Biostatus Information

Biostatus information for each taxon is provided for New Zealand, and other regions if they are listed.

The biostatus information is presented in two parts:

1. Occurrence records the presence of a taxon in the region. It uses the following categories:

  • Absent from region
    • Recorded in error: Indicates that a name has been used incorrectly for a taxon in the region.
    • Extinct: Indicates that a taxon no longer occurs in the region.
    • Eradicated: Indicates a taxon that has been deliberately removed from the region.
    • Intercepted at the border: Indicates that a taxon has only been intercepted at the border, and has never been released or established in the region.
  • Present in region
    • Present in wild: a taxon that has self-maintaining populations in the wild.
      • Exotic taxa in this category are termed “fully naturalised”.
    • Sometimes present in wild: a taxon that occurs only occasionally in the region, or has been collected infrequently from the wild, or persists in the wild only for a short period, or in the vicinity of cultivated/captive parents.
      • Exotic taxa in this category are termed “casual”.
      • Indigenous taxa in this category are sometimes termed “vagrant”.
    • Present in captivity/cultivation only.
  • Uncertain

2. Origin records whether a taxon is indigenous or exotic in the region. It has the categories:

  • Indigenous to region: a taxon that occurs naturally in the region.
    • Endemic: an indigenous taxon that occurs naturally only in the region.
    • Non-endemic: an indigenous taxon that occurs naturally in this and other regions
  • Exotic to region: a taxon that has been accidentally or deliberately introduced into the region.
  • Uncertain: a taxon for which the biostatus has not yet been determined or coded.
