The distribution of all seven indicator species has continued to decline since the 1970s
- The distribution of kōkako and mōhua (yellowhead) has declined markedly since the 1970s.
- Four species – the short-tailed bat; dactylanthus (a flowering plant); and two bird species, the mōhua (yellowhead) and kōkako – are now found in only 5 percent or less of their pre-human range.
- Changes to the distribution of these seven species, in the total hectares each species can be found in, can indicate changes to ecosystems or the presence of pest species.
