Dear Station Members,
Attached is a set of recent news for the proposed tree planting in the western districts of HK Island.
ISA HK/China views the action to be full of good intention to plant trees to cool our city & to bring about the ecological & social benefits of trees to our community. On the other hand, the comments made by our prominent tree professional Prof CY Jim may also be valid in saying that Sophora japonica is a temperate species which would have survival problems in our summer, & Michelia alba would be too large & spreading for our narrow streets. The Camptotheca acuminata appeared to be a correct choice, since this tree is ex-current with predictable wind loading to minimize Structural Pruning & it is tough enough to survive our urban conditions.
It is recommended in ISA education that Right Trees should be planted in the Right Places. Proper tree selection will minimize future maintenance & failure, although Structural Pruning is always recommended after the 12 month Establishment Period & annual inspection should be given by an Independent Practicing Arborist for impartial comments on tree condition & risk. Trees are very much like humans & regular care must be given for them to stay healthy & lasting. Lack of care would neglect abuses from our city development with which our urban trees would not last long to provide the social & ecological benefits to give us.
It would be good if our public can be provided more fundamental education on trees, & this may make trees to be our asset rather than liability as some have seen it.
Can ISA HK/China help on this?
best regards,
Sammy Au
