There are few long‐term studies of reintroduced populations. The aim of this study was to see if the population development of the reintroduced European beaver (Castor fiber) population in Sweden exhibits the same pattern of population development as other introductions, in accordance with general theories, and to discuss possible Cited by:   Local knowledge about a newly reintroduced, rapidly spreading species (Eurasian beaver) and perception of its impact on ecosystem services May PLoS ONE 15(5):e   At a larger scale, this study has shown that beaver reintroduction is part of a wider debate regarding Scottish landscapes and the possibility of reintroducing wild species in Scotland.

Such a debate is fuelled by a long history of conflict over land in Scotland, especially since the country has highly concentrated patterns of private ownership Cited by: 1.

Hundreds of millions of beavers used to populate the West but were hunted to near extinction. Turns out, beavers are critical to healthy water ecosystems, so.

merly native species. Beaver reintroduction is now being considered in Great Britain (GB) (distinct from the UK as there is no evidence of beaver residence in Northern Ireland (Halley & Rosell, )), with decision‐making devolved to the Scot-tish, English, and Welsh governments.

Since the midth century, reintroduction programs throughout Europe have led to the return of beavers in over 25 countries.

There is no evidence of past beavers in Northern Ireland. In Scotland, beaver populations are currently found in two areas. While in England, several reintroduction trials are taking place in both fenced and unfenced areas. The Beaver: A National Nuisance or Ecological Superhero. Introduction After viewing the Nature of Things documentary, The Beaver Whisperers, students learn more about the beaver and why scientists are starting to regard Canada’s national animal as an ecological superhero.

When the grey wolf was reintroduced into the Greater Yellowstone Ecosystem inthere was only one beaver colony in the park, said Doug Smith, a wildlife biologist in charge of the Yellowstone Wolf Project.

Today, the park is home to nine beaver colonies, with the promise of more to come, as the reintroduction of wolves continues to astonish biologists with a ripple of direct and. A five-year study into the reintroduction of beavers on the River Otter in Devon has been a “brilliant success”, ecologists have said and the government will now consult on further releases.

Research into the socio‐economics of beaver reintroduction, both potential costs and benefits, has been undertaken to some degree, noting particularly the socio‐economic reports on the Scottish Beaver Trial and Tayside Beaver population (Moran & Lewis, ; Scottish Natural Heritage,Tayside Beaver Study Group, a, b.

Documenting trends in Yellowstone’s beaver population: A comparison of aerial and ground surveys in the Yellowstone Lake Basin. Quantifying the aquatic ecological impact of beaver reintroduction is critical as the ecological status of many surface waters in the UK is poor and in need of restoration, having been degraded by multiple stressors over recent decades.

The reintroduction of the Eurasian beaver Castor fiber to Wales: an ecological feasibility study / Ail-gyflwyniad yr afanc Ewropeaidd Castor fiber i Gymru.

This is a landmark decision and one of the most important moments in England's conservation history. It's the first legally sanctioned reintroduction of an extinct native mammal to England. It means that the beaver population, which lives on the River Otter and is estimated to consist of up to 15 family groups, now has a secure future.

Once those trees were gone, a whole host of other animals left: birds, beaver, and fish that lived in the beaver ponds. The beaver dams broke and allowed water to flow through too fast to soak up in the surrounding landscape.

The land converted to grasslands and dry shrub-lands. Compared to its former glory, it was now a barren wasteland. Reintroduction as a guide. Reintroduction, the release of a species into an area in which it had been indigenous but has since become extinct, is a long-standing practice. The earliest use of the word reintroduction in a conservation context is in an article from about the return of capercaillie (or capercailzie) to Scotland (Wilson   In Scotland, a widespread positive influence on biodiversity is expected, if beavers are widely reintroduced.

For instance, beaver activity should provide important habitat for the otter Lutra lutra, great crested newt Triturus cristatus and water vole Arvicola amphibious, all species of conservation importance. Reintroduction of beaver (Castor spp) may facilitate rehabilitation of freshwater habitats providing a cost-effective sustainable means of improving ecological conditions.

Despite extensive research, debate and consultation, a general consensus on the impact of beaver on fishes has proven elusive because of variability in biological response.

Species reintroduction is the deliberate release of a species into the wild, from captivity or other areas where the organism is capable of survival.

The goal of species reintroduction is to establish a healthy, genetically diverse, self-sustaining population to an area where it has been extirpated, or to augment an existing population.

Species that may be eligible for reintroduction are. The reintroduction of the Eurasian beaver Castor fiber to Wales: an ecological feasibility study / Ail-gyflwyniad yr afanc Ewropeaidd Castor fiber i Gymru.
