Notes

  • S6707 - Substantial rate and period of decline, well documented across flyway. WPE5 estimate is much lower than for WPE4 and accounts for loss (in NE Asia) of one of the population's most important staging areas. Ongoing comprehensive analysis by University of Queensland is anticipated to shortly provide a further reassessment.
  • T4188 - Substantial rate and period of decline, well documented across flyway.
