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.

    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.

    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.
