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 ...
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 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
The term Least concern reflects the fact that this risk is relatively low. In practice this category is reserved for ecosystems that unambiguously meet none of the quantitative criteria (decline in distribution, restricted distribution, degradation of environmental conditions or disruption of biotic processes and interactions).
The IUCN also lists 131 subspecies and 118 varieties as least concern. No subpopulations of plants have been evaluated by the IUCN. This is a complete list of least concern plant species, subspecies and varieties evaluated by the IUCN.
LC (Least Concern) The Red List Index ( RLI ), based on the IUCN Red List of Threatened Species, is an indicator of the changing state of global biodiversity . It defines the conservation status of major species groups, and measures trends in extinction risk over time.
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.
The IUCN also lists 244 subspecies and 235 varieties as Vulnerable. No subpopulations of plants have been evaluated by the IUCN. For a species to be assessed as vulnerable to extinction the best available evidence must meet quantitative criteria set by the IUCN designed to reflect "a high risk of extinction in the wild".
