(b) of high cultural heritage value to the community or cultural group, including trees associated with aboriginal heritage and culture or
(c) associated with a heritage nominated place and representative of that same historic period.

(b) represents an outstanding example of the species, including age, size or habit or
(c) is an exceptional example of a native local species that reached maturity prior to urban development in its immediate vicinity.
Trees with scientific value are of particular importance to the community due to their ecological, genetic or botanical significance or ability to substantially contribute to the scientific body of knowledge and understanding. A tree may be considered to be of scientific value when it:
(a) is evidence of the former range limits or extent of the species or an ecological community or
(b) is an endangered or vulnerable species that is endemic to the Territory or local region now reduced in range or abundance or
(c) demonstrates a likelihood of providing information which will contribute significantly to a wider understanding of natural history by virtue of its use as a research site, teaching site, type locality or benchmark site or
(d) is of botanical or genetic value and is not well represented elsewhere in the Territory or is a significant habitat element for a threatened native species.
The Conservator may include a tree on the register under section 52 of the Act if it is located on built-up urban area and it can be demonstrated that it contributes to one or more of the values above when considered in the context of, and included with, other trees in its immediate vicinity.
