Notes

  • T5724 - Fox et al. 2010. Trend 1960-2009: +2.6% p.a.; Trend 1995-2009: +1.0% p.a. Mitchell et al. 2010: Low point of 73,100 reached in 2003, since when numbers have increased again. Northward shift in range and mixing with other populations complicates the picture.
  • T2685 - 876. Trend 1960-2009: +2.6% p.a.; Trend 1995-2009: +1.0% p.a. 904: Low point of 73,100 reached in 2003, since when numbers have increased again. Northward shift in range and mixing with other populations complicates the picture.
  • S8257 - Rounded average for the period of 2009-2013. 5-year minimum: 88,577 individuals in 2013, 5-year maximum: 119,915 individuals in 2011 (Mitchell, 2014).
  • T6258 - Although decreased in 2013 and 2012, the overall trend is still increasing.
  • S8880 - Five-year-mean for 2007-2016.
  • T6890 - -1.5% p.a. calculated based on WWT (2017).
  • S9176 - Five-year-mean for 2007-2016, rounded to two significant digits. Minimum: 58,426 individuals, maximum: 95,403.
  • T7258 - Based on the data from WWT (2020), the population has decreased at a rate of 6% annually since 2010. The population size in 2019/2020 was 30% smaller than in 2010/11, which means that the population is in rapid short-term decline.
