00:04Canadian Wolves Cross Lake Superior to Save Isle Royale's Vanishing Pack
00:08Canadian Wolves Crossed Lake Superior to Rebuild a Vanished Island Pack
00:12On Isle Royale, forests, rocky shores, moose trails, and cold water surround one of America's
00:17most isolated national parks. By 2018, only two wolves remained on the island, leaving moose to
00:23browse young trees across the forest. Park crews began a relocation project, moving wild gray wolves
00:29from Minnesota, Michigan, and Ontario into the Lake Superior Wilderness. Crews placed wolves in travel
00:35crates, carried them by boat or aircraft, and released them with tracking collars on the island.
00:40Ontario wolves became a major part of the rescue, bringing fresh genes from Canada into the struggling
00:44island population. The project moved 19 wolves between 2018 and 2019, turning a collapsing pack
00:51into a working predator group again. Researchers now track wolf movements through radio collars,
00:56snow surveys, trail cameras, and signs left near moose kills. The revived wolves hunt moose through
01:01spruce forests, rocky ridges, wetlands, and frozen trails where people rarely walk. Moose numbers matter
01:08because hungry moose can strip young trees and change the shape of the island forest. The wolf revival
01:13shows one pattern. Sometimes a wild place needs outside help before silence takes over. When a collared
01:19wolf steps onto Isle Royale snow, one island's old predator story begins moving again.
