The assessment of the persistence of human impacts (field party disturbances) in the Asgard Range, Barwick Valley (both sites disturbed 30 years prior) and at Marble Point (disturbed up to 5 years prior)

The assessment of the persistence of human impacts was made by examining sites that had been disturbed by field parties up to thirty years previous in the Asgard Range (6 sites) and Barwick Valley (9 sites) both sites disturbed 30 years prior and at Marble Point (23 sites) disturbed up to 5 years prior. A number of other sites disturbed by other investigators in subsequent years were also found and observed.
