Habitat & Geographic Range

Canadian beaver

Habitat

Typically found in grasslands, forests, and vegetated habitats.

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

Chalcidoid wasp

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

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.

Chalcidoid wasp

The Chalcidoid wasp (Tetrastichus julis) is a species in the genus Tetrastichus. Typically found in virtually all terrestrial and freshwater habitats.
