Entry ID:

Summary
Abstract:
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.
