Register of Old and Valuable Trees
It is Government policy to provide priority protection to Old and Valuable Trees. The Leisure and Cultural Services Department, Agriculture, Fisheries and Conservation Department and Housing Department have identified some 500 Old and Valuable Trees on unleased Government land within built-up areas or tourist attractive spots in village areas. Built-up areas include both metro and new town areas but excluding country parks therein.
a) Tree of large size

Tree of particularly large size (i.e. either trunk diameter or height or canopy spread), taking into consideration the normal size of such species. In terms of size, the following standards were generally used -

  • Trunk diameter
    Trees with trunk diameter of or over 1 000 mm (measured at 1.3m above ground level).

  • Height
    Trees of or over 25m in height.

  • Canopy spread
    Trees with spread of or over 25m in diameter.
b) Tree of precious or rare species

The population of a species is in scarcity based on professional judgement and the number of tree species recorded in the inventories kept by Leisure and Cultural Services Department and Agriculture, Fisheries and Conservation Department.
c) Tree of particularly old age (e.g. over 100 years old)

The planting date of the tree had been traced as far as practicable to check whether its age was over 100 or not. If the planting date was not known, the tree was compared with other trees of the same species over 100 years old.
d) Tree of cultural, historical or memorable significance; and

A tree which was known to have cultural, historical or memorable significance. Examples of such are listed below: -

  • Cultural Significance
    Well-known Fung Shui or landmark tree (e.g. the Ficus microcarpa in Yau Ma Tei Community Centre Rest Garden (commonly refers as 'YUNG SHU TAU' by the locals)) or tree within known woodlands was considered where appropriate.

  • Historical Significance
    Landmark tree preferably with evidential records to support the historical significance of the trees falls under this category e.g. the Pterocarpus indicus outside the Central Government Office.

  • Memorable Significance
    Tree with special memory for it was planted by a senior government official, or local/foreign dignitaries and celebrities for commemorating special events was considered.
e) Trees of outstanding form

Tree bears an outstanding form for its aesthetic and landscape significance. Examples of such are: -
  • the Tree House in Shui Mei Tsuen Playground, Kam Tin;

  • the hollow tree at Lai Chi Wo;

  • trees with natural fusion of branches or with curtain like aerial roots; and

  • tree growing on old stone retaining walls and displaying a well-balanced form or curious growth form.
In addition, we have also assessed the conditions of the trees on the following aspects before registration -

a) Health and physical conditions

The health and physical conditions, such as the presence of any extensive cavities, cracks or diseases etc. or poor branch structure, which may endanger its structural stability or resulting in public safety hazards had been examined.

b) Life expectancy

If the tree would soon reach its end of life expectancy, it was excluded from the register.

c) Location

The importance of the tree in the landscape had been assessed with regard to the prominence of the tree in relation to the surrounding and the presence of environmental constraints. Factors such as very close to a building or blocking sightline of drivers were also considered.

d) Representative of its kind

The special features of the tree had been assessed and comparison with similar trees in the Register was also made to see whether such features were representative of its kind and whether the trees had any special scientific and ecological value.
