While most people recognize tree workers as the ones climbing trees and trimming branches, an arborist role is more analytical and strategic.

Even within the certified arborist community there are slight differences, one main difference is consulting arborists will use their expertise in situations where litigation or trials become necessary.  In addition to everything a certified arborist does, consulting arborists typically have the same base qualifications but extend their expertise into advanced diagnostics, legal analysis, reporting, and strategic planning. Many are Registered Consulting Arborists (RCA) through the American Society of Consulting Arborist (ASCA), a designation that involves rigorous training, testing, and adherence to strict ethical guidelines.

A consulting arborist provides expert advice and assessments related to trees, focusing on their health, safety, and preservation. They offer services like urban forest management, tree risk assessments, diagnostic testing, tree appraisals, and consultation on tree management for various projects, including construction and development, urban tree canopy assessments, and legal matters.

Why You Might Need a Consulting Arborist?

There are many situations where a consulting arborist’s services are not just helpful—they’re essential. Here are key examples:

1. Tree Inventories, Assessments, and Tree Surveys

“You can’t manage what you don’t know.”

Consulting arborists are experts in performing full tree inventories and assessment—whether for a municipality, school campus, corporate property, healthcare campus, or private residence. These inventories help clients:

• Understand species, condition, and maintenance needs of trees.
• Make informed management and budgeting decisions.
• Determine the environmental value of the tree canopy. (e.g., carbon sequestration, air purification, energy savings)

Tree surveys are slightly different from a full inventory, and are commonly required as part of the development process, and are required by cities before construction can start. Tree surveys help identify protected trees and are required in order to meet local mitigation requirements.  If tree surveys are not accurate it can significantly delay projects and increase costs. 

2. Developing and Implementing Tree Management Plans

A healthy tree canopy starts with a well-designed management plan. Consulting arborists develop comprehensive strategies and plans based on:

• Tree health data
• Site conditions
• Invasive pests and disease (such as Emerald Ash Borer & Oak Wilt)
• Client goals

They collaborate with landscape architects, urban planners, and property managers to ensure trees are preserved and maintained effectively.  Plans can include, but are not limited to; pruning schedules, tree health care, pest and disease management, irrigation guidance, and soil care practices tailored to the property.  Consulting arborists will work with clients to develop and oversee a variety of plans. 

3. Tree Conservation and Preservation During Construction

If trees are not taken into account during the planing phases of construction it can place immense stress on existing trees. Consulting arborists provide:

• Tree preservation plans tailored to specific projects
• Site inspections before, during, and after construction
• Protection strategies for roots, trunks, and canopies

Whether you’re remodeling, adding a pool, or starting a new build, involving a consulting arborist early helps protect your trees and avoid costly mistakes.  A well designed tree preservation plan will help ensure trees are well cared for during the construction process.

4. Tree Planting and Green Infrastructure Planning

Tree planting seems simple, but long-term success starts with choosing the right tree for the right place. Consulting arborists work closely with Landscape Architects, Engineers, and Planners on “right tree right place”, using trees as infrastructure for storm water retention, and proper tree planting procedures in urban areas. 

• Recommend species based on climate, soil, and space.
• Ensure proper placement to avoid future conflict with infrastructure.
• Proper planting procedures, including adequate soil volumes.
• Work with Engineers to introduce blue, green strategies.
• Guide long-term care to ensure survival and growth.

They also work to support community planting efforts and educate property owners and the public about the environmental and social benefits of a healthy tree canopy. For example a consulting arborist can assist a city, school, or medical facility to become designated as a Tree City USA.

5. Diagnosing Tree Health and Structural Issues

If your tree is declining, showing signs of disease, or was damaged in a storm, a consulting arborist can:

• Diagnose health issues like fungal infections, pest infestations, and decay
• Evaluate the structural integrity of trees (e.g., cracks, weak unions, root issues)
• Recommend targeted treatments or removal when necessary

Consulting arborists often use advanced tools such as resistographs, drones, and soil probes to thoroughly evaluate tree health beyond what’s visible.

6. Tree Appraisals 

Trees carry monetary, ecological, and aesthetic value. In cases of:

• Insurance claims
• Real estate transactions
• Legal disputes
• Damage or loss due to construction

Getting a professional appraisal by a consulting arborist provides an objective valuation using industry standards such as those outlined by the Council of Tree and Landscape Appraisers (CTLA). 

7. Legal Disputes and Expert Witness Services

When disputes arise over tree ownership, damage, removal, or encroachment, consulting arborists:

• Offer impartial analysis
• Provide written reports suitable for court cases
• Serve as expert witnesses in litigation

Their insights can make or break a legal case by providing science-backed evidence and interpretation.
