International Beaver Day was first celebrated in 2009, after being created by a nonprofit group called Beavers: Wetlands & Wildlife. The group chose April 7 as the date because it is the birthday of Dorothy Richards (1894-1985), a woman who had studied beavers for almost 50 years at the Beaversprite Sanctuary in the Adirondack Mountains of New York. She had been an inspiration for Beavers: Wetlands & Wildlife, and the group’s first work was to finish reforming management of the 1,300-acre Beaversprite Sanctuary. They also have worked to stop anti-beaver legislation from being passed in several states, and have worked to find solutions to human and beaver conflicts. Eventually, they became an internationally recognized authority on beavers. In the first year of International Beaver Day, they donated almost 1,000 copies of the teachers’ edition of their DVD Coexisting with Beavers to schools.
There’s more about our day from the site above but you might have seen some of it already. What’s happening now really shows that past efforts to get the word out about how valuable we are is paying off!

In ecosystems, all species interact with each other and their environment. However, some species have a much greater influence than others. Certain plants or animals are able to greatly modify their landscape through just their mere presence. This makes them part of the group know as “ecosystem engineers.”
One of the best known examples of an ecosystem engineer is the beaver. By building dams, beavers change the flow of rivers and transform terrestrial ecosystems into wetlands. This leads to a whole cascade of processes and the arrival of new animals.
Although the individual cases of ecosystem engineers helping biodiversity are well documented, the mechanisms at work are not yet well understood. Scientists from UNIL have developed a guide for predicting and measuring the influence of species on ecosystems under different conditions. The aim of the guide is to include “ecosystem engineers” in the process of biodiversity conservation and ecosystem maintenance. The team’s review is published in Functional Ecology.
To establish this framework, the scientists proceeded in several stages. First, knowledge and literature about the known ecosystem engineers was collected. Next, the team developed a comprehensive framework to model and quantify the effects of the species. Finally, a procedure for including these natural regulators as much as possible in the field was created.
Gianalberto Losapio is the lead author of the study and a researcher at the faculty of Geosciences and Environment at UNIL. He is also affiliated with the University of Milan. He said, “This guide is intended to help specialists and communities ask themselves the right questions when setting up conservation programs. For example: What is the goal? What are the characteristics of the terrain, as well as the spatial context?”
The guide also provides tools to assess the impact of the actions carried out so that they can be adapted if necessary. “Some restoration projects end up being abandoned because introduced species cannot survive,” adds Losapio. “We believe a comprehensive approach is more likely to succeed.”
Burlington, Vt. – Ahead of International Beaver Day (April 7), PETA sent a letter this morning to Champlain College President Alex Hernandez, appealing to him to slap a fur ban on campus so as to protect beavers just like the school’s own beloved mascot, Chauncey.
PETA points out that tens of thousands of beavers are killed every year and that, as Champlain College itself points out, they were once on the verge of extinction in North America due to hunting for their pelts. With a ban, the school could help protect beavers and other animals still trapped and killed for their fur, joining Kingston University in London and the many cities that are also implementing or considering fur bans, and further the college’s mission to advance society and encourage students to help create a better world for all.
“Beavers are caught in steel-jaw traps, which clamp down with bone-breaking force, causing excruciating pain and a slow death,” writes PETA President Ingrid Newkirk. “Please help end cruelty to beavers by informing students and staff members about the threats these animals face and by establishing a fur-free campus.”
PETA’s letter to Hernandez follows.

Dear President Hernandez:
I’m writing on behalf of People for the Ethical Treatment of Animals—PETA entities have more than 9 million members and supporters globally, including many thousands across Vermont—ahead of International Beaver Day on Friday, April 7, with a dam good request that would help protect beavers like Champlain’s beloved mascot, Chauncey: Will you please ban fur on campus? This step would not only further the college’s mission to advance society and encourage students to help create a better world for all but also help protect beavers and other animals who are trapped and killed for their fur.
As you likely already know, beavers are intelligent and resourceful animals. They’re well gnawn for building dams to create ponds that offer refuge from predators and space for food storage. They also construct lodges that provide shelter and a safe place to raise their young. They’re great swimmers, and their fur is naturally oily and waterproof, which helps them keep dry and warm, even when submerged for a very long time. They’re also among the few animals who can alter their surroundings to produce a suitable home. The dams they make generate wetlands, which are vital ecosystems for many species.
Tens of thousands of beavers are killed every year, often in response to their natural dam-building efforts or so they can be used for their fur. Champlain College even points out that beavers were once nearly extinct in North America due to hunting. To trap beavers, humans often use steel-jaw traps, which clamp together with bone-breaking force, causing excruciating pain. Beavers are also often strangled in neck snares and crushed in body-gripping traps, which are barbaric devices with metal bars designed to slam shut on an animal’s body. Some traps are designed to hold beavers underwater until they drown. But since they’re used to holding their breath while they dive for long periods, death by drowning is a slow, agonizing process for them.
Please help end cruelty to beavers by informing students and staff members about the threats these animals face and by establishing a fur-free campus. Many U.S. cities have already implemented bans on fur sales, and various institutions of higher learning are considering fur bans. Your efforts to help animals would beavery impactful. Thank you for your consideration. We look forward to hearing that Champlain will be a leader on this important issue.
Very truly yours,
Ingrid Newkirk
President
We are intelligent and resourceful and do do well at gnawing trees to sustain us and make our dams, but I’m not sure if the mention above of “being well gnawn” is a punny insert or auto-correct glitch. It sorta fits though. . .

The U.S. government is looking to an unlikely rodent in an effort to repair ravaged riparian ecosystems, and it might be working.
Beavers are one of the odder species, in terms of appearance. With their long buckteeth, paddle tail and rounded shape, they don’t often attract sympathy from the owners of the land they choose to settle down on.
Due to unregulated trapping in the 1800s, beavers were largely eradicated from the U.S. This had cascading effects on the ecosystems they once called home. Beavers, as “ecosystem engineers,” change their environment in ways that promote a healthy ecosystem. With beavers gone, the riparian, or water based, ecosystems they frequented were in trouble.
Many other animals rely on the work beavers do to remain healthy. Without beavers, fish populations, predators, birds, amphibians and even the plants lining water banks were suffering.
Since 2008 the Okanogan-Wenatchee National Forest has been reintroducing beavers to various areas in order to promote riparian health. According to the United States Department of Agriculture, the project has documented an increase in salmonid spawning and rearing as a result of the beavers’ presence.
In Idaho there are between 50 and 75 beaver restoration projects currently operational. These projects either directly introduce beavers to damaged riparian areas or have biologists build dam-like structures in order to encourage beaver populations to return to those areas.
The U.S. has a history of killing off vital species, directly resulting in whole ecosystems decaying; a cursory examination of the history at Yellowstone National Park can attest to that. The eradication of wolves, grizzly bears, mountain lions and, of course, beavers have all resulted in the lack of riparian vegetation, predatory species and healthy landscapes.
It brings hope to the environmental community seeing these restoration projects underway, reversing the damage once done to the American landscape. Recent legislation, like Idaho’s SB 1211 and Utah’s HB 469, attempt to undo some of those efforts, but biologists and conservationists are not so easily deterred.
The beaver represents a great success in conservation; once nearly extinct, there are now almost 15 million in North America alone thanks to supremely dedicated conservationists.

But coexistence is key. We just want to get along without hurting anyone. So maybe you can help out these friendly folks.
Humans often kill beavers when their damming and tree-chewing behaviors cause problems such as flooding and destroyed vegetation. This approach is ineffective because new beavers will soon move into the empty habitat. Lethal trapping, dam destruction, and culvert unclogging are only temporary solutions that, in the long-run, are expensive and unsustainable.
How is coexistence possible?
Beavers and the wetland habitats they create are beneficial to people, plants, animals, and entire landscapes and watersheds. We believe it is possible for people to share land with live beavers while addressing flooding and tree-chewing problems using long-term, cost-effective solutions.
Got some images of kids playing beaver at the recent SLO County Beaver Festival.
Yay!!! April 7th is INTERNATIONAL BEAVER DAY!
