Notes

  • S1650 - 743 used a habitat suitability model and mean density¬† data to estimate a population of 2,679 + or - 350 (2,329-3,029 individuals). Lower limit of 304 retained until systematic survey data become available.
  • S6923 - The population has recently been estimated at 3,100 ? 396 (SE) individuals (Long et al.submitted) through the modelling of observed densities at suitable sites across an estimate of the total area of habitat above a defined suitability threshold (Long et al.2006). The standard error range is rounded to the nearest 100 and used as the population range estimate.
