A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species ...
The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. . Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmenta
As of July 2021, the IUCN lists 14,033 animal species and 6,635 plant species as least concern. [1] No least concern assessments have been made for taxa of other kingdoms. Lists: Animals (kingdom Animalia) Amphibians — List of least concern amphibians; Birds — List of least concern birds; Fish — List of least concern fishes; Invertebrates ...
The IUCN criteria are authoritative and should be used directly if applicable. Domesticated : no immediate threat to the survival of the species. [ dubious – discuss ] This category overlaps Least Concern but has been applied to domesticated animals, for which the IUCN criteria are not valid.
Diagram of Lower Risk / near threatened in the older IUCN version 2.3, beside the former Lower Risk / conservation dependent subcategory.. Before 2001, the IUCN used the version 2.3 Categories and Criteria to assign conservation status, which included a separate category for conservation-dependent species ("Conservation Dependent", LR/cd).
The IUCN has many ranks that define an animal's population and risk of extinction. [1] Species are classified into one of nine Red List Categories: Extinct, Extinct in the Wild, Critically Endangered, Endangered, Vulnerable, Near Threatened, Least Concern, Data Deficient, and Not Evaluated. [2]
Those species of "Near Threatened" (NT) and "Least Concern" (LC) status have been assessed and found to have relatively robust and healthy populations, though these may be in decline. Unlike their more general use elsewhere, the List uses the terms "endangered species" and "threatened species" with particular meanings: "Endangered" (EN) species ...
A reduction of at least 20%, projected or suspected to be met within the next ten years or three generations, whichever is the longer, based on (and specifying) any of (2), (3), (4) or (5) above. B) Extent of occurrence estimated to be less than 20,000 km 2 or area of occupancy estimated to be less than 2,000 km 2 , and estimates indicating any ...
