Certified Arborist Practice Exam 2025 – 400 Free Practice Questions to Pass the Exam

Arborists should ideally get involved in the initial planning stage of a construction project. This early involvement allows for the identification of existing trees that may be affected by construction activities, as well as the incorporation of tree conservation strategies into the design. Engaging an arborist from the beginning ensures that decisions are made with an understanding of the potential impact on tree health and the overall landscape, ultimately fostering more sustainable development practices.

While involvement during construction and after completion can be beneficial—such as monitoring tree health during the building process or reassessing tree conditions years later—these stages do not capture the proactive approach needed to preserve trees before construction starts. The choice suggesting involvement 3-5 years after completion would not address the immediate needs and considerations related to tree health during the planning and implementation phases of the construction project.
