From the abstract of the referenced paper: Buildings were constructed and artefacts left behind on sub-Antarctic Heard Island, associated with Antarctic research expeditions since 1926. Both bryophytes and vascular plants are colonising many parts of the now derelict buildings. On these structures and artefacts, the authors recorded four species of vascular plants out of the 11 that occur on Heard Island and nine species of mosses out of the 37 recorded from Heard Island. The vascular plants species most frequently recorded colonising structures and aretefacts was Pringlea antiscorbutica (288 occurrences), with the area colonised varying from 0.3 cm squared to 430.0 cm squared. Mueleriella crassifolia was the moss species that was most frequently recorded (14 occurrences), colonising areas from 2.1 cm squared to 12.9 cm squared. The highest number of bryophyte species (seven) was recorded on the stone and cement of the 'water tank'. Pringlea antiscorbutica, Poa cookii, Azorella selago, Muelleriella crassifolia, Bryum dichotomum, Dicranoweisia brevipes and Schistidium apocarpum are all expected to continue to colonise the ANARE ruins, as well as areas that have become available since building removal and also possible areas bared by further degradation. This work was completed as part of ASAC project 1187 (ASAC_1187). Data from this experiment are stored in an excel spreadsheet in csv format. The fields in this dataset are: Species Stem length (mm) Building Date built (year) Growth rate (mm per year)
