Beavers love splashing around in ponds, lochs and rivers and have amazing adaptations for living in water. They have skin flaps in their ears and nose to keep water out, and they can chew under water without swallowing water as their lips close behind their front teeth!
Although beavers are native to the UK, they were hunted to extinction in the 16th century. The Scottish Wildlife Trust and the Royal Zoological Society of Scotland helped return these amazing animals to Scotland in 2007, at Knapdale in Argyll. Today, about 1000 beavers are living in over 250 places around Scotland!
Beavers build using natural materials in their woodland habitat, and can even fell trees by gnawing through them. They don’t waste anything, eating the bark and the vegetation and using the trunk and branches for their construction work. The dams can help create new wetlands, restore native woodlands, and benefit lots of other species such as dragonflies, otters, and fish. That’s why beavers are known as ‘ecosystem engineers’!
Challenge yourself to beating the beavers! Can you create a watertight dam? Follow the instructions below to find out how…
What you will need:
- A tray (needs to be watertight)
- Foraged materials (such as twigs, leaves, rocks, grass and mud)
- Water (to pour)
How to build your beaver dam:
- To make the beaver dam, must first forage for the materials outside. Head out on a walk and try and collect things like twigs, rocks, leaves, grass and mud.
- Now it’s time to assemble your dams. In the middle of your tray, create a strong dam with things you found.
- Pour water into one side of the tray and see how long it takes for water to pass through the dam to the other side. Beavers don’t quit so have another go if you see a way to make it better!
Top tip: Fill any holes with mud and use branches to make it strong!
