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]

As nearly 40% of the country is currently in drought, scientists are looking to the largest rodent in North America for help: the beaver.Researchers in California and Utah found that dams made by ...
The positive effects of beaver dams on fish appear to outweigh the negative effects, such as blocking of migration. [83] Beaver ponds have been shown to be beneficial to frog populations by protecting areas for larvae to mature in warm water. [84] The stable waters of beaver ponds also provide ideal habitat for freshwater turtles. [85]

Unplanned releases can happen through escapes from zoos or wildlife centers, or through natural spread. [11] Planned releases are managed by governmental organizations and environmental non-profits. These are most successful when managed ...
Beavers create unburned islands where plants and animals can shelter from megafires, research has confirmed. A movement is afoot to reintroduce the rodents to the state's waterways.
Beaver dam, an animal construction which has a transformative effect on the environment. The beaver is a well known ecosystem engineer and keystone species. It transforms its territory from a stream to a pond or swamp. Beavers affect the environment first altering the edges of riparian areas by cutting down older trees to use for their dams ...
