A 2012 study of beavers' mark on the landscape found that cut stumps were negatively related to distance from beaver canals, but not to the central body of water. This finding suggested that beavers may consider the canals to be part of their "central place" as far as foraging activity is concerned. [69]
Beavers can be found in a number of freshwater habitats, such as rivers, streams, lakes and ponds. They are herbivorous, consuming tree bark, aquatic plants, grasses and sedges. Beavers build dams and lodges using tree branches, vegetation, rocks and mud; they chew down trees for building material. Dams restrict water flow, and lodges serve as ...
Due to official reintroductions since 1988, beavers are now found in most parts of the country, in particular the south, centre and north-west. [37] The population was around 3500 in 2019. [23] In Belgium the beaver was extirpated in 1848. Current populations are descendants of animals released in the Ardennes in 1998–2000 and in Flanders in ...

The Tule River Indian Tribe and state wildlife crews reintroduced nine beavers to their natural habitat in the Sierra. Beavers, back on tribal land after 100 years, could aid California's fragile ...
In contrast, the most often cited negative impact of beavers on fishes were barriers to migration, although that conclusion was based on scientific data only 22% of the time. They also found that when beaver dams do present barriers, these are generally short-lived, as the dams are overtopped, blown out, or circumvented by storm surges. [37]
These conditions were found to be met on 23 March 2015, following the capture and testing of five of the beavers. [44] DNA testing showed that the animals were the once-native Eurasian beaver, and none of the beavers was found to be infected with Echinococcus multilocularis , tularaemia , or bovine TB .
The parachuting beavers have become an Idaho icon, and the project represents a pivotal shift in how the animals were managed, experts said. It’s been 75 years since Idaho parachuted beavers ...
