Canadian beaver

Habitat

Typically found in grasslands, forests, and vegetated habitats.

Range

Widely distributed across Europe (15 countries), North America (United States), and South America (Argentina, Chile).

Buellia ocellata is a crustose lichen with a pale grey to white areolate thallus bearing dark lecideine apothecia surrounded by a paler excipular ring. It inhabits exposed bark of old deciduous trees and smooth-barked conifers in temperate European woodlands. This lichen is sensitive to air quality changes and associated with veteran trees in ancient woodland.

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.
