Good question! The inlet end of the pipe is suspended in the middle of the cage, reducing the feeling of flowing water thus reducing the beaver's instinct to try to plug it. If they do feel some flowing water, the surface area of the cage is much too large from them to effectively plug it, even if they try. Additionally, this is one reason why the pipe is extended approximately 40 feet into the pond, far away from the outlet end which produces the sound of running water. By having the inlet and outlet ends far apart, the beaver can't usually figure out where the leak in the dam is coming from or how to fix it. I have not heard of a beaver successfully plugging the cage on the inlet end but it's something to monitor for.

I don't think you watched all the way through. The cage is meant to discourage them from building, not kill them.

The size is also to make it more difficult for them to build. Please watch your content thoroughly before giving a poorly educated opinion.

Great question! We do our best to monitor all of our install sites yearly or ask partners how they are functioning. Pond levellers require maintenance checks once or twice a year to ensure they are working properly and to clear any vegetation or debris that may build up if it's installed in a shallower pond. Occasionally the pond leveller requires adjustments such as the installation of a protective grate on the outflow end of the pipe, but most of the time this is not necessary. To see examples of other pond levellers installed in Alberta, please visit our Map of Beaver Coexistence Tools (www.rockies.ca/beavers/map.php)

@@Miistakis thank you.

Great question! Although that is possible it's unlikely and we've never heard of that happening at a site. It's unlikely because the beaver is motivated by the sound and feeling of the water flow created at either end of the pipe (outlet in the dam, and inlet which is placed in the pond). The inlet is protected by the large wire cage so the flow created is not as strong since the pipe sits in the middle of the cage. Essentially they cannot figure out where the source of the "leak" in the dam is located so do not know the pipe is involved at all. They will sometimes dam the end of the pipe but it's difficult since they are working against the flow of the water, and if this happens, metal fencing can be applied at the outlet as well.

If they damage it in a few years they'll just install a new one. Doesn't look super expensive.

Exactly. This is why it's recommended that the exclusion fence is checked several times per year to ensure any debris that gets stuck against the fence is cleared away. This is much less time consuming than clearing a plugged culvert.

Hi there, thanks for your comment. Although beavers are incredibly intelligent, the unique trapezoidal shape of the exclusion fence is highly successful with a 95% success rate when installed in an appropriate location (not every site is ideal for exclusion fencing). The shape allows the sticks/debris/mud that beavers place on the fencing, to be washed to the side of the culvert exclusion fence. Regular maintenance (1-2 times per year) is required to ensure the debris isn't building up along the sides.

That must be why this got recommended to me.

Soon as I saw this video pop up I knew why as well LOL. They need to contact him and make sure they did this correctly.

I bet he doesn't. He makes a lot of money through UA-cam. Solutions like this kill his opportunities.
