Woodland is one of the major types of vegetation in Hong Kong. According to the International Biological Programme, the term "woodland" refers to "open or closed vegetation with the principal layer consisting of trees, these averaging over 5 m tall", while our government publication Land Utilization in Hong Kong (1968) defined it as "land with a continuous cover of shrubs and trees over 8 feet (2.4 m) in height with interlocking canopies, not being within afforested areas".
