Don't know if we get the show in Alberta. Have to check.

Winters too cold? The first Russian wild boars were brought to New Hampshire in 1890. They are widespread in Europe, including the Carapathian mountains.
Wild boar was brought to the island of Hawai'i and licensed hunting is allowed on Moana Loa. They can be dangerous, and hikers are warned to be careful. There are a few in New Hampshire and Texas.
The small Asian pig is feral on Molokai and probablly the other islands, brought by the Polynesians.

Feeral Hogs occur in 39 states and 4 Canadian Provinces. Texas has some 2 million. Coyotes eat piglets and exercise some control. Escaped releases of the wild boar have interbred with feral pigs.
