Canadian beaver

The largest rodent in North America, Canadian beavers weigh up to 32 kg and are master ecosystem engineers inhabiting rivers, lakes, and wetlands across Canada and the northern United States. By felling trees and constructing dams up to hundreds of meters long, beavers create ponds that provide habitat for hundreds of species. Their lodges and canals transform entire watersheds. Once nearly hunted to extinction for their fur, beaver populations have recovered strongly.

Monarch

One of the world's most remarkable migratory insects, monarch butterflies undertake multigenerational round-trip migrations of up to 4,800 km between breeding grounds in northern North America and overwintering sites in Mexican mountain forests. Brilliant orange and black wings warn predators of toxicity derived from milkweed plants consumed as caterpillars. Endangered, with overwintering populations having declined by over 80% since the 1990s due to milkweed habitat loss, pesticides, and climate change.
