More than 150 translocations have now been undertaken across Europe, most without the detailed monitoring carried out by the Scottish Beaver Trial and other British projects, but some have been thoroughly studied, enabling scientists to predict with confidence the likely pattern of events post reintroduction. The size of these ponds and wetlands can be restricted by the use of flow devices where pipes set the maximum height of the dam, and thus the area of land flooded. Beavers are a much more recent addition to the South American ecosystemthe continents native trees have not developed the same defenses. Feasibility studies have been undertaken in Wales and these studies have determined that there is abundant habitat within Wales suitable for beavers, and thata beaver reintroduction to Waleswould beecologically feasible. He lives in Ushuaia, where beavers have previously gnawed through fiber optic cables, leaving the city without internet or cellular service.
