In 1940 twenty Canadian Beavers were brought to 'Tierra del Fuego' island in southern Patagonia for commercial fur production. However, beavers having no natural predators, quickly spread throughout the island, causing massive destruction of trees threatening the entire Patagonian forests rivers and species. Why wildlife conservationist are convinced that 150.000 beavers must be killed? Why some of the most recognized specialist are convinced that an eradication is not possible? Meanwhile truism is capitalizing on the situation: a man dressed as a beaver passes out flyers promoting a famous sky resort: 'Cerro Castor' - Beaver Hill. Hunters claim for subsidies, scientists are researching, rangers do what they can and restaurants tray to offer beaver meat to tourist.

Five scientists and a hairdresser, tackling climate change, one stick at a time.

We get to know a few inhabitants of central European rivers.

From PBS - The fascinating story of beavers in North America - their history, their near extinction, and their current comeback, as a growing number of scientists, conservationists and grass-roots environmentalists have come to regard beavers as overlooked tools when it comes to reversing the disastrous effects of global warming and world-wide water shortages. Once valued for their fur or hunted as pests, these industrious rodents are seen in a new light through the eyes of this novel assembly of beaver enthusiasts and "employers" who reveal the ways in which the presence of beavers can transform and revive landscapes. Using their skills as natural builders and brilliant hydro-engineers, beavers are being recruited to accomplish everything from re-establishing water sources in bone-dry deserts to supporting whole communities of wildlife drawn to the revitalizing aquatic ecosystems their ponds provide.

Documentary that details the daily habits of beavers and their interaction with the ecosystem at large. Filmed mostly in Digby County, Nova Scotia.

The film depicts a young male beaver who must defend his new family against hungry predators, mischievous river otters, and the ever-impending threat of winter.

Landscapes of drained marshes and reclaimed meadows, from where scientists from the Experimental Station of the Polish Academy of Sciences in Popielno relocate beavers to forest wetlands, secluded lakes, and rivers essential for the beavers' survival. With the film camera, we participate in this operation of capturing and transporting the animals, observing their first steps in the new environment, which they begin to organize for their needs. They fell trees they have gnawed, build dams, and create water expanses.

What could the bison and the beaver have in common? Although they are two completely different species in appearance, they have one remarkable thing in common: they create habitats that support the emergence and development of other animal and plant species. The bison and the beaver disappeared from Romania more than 200 years ago, and considerable efforts are now being made to reintroduce them back into the wild. This film tells the story of these two nature architects and talks about the many connections between these animals, their environment and the benefits to humans.

An expedition decided to observe the life of the beavers - nature's engineer - in the woods of the Rocky Mountains: for the first time a beaver family was filmed in its den during the course of the season.

Robi Watkinson and Emma Hodson travel across Britain and the Netherlands documenting the story of the rewilding movement from its inception, to the return of the beaver, bison and perhaps one day, the lynx to Britain.

This lively satire uses animation and a pseudo-documentary style to depict Canada's search for a national identity. The National Scream explains, amongst other elements of Canadiana, how and why the beaver became the country's symbol.

In the lush green town of Pushchino, scientific plans to establish a nature reserve meet opposition from industry.
