九龍塘古樹疑染病瀕死 (印度榕/印度橡樹Ficus elastica Roxb. ex Hornem.)

【明報專訊】康文署《古樹名木冊》內一棵印度橡樹懷疑感染俗稱「樹癌」的褐根病,有市民發現樹身長出真菌,樹木專家認為該樹健康於過去半年正急速走下坡,應已返魂乏術,但康文署的名冊顯示,上次檢查日期是去年10月5日,當時並沒註明該樹健康有問題。
樹身長真菌 樹根腐爛
有市民昨向本報指出,九龍塘丹桂路休憩花園內一棵古樹(編號LCSD SSP/14)健康轉差,樹身長出真菌,樹根腐爛,質疑政府未有好好護理。長春社總監蘇國賢看過本報昨拍攝的照片,指該樹可能感染褐根病,長出真菌,健康極差,康文署應評估是否有倒塌風險,決定是否移除。
蘇國賢說,該樹約40%樹葉面積較正常細小,但一向沒表面病徵,去年12月檢查該樹仍未見長出真菌,估計該樹的健康於過去半年迅速轉差。康文署昨回應稱,該署一直有監察該樹,並定期詳細檢查及護養。該署今年5月初檢查時,已發現該樹的樹葉稀疏,葉片萎黃,懷疑出現初步褐根病徵狀,但整體結構並無問題。康文署已即時安排進一步詳細檢測,以確定該樹是否患上褐根病,並會加強護理。

美國: 樹遭雷擊剝光皮面臨枯死

美國艾奧瓦州一間學院的一棵大樹,被雷電擊中,但並無變得焦黑,因為樹皮裂成兩半脫落,面臨枯死。

香港的古樹,到現在仍未有一棵加裝Tree Lightening Protection System,TMO的專家們,可否考慮一下?
