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).

Common Pond Frog

Habitat

Typically found in freshwater habitats, moist forests, and wetlands.

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.

Common Pond Frog

<em>Fejervarya vittigera</em>, the common pond frog, is a dicroglossid frog in the family Dicroglossidae, adapted to freshwater and wetland habitats including rice paddies, ponds, marshes, streams, and irrigated agricultural fields. It is typically a robust, medium-sized frog with a brown or olive-grey dorsum marked with longitudinal ridges and variable patterns, well suited for camouflage in its aquatic and semi-aquatic environments. The species is broadly distributed across South and Southeast Asia, favouring lowland areas with permanent or seasonal water availability. <em>Fejervarya vittigera</em> is carnivorous, typically feeding on invertebrates including insects, worms, and small crustaceans encountered near the water's edge or within aquatic vegetation. It is assessed as Least Concern on the IUCN Red List, with populations generally considered stable across its wide range, supported by its tolerance of modified habitats such as rice paddies. Biological traits such as average adult lifespan, precise body dimensions, body mass, and comprehensive dietary data across its geographic range remain poorly documented in the scientific literature. The species may face localised pressures from pesticide use in agricultural areas and habitat drainage.
