Local extinction, also extirpation, is the termination of a species (or other taxon) in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions. [1] [2] Local extinctions mark a change in the ecology of an area.

In ecology, extinction is sometimes used informally to refer to local extinction, in which a species ceases to exist in the chosen area of study, despite still existing elsewhere. Local extinctions may be made good by the reintroduction of individuals of that species taken from other locations; wolf reintroduction is an example
A 2022 report from NOAA predicts sea levels along U.S. coastlines will rise, on average, 10-12 inches through 2050.
Defaunation is the global, local, or functional extinction of animal populations or species from ecological communities. [4] The growth of the human population , combined with advances in harvesting technologies, has led to more intense and efficient exploitation of the environment. [ 5 ]
Southern sea otters along the West coast were hunted almost to extinction for their thick, soft fur, only gaining protection in 1913 when California declared them a "fully protected mammal." Even ...
The quasi-extinction threshold, or sometimes called the quasi-extinction risk is the population size below which a species is considered to be at extreme risk of quasi-extinction. [5] This threshold varies by species and is influenced by several factors, including reproductive rates, habitat requirements, and genetic diversity.
