" The existing trees over 75mm in width calculated at 1.5m above soil level which are:
o Surrounded by the site;
o Pendant the site;
o Within a expanse of the limit of the site which is less than half the elevation of the tree; or
o Located on land adjoining to the expansion of the site that might manipulate the site or might be key as part of the local scenery character.
" Trees that are less than 75mm diameter at 1.5m above ground are not required to be surveyed with great detail but should be mentioned in the report.
" Existing buildings/structures that surrounds the trees and to which the trees surrounds. Their description and the nature of the survey depends on such description.

" And many other such info
The survey should study and list all the trees in the boundary of the tree survey activity. The group of trees should be particularly listed along with their reference number. In reviewing the amenity worth of trees, regard should be given to the three criteria
o Visibility- the visibility of the trees and plantations from the public view point like that from roads and foot path
o Size and form- the size of the trees that it should attain and it is in present, to assess its growth pattern
o Wider impact- the significance of the tree in their local and environmental conditions and how suitable they are for the development and environment protection.
