Extirpation (in CC ambhib glossary)

[fishkeeper]

Definition of these two terms here.

 

[Kaysie]

Extinction: There are no living specimens of the animal available. Extinction may be total, or an animal may be 'extinct in the wild', meaning there are only zoo specimens available. Biological extinction is defined as animals continuing to exist, but with no viable production of young (Lonesome George: http://www.tortoisetrust.org/articles/george.html).

Extirpation: An animal no longer occurs in an area of its historic range.

 

[SludgeMunkey]

extinction: when an organism ceases to exist as a viable population

extirpation: when an organism no longer exists in its original ecosystem

 

[Jan]

Extirpation: Within the context of animals and plants, means the eradication of a species or subspecies from a portion of its natural range.

Eliminate 'extinct/extinction' from this thread as it is defined elsewhere in the glossary.
