香港嘅樹木覆蓋主要喺郊野公園（約佔土地四成），但市區綠化同樣重要。發展局綠化、園境及樹木管理組（2010 年成立）統籌全港樹木管理；各部門（路政署、康文署、地政總署）負責各自範圍嘅樹木。
古樹名木名錄由發展局樹木辦管理，收錄直徑 1 米以上、或高度 25 米以上、或樹齡超過 100 年嘅樹木。呢啲樹木受特別保護，未經許可不得砍伐。
市區樹木面對嘅挑戰包括：生長空間有限、颱風損害、病蟲害（如褐根病）。2018 年超強颱風山竹令全港數以萬計樹木倒塌，暴露市區樹木管理嘅問題。
常見市區樹種包括細葉榕、鳳凰木、宮粉羊蹄甲、木棉、白蘭等。細葉榕係香港最常見嘅市區樹，喺舊區街道常見百年老榕。
樹木保育同城市發展經常衝突：新發展區嘅樹木保育、市區重建中嘅老樹保留，係持續嘅政策議題。發展局每年公布樹木風險管理報告。
本站只寫有官方來源嘅樹木政策同統計；個別樹木嘅位置同健康狀況以樹木辦名錄為準。
發展局每年公布古樹名木名錄的年度統計：總量、因颱風或病蟲害死亡或移除的數目、經評估後新增的古樹數，以及各部門（路政署、康文署、地政總署、房屋署等）的樹木查驗總數與風險評估分級。上述年度樹木管理統計有明確財政年度，目前未在本站逐項點算。
私家路、私人樓宇、私人會所或私營商場轄下的樹木，若未納入發展局古樹名木名錄或各部門的正式查驗報告，其位置、樹齡或健康狀況一概不引用非正式社區名單或社交媒體流傳的「社區古樹」資料，避免主觀偏差。
仍未收錄的官方硬數據（全部有明確年度）：① 發展局古樹名木名錄（ROA）總量、死亡/移除數、新增數、各部門查驗總數與風險評估分級按財政年度 ② 路政署、康文署、地政總署、房屋署等部門的樹木管理數量、移除數、新植數按區 ③ 發展局樹木風險管理報告各項統計（褐根病、颱風損毀等）④ 規劃署綠化地帶、綠化總綱圖的各區綠化面積按年變化。刻意留白：非正式社區古樹名單、社交媒體流傳樹木資料、未經 ROA 或查驗報告確認的私人土地樹木一律唔引用。

Hong Kong’s tree cover is concentrated in the country parks, but the urban forest is substantial. The Greening, Landscape and Tree Management Section of the Development Bureau (established 2010) coordinates tree management; departments including Highways, LCSD and Lands manage trees in their own areas.
The Register of Old and Valuable Trees is maintained by the Tree Management Office. It records trees of 100 years or older, or of particular value, which receive special protection and may not be felled without permission.
Urban trees face particular challenges: limited growing space, typhoon damage and pests such as brown root rot disease. Super Typhoon Mangkhut in 2018 felled tens of thousands of trees across the city, exposing weaknesses in urban tree management.
Common street trees include Chinese banyan (Ficus microcarpa), flame of the forest and kapok. The Chinese banyan is the city’s most familiar street tree, with century-old specimens in older districts.
Tree preservation often conflicts with development: retaining old trees in new development areas is a recurring policy issue. The Development Bureau publishes annual tree-risk management reports.
This site records only tree policy and statistics with official sources; individual tree locations and conditions follow the Tree Register.
The Development Bureau publishes yearly ROA statistics: the total number of entries in the Old and Valuable Trees register, the number removed owing to typhoon damage or pest infestation, the number of newly assessed additions, and the total inspections and risk gradings by department (HyD, LCSD, LandsD, HAD, etc.). These yearly tree-management statistics carry clear financial-year timestamps but are not yet tallied item by item here.
Trees under private roads, private buildings, private clubs or private estates are not included if they fall outside either the ROA or a formal departmental inspection report. Informal community lists or social-media “local heritage trees” are never cited for location, age or condition — to avoid subjective bias.
Official hard figures not yet recorded (all carry an explicit year): (1) Development Bureau ROA totals, removals, additions and department-level inspection counts with risk gradings by financial year; (2) HyD, LCSD, LandsD and HAD tree-management counts, removals and new plantings by district; (3) Development Bureau Tree Risk Management Report itemised statistics (brown root rot, typhoon damage, etc.); (4) PlanD green-belt and Greening Master Plan area changes by district year by year. Deliberately left blank: informal community “heritage tree” lists, social-media tree claims and private-land tree data not verified by either the ROA or an inspection report are deliberately not cited.
