都市林危險樹木的檢查及診斷之標準程序建立

本計畫目前已完成檢查樹木共有42樹種合計1000株，未來將繼續累積不同樹木的案例，作為彙整樹木檢查的資料，已建立目視樹木外觀檢查危險缺點的項目，建立樹木危險及風險等級，建立提供減輕危害及改善樹木健全性的處置參考建議項目，建立預定的樹木健全性檢查實施方法及程序，將逐步修訂整個程序。配合樹木醫學教育學程上課共4次12小時，及樹木檢查示範記者會1場。已完成森氏紅淡比(6株)、台灣杉(14株)、紅檜(16株)等三種樹種生長輪的檢測，應用輔助人工專業樹輪辦識軟體來檢測年輪及評估樹齡。Currently, this project has completed the inspection of 1000 trees belonging to 42 tree species. In the future, we will continue to accumulate cases of different tree species to compile a comprehensive tree inspection database. We have established a checklist for identifying hazardous defects via visual tree appearance inspection, developed tree danger and risk rating systems, created reference recommendations for hazard mitigation and measures to enhance tree health, and formulated scheduled implementation methods and procedures for tree health inspection, which will be gradually revised over time. Additionally, this project has supported 4 teaching sessions totaling 12 hours for the arboriculture education program, as well as one press conference for tree inspection demonstrations. We have completed growth ring detection for three tree species: Adinandra formosana (6 specimens), Taiwania cryptomerioides (14 specimens), and Chamaecyparis formosensis (16 specimens), using an auxiliary professional artificial tree ring identification software to detect annual rings and evaluate tree ages.
