Notes

  • S5249 - Separation of SE and SW populations is not confirmed.
  • S8022 - Estimate recognises inadequacy of data for assessing the past decade and encompasses peak numbers from 1980s-1990s moderated by likely subsequent decline due to changes to habitat.
  • T6029 - Likely declines since 1990's due to changes to habitat.
