Beavers have occasionally wandered into Downtown Ottawa, including Parliament Hill, Major's Hill Park, and Sparks Street. [83] Beavers caught in the urban core of Ottawa by the National Capital Commission's conservation team are typically brought to a wildlife centre, and later released near the Ottawa River, close to the Greenbelt.

Wetlands also aid in water filtration by removing excess nutrients, slowing the water allowing particulates to settle out of the water which can then be absorbed into plant roots. Their vegetation and soil trap sediments and pollutants, while beneficial microbes in the wetland break down harmful substances. In this manner, these invertebrates ...
Beavers have also been shown to maintain habitats in such a way as to protect the rare Saint Francis' satyr butterfly and increase plant diversity. [ 9 ] Biodiversity may also be affected by ecosystem engineer's ability to increase the complexity of processes within an ecosystem, potentially allowing greater species richness and diversity in ...
The state has made available roughly $2 million in grant funding to landowners for these nonlethal methods, which can include sand-paint mixtures to deter beavers from chewing through trees ...
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 ...
Structures formed from plant material include beaver dams, which are constructed by foraged branches and sticks. [22] The dam is a wall of sticks constructed on a moving water source, which forces the water to collect in one area and to stop flowing. [22] Beavers begin to build a dam in an area where rocks and other debris slow the flow of the ...
A beaver dam or beaver impoundment is a dam built by beavers; it creates a pond which protects against predators such as coyotes, wolves and bears, and holds their food during winter. These structures modify the natural environment in such a way that the overall ecosystem builds upon the change, making beavers a keystone species and ecosystem ...
Managers of the watershed of the Enzo Creek Nature Sanctuary experienced the all too common problem with beavers: their tenacious desire to dam water. The water level at Enzo Creek Nature Sanctuary had been growing year after year, impacting the fauna in Hunt Marsh, an 18-acre (73,000 m 2) wetland which serves as both a waterfowl nesting area and refuge.
