JPA provides plant valuation and casualty loss appraisals following industry guidelines and methods defined in the latest version of The Guide for Plant Appraisal authored by the Council of Tree and Landscape Appraisers and published by the International Society of Arboriculture.


James was instrumental in forming the American Society of Consulting Arborists (ASCA) Appraisal Advisory Group (A3G) in 2008.
