Arborist Services

As an ISA Certified Arborist I offer the following:
Tree Risk Assessment: I will inspect and evaluate the trees in question and make recommendations based upon my findings. Mitigation of tree risk by pruning, whole tree removal, relocating infrastructure, closing off access and many other solutions will be explored. I will use proven scientific methodology and all applicable industry standards to evaluate your trees. I'm equipped to evaluate single trees all the way up to entire populations.

Tree Preservation/ Construction Damage Mitigation: Working alongside planners, architects, building contractors, developers and others is my forte'. One of my jobs is to open productive channels of communication with all the parties involved with your project. I will create easily deployable tree protection guidelines, conflict mitigation guidelines or whatever else is necessary to protect your trees. Follow-up site visitations are part of any comprehensive tree preservation plan. I'm here to ensure that your preservation goals are met and often times exceeded.

Earth Friendly IPM, Disease Diagnosis and Recommendations: Pest management is always foremost in combatting untimely mortality in our trees. A focus on overall plant health care (PHC), Earth friendly Integrated Pest Management, species specific biological processes of the tree and environmental conditions allow me to produce a focused suite of recommendations for protecting your trees.

Planting, Replanting and Tree Removal Mitigation: My tree plantings are done right the first time. I'm able to encourage vigorous root system establishment by taking into account site conditions, soil composition and proper rootball preparation. My tree removal mitigation plans are tailored to each project, are concise and easy to deploy. I'm more than happy to work alongside your landscaping company during a planting.

Tree Inventory and Mapping: I will create a visual reference for you noting tree location, trunk diameter and approximate canopy spread of each tree desired. The inventory can range from a few trees to a complete mapping of your forest.

Arborist Reports: From basic to detailed, my reports can be tailored to fit your project's specific needs and objectives. I use industry standard language that is compliant with all local and state requirements.

Pruning Specifications: I will write detailed and specific pruning specifications for one tree or many trees. All pruning specifications will comply with ANSI A300 Part 1 and Z133.1.

Fees - Work - Payment

My onsite services are billed at $85 per hour. The minimum charge for a site visit is 2 hours. Travel time is billed by the half hour at $40 per hour. It is charged both ways for site visits and projects more than 15 road miles from Newcastle, California. Keep in mind that travel times may vary according to road conditions and traffic. Report research and writing is $40 per hour. Discounts are available for folks 65 years or older. Other discounts may be available. Please ask.

The amount of time it takes to complete a visual tree assessment depends on the number of trees and the trees themselves — how big they are, what kind of condition they are in and what is required to perform a thorough assessment. At single-family homes, I can usually complete a standard visual assessment well within the 2 hour minimum. If the assessments are completed and time remains, let’s spend the remaining time on trees outside of your immediate concerns. When I schedule an appointment for consultation and tree assessments, I prefer that you are present and engage in the process with me.

Homeowners, builders and developers, HOA’s, condominium/apartment complex managers, home buyers, real estate agents, other Certified Arborists (usually for a second opinion). If you are not noted here, please email me. I can usually help.

Once in a while I may need to climb into the tree to inspect a branch, branch-to-trunk connection, cavity (or anything else that catches my eye) for rot, mechanical damage, structural integrity, etc. I will let you know why I think a climbing inspection is necessary and give you an estimate of the cost.

I accept payment by cash, money order or check, made to Thomas J. Davis, at the time of the inspection. I do not accept credit cards. I will provide an invoice by email upon completion of the work at the site. Billing for reports and incidentals will be on a separate invoice.


Arborists specialize in the care of individual trees. They are knowledgeable about the needs of trees, and are trained and equipped to provide proper care. Hiring an arborist is a decision that should not be taken lightly. Proper tree care is an investment that can lead to substantial returns. Well cared-for trees are attractive and can add considerable value to your property. Poorly maintained trees can be a significant liability. Pruning or removing trees, especially large trees, can be dangerous work. Tree work should be done only by those trained and equipped to work safely in trees.

"My project was construction of a new detached garage structure in Carnelian Bay. The garage foundation was placed for location very close to a few very large old growth pines which I wanted to preserve. If I could not preserve these trees, the garage project would be cancelled. JD not only designed the system to protect and irrigate the roots during construction, but he also was a key team member in determining the exact perimeter of the foundation, clearances from the root systems, permanent protection under ground for the root systems, and the boundaries of the paving area. He was always on-site as needed to work with the contractor and make sure the contractor and workers understood the priority I had placed on keeping these trees in place, alive and healthy. Now, almost two years later, the trees continue to thrive and I also have the new garage structure I wanted."
