南Y島再次發生不尋常塌樹事件.現希望各方人士作出協助.
上月20日.南Y島大坪村再次發生塌樹事件.(藍色標誌地方)一棵巨大榕樹整株連根塌下.雖然當天懸掛了3號強風信號,以觀察所見.塌樹原因並不單只強風所造成.
1; 塌樹地點並非一個當風位置,而樹葉並不茂盛.所以,榕樹本身並未構成一個太阻風的屏障.而鄰近樹木也並未受強風嚴重破壞
2; 樹葉並不茂或代表榕樹本身已受蟲害,某病原體侵害了一段長時期.未被人察覺.而強風有如助燃一樣,加速問題產生.
3;而在塌樹地點附近約30米地方.(即地圖上,綠色標誌地方)在不久前也發生塌樹事件.

這近距離,連環塌樹事件上.很需要專業人事作出分析.研究當中可有共通處.歸納有關數據.研究塌樹成因.對地方樹木保育.進行系統性研究等.
