Tree Appraisal & Timber Trespass


Trees and landscapes add real, discernible value to your property and that value is measurable by our Certified Arborists.

What is Tree Appraisal & Timber Trespass?

Our clients retain tree appraisals for vehicle accidents, neighbor disputes, insurance claims, and tax loss. ​A tree appraisal establishes a legally defensible, monetary value of your trees. This is very important, as a large, healthy, amenity tree in a front yard has the potential to be worth thousands of dollars. In Washington State, tree appraisals and timber trespass are often used interchangeably.

Peninsula Urban Forestry Arborists have specific training in defensible tree appraisals, tree forensics, expert testimony, depositions, mediation and arbitration. Our detailed tree forensics and appraisal reports have resulted in successful court outcomes for our clients.

A little more about tree appraisals:

Taken from the Guide for Plant Appraisal, 9th Edition: “The methods recommended for determining the monetary value of plants have been prepared by the Council of Tree and Landscape Appraisals. The appraisal process is a systematic procedure that encompasses analysis, data collection, and the application of method(s) to derive reasonable conclusions and recommendations.”

The Council of Tree & Landscape Appraisers is comprised and represented by the American Nursery and Landscape Association, the American Society of Consulting Arborists, the American Society of Landscape Architects, PLANET, Association of Consulting Foresters of America, International Society of Arboriculture, and the Tree Care Industry Association.

The Guide, authored by the CTLA is the U.S. industry standard in valuation of trees and landscapes; being widely accepted in the field of tree appraisals. The CTLA’s appraisal methodology: “Cost of Remedy” was utilized in the preparation of this report. Being an undeveloped lot, the Subject Trees relay little influence onto the real estate value, or living condition, including human and cultural value, of the property. Hence, the valuation of the trees is defined by the costs associated with reducing their potential for failure and restoration of landscape.
