During drought years, where beavers were present, 60% more open water was available than those same areas during previous drought periods when beavers were absent. The authors concluded that beavers have a dramatic influence on the creation and maintenance of wetlands even during extreme drought.
Dams can range in height from 20 cm (7.9 in) to 3 m (9.8 ft) and can stretch from 0.3 m (1 ft 0 in) to several hundred meters long. Beaver dams are more effective in trapping and slowly leaking water than man-made concrete dams. Lake-dwelling beavers do not need to build dams. [59] Open-water beaver lodge in Canada
Beavers are associated with activity and environmental engineering. If you are “as busy as a beaver,” you are getting things done. These aquatic rodents spend most of their time in the water ...
By raising the water table in wetlands such as peatlands, they can stabilize a fluctuating water table, which influences the levels of both carbon and water. In a 2017 study of beaver dam hydrology, monitored beaver dams in a Rocky Mountain peatland were found to increase groundwater storage and regional water balance, which can be beneficial ...
If you know one thing about beavers, it's probably that they build dams. (Here are a few more things: These rodents are second only to humans in their ability to manipulate the environment, and ...
Beavers live in family units and quickly build dams on streams, creating ponds. The pools help slow the flow of water, replenishing groundwater supplies, and can also stall the spread of wildfires ...
In northern areas, they often do not repair breaches in the dam made by otters, and sometimes breach the dam themselves and lower the water level in the pond to create more breathing space under the ice or get easier access to trees below the dam. In a 1988 study in Alberta, Canada, no beavers repaired "sites of water loss" during the winter.
Beavers help keep a riparian ecosystem functioning, but on the San Pedro River, the species has struggled to maintain steady populations.
