Blue-spotted Salamander
Regional Extinction
This winter annual is no longer found in New York State. While this specimen was collected right here in Buffalo in 1890, it has since become regionally extinct. Extirpation, also known as regional extinction, is when a species no longer exists within a specific geographic region. Unlike extinction, extirpation means that a population persists in another area. The Museum’s herbarium houses thousands of pressed plant specimens, these document the flora of a specific region at a point in time. By studying a museum’s collection, you can determine how a landscape has changed over time.
