Seminar/Webinar: Tree Appraisal - What Is a Tree Worth? 樹木估價 - 樹木價值為何?

Updated: Jan 12, 2023

We all know trees have value. But how much are they worth? Tree Appraisal is a new concept to most of the arborists in Hong Kong but it has been used in Australia, Europe, North America and other foreign regions for decades, applying to unexpected losses, tort claims, insurance claims, real estate assessment or proactive planning.

This time Mike Leung, former President of ISA Hong Kong Chapter and ISA Board Certified Master Arborist, will share the importance of Tree Appraisal in different circumstances and will briefly introduce different tree value calculation approaches including the most popular “Trunk Formula” illustrated in the “Guide for Plant Appraisal 10th Edition”.


這次我們將邀請前國際樹木學會香港分部會長兼國際樹木學會註冊資深樹藝師梁永強先生分享樹木估價應用於不同場景的重要性,並將介紹計算樹木價值的不同方法,包括於「Guide for Plant Appraisal 10th Edition」中最常提到的「Trunk Formula」。
