Another herd of wood bison from Alberta's Elk Island National Park will be roaming in Russia as part of an international conservation project.

Federal Environment Minister Peter Kent says 30 of the animals were transferred from the Alberta park, which is east of Edmonton, to the Republic of Sakha last week.

It's the third time bison from Elk Island have been sent to the Lensky Stolby Nature Park. Previous tranfers occurred in 2006 and 2011, and about 120 of the animals now make their home there.

Russian officials were in Canada to observe the selection and preparation of the bison, which were flown out from Edmonton International Airport on March 21.
