Facts About Beavers
So why exactly did Canada pick the beaver as its national symbol? stop growing and chewing on trees helps to keep the teeth from getting. But beyond their bucked teeth and busy behavior, what do you really know about them? from getting in, and a thick, oily coat that keeps the water and cold at bay . The tail can grow to be 15 inches long and 6 inches wide. The beaver's extra large lungs and liver keep its blood well oxygenated. The sound of running water, especially coming from the dam, triggers a Beavers and muskrats do much of their work with mouth and teeth, but they.
Their pelts were in high demand for the fashion industry in Europe, and their castoreum was used for a variety of purposes.

But what may come as a surprise is the extent to which they were hunted. The beaver was nearly wiped off the continent. It's estimated that they numbered between million when Europeans arrived and by the early s, they were nearly gone.
Indeed, much of the western exploration of the U. Today, after significant conservation efforts starting in the mids, numbers have rebounded to an estimated million. Eurasian beavers have been heavily trapped as well, also for fur and castoreum.
In fact, they were so heavily trapped that they became extinct in the United Kingdom for years. Several thousand now live along the Elbe and Rhone, and they are rebounding in other parts of Europe. In Great Britain, they were reintroduced in Gloucestershire in OctoberLancashire inand they were reintroduced in Scotland in Beavers can turn forests into ponds and meadows Beavers are industrious animals and are responsible for clearing patches of forest into wetlands and meadows.
Wetlands and Wildlife website. Indeed the scope and long-lasting changes that a beaver family can bring to an ecosystem is incredible.
Why is the Beaver Canada’s National Symbol?
If a beaver moved into a forested area that's a little too dry for its liking, the beaver simply gets to work changing the landscape to suit its needs. By damming up streams and creeks, a beaver cuts down forest and creates huge ponds that provide water to other wildlife even during the height of summer. When they leave an area, and the dam breaks down, the flooded area dries and becomes a meadow. The chemical changes alter the type of invertebrates, and the new water source attracts new species of birds, fish and amphibians.
Flooded timber dies off and a forest becomes an open water ecosystem. As they return to habitats where they once flourished, they take no notice of the people who have built houses, roads and entire towns within the flood zones their dams create.
While many celebrate the return of beavers, their presence causes grumbling when their engineering feats and our engineering feats collide.
Beaver dams help with pollution A reduction in pollution is among the many effects beaver activity has on landscape. A recent study by scientists from the University of Rhode Island measured just one of the positive benefits of dams: They can help remove up to 45 percent of harmful nitrogen from streams and creeks.
According to the Potomac Conservancy: Nitrogen is one of the most problematic pollutants in the Potomac and the Chesapeake Bay. Nitrates, nitrogen-based chemicals found in fertilizers and other chemical compounds, wash off agricultural and urban areas after rain in the form of polluted runoff. Wastewater treatment plants also contribute to the problem. These chemicals cause algae blooms, which in turn result in dead zones, underwater areas devoid of oxygen where fish and other aquatic life struggle to survive.
The ponds that build up behind beaver dams encourage aquatic plants to grow, and their decomposition at the bottom of the pond encourages bacteria growth, the study found.
The bacteria breaks down these nitrates, releasing nitrogen as a gas. The result is cleaner water, all thanks to beavers. The answer may be in part in this well-known rodent. Teaming up with nature's best waterway engineers could make a difference for water-parched places. Beaver create dams to make ponds, their favorite place to live. Dams are created by weaving branches together, felling trees by cutting them down with their teeth, and waterproofing the construction with mud.
Dams can be several meters in length and up to 6. Beavers also dig canals to bring water from large bodies of water to their feeding area. Beavers have a tremendous impact on ecosystems. Dams alter the flow of rivers and can flood hundreds of acres.
Dams prevent erosion and raise the water table, which helps purify the water as silt builds up and breaks down toxins, according to ADW. As sediment and debris build up, carbon increases and nitrogen decreases. The chemical changes alter the type of invertebrates, and the new water source attracts new species of birds, fish and amphibians.

Over time, abandoned dams decay, and meadows appear. Impact of Beaver Dams Wider Than Thought ] Top hats made of beaver pelts were the height of fashion in the 19th century. Unlike other mammals, beavers can digest cellulose, which is a major component of their diet, according to ADW. Beavers eat leaves, roots and bark from aspens, willows, maples and poplar trees. They also eat aquatic plants.

Offspring Beavers are very social and live in groups called colonies. One lodge is often the home for a monogamous couple, their young and the yearlings born the year before.
Beavers mate during the winter, from January to March. The Eurasian beaver has a gestation period of around 60 to days. Then, they give birth to one to six babies that weigh around 8. Baby beavers are called kits. Eurasian kits are usually weaned after six weeks of life. American beavers have a gestation period of around to days. They give birth to one to four kits that weigh around 9 to 21 ounces to g.
American beavers are usually weaned in around two weeks. At around 2 years of age, the kits leave the lodge and make one of their own. At 3 years, they find a monogamous mate.
