[2] [6] The Green Status complements the Red List assessment but does not replace it: both assessments are performed by the IUCN for a given species and, with the exception of species extinct in the wild that would require reintroduction as a conservation measure and whose current Green Score is by definition 0%, one status does not determine ...
The Green Status focuses on recovery of populations to their original roles, and is complementary to the avoidance of species extinction measured by Red Status. Grace's research involves measures to objectively assess these outcomes across different world habitats.

An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. [1] As of 2021, of the 120,372 species currently tracked by the IUCN, there are 8,404 species that are considered to be critically ...
As of December 2019, the International Union for Conservation of Nature (IUCN) has evaluated the conservation status of 280 fungus species. [1] Previously in the 2017-3 release, the IUCN evaluated the conservation status of 56 fungus species. [2] One subspecies, that of Pleurotus nebrodensis, also was evaluated but has since been removed. At ...
A visualization of the categories in the no-longer used "IUCN 1994 Categories & Criteria (version 2.3)", with conservation dependent (LR/cd) highlighted. The category was folded into the near threatened (NT) category in the 2001 revision, but some species which have not been re-evaluated retain the assessment.
