Source-derived summary

Local extinction refers to the complete disappearance of a species from a specified geographic area, region, or habitat while that species continues to survive in some other part of the world. Local extinctions are contrasted with global extinctions in which the species no longer lives anywhere worldwide.

Editorial summary

“Local extinction” enters the record as disappearance of a species from a specific area. Crown Archives preserves that source wording while asking what Local, extinction and Disappearance can confirm, complicate or overturn.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 47-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Local, extinction and Disappearance.
Editorial analysis

Why this record matters

“Local extinction” is worth following because a concise public description often conceals a longer documentary argument. Here, Local, extinction and Disappearance provides the most credible route into that argument.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 28, 2026.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
