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 Globe-Thistle

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Range

Widely distributed across Europe (19 countries), North America (Canada, United States), and Oceania and the Pacific (Australia).

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 Globe-Thistle

<em>Echinops sphaerocephalus</em>, commonly known as the common globe-thistle or great globe-thistle, is a perennial herbaceous plant in the family Asteraceae. The species has a distribution spanning Europe, North America, and Oceania, with naturalization in several regions outside its native southern and central European range. <em>Echinops sphaerocephalus</em> typically inhabits dry, open, and disturbed habitats including roadsides, waste ground, rocky slopes, and steppe grasslands, where it is well adapted to poor, well-drained soils. It produces distinctive spherical, steel-blue flower heads that are highly attractive to pollinators, particularly bees and butterflies, making it a valued plant in native garden planting and ecological restoration. The species is not currently evaluated for conservation status. Biological traits of this species remain poorly documented in the scientific literature. <em>Echinops sphaerocephalus</em> is a robust, spiny plant that can grow to considerable height and spreads readily in suitable open habitats. Its ornamental qualities and pollinator value have contributed to its deliberate planting in gardens and public green spaces beyond its native range.
