Current positional data for Poa litorosa and Carex trifida at Handspike Point area (Macquarie Island) were collected using Global Positioning System (GPS) equipment and standard observational techniques. Different techniques were employed, depending on available expertise and equipment. These techniques are described in detail below. Areas were free from overhead obstructions and therefore ideally ... suited to GPS data collection.
This mapping of the distribution of Poa litorosa and Carex trifida on Macquarie Island together with the mapping of Ranunculus crassipes described by the metadata record with ID ASAC_1015_HIGPS03_04 contributed to the paper:
