Why are beavers obsessed with dams? - Glynnis Hood
Explore how beavers build their impressive dams, and what impact these structures have on the surrounding environment.
--
Nestled in the forests of Canada sits the world’s longest beaver dam. This 850-meter-long structure is large enough to be seen in satellite imagery and has dramatically transformed the region, creating a pond containing 70 million liters of water. But dams of any size can have huge impacts on their environment. So how exactly do beavers build these impressive structures? Glynnis Hood investigates.

Also worth noting: Beaver dams trap sediment and nutrients at the bottom of the pond, so when dams are abandoned (say, due to an exhaustion of suitable food sources) and fall into disrepair, the drained pond becomes the site of rich meadows, which support a host of additional species.

@@iridium8341 Really? I wasn't aware that beavers blew up mountains to mine toxic and radioactive materials, or replaced massive tracts of vegetation with impermeable pavement, or produced massive quantities of non-biodegradable waste. (And by the way, most of their favored tree species readily coppice, so unlike humans, they don't utterly destroy forests.) As for goats, they weren't the ones who killed off most of the predators that force them to move from place to place, thus preventing long-term damage from intensive browsing.

@@sasukedemon888888888 There are two species of beaver in the world, North American and Eurasian. The main differences, among others, is that the Eurasian species is slightly larger, has shorter fur and the tail is less round. They were hunted to near extinction here in Europe for their fur and castoreum (used in perfume and medicine).

@@itzurboyyapper No. Eurasian Beavers used to be native to Britain before they were hunted to extinction; now we're bringing them back.
Beavers are really like environmental engineers! Our crew filmed a project that aimed to bring wilderness back to the UK. We had a chance to talk to a couple who managed to get Eurasian beavers back to Cornwall to transform their farm into a biodiversity hotspot. Beavers are constantly working, building dams, cutting down trees or building a lodge. And this is key to sparking new life into the wilderness. We're curious to see how the farm in Cornwall will respond after the reintroduction of beavers.
So, Beavers are architects after all. Amazing. I could learn a lot from them.😉😄

I would agree that the animation is great. The character designs are very pleasant for the eyes, and the animation in general reminds of the rubber hose style. However, in my honest opinion, there was a major issue; the backgrounds. It is completely fine to have a background that is in a different style in comparison to the animation, because that would make the characters stand out, as we've seen that being used brilliantly with "The Amazing World of Gumball", and it allows the characters to be in an atmosphere that is different from what they would typically be associated with, but unfortunately the colour palette and overall colours used for the backgrounds in this video were too vibrant. Which made it difficult to focus on the characters-since everything blended into the background. Improvement? My suggestion wouldn't necessarily be to remove the papier mâché background, but instead, what I am advising is for them to improve the colour scheme. Following the colour theory, and keeping the saturation, contrast, value (brightness/darkness), and hue in a coherent manner.

The animation style reminds me a lot of Ren and Stimpy. I loved that show!
I liked this a lot but I would have preferred to see some footage of actual beavers mixed with the animation which was a bit overblown at times - enough to actually detract.
The animation reached a level of abstraction that made this harder to understand and visualize than necessary in my opinion.
I've always been interested in beavers and this video catches my attention about them even more. It's just so cool how they're able to build little fortresses for themselves.
I just realized how smart beavers are..

I recall seeing beavers during my childhood on the Bull River in Montana.
Wow! They are so clever. 😁👍🏿
Dam! That's crazy!
I did not see an answer to the Why. I would speculate that the two reasons are: Food and safety. It is like their greenhouse. But few predators dive to reach the underwater access to their home.
Ha ha ha!! 3:35 to 3:38 is like The Brady Bunch, but with BEAVERS!!!! Ted-Ed, you cracked me up with that one! Legends never die, man... The legend that is The Brady Bunch show does not know how to die...

Gotta love 'em beavers.
This was a dam good video.
Here in northern BC Canada, we must have the world's laziest beavers. I live next to a very large natural lake and when I'm out in my kayak I see beavers all the time just frolicking in the natural lake not carrying or building anything. I guess they figured 'hey, why build a dam if there's already a huge lake here'. I can relate. But then again, no, could they have ... ? It's an 80 km long lake.
By loyalty, determenation, and the power of friendship!
Beaver dam + flood waters = mobile home lol
Reminds me of the days I used to watch Angry Beavers.
I love it!. I think they are the most intelligent animals. God bless these animals
Ted ed is basically the channel that answers ever question we were wondering when we were children.
If there’s a French version of this video, the bio dome in Montreal should play it for their beaver section.

Due to lack of trapping, beavers have been becoming more into my town in Canada 🇨🇦, I’m on the waterways and rivers in my home we could see sometimes trees that have bite marks, or taken down by beavers 🦫 one even wrecked a fence 😂
Nice beaver

I read that title veeery differently hehehe
Beavers are such underrated animals they work so hard I can feel the logs coming inside me
While studying about dams in civil engineering, i read the largest wooden dam in the world is beaver dam. I thought it's the name of a dam
Who at first only subscribe for the vids that were riddles but now actually watch’s the other vids.
Excellent lesson, very informative! One critique; the animation on this one is just terrible. 😬
To my family beavers were not helpful, my family had a pond that had once almost 5 beavers in it at once, and they didn’t help. Well they did increase the water level, but that almost destroyed a manmade dam that would of flood hundred of trees.
Cool
I love science
