Notes

  • S8608 - Fragmented population, only low numbers assumed from any site.
  • T6602 - Fragmented population, habitat loss in many areas
  • S9121 - Fragmented population, only low numbers assumed from any site.
  • T7181 - Dodman (2014) assumed decline based on fragmented population and habitat loss in many areas. ADU (2017) data confirms that that the species was absent in 16 quarter degree grid cells in SABAP2 where it was present during SABAP1, declined in one and occupied only 5 new ones.
