Abstract.
This paper introduced the past and current situation about distribution and population of wolf (Canis lupus) in different countries. Wolf once distributed widely in the world. Its distribution area has diminished greatly
as their living conditions are destroyed, together with persecution from humans. The overall population of wolf is
also declining. In some countries, wolves are endangered or even extinct. Now some countries have placed the
wolf on the national list of protected animals. Alaska of the United States and Canada are the widely distributed
areas of wolves in the world.
