Talk:Local extinction

message: I redirected extirpation to extinction a while ago.  I suggest, while not feeling particularly strongly about the matter, that doing so is a benefit to the reader.  The reasoning is not only that the article was basically a dictionary definition with a couple of U.S. wolf examples, but also that there is, in the end, not a lot to explore in the nature of extirpation that would be out of place at the extinction article, which provides a lot of context.  Reintroduction of species is the only issue that comes to mind that probably doesn't deserve a lot of space at extinction, and if someone wrote up a solid encyclopedic summary of the issue there, I'd say that would be the time to split out a new article devoted to extirpation.

message: Extinction means there are no more, anywhere, and no possibility of restoration.  In the situation where there are no more in some locality (for any arbitrary definition of local!) but there are some somewhere else, that's not extinction.
The article should explain this term for what it is: an emotional term expressing alarm, dismay, fear, nostalgia, paranoia, etc.  It's use contributes nothing to logical or scientific thought. Richard J Kinch (talk) 08:40, 5 October 2018 (UTC)
replies: text: I agree that the article would be better placed at "Extirpation" instead. Even as a section within "Extinct" would be better than the incorrectly formed subject title as it currently exists. Loopy30 (talk) 02:10, 19 October 2018 (UTC)

See discussion at Talk:List of mammals of South Australia, from which I will copy first the OED definition obtained by :
The Oxford English Dictionary, Second Edition, Volume V, Dvanda-Follis
p520 Extinct see Extinguish 
p603-606 Extirp  1. to root up (plants)  2. to root out, exterminate (a family, sect, or nation)
p603-606 Extirpate 1. to clear of stumps.  2. to pull or pluck out by the roots; to root up, destroy, or remove root and branch (a tree, plant)  3. to root out, exterminate, or completely destroy (a class, sect, or nation); to kill off, and render extinct (a species of animal or plant)  4. to root out, eradicate (an immaterial thing e.g. heresy, vice etc.)
p603-606 Extirpator one who, or that which, extirpates.
And second, a condensed version of one of my comments from that page:
Biological definitions:  extirpation is defined as meaning "local extinction" in these definitions: Encylopedia.com, Biology dictionary, and some North American usage: , , . However, Biology online gives definitions akin to standard English dictionary ones, and it does not it appear at all in The Oxford Dictionary of Biology (8th ed.). The latter defines Extinction as "The irreversible condition of a species or other group of organisms of having no living representatives in the wild, which follows the death of the last surviving individual of that species or group. Extinction may occur on a local or global level; it can result from various human activities, including the destruction of habitats or the overexploitation of species that are hunted or harvested as a resource...". (My italics.)
2015 paper by a group of scientists and academics in Oklahoma - see Concluding Remarks. "It is clear that use of extinction versus extirpation has changed over time and that the public has a different sense of what extinction means relative to how many conservation biologists use the term." 
IMO, we could add improved explanation to this article, citing the above paper, the general dictionary usage per the OED meanings, and the Oxford Dictionary of Biology, as the basis of preferring the term "local extinction" in Wikipedia, bearing in mind that Extirpation (+ related forms) redirect to this page, so it needs mention.

replies: text: many of the regional bird lists use the word extirpated rather than local extinction. Avibase and the American Ornithological Society use the term and our lists follow as they are the main references for the lists....Pvmoutside (talk) 14:35, 10 March 2021 (UTC)

text: Some others to add to Ddum5347's list of organisations which use "extirpation" rather than "local extinction" include: BirdLife International, the American Ornithological Society, the American Society of Mammalogists (they use both, actually, though "local extinction" only very rarely), and the Botanical Society of Britain and Ireland. Page 8 in the latter's newsletter has an interesting explanation of how the two differ. MeegsC (talk) 17:10, 10 March 2021 (UTC)

replies: text: Excellent links, . I also have another article that uses the word:  Ddum5347 (talk) 17:38, 10 March 2021 (UTC)
replies: text: I don't think the issue is how scientists use the word extirpation, or that it is in scientific literature a synonym (or even more correct terminology) for locally extinct (and btw I also noticed that it is tautologically expressed as "locally extirpated", or interchangeably used, within several articles), but what is in common usage for most of the Wikipedia readership. For me, the strongest arguments for using "local extinction" in favour of "extirpation" are (a) Table 3 in that article I posted, which shows the steep rise in the term "local extinction" towards 2000, at the same times as decline in the use of "extirpation", and secondly, the The Oxford Dictionary of Biology (8th ed.), which uses local extinction. And of course there's the current naming of this article. For the non-biologist (i.e. most of our readers), local extinction has a clearer meaning, is commonly used by news articles on the topic, and while it does no harm (and potentially provides further education) to provide both, using "extirpation" as a substitute with no additional explanation does more harm than good. This article could provide some of this discussion in a Terminology section. Looking at page views, this one hovers in the 400-600 range, while the Extirpation redirect range is 20-40.

text: Russian religious persecutions are likely also part of an ongoing Russian cultural genocide and ethnic cleansing campaign aimed at extirpating the idea of an independent Ukrainian nationality or Ukrainian Orthodox Church.
Here "extirpated" is meant to convey deliberate human action, whereas "locally extinct" is a neutral term that a species that previously existed in an area is now absent, without implying any particular cause or agency for the absence. Bahudhara (talk) 14:40, 17 April 2023 (UTC)
