The replacement in North America of a ...

In North Dakota, by 1875 sightings of the wolf became rare, by 1887 they were almost gone. [6] On the Canadian Prairies, bounty payments for wolves commenced in 1878 in Manitoba, and 1899 in Saskatchewan and Alberta. [20] In North Dakota, two were sighted in 1915 by Remington Kellogg. The last known wolf was shot in 1922. [6]
