Columbian Exchange - Introduced Feral Populations

Introduced Feral Populations

Escaped and feral populations of non-indigenous animals have thrived in both the Old and New Worlds, often displacing native species.

Gray squirrels have been particularly successful in colonising Great Britain and populations of raccoons can now be found in some regions of Germany, the Caucasus and Japan. Fur farm escapees such as coypu and American Mink have extensive populations in the Old World.

In the New World, populations of feral European cats, pigs, horses and cattle are common.

Famous quotes containing the words introduced and/or populations:

    I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.
    Henry David Thoreau (1817–1862)

    The populations of Pwllheli, Criccieth,
    Portmadoc, Borth, Tremadoc, Penrhyndeudraeth,
    Were all assembled. Criccieth’s mayor addressed them
    First in good Welsh and then in fluent English,
    Robert Graves (1895–1985)
