Amenity trees provide physical, social and economic benefits to people sharing their environment. To maintain the benefits that many people have come to expect of trees in their urban landscapes, a viable and dynamic tree population is required. To this end it is necessary to plant new trees or replace existing trees when they require removal. The challenge when replacing mature trees is not simply the process of planting a tree when one is removed, but of the continual replacement of the entire tree population in a planned and managed fashion. In urban landscapes this is not a natural process, and human intervention is required.

Responses were compared with similar studies in Britain and Ireland. It found there were no uniform guidelines for determining a tree's function, status, health and safety or value, and no general risk identifying criteria by which trees can be managed. It proposes a draft tree management plan for use by local government to establish the number of trees that need to be managed, their condition, risk status and amenity value. It also contains recommendations about policy, strategies and performance criteria to guide management and operational staff.

Trees are a valuable asset of our society, but little policy research has been conducted in this area at the university level. The policy in Hong Kong has changed from tree preservation to tree management due to repeated tree collapse incidents that have affected public safety and the harmony and sustainability of the environment and society. The Kingdon and Zahariadis multiple streams approach is found to be the most suitable analytical framework for the analysis of tree management policy in Hong Kong. The problem stream looks at why the problems occur, what they are, the magnitude of change in the conditions and why we need to do something about tree management. The policy stream looks at how to deal with and regulate tree management. The politics stream looks at what is done by whom in tree management policy. Finally, the aforementioned three streams are coupled by policy entrepreneurs using policy output so that the agenda can be set and the policy adopted. The tree management policy in Hong Kong is investigated and analysed through the lens of multiple streams theory and it is hoped that the information in this dissertation can offer a clearer understanding of the policy and its role in creating a better Hong Kong. / published_or_final_version / Public Administration / Master / Master of Public Administration
