Habitat & Geographic Range

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).

Pien

Habitat

Typically found in temperate and boreal forests, often at higher elevations.

Range

Distributed across Australia, India, Libya, and South Africa.

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.

Pien

<em>Araucaria cunninghamii</em>, the colonial pine or hoop pine, is a large coniferous tree in the ancient family Araucariaceae, native to Australia and also cultivated or naturalised in India, Libya, and South Africa. This species inhabits temperate and boreal forests at higher elevations, where it often forms a prominent emergent layer in subtropical and tropical rainforest communities in Queensland and New Guinea. Hoop pine is one of Australia's most commercially important softwood timber species, valued for its straight grain, durability, and workability. Trees can grow to considerable heights, with tall trunks characterised by horizontally spreading branch whorls that give the species a distinctive silhouette. <em>Araucaria cunninghamii</em> is assessed as Least Concern by the IUCN. The genus <em>Araucaria</em> has ancient origins, with fossil records extending to the Jurassic period, making it a living relic of Gondwanan flora. Seeds of hoop pine are consumed by birds and other fauna in its native range, contributing to limited seed dispersal. Biological traits of this species remain poorly documented in the scientific literature.
