In 2011, a Eurasian beaver pair was introduced to a beaver project site in West Devon, consisting of a 4.4 acres (1.8 ha) large enclosure with a 600 feet (183 m) long channel and one pond. Within five years, the pair created a complex wetland with an extensive network of channels, 13 ponds and dams.
Beavers in some areas will dig canals connected to their ponds. The canals fill with groundwater and give beavers access and easier transport of resources, as well as allow them to escape predators. These canals can stretch up to 1 m (3 ft 3 in) wide, 0.5 m (1 ft 8 in) deep, and over 0.5 km (0.3 mi) long.
Eurasian beaver and kit by the River Tay in Scotland. After being extinct for several centuries, beavers were reintroduced to Great Britain in 2009. The Eurasian beaver has been the successful subject of a century of official and unapproved species reintroduction programs in Europe and Asia.
As nearly 40% of the country is currently in drought, scientists are looking to the largest rodent in North America for help: the beaver.Researchers in California and Utah found that dams made by ...
The European species is slightly larger on average but the American has a larger known maximum size. Adults usually weigh from 11 to 32 kg (24 to 71 lb), with 20 kg (44 lb) being typical. In New York, the average weight of adult male beavers was 18.9 kg (42 lb), while non-native females in Finland averaged 18.1 kg (40
Beavers create unburned islands where plants and animals can shelter from megafires, research has confirmed. A movement is afoot to reintroduce the rodents to the state's waterways.
The Eurasian beaver (Castor fiber) or European beaver is a species of beaver widespread across Eurasia, with a rapidly increasing population of at least 1.5 million in 2020. The Eurasian beaver was hunted to near-extinction for both its fur and castoreum , with only about 1,200 beavers in eight relict populations from France to Mongolia in the ...
Beavers hold a very specific biological niche in the ecosystem: constructing dams across river systems. Niche construction is the ecological process by which an organism alters its own (or another species') local environment. These alterations can be a physical change to the organism’s environment, or it can encompass the active movement of ...
