the purpose of the appraisal. Different appraisal methods may be appropriate for different types of losses or disputes.
What is a tree risk assessment?
A tree risk assessment evaluates the likelihood and potential consequences of tree failure. It involves more than simply looking at whether a tree appears healthy. A qualified assessment considers tree structure, defects, site conditions, potential targets, environmental factors, and recognized failure patterns.
Can a consulting arborist help with insurance claims involving trees?
Yes. A consulting arborist may assist insurance professionals and property owners with tree-related claims involving damage, tree condition, risk, failure, or valuation. Independent arboricultural expertise can help clarify technical questions that may affect the handling or evaluation of a claim.
When do I need an arborist expert witness for a tree dispute?
An arborist expert witness may be needed when a tree dispute involves questions about tree condition, failure, damage, value, risk, maintenance, or accepted arboricultural practices. A consulting arborist can investigate the facts, provide an independent professional opinion, prepare reports, and provide expert testimony when specialized tree knowledge is important to the matter.
How does an arborist determine who is responsible when a tree falls?
An arborist can investigate the tree-related facts that may affect responsibility after a tree falls. This may include the tree’s condition before failure, defects, root problems, maintenance history, site conditions, construction activity, weather, and whether warning signs were present. The arborist provides the technical findings; legal responsibility is determined under the applicable law.
How is the value of a damaged or destroyed tree calculated?
The value of a damaged or destroyed tree depends on the circumstances of the loss and the appropriate appraisal method. Factors may include the tree’s species, size, condition, location, function, marketability, extent of damage, and contribution to the property. A professional appraisal evaluates the specific facts rather than relying on a single universal formula.
Can you sue a neighbor for cutting down or damaging your tree?
Possibly. Whether a legal claim exists depends on tree ownership, property boundaries, what happened, the extent of the damage, applicable law, and the resulting loss. A consulting arborist can help document the damage, evaluate the tree, provide an independent appraisal, and explain the arboricultural issues involved in the dispute.
What evidence does an arborist expert witness examine in a tree case?
An arborist expert witness may examine the tree and site, photographs and videos, maintenance and inspection records, construction documents, property information, weather data, prior reports, correspondence, and other evidence relevant to the tree-related questions in the case. The evidence reviewed depends on the circumstances of the assignment.
Can an arborist determine whether a fallen tree was dangerous before it failed?
Sometimes. A consulting arborist may be able to determine whether a fallen tree had defects, decay, structural problems, root damage, or other conditions that increased the likelihood of failure before the incident. The strength of that opinion depends on the physical evidence, photographs, records, site conditions, maintenance history, and other available information.
