Summary

Abstract: Samples from Macquarie Island were collected between 1998 and 2004. Samples from Heard Island were collected during 2000. Continental samples were collected between 2004 and 2006. This project aims to confirm that viruses are the cause of disease symptoms observed in several plant species from Macquarie Island, and to characterise the viruses. These would be the first examples of terrestrial ...

Quality The spatial quality of the dataset is poor. Site locations are poorly described, and would be difficult to replicate.

Dates provided in temporal coverage (1999-2004) are approximate only.

Taken from the 2008-2009 Progress Report:

Field work:
Fieldwork on Macquarie ... Island was very successful, during the short time available during resupply voyage 5. Dr M. Skotnicki revisted sites near Pyramd Peak, Green Gorge, Red River, Prion Lake, Bauer Bay, Island Lake, Scoble Lake and Razorback to reassess and rephotograph ecosystems, to collect specimens for genetic and viral/fungal disease analysis, and to monitor rabbit damage as part of a long-term analysis of vegetation responses in conjuction with plant disease and climate change.

Fieldwork was in line with the aims and timeframe of the project. All samples were obtained in accordance with permit requirements, and impacts on the plants and their habitats were minimal and transitory.

Laboratory activity/analysis:
Less experimental labwork has been done his year than originally anticipated, due to lack of funding. However, overall progress has been good, with more fieldwork components to the project being productive.

Difficulties affecting project:
Progress with experimental work was temporarily slowed this year by the time spent on ensuring compliance with new AQIS regulations, and by the lack of funding for lab work.
Rabbit damage - destruction of plants previously being monitored - is currently hampering progress with some objectives. However, once rabbits are eradicated, it will be much more feasible to assess whether regenerating plants and new seedlings are virus-infected - demonstrating whether or not virus infection is seed-transmitted.

Taken from the 2009-2010 Progress Report:

Field work:
Fieldwork on Macquarie Island was successful during six weeks in summer from December 2009 - January 2010. Dr A. Skotnicki, accompanied by Mr M. Duering, visited sites near Waterfall Bay, Pyramid Peak, Green Gorge, Red River, Bauer Bay, Island Lake, Scoble Lake, Razorback to reassess and rephotograph ecosystems, to collect specimens for genetic and viral/fungal disease analysis, and to monitor rabbit damage as part of a long-term analysis of vegetation responses in conjunction with plant disease and climate change.
