Rupert’s Land was a vast territory of northern wilderness. It represented a third of what is now Canada. From 1670 to 1870, it was the exclusive commercial domain of the Hudson’s Bay Company(HBC) and the primary trapping grounds of the fur trade. The territory was named after Prince Rupert, the HBC’s first governor. Three years after Confederation, the Government of Canada acquired Rupert’s Land from the HBC for CAD$1.5-million (£300,000). It is the largest real estate transaction (by land area) in the country’s history. The purchase of Rupert’s Land transformed Canada geographically. It changed from a modest country in the northeast of the continent into an expansive one that reached across North America. Rupert’s Land was eventually divided among Quebec, Ontario, Manitoba, Saskatchewan, Alberta and the Northwest Territories.

Salamanders are tailed amphibians belonging to the order Caudata. There are around 800 known species worldwide; 22 are found in Canada. In addition to these species, the unisexual Ambystoma, a unique lineage of salamanders that does not conform to the typical definition of a species, are also found in Canada. Salamanders mainly live in the temperate regions of the Northern Hemisphere and tropical South and Central America. North America is home to more species of salamanders than anywhere else in the world. In Canada, salamanders are found from the Maritimes to British Columbia, and as far north as central Labrador and northern British Columbia; none have been recorded on the island of Newfoundland.

The Salish Woolly dog was an important part of Coast Salish life throughout southern Vancouver Island, the Strait of Georgia, and Washington State, as the dogs’ hair was used to weave clothing and blankets. Due to the increased presence of European settlers and their machine-spun sheep wool, the Salish Woolly dog population declined in the 1800s until its extinction around 1900.
