MI_Azorella_dieback_5x5m
All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Description
This data set comprises data on Azorella macquariensis dieback from four summer seasons at a range of sites across Macquarie Island: 2008-09, 2009-10, 2010-11, 2011-12. Data on the proportion of healthy and dead or dying Azorella was collected from a 5 x 5m quadrat at each site. In some years data on the health of moss in the quadrats is also provided. The file is in the form of an Excel workbook with a separate worksheet for each year.
In addition there are photographs of the sites spanning up to 4 years 2008-09 to - 2011 -12. Most photographic suites contain a North West and a South East site photographs and most are within 5- 10 m of the GPS point for the site. The site codes identify the 5 x 5m quadrats.
Purpose
This paper is key supporting material for the analyses presented in the paper - Beyond the tipping point: collapse of a sub-Antarctic feldmark ecosystem. Lead authored by Dana Bergstrom and colleagues. Submitted in 2013.
