Wildest Islands is a documentary series that explores the wildlife on different islands or archipelagos around the world, showing all the diversity that they boast. The islands (Zanzibar, Caribbean, Galapagos, Sri Lanka, Hebrides) are in different oceans and conditions, and in them wildlife, human populations and geology often interact significantly with insular and/or continental neighbours.
This episode of the series deals with Vancouver Island, in British Columbia, Canada. Vancouver Island is a vast and wild island with mountains running its length. The largest island off the west coast of North America, its glaciers fuel the flow of some of Canada's tallest waterfalls and an endless network of rivers and creeks make it the ideal habitat for the Pacific salmon. Turkey vultures gather for the migration south as they head for warmer weather in winter.
