The Tatshenshini-Alsek Park in British Columbia, Canada, was established in 1993 after an intensive campaign by Canadian and American conservation organizations to halt mining exploration and development and protect the region for its strong natural heritage and biodiversity values.

In July and August 2007, after my trip to Ivvavik, I explored this park, located where the boundaries of Yukon, British Columbia and Alaska converge.

For several weeks, on foot and by canoe, I searched for the grizzly bears, the black bears and the moose in the Tatshenshini river area.

The Tatshenshini river begins in northwestern British Columbia and flows nearly 200km through the traditional territory of the "Champagne" and "Aishihik" First Nations into the Gulf of Alaska.

The Tatshenshini river region is one of Canada's most significant ecological area providing vital habitat for more than 50 species of mammals, including the world's densest population of grizzly bears. It is an important waterfowl migration route, providing rich habitat for more than 40 species of birds and spawning areas for salmon.
