Range

Widely distributed across Europe (8 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 Marsh Bedstraw

<em>Galium palustre</em>, the common marsh bedstraw, is a scrambling herbaceous plant in the family Rubiaceae, distributed across Europe, North America, and Oceania. It is classified as Least Concern on the IUCN Red List. This species typically grows in wetland habitats including fens, marshes, wet meadows, ditches, and the margins of rivers and ponds, where it climbs through taller vegetation using tiny hooked bristles on its stems and leaves. Common marsh bedstraw produces small, white, four-petalled flowers in loose clusters during summer months. Like other members of the genus Galium, its stems are distinctively square in cross-section. The plant plays a modest role in wetland ecosystems, providing cover for invertebrates and contributing to the structural complexity of marginal vegetation. Its widespread distribution across three continents and tolerance for a range of wetland conditions contribute to its secure conservation status. The species has limited documented economic uses but is ecologically representative of healthy freshwater marginal habitats.
