Habitat & Geographic Range

Canadian beaver

Habitat

Typically found in grasslands, forests, and vegetated habitats.

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

Range

Found in Colombia.

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 Lesser Toad

<em>Rhinella granulosa</em>, commonly known as the common lesser toad, is a small amphibian belonging to the family Bufonidae. This species is native to Colombia and is typically found in freshwater ecosystems, moist tropical forests, and wetland habitats. It inhabits lowland and foothill environments where moisture is consistently available throughout the year. The common lesser toad is classified as Least Concern on the IUCN Red List, indicating that its populations are currently stable and not under significant threat. Like other members of the genus Rhinella, it is typically insectivorous, feeding on small invertebrates found in its humid forest floor environment. The species plays an important ecological role as both predator of insects and prey for larger animals within its native Colombian range. Its granular skin texture, referenced in its scientific name, provides some protection from predators. Population trends remain stable, and the species benefits from the relative abundance of suitable freshwater and forest habitats across its range in Colombia.
