The technique of attribute listing is one of the most important techniques used during heritage impact assessment. Attributes can be of three types namely physical attributes, spatial attributes, and intangible attributes.

One of the functions of attribute listing includes helping determine the characteristics which make heritage sites important. The process of measuring the impact would become hard without identifying the attributes.

In addition, attribute listing plays a significant role in conservation planning by facilitating decision making processes.

It also aids in risk identification and facilitates communication among stakeholders like planners, conservationists, and regulatory bodies.

In summary, attribute listing is critical in the identification and management of heritage values.
